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.

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.

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.

3. The peritoneal surface of the uterus is covered by a serosa. (Outside)2. The uterus is made up of an external layer of smooth muscle called the myometrium, and an internal layer called the endometrium.1. The endometrium has three layers: stratum compactum, stratum spongiosum (which make up the stratum functionalis) and stratum basalis. (Inside)

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.

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.

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.

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

Yes, goblet cells are found in pseudostratified ciliated columnar epithelium. Goblet cells secrete mucus that helps to protect and lubricate the respiratory tract, which is lined by pseudostratified ciliated columnar epithelium.

Conducting tissues are referred to as complex tissues because they are composed of multiple types of cells that work together to transport nutrients, water, and other substances throughout the plant. These tissues have specialized structures that allow for efficient conduction of materials, making them more intricate in their functions compared to simple tissues.

Histology is the study of microscopic anatomy at the tissue and cell level while human anatomy is the study of gross tissue and anatomy.

Histology Technicians prepare slides of body tissue for microscopic examination by freezing and cutting tissues, mounting them on slides, and staining them with special dyes to make the details visible under the microscope.

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.

Ciliated Epithelium is a modification of the Columnar epetheliun. In this columnar cells have fine, hair like cilia on their free surface. It is found in trachea and bronchi to expel any dust or food or pollutant particle out of air passage. It is also present in the fallopian tubes to move the ovum or zygote.

The articular cartilage is a covering that is found at the ends of articulating bones inside a joint. Having nerves in that are can be painful when movement is made.

Matter affects us in that we are created out of matter and everything we touch is also made of matter. Matter is everywhere in the universe and everything we use is made from some type of matter.

counterstains are selected to be contrasting color so that the target of the primary stain can easily be differentiated on a contrasting background.

This makes life easier, when, for example you need to count the number of nuclei in a smear, or number of gram positive bacteria in a mixed population.
