Epithelial Tissues and connective tissue Flashcards
Epithelial Types
simple squamous, simple cuboidal, simple columnar, stratified squamous, pseudo-stratified columnar, transitional
simple squamous
smooth, flat
simple cuboidal
cube-like, large spherical nuclei
- found in kidney tubules, ducts and secretory portion of small glands and ovary surface
simple columnar
tall, oval nuclei lower third, some militated
pseudo-stratified columnar
differing levels nuclei, goblet with cilia
- all ciliated cells are columnar but not all columnar are ciliated
stratified squamous
thick multiplayer membrane
- can be keratinized or non-keratinized
stratified cuboidal
2 layer cube-like
- found in the largest ducts of sweat, mammary, and salivary glands
stratified columnar
several layers, basal-cuboidal, superficial-elongated
- found in male urethra and large ducts of some glands
transitional
surface-squamous like with done nuclei basil-cuboidal or columnar
connective tissue proper consists of…
loose connective tissue and dense connective tissue
- dense regular and irregular are structural proteins
connective tissue specialized
cartilage, bone, adipose tissue, reticular tissue, blood
3 types of cartilage
hyaline, elastic, fibrous
hyaline cartilage
weakest, most abundant type found at the end of long bones and on the ventral end of ribs, in the larynx, trachea, and bronchi
elastic cartilage
maintains shape, branching elastic fibers distinguish it from hyaline
fibrous cartilage
the strongest type; has dense collagen and little matrix
endocrine glands
release chemical substances (hormones) directly into the bloodstream or tissue of the body
exocrine glands
release chemicals substances through ducts to outside the body or onto another surface within the body
fibroblasts
makes extracellular matrix and collagen
- made of a ground substance consisting of polysaccharides, proteins, and fiber
loose connective tissue
adipose, areolar, reticular
dense connective tissue
regular dense, irregular dense, regular elastic, irregular elastic
adipocytes
aka lipocytes and fat cells are the cells that primarily compose adipose tissue
- nucleus in membrane
mast cells
type of white blood and contributes to homeostasis
apocrine glands
lose small portions of cell bodies
- larger than merocrine and connect to hair follicle
merocrine glands
secrete mucus, and serious fluids such as sweat
