What is the histology of the uterus from inside to outside?

User Avatar

Asked by Wiki User

The histology of the uterus from inside to outside consists of three layers:

  1. Endometrium: The innermost layer composed of simple columnar epithelium with underlying stroma. It undergoes cyclic changes during the menstrual cycle.
  2. Myometrium: The middle layer composed of smooth muscle fibers arranged in different directions providing strength and contractility to the uterus.
  3. Perimetrium: The outermost layer of the uterus composed of a serosa or adventitia, depending on its location in relation to other organs.

What is the function of iodine in plant histology?

User Avatar

Asked by Wiki User

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.

What is standard prepration of a histological specimen?

User Avatar

Asked by Wiki User

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.

'uses of microtome in histology'?

User Avatar

Asked by Wiki User

Microtomes are used to cut very thin slices of a specimen in order to examine the specimen microscopically.

What is secondary lymphoid tissue?

User Avatar

Asked by Wiki User

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.

Formation of scar tissue in the connective tissue of the lungs is a condition?

User Avatar

Asked by Wiki User

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.

Do histology tech make good money?

User Avatar

Asked by Wiki User

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.

Why is cuticle not a tissue?

User Avatar

Asked by Wiki User

A cuticle is not tissue because it is a stack of chemicals. This chemical stack just sits on top of the layer of cells. Tissue is a group of cells that perform a function, while a cuticle is just a simple coating.

What tissues are affected in Atherosclerosis?

User Avatar

Asked by Wiki User

Atherosclerosis is a disorder that affects your heart and blood vessels that support it. Atherosclerosis is also known as the hardening of the arteries. The blood vessels that carry blood and oxygen throughout the body become much smaller than they were. This is body of fatty deposits that collect inside of the artery. This fatty deposit is also known as plaque. This fatty deposit, or plaque, will eventually build up and clog the artery so badly that it cuts off the entire blood supply.

What is the location of osteoclasts?

User Avatar

Asked by Wiki User

Osteoclasts break down bone (osteo-=bone, -clast=breaks) and osteoblasts build bone. (-blast=builder). This osteoclasts is on the surface of the bone. Usually breaking down and building up of bone is in equilibrium.

What can you learn from histology?

User Avatar

Asked by Wiki User

Histology is the study of the cells and tissues of animals and plants. It is an essential tool of biology and medicine. Histologists are expected to know waht the gross normal and microscopic tissue looks like. This means that every different type of tissue is analyzied grossly and microscopically. Understanding these tissues in detail can mean a multitude of different concepts depending on the person. This is just the study of histology. In learning this field, the conception of how to be fully organized, trouble shoot problems, think outside the box and others is learned.

What lines much of the respiratory tract?

User Avatar

Asked by Wiki User

Pseudostratified Columnar (ciliated) epithelium lines much of the respiratory tract, but other epithelial tissues are found in the tract as well (for example, simple squamous epithelium in the alveoli of the lungs).

What is mesenchyme tissue?

User Avatar

Asked by Wiki User

First, a little background (skip down to the short answer if you already know this) because it helps to first take a couple steps backwards in order to understand. You can trace the major tissue types in the human body back to the embryo, which has three "germ layers" called endoderm (inner layer - differentiates into the "inner" coverings like epithelial linings of organs, etc), mesoderm (middle layer - differentiates into mesenchyme - connective tissue, etc.), and ectoderm (outer layer - differentiates into "outer" protective coverings like epidermis, enamel, but also forms the nervous system).

It boils down to this...ectoderm and endoderm form the "parenchymal" tissue or "parenchyma." This tissue is composed of the highly specialized cells that "do the work" in an organ. For example, hepatocytes in the liver are cells that make proteins, make cholesterol, bile salts, etc. Another example would be the parietal cells in the stomach that release hydrochloric acid, and on and on and on.

The mesoderm differentiates into the mesenchyme, which is basically "everything else." The cells in these tissues play a support function. For example, mesenchymal tissue aids parenchymal tissues by providing blood, nutrients, structural support in the form of connective tissues.

Short Answer: Mesenchyme originates from the mesoderm (loose connective tissue) and eventually differentiates into the body's connective tissues (eg supporting framework in muscle, skin, organs, the ligaments, tendons, cartilage, bone, etc.), AND it also differentiates into blood vesselsand lymphatic vessels that circulate oxygen, nutrients, enzymes/ proteins, hormones, white blood cells, they clear waste, etc. Mesenchyme tissue does the "grunt work." Therefore, these 3 categories essentially play various support roles for the specialized, "functional" (parenchymal) cells in the tissues/ organs.

What kind of stain use in histology?

User Avatar

Asked by Wiki User

It depends on what tissue you're looking at, what you want to stain, how the tissue has been stored...

Besides very specific staining, there are different types of staining. For example, immunohistochemistry, which uses antibodies to stick coloured stains to cell surface receptors. Or, chemical staining - the most common is H&E staining (haemotoxylin & eosin), so if you're just having fun in a lab and want to see general structures of cells, use this one.

What does ciliated epithelium look like?

User Avatar

Asked by Wiki User

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
