Which of the following structures is located at the neck of the bladder and surrounds the urethra in a male client?
Testes
Prostate
Rugae
Bulbourethral
The Correct Answer is B
a: Testes - The testes are located outside the body cavity within the scrotum and are responsible for producing sperm and testosterone.
b. Prostate: The prostate gland is a male reproductive organ located at the neck of the bladder and surrounds the urethra. It plays a role in the production of seminal fluid, which nourishes and transports sperm.
c: Rugae - Rugae are folds in the mucous membrane lining the urinary bladder that allow it to stretch as it fills with urine; they do not surround the urethra.
d: Bulbourethral - The bulbourethral glands (Cowper's glands) are pea-sized glands located below the prostate gland that secrete a clear fluid into the urethra during sexual arousal, but they do not surround the urethra at the neck of the bladder.

Correct Answer is A
Explanation
a. Cartilage: Cartilage is a type of connective tissue found at the ends of bones in joints. It provides a smooth, elastic surface that cushions the bones and reduces friction during movement.
b. Tendon: Tendons are tough, fibrous bands that connect muscles to bones. They do not reduce friction at joints.
c. Fibrillin: Fibrillin is a protein component of connective tissue, but it's not a specific structure like cartilage and doesn't directly reduce friction in joints.
d. Osteocytes: Osteocytes are mature bone cells. They are not located at joints and don't play a role in friction reduction.
Correct Answer is D
Explanation
a. I, IV, and VII: Cranial nerve I (Olfactory) is involved in the sense of smell, not eye movement. Cranial nerve VII (Facial) controls facial expressions, not eye movement. Cranial nerve IV (Trochlear) does control one of the extraocular muscles.
b. V and V: This is not a valid option, as it repeats the same cranial nerve. Cranial nerve V (Trigeminal) is involved in facial sensation and chewing, not eye movement.
c. IV and V: Cranial nerve IV (Trochlear) is involved in eye movement, but cranial nerve V (Trigeminal) is not.
d. III, IV, and VI: Correct. Cranial nerve III (Oculomotor), cranial nerve IV (Trochlear), and cranial nerve VI (Abducens) all control the extraocular muscles responsible for eye movements.
