Histology

The brain has the most complex tissues in the human body. It contains billions of neurons and glial cells that work together to support various cognitive functions such as thinking, memory, and emotions.

Chloragogen tissue is a type of tissue found in some invertebrates, such as earthworms and certain insects. It functions as a storage and detoxification site for waste products, similar to the liver in vertebrates. It contains granules that can store substances like glycogen, lipids, and heavy metals.

Protective tissue in roots helps prevent damage from physical injuries, pathogens, and environmental stresses. It also aids in water and nutrient absorption, as well as in preventing excessive water loss through evaporation. Overall, protective tissue plays a crucial role in maintaining the health and functioning of root systems.

The four histological layers of the gut are the mucosa, submucosa, muscularis externa, and serosa (or adventitia). The mucosa is the innermost layer, containing epithelial cells and glands. The submucosa provides support and contains blood vessels and nerves. The muscularis externa is responsible for peristalsis, and the serosa (or adventitia) is the outermost layer providing protection and support.

The cells of heart muscle are striated (like stripes on a tie) as is skeletal muscle. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart. They can contract but also carry an action potential (i.e. conduct electricity), like the neurons that constitute nerves. Some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. That is they beat on their own and in union with each other.

Pseudostratified ciliated columnar epithelium have projections called cilia, which help in moving mucus and particles along the surface of the tissue. These projections aid in maintaining the health of the respiratory system by trapping and removing harmful substances from the airways.

The study of anatomy at the microscopic level is called histology, which is further divided into cytology (the study of individual cells) and histopathology (the study of tissues). Histology involves examining tissues and cells using a microscope to understand their structure and function.

Smooth tissue refers to a type of tissue that lacks striation and is typically found in organs like blood vessels and the digestive tract. Muscle tissue encompasses three types: skeletal muscle, cardiac muscle, and smooth muscle. Smooth tissue is a specific type of muscle tissue known as smooth muscle tissue.

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.

well i dont think it can because fire cant really beat water can itwell i dont think it can because fire cant really beat water can it

The inward folds of cerebral tissue are known as sulci. They are grooves or furrows that separate the gyri, which are the raised folds of the cerebral cortex. Sulci increase the surface area of the brain, allowing for more complex functions to be carried out.

• looks as if it is more than one layer, but not all cells reach free surface
• often has goblet cells and cilia
• the function is secreting and moving mucous
• found in the repiratory tract from nose to bronchi, and some parts of the male reproductive tract.

Plant tissues should have a distinct cell wall, as well as a cell membrane. They are usually more rigid in shape and organised into a pattern. They will have small green organelles (chloroplasts) inside the cell, as well as one large, central vacuole.

Animal cells will have more irregular shapes, no cell wall or chloroplasts, and many small vacuoles (instead of one large one).

The most common histology stain used for brain tissue is hematoxylin and eosin (H&E) staining. This stain allows for visualization of the overall tissue architecture, cell morphology, and distinguishing between different cell types in the brain. Other stains like Nissl stain can be used to highlight neuronal cell bodies and their distribution in the brain.

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.

Epithelial tissue or more simply epithelium covers and lines body surface and forms glands. Cells of epithelium are very set very close to each other, neighbouring cells are held together by cell junctions or desmosomes. The desmosomes of macula adherens made of tonofibrils. The epithelial tissue rests on a thin extracellular basement membrane, secreated partly by epithelial cells and partly by underlying connective tissue. Epithelial cells may have microvilli, sterocilia, kinocilia or flagella. They are of two types: connective and lining epithelium and gladular epithelium

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.

When I had my fungal bladder infection the symptoms were exactly the same as a normal bacterial UTI in fact the doctor in the ER treated it as a bacterial bladder infection it wasn't until I went to my primary doctor and had more testing done just 2 days later that it was found to be fungal. The only thing that was different was that there were large floating particles in my urine my doctor told me these were collanies of fungi the smell of my urine was different than when I had bacterial bladder infections. Mind you I have had several bacterial UTI's. I hope this helps you If you do have a fungal bladder infection and are female they need to check and see if you have the same infection in you vagina.

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.

Because the endometrium is an epithelial tissue. Collagen and elastic fibers are produced by Fibroblasts which are found in connective tissue not epitheliam. Does that answer your question? Or do you want a more indepth response?

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.

there are three types of tissues which it is the smooth ticcues which it is responsible for the movement of the iside and we can't control it and the second one is paced everywhere in the body and we can contol it and mainlu it is resposible for the movement we make like walking and grabing a glass of water, the third one is the one that is replaced in the heart and it is called the heart tissues

Ciliated epithelium is located in the lining of most body cavities. Some of the cavities that have ciliated epithelium are the lungs, trachea, and nose. Ciliated epithelium serves to keep dust and debris out of the lungs and control the flow of mucus.in your lungs . Its The tissue in your lungs!!In the respiratory tractThe ciliated epithelium is a type of tissue located inside the nose. Cilia or nose hairs are situated on top of the ciliated epithelium and triggers sneezing when dust particles are caught in the cilia.In what organ will you find ciliated epithelium? Primarily in the trachea.
