Pathology

Dehydration leads to a decrease in cell volume and affects the functions within cells, such as nutrient uptake, waste removal, and signal transduction. It can disrupt the balance of electrolytes inside and outside the cell, impacting enzyme activity and overall cell function. Severe dehydration can eventually lead to cell damage or even cell death.

The production of blood cells is called hematopoeisis, and it is the process by which all the different blood cells are formed from a single kind of hematopoeitic stem cell. All of the body's blood cells start out in medullary portion of bone--the marrow--except in some fetal stages and in some disease states, where blood cells can be produced in the liver and spleen (this is called extramedullary hematopoeisis). Most of the cells produced in the bone marrow mature into their final forms in the bone marrow, but some white blood cells finish maturation in the thymus. The stem cells and their progeny (daughter cells) receive various stimuli in the form of chemicals that contact them that "push" them in the direction of forming whatever blood cells the body happens to need.

No, semen is primarily made up of sperm cells produced in the testes and various fluids produced by accessory glands. Epithelial cells are not typically found in semen.

Powder microscopy is evaluation/quality control method, used for medicinal plants to study the specific microscopic characters using different staining reagent. Applications in detection of adulterants in sample by performing comparison study using authenticated sample.

Cell injury refers to any damage or disruption to a cell's structure or function caused by various insults. Cell death is the irreversible cessation of cellular activities and functions, leading to the demise of the cell. Cell death can occur through different mechanisms, including apoptosis and necrosis.

Dehydration can affect almost every aspect of health, including sexual function. When a person is dehydrated, they are tired and won't have the stamina that a normal person would. They also have less fluid in their bodies, so they would have less ejaculate and less lubrication. It can also lower blood pressure so the person may feel more lightheaded and not perform as well.

Adrenaline can help to temporarily reduce bleeding by constricting blood vessels and increasing blood pressure. However, it is not a long-term solution for stopping bleeding and should not replace proper medical treatment for significant injuries.

No, pathology is a general non-specific noun. However, you would capitalize it if it were part of a title, such as Department of Pathology.

Cytology is the branch of biology that focuses on the study of cells, their structure, function, and interactions with other cells. It involves the examination of cells under a microscope to understand their characteristics and behavior. Cytology plays a critical role in various fields such as medicine, research, and forensics.

Without hair in your nose and cilia in your trachea, foreign particles like dust, dirt, and pathogens could enter your respiratory system more easily. This could increase the risk of respiratory infections, irritations, and other health issues. Hair and cilia help to filter and trap these particles, preventing them from reaching deeper into your lungs.

The process by which red blood cells are produced is called erythropoiesis. It occurs in the bone marrow and is regulated by the hormone erythropoietin, which stimulates the production of red blood cells from stem cells. Erythropoiesis is essential for maintaining a stable supply of red blood cells in the body to carry oxygen to tissues.

A granum is a stack of thylakoid discs in the chloroplast of plant cells where photosynthesis takes place. It is the site where light energy is converted into chemical energy through the process of photosynthesis.

One important abiotic factor in all ecosystems is sunlight. It is essential for photosynthesis, the process by which plants and some other organisms convert sunlight into energy. Sunlight also impacts temperature, which in turn affects the overall climate of an ecosystem.

Platletes are the fractions of cells that are invilved in blood clotting to stop a heamorage. If a blood vessel is burst a zymogen (a precurser for a protien) called Fibrinogen is cleaves to form Fibrin. These Fibrin molecules are long chains that join together to form a mech over the breach in the vessel. The mesch can easily stop red blood cells being lost but much plasma is still able to freely flow away. Platelets are just the right size to get caught in the mesh and block of the gaps. More layers are formed over each other eventually makinga sheet of mech with platelets trapped in it blocking anyhting from escaping the system.

Sociology is the scientific study of people, including but not limited to collective behavior, social institutions, and social norms, utilizing specified theoretical approaches. Anthropology is closely related to sociology, and is dedicated to the study of cultures both past and present. Speech-language pathology is primarily an applied science, dedicated to understanding and remediating communication and swallowing disorders in people of all stages of life, from birth to death. The studies of both sociology and anthropology are likely to enhance the understanding of speech-language pathology, and vice versa. An effective speech-language pathologist recognizes the impact of social norms and institutions on verbal and nonverbal communication, cultural customs and rules surrounding eating/drinking, the importance of cultural perspective when addressing ability and disability, and the impact that access to resources and current educational and health care institutions have in determining who receives services for speech-language and swallowing disorders. Sociologists seeking to deepen understanding of disability across cultures, the social impact of communication disorders, and the current system of service provision for communication and swallowing rehabilitation would benefit from utilizing this understudied group of professionals. Sociolinguistics and the sociology of language are two sciences that are closely tied to sociology, anthropology, and speech-language pathology.

A post mortem is a general examination after death to determine the cause of death, while an autopsy is a more detailed medical examination of a body after death to investigate the cause and manner of death. Autopsies involve a more comprehensive examination of organs, tissues, and bones to gather more specific information, whereas post mortems can be more general and less intense in their scope.

Forensic means "used or applied in the investigation and establishment of facts or evidence in a court of law, as in "forensic photograph" or "forensic ballistics." Therefore, forensic pathology is the study of abnormal conditions of the human body that may need to be debated in court. A forensic pathologist might work in a medical examiner's office or be a coroner.

General pathology deals with the identification of diseases and abnormal conditions of the human body in general. General pathologists work for hospitals or laboratories, usually in connection with surgeons or tissue samples from other sources, to determine the presence of disease.

Pathology is the study of diseases, so a pathology department would be the department where diseases are studied.

A variety of jobs are available depending on what specialization of speech pathology you choose to train for. Some possibilities are working in rehab hospitals, being employed by a school district to help students, becoming a supervisor, or becoming a consultant for insurance companies. You can also go into corporate speech pathology and do accent reduction training or train speakers in effective presentation.

A master's degree is the most common level of education among speech-language pathologists. Licensure or certification requirements also exist, but vary by State. Education and training. Most speech-language pathologist jobs require a master's degree. In 2007, more than 230 colleges and universities offered graduate programs in speech-language pathology accredited by the Council on Academic Accreditation in Audiology and Speech-Language Pathology. While graduation from an accredited program is not always required to become a speech-language pathologist, it may be helpful in obtaining a license or may be required to obtain a license in some States. Speech-language pathology courses cover anatomy, physiology, and the development of the areas of the body involved in speech, language, and swallowing; the nature of disorders; principles of acoustics; and psychological aspects of communication. Graduate students also learn to evaluate and treat speech, language, and swallowing disorders and receive supervised clinical training in communication disorders. Licensure and certification. In 2007, 47 States regulated speech-language pathologists through licensure or registration. A passing score on the national examination on speech-language pathology, offered through the Praxis Series of the Educational Testing Service, is required. Other usual requirements include 300 to 375 hours of supervised clinical experience and 9 months of postgraduate professional clinical experience. Forty-one States have continuing education requirements for licensure renewal. Medicaid, Medicare, and private health insurers generally require a practitioner to be licensed to qualify for reimbursement. Only 12 States require this same license to practice in the public schools. The other States issue a teaching license or certificate that typically requires a master's degree from an approved college or university. Some States will grant a provisional teaching license or certificate to applicants with a bachelor's degree, but a master's degree must be earned within 3 to 5 years. A few States grant a full teacher's certificate or license to bachelor's degree applicants. In some States, the Certificate of Clinical Competence in Speech-Language Pathology (CCC-SLP) offered by the American Speech-Language-Hearing Association meets some or all of the requirements for licensure. To earn a CCC, a person must have a graduate degree from an accredited university, 400 hours of supervised clinical experience, complete a 36-week postgraduate clinical fellowship, and pass the Praxis Series examination in speech-language pathology administered by the Educational Testing Service. Contact your State's Licensing Board for details on your State's requirements. Other qualifications.Speech-language pathologists should be able to effectively communicate diagnostic test results, diagnoses, and proposed treatment in a manner easily understood by their patients and their families. They must be able to approach problems objectively and be supportive. Because a patient's progress may be slow, patience, compassion, and good listening skills are necessary. Advancement. As speech-language pathologists gain clinical experience and engage in continuing professional education, many develop expertise with certain populations, such as preschoolers and adolescents, or disorders, such as aphasia and learning disabilities. Some may obtain board recognition in a specialty area, such as child language, fluency, or feeding and swallowing. Experienced clinicians may become mentors or supervisors of other therapists or be promoted to administrative positions.

A coliform count is a microbiological assay of the number of coliform-type bacteria living in a certain sample. This is often used as a measure of fecal contamination of water supplies.

Pathological fatigue can be due to the after effects of illness or be an indication of some kind of underlying disorder such as diabetes or a defective thyroid. This will require treatment under guidance from your physician.

When the leukocyte count is high, the physician should suspect either an infection or cancer, as these are the two most common reasons for an elevated leukocyte count. Depending upon the rest of the physical examination and the results of the rest of the blood tests, your physician may already know which of the two it is.

A skin biopsy is used to make a diagnosis of many skin disorders. Information from the biopsy also helps the doctor choose the best treatment for the patient.
