GMS 6630 Block 1 Exam Answered & Graded
mesothelium - Correct Answer epithelium that lines body cavities and covers internal organs
endothelium - Correct Answer epithelium that lines the vascular and lymphatic systems
endocardium - Correct Answer epithelium that lines the inside of the heart
characteristics of epithelium - Correct Answer 1) cell junctions
2) polarity
3) basal lamina / basement membrane
4) avascular
forms of epithelium - Correct Answer - covers the body surfaces (forms barrier) --> interior and exterior
- forms the secretory tissue of glands and ducts
- specialized tissue functions as receptors for special senses
epithelium - Correct Answer tightly bound contiguous cells forming sheets of tissue covering body
surfaces, forming a barrier
apical layer - Correct Answer most superficial layer of cells --> faces the lumen (ie., inside of the cavity /
organ)
basal layer - Correct Answer deepest layer of epithelium, facing the basement membrane
basement membrane - Correct Answer (aka basal lamina); structural attachment site for epithelial-
based domain which is composed of extracellular matrix molecules --> product of epithelial cells
squamous - Correct Answer flat cells --> simple or stratified
keratinized epithelium - Correct Answer surface layer of dead cells --> no nuclei
pseudostratified columnar - Correct Answer epithelium where some cells do not reach the apical
surface; appears to be more than one layer, but all cells sit at the basal membrane --> ex., respiratory
system
transitional cuboidal - Correct Answer epithelium where cells start to change in shape to mark a
transition --> ex., urothelium lining of lower urinary tract
determinant factors of epithelium type - Correct Answer - apical layer of cells
- number of cellular layers
epithelioid tissue - Correct Answer epithelial tissue characterized by the absense of an apical free
surface --> ex., endocrine glands (adrenal glands, anterior pituitary, islets of Langerhans);
epithelioreticular cells (in thymus); epithelium derived tumors (epithelial ovarian carcinoma)
epithelial cells; connective tissue - Correct Answer the basal domain of _____ rests on top of the
basement membrane, while the reticular fibers of _____ lie beneath the basement membrane
mucosa - Correct Answer surface epithelium + basement membrane + lamina propria (loose CT) +
smooth muscle (sometimes) ==> lines interior of body tubes, namely the digestive, respiratory, and
genitourinary tracts
, serosa - Correct Answer epithelium (mesothelium) + basement membrane + conncetive tissue ==> lines
body cavities, namely the peritoneal, pericardial, and pleural cavities
simple squamous - Correct Answer mesothelium (lines cavity surfaces and internal organs) and
endothelium (lines circulatory system) are both examples of ____ epithelium
epidermis - Correct Answer keratinized stratified squamous epithelium --> grows continuously, but
maintains its normal thickness due to desquamination
location and function of simple cuboidal epithelium - Correct Answer - small ducts of exocrine glands
(eg., pancreas) --> absorption, conduit
- surface of ovary "germinal epithelium" --> barrier
- kidney tubules and thyroid follicles --> absorption and secretion
stratified cuboidal - Correct Answer characterized by multiple layers of cuboidal cells --> ex., large ducts
of exocrine glands
simple columnar epithelium - Correct Answer - found in many organ systems (digestive, reproductive)
- serves a sensory function (found in cornea of eye, inner ear, nose, and in the mouth and cheek)
- cilitated or non-ciliated
functions of simple columnar epithelium - Correct Answer - sensory
goblet cells - Correct Answer cells that secrete mucus, which coats and protects the surrounding surface
from damage --> viewed as large, clear circles
