Histology

Histology is a branch of anatomy that deals with the study of tissues. Tissue is a group of specialized cells and/or cell products that organized to carry out specific functions.

What is tissue hypoxia?

Tissue hypoxia (oxygen deficiency) occurs when the blood vessels in the hands, feet, and other extremities narrow in response to cold

Describe the histology of the masticatory mucosa in the oral cavity?

keratinized stratified squamous epithelium with underlying connective tissue

Where are pseudostratified ciliated columnar epithelium cells found in the body?

The Bronchial Plexus is a body location for pseudostratified ciliated columnar epithelium.

Where do histology technicians work?

The histologist does all the manual labor, while the pathologist focuses on the microscopic evaluation of the tissue. This is the case today, most large hospitals have clinical histology. These can be great places to work if you like the fast paced environments. Depending on the setting, a histologist may be required to do other jobs like microbiology, cytology, electron microscopy, molecular or genetic testing. This means a histologist could work for a hospital, college, private lab, research center of many kinds, doctors office, museum, sales, equipment repair.

What is ciliated epithelium?

It is Epithelium composed of cells bearing cilia on their free surfaces.

What can you learn from histology?

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 is tissue complementation?

tissue is a substance of an organic body or organ consisting of cells and intercellular material..

What is the study of tissues or groups of cells and their extracellular materials?

Branches of science that deals with the study of tissues include:

  • Histology - study of the microscopic anatomy of cells and tissues.
  • Pathology - study of the causes and effects of diseases that involves examination of body tissue in the laboratory for diagnostic or forensic purposes.
  • Cytology - study of the structure and function of cells with special emphasis on the cause and nature of diseases.

Histology could be defined as a study of?

It deals with the study of microscopic structure of cells.

Most histology deals with tissues, both normal and abnormal.

What lines much of the respiratory tract?

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 the function of ciliated epithelium?

Ciliated epithelium is found as the lining the respiratory tract from the nose to the trachea. This cilia secretes and propels mucous as well as sweeping dust and other irritants away from the lung.

What means histology?

History is the study of tissues

Are goblet cells found with pseudostratified ciliated columnar epithelium?

Absolutely. This type of epithelial cell is found mainly in the trachea and respiratory tract, and any system open to the outside must have mucous to keep it functioning properly for diffusion and cell health. Goblet cells make the mucous, and they are found in respiratory, digestive and reproductive system epithelium.YESYes. You have them in bronchial epithelium, probably.

What is a histology technician?

A histology technician prepares the tissue, cuts it, adheres it to slides, stains it, and cover slips the slides for diagnosis by a pathologist. Histology is the study of tissue, cytology, on the other hand is the study of cells (pap smears and fine needle aspirations), which is what cytology techs work with.

a histology technician studys cells and processes tissue for the cyto technician to read on slides. The tech is responsible for staining and cover slipping slides.?

Is tissue a collagen?

No. They are fibers found between tissues.

What are tissue amebicides?

Drugs used to treat amebiasis.Tissue amebicides are used to treat infections in the liver and other body tissues and include emetine, dehydroemetine, metronidazole, and chloroquine.

What is a tissue that lines air passages?

They are called epithelial tissues. In air passage stratified epithelium is found

'uses of microtome in histology'?

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

How do you treat granulation tissue?

Granulation tissue is a kind of tissue generated in a healing wound to both break down damaged tissue and to help prevent infection, however, sometimes growth of granulation tissue can be too robust. An excess of granulation tissue is informally known in the medical community as "proud flesh". Depending on the specifics of your case, a treating physician may apply a fine layer of silver nitrate to the excess tissue. This, in effect, cauterizes the granulation tissue (though the process is reportedly painless) and allows new healthy cell growth above that layer of flesh.

What does mesenchyme tissue do?

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.

How does transitional epithelium differ structurally from other stratified squamous epithelia?

Transitional epithelium contains cells that are flattened and cells that are cuboidal; hence the name "transitional". Stratified squamous is different from transitional epithelium since the shape of the individual cell is more hexagonal and contains flattened cells. Transitional epithelium have the capacity to stretch and flatten.

Can you give me the kinds and functions of animal tissues and plant tissues?

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

Plants and animals have tissues what is a tissue?

Tissues are made up of cells of the same type, with the same purpose. Hair, Bone, Skin, Root, Stem, Leaf etc...
