Which of the following is attached at bone joints and reduces friction?
Cartilage
Tendon
Fibrillin
Osteocytes
The Correct Answer is A
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 B
Explanation
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 B
Explanation
a. Left phrenic artery: The left phrenic artery arises from the abdominal aorta, not the ascending aorta. It supplies blood to the diaphragm.
b. Left coronary artery: The ascending aorta is the first section of the aorta, the major artery leaving the heart. It branches out to give rise to several arteries, including the left coronary artery, which supplies blood to the left side of the heart muscle.
c. Left subclavian artery: The left subclavian artery arises from the aortic arch, not directly from the ascending aorta. It supplies blood to the left arm and head.
d. Left intercostal artery: The intercostal arteries arise directly from the aorta, not specifically the ascending aorta. They supply blood to the muscles and tissues between the ribs.
