a) Urethra
b) Internal Urethral sphincters
c) External Urethral Sphincters
d) Bladder
View Answer
Explanation: Internal Urethral sphincters are a muscle which constricts the internal urethral orifice. It is made of smooth muscle so it is involuntary.
2. Located on the pelvic floor and is made of skeletal muscle- Internal Urethral.
a) True
b) False
View Answer
Explanation: It is External Urethral Sphincters. External Urethral Sphincters surrounds whole length of the membranous portion of the urethra. It is enclosed in urogenital diaphragm.
3. Just posterior to the symphysis pubis; hollow, collapsible sac empty=deflated balloon; full=pear shape. Name this part.
a) Bladder
b) Urters
c) External Urethral Sphincters
d) Urethra
View Answer

4. How many ureters are present?
a) 1
b) 2
c) 3

c) Stratified squamous
d) Simple cuboidal
View Answer
