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 D
Explanation
a. Prothrombin: This is a protein involved in blood clotting, not in maintaining colloid osmotic pressure.
b. Globulins: These are involved in immune responses and transportation of substances but are not the primary proteins for colloid osmotic pressure.
c. Fibrinogen: This is a clotting factor that helps in blood coagulation, not in colloid osmotic pressure.
d. Albumin: Albumin is the main plasma protein responsible for maintaining colloid osmotic pressure, which helps to keep fluid within the blood vessels.
Correct Answer is C
Explanation
a: Basal ganglia - The basal ganglia are involved in motor control and coordination but not in respiratory regulation.
b: Parietal lobe - The parietal lobe is involved in sensory processing and spatial awareness but not in respiratory regulation.
c. Medulla: The medulla oblongata, specifically the respiratory center within it, is responsible for the involuntary control of respiration, including setting the basic rhythm of breathing and responding to changes in blood pH and oxygen levels.
d: Hypothalamus - The hypothalamus regulates various physiological processes, including temperature regulation and hormone secretion, but not respiration.
