Histology Flashcards
Lines, covers, and protects other tissues and organs.
Cells tightly junked together
The presence of a cell secretion called the basement membrane
EPITHELIUM TISSUE
Cells very thin, much wider than they are thick.
Squamous Epithelium
LOCATION:
Air sacs of respiratory
Lining of blood vessels, heart, and lymphatic tubes
SIMPLE SQUAMOUS
LOCATION:
Skin
Vagina
Esophagus
Mouth
STRATIFIED SQUAMOUS
Cells cube-shaped-
* secretion and absorption.
LOCATION:
Kidney tubules
Duct and small glands
Surface of ovary
CUBOIDAL EPITHELIUM
Elongated cells, much longer than they are wide.
CULUMNAR EPITHELIUM
A single layer of cells that line the digestive tract, gallbladder, and excretory ducts of some glands. Has microvilli at surface for absorption
SIMPLE CULUMNAR
Lines the bronchi, trachea, uterine tubes and some of the uterus. Propels mucus or reproductive cells by ciliary action
PSEUDOSTRATIFIED CILIATED CULUMNAR
Characterized by the cells widely separated from each other in a matrix that is produced by the cells
CONNECTIVE TISSUE
Gel like ground with both elastic and non-elastic fibers running though the ground in many directions.
Wraps and cushions organs
Under the skin
LOSE CONNECTIVE TISSUE
Nuclei and fibers arranged in parallel rows.
Tendons and ligaments
Fibers mostly non-elastic
DENSE REGULAR CONNECTIVE TISSUE
Function as storage cells for adipose (lipids)
cells contain a large vacuole which in the live cell contains lipids.
Cell nucleus and cytoplasm are pushed out to edge of cell membrane
ADIPOSE TISSUE
Ground of matrix is gum like.
Cells are found in Lacunae within the matrix.
Fibers may be elastic or non-elastic, or a form of non-elastic called reticular(where the non-elastic fibers of very thin)
CARTILAGE
on the ends of bones
HYALINE CARTILAGE
ear cartilage
ELASTIC CARTILAGE
