A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue creates protective boundari...
A pathologist examines the biopsy tissue under a microscope. By noting the tissue cells' type, shape, and internal activity, in most cases apathologistcan diagnose the problem. The time it takes to get results from a biopsy can vary. During a surgery, a pathologist may read a biopsy and ...
Scars include keloids, acne, burns & hypertrophic scars. Learn how to prevent scarring & how to heal your scar tissue effectively.
The arrangement of actin and myosin filaments within each sarcomere is very regular and contributes to the formation of distinct striations (i.e. stripes) of dark A bands and light I bands when viewed under light microscope. Structure of a sarcomere in skeletal muscle A band Stria A 1/5...
The diagnosis of microscopic colitis is made when a doctor, while performing colonoscopy or flexiblesigmoidoscopy, takes biopsies (small samples of tissue) of the normal-appearing lining, and then examines the biopsies under a microscope. There are two types of microscopic: ...
when viewed under a microscope, skeletal muscle tissue has a striped or striated appearance. The striations are caused by the regular arrangement of contractile proteins (actin and myosin).Actinis a globular contractile protein that interacts withmyosinfor muscle contraction. Skeletal muscle also has ...
Students will often view prepared slides under the microscope to save time by eliminating the slide preparation process. The compound microscope can be used to view a variety of samples, some of which include: blood cells, cheek cells, parasites, bacteria, algae, tissue, and thin sections of...
Organ culture is a type of tissue culture that involves isolating an organ for in vitro growth. Here, any organ plant can be used as an explant for the culture process (shoot, root, leaf, and flower). With organ culture, or as is with their various tissue components, the method is ...
Diaphragm– It is also known as the iris. It is found under the microscope stage, and its primary role is to control the amount of light that reaches the specimen. It is an adjustable apparatus, hence controlling the light intensity and the size of the beam of light that gets to the sp...
