EPITHELIAL TISSUE Flashcards
EPITHELIUM
● Coverings
● Lining of surfaces
B. CONNECTIVE TISSUE
● Support
● Bone, ligament, fat
C. MUSCLE TISSUE
● Movement
● Control
● Brain, nerves, spinal cord
D. NERVOUS TISSUE
flattened
Squamous -
cube-shaped/ square in shape
Cuboidal
column-like/rectangular in shape
● Columnar
Function of simple columnar (3)
○ Absorption
○ Protection
○ Secretion
Location of simple columnar
○ Lines digestive tract
○ Stomach
○ Small intestine
○ Large intestine
○ Proximal portion of anal canal
○ Gallbladder
○ Uterus and fallopian tube - presence of cilia to help
proper fertilized ovum to uterus
● Single layer of tall cells with nuclei at same level
● Often includes microvilli(bumpy extensions of apical surface,
responsible to increase absorption rate of tissues) and goblet
cells(produces mucus/lubrication as a form of protection)
C. SIMPLE COLUMNAR
● Single layer of flat cells
A. SIMPLE SQUAMOUS
Function of Simple Squamous
○ Absorption
○ Filtration

Salivary and sweat gland SS
secretion and protection
Stratified columnar location and function
CPAM
Conjunctiva
Pharynx
Anus
Male urethra
to protect and secretes waste material out of the body
Transitional or urothelium location and function
3U
Urethra
Ureters
Urinary bladder
allow tissue to expand and contract
glandular epithelium produce?
HAO
Hormones
Acids
Oil
There are two types of glandular epithelium
Exocrine glands
Endocrine glands
Example of endocrine glands and its function
TAP
Thyroid
Adrenal
Pituitary
- secretion of hormones
Example of Exocrine gland and function
SM
salivary gland
Mammary gland
produce sweat and oil glands
located on the epidermis of the skin
Keratinized stratified squamous epithelium
Example of Oral mucosa and vaginal lining
nonkeratinized stratified squamous epithelium
can be found in the surface of the trachea
PSeudostratified ciliated columnar epithelium
line in blood vessels
Endothelium
Can be found in nervous system
ependymal cells
Enumerate four factors in epithelium
- Number of cell layers
- Shape of cells
- Shape of nuclei
- Surface specialization
