4 types of animal tissues
- epithelial tissue
- connective tissue
- muscle tissue
- nervous tissue
this type of animal tissue cover surfaces and line body cavities
epithelial tissue
functions for movement
muscle tissues
conducts electrical impulses and for sensation
nervous tissue
support function, connect tissues to another
connective tissue
specialized function of epithelial tissue
absorption & secretion
specialized function of connective tissue
transport
type of tissue that includes the mucus and serous membranes
epithelial tissue
8 types of epithelial tissue
- simple squamous
- simple cuboidal
- simple squamous (tubular arrangement)
- simple cuboidal (forming a small duct)
- simple columnar
- pseudostratified columnar (ciliated)
- transitional
- stratified squamous (moist type)
- cells are thin and flat
- spherical to polygonal (in wide view)
- centrally located nucleus
- nucleus usually centrally located
squamous
- cells are cube-like
- width and length almost similar
- centrally located nucleus
cuboidal
- column-like; taller than wide
- basally-located nucleus
columnar
lines tubules and ducts
cuboidal
lines digestive & respiratory tracts
columnar
changes shape because of regular distension
transitional
located in the urinary bladder
transitional
state of transitional cells wherein it is round, cuboidal cells
collapsed state
state of transitional cells wherein it is flat and fusiform squamous
distended (bloated); bladder has fully stretched linings
each layer of tissues is underlined by a ______
basement membrane
thin extracellular matrix for support and binding of cells in epithelial and connective tissues
basement membrane
layer of cells in simple tissues
1
layer of cells in stratified tissues
2 or more layers
stratified squamous epithelium may either be _____ or _____
- keratinized
- non-keratinized
stratified squamous epithelium may either be _____ or _____
- keratinized
- non-keratinized
stratified squamous epithelium wherein it has the protein keratin
keratinized
stratified squamous epithelium (keratinized) is mostly found in the
corneal layer of the skin epidermis
stratified squamous epithelium (non-keratinized) lines the
mucosal linings of cavities
type of tissue found in the mammary, sweat, and salivary glands
stratified cuboidal epithelium
type of tissue that lines the pharynx, conjunctiva, and male urethra
stratified columnar epithelium
resembles stratified but is actually simple
pseudostratified
in pseudostratified epithelium, nucleus are ____ & size of cells are ____
- irregularly positioned
- unequal
functions of epithelial tissue
- absorptive
- secretory / glandular
- protective
specialized for absorption
absorptive
