Ciliated epithelial cells line much of the respiratory tract. These cells have hair-like structures called cilia that help to move mucus and particles up and out of the airways to prevent infections and keep the lungs clear.
Ciliated epithelium is a type of epithelial tissue that has specialized cells called cilia on the surface. These hair-like projections give the tissue a brush-like appearance and are important for moving substances along the surface, such as mucus in the respiratory tract or eggs in the fallopian tubes.
A tissue is considered a target tissue when it has specific receptors for a particular hormone or chemical signal. These receptors allow the tissue to respond to the signal by initiating specific biological responses. Target tissues are often the primary sites where the hormone or signal exerts its effects in the body.
Fungal infections in the bladder are not common but can occur, especially in immunocompromised individuals. Symptoms may include pain or burning during urination, frequent urge to urinate, cloudy or bloody urine, and abdominal or pelvic pain. It is important to follow up with your healthcare provider for proper diagnosis and treatment based on the urine sample results.
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
Ciliated epithelium is a type of tissue in the human body that contains hair-like structures called cilia. These cilia help move substances along the surface of the tissue, such as mucus in the respiratory tract. Ciliated epithelium is found in areas like the respiratory tract, fallopian tubes, and parts of the brain.
Squamous histology refers to tissues or cells that have a flat, scale-like appearance when viewed under a microscope. This type of histology is characterized by thin, flat cells with a centrally located nucleus. Squamous epithelial cells line the surface of the skin and many organs, providing a protective barrier.
The endometrium is constantly undergoing changes in response to hormonal signals during the menstrual cycle. The abundance of cells contributes to its regenerative capacity. Collagen and elastic fibers are not present because they would restrict the endometrium from being able to thicken and shed during menstruation.
Ciliated epithelium is found in areas where movement of particles, such as mucus and debris, is important. It is commonly found in the respiratory tract, fallopian tubes, and parts of the reproductive system. The cilia help to move substances along the surface of the epithelium.
Animal tissues include epithelial tissue (covers and protects), connective tissue (supports and binds), muscle tissue (contracts and moves), and nervous tissue (transmits and processes information). Plant tissues include dermal tissue (protects and prevents water loss), ground tissue (stores nutrients and provides support), and vascular tissue (transports water and nutrients).
Ciliated epithelium is found in the respiratory tract, where it helps to sweep mucus and foreign particles out of the airways. It is also present in the fallopian tubes to help move the egg towards the uterus and in the lining of the trachea to remove debris.
Histology is the study of tissues at a microscopic level, and it can provide valuable insights into the structure and function of cells and tissues in the body. It can help in identifying abnormalities, diagnosing diseases, understanding the progression of diseases, and guiding treatment decisions. Histology is crucial for medical fields such as pathology, anatomy, and research.
Tissue complementation refers to the process of matching the tissue type of a donor with that of a recipient to minimize the risk of rejection in transplantation. By ensuring compatibility at a genetic level, tissue complementation can improve the success of organ and tissue transplants.
Cuticle is not considered a tissue because it is a non-living protective layer made up of waxes and cutin that covers the outer surface of plant organs. Tissues are made up of living cells working together to perform a specific function, whereas the cuticle is a barrier formed by secretion and accumulation of materials.
The histology of the uterus from inside to outside consists of three layers:
In plant histology, iodine is commonly used as a stain to detect the presence of starch in plant tissues. Iodine reacts with starch molecules, forming a blue-black color complex. This staining technique helps identify storage tissues such as roots, tubers, and seeds, where starch is abundant.
The standard preparation of a histological specimen involves several steps. First, the tissue is fixed in a suitable fixative solution, such as formalin, to preserve its structure. Then, the tissue is dehydrated by passing it through a series of alcohol solutions. After dehydration, the tissue is embedded in a support material, typically paraffin wax. Thin sections of the embedded tissue are then cut using a microtome and mounted on glass slides. Finally, the slides are stained to enhance the visibility of cellular structures and evaluated under a microscope.
Tissue type of the epidermis is stratified squamous epithelium.
Microtomes are used to cut very thin slices of a specimen in order to examine the specimen microscopically.
Secondary lymphoid organs and tissues are the sites where lymphocytes are most active. The white pulp of the spleen is the common site for plasma cells to develop. Macrophages are also active in the spleen red pulp; where they engulf blood-borne antigens to be presented to T lymphocytes in the circulation.
Yes.
Acutely from burns and/or smoke inhalation OR from explosive shock.
(Note - all these can kill you immediately, before scaring occurs. But if you look like you're getting better and then you die, it may well be from the scaring.)
Chronically from an accumulation of micro scars (usually from smoking cigarettes) which is clinically diagnosed as emphsema.
The scientific is used in real life by everyone on a daily basis. Some real life examples would be cooking, growing plants, or even diagnosing a medical problem.
The field of histology is growing but the number of people entering the field is shrinking very rapidly. Therefore the salary of histologists varies greatly. A typical histologist fresh out of school with the ASCP (HT) certification will be hired at an hourly rate of 20.00-22.00. This is the starting pay for someone living in New England. After being emlpoyed in the field for 5 years the pay scale can also vary depending on what areas of histology a person has become proficent in, the more the better. The average pay scale would be from $25.00 to $30.00 an hour. After 10 consistant years in the field one will make between $30.00 to $50.00 an hour. These figures will go up dramatically in the next ten years because, the average age for a histologist today is 55 years old. This means that in 7-10 years 1/3 to 1/2 of the histology population will retire.
