L6 Epithelium Flashcards
From which embryological origins does epithelium arise?
A) Mesoderm
B) Ectoderm
C) Endoderm
D) All of the above
D) All of the above
An epithelial basement membrane consists of __1__ lamina and __2__ lamina
1) basal lamina
2) reticular lamina
Kidney tubules are lined by __?__ epithelium
Simple cuboidal
Alveoli are lined by __?__ epithelium
Simple squamous
The small intestine is lined by __?__ epithelium
Simple columnar
The oesophagus is lined by __?__ epithelium
Stratified squamous
Where would you find keratinised stratified squamous epithelium?
Only found in skin
The trachea is lined by __?__ epithelium
Pseudostratified columnar
Sweat gland ducts are lined by __?__ epithelium
Stratified cuboidal
Salivary gland ducts are lined by __?__ epithelium
Stratified columnar
Exocrine glands secrete into __?__
ducts that open into lumen of organ or onto the skin
Endocrine glands secrete into __?__
empty tissue spaces, eventually hormones enter the blood stream (no ducts)
What is the difference between merocrine, apocrine, and holocrine secretion?
Merocrine: secretion passes from cells without damaging the cell or cell membrane.
Apocrine: Apical surfase of cells pinched off to release pockets of the hormone.
Holocrine: Whole cell dies to release secretion
Epithelial membranes contain epithelium and __?__
an underlying connective tissue
Synovial membranes contain only __1__ tissues, and line the cavities of __2__
1) connective
2) synovial joints
Serous membranes are generally simple __1__ epithelium resting on a thin layer of __2__. Serosa is found lining __3__.
1) squamous
2) loose connective tissue
3) closed body cavities
Cavities open to the external environment are generally lined by __1__ membranes. In the digestive tract the mucosa has [microvilli/cilia], and in the respiratory tracts the mucosa has [microvilli/cilia]
1) mucous
2) microvilli
3) cilia
Serous membranes have two layers: the __1__ layer (attaches to the body wall around the organ) and the __2__ layer (attaches to the organ it surrounds).
1) parietal
2) visceral
The pleura (surrounding the __1__), __2__ (surrounding the heart) and peritoneum (in the abdomen) are all prominent examples of __3__ membranes.
1) lungs
2) pericardium
3) serous
Between the two layers of serous membrane is a fluid called __?__ fluid.
serous
Synovial membranes line the cavities of freely movable joints, and contain on __?__ tissues.
connective
