Question 1

Which term describes the ability of the nervous system to sense and control body position in space?

Accepted Answer

Proprioception

Answer

Proprioception refers to the body's ability to sense its own position, movement, and equilibrium through receptors in muscles, joints, and tendons.

Question 2

The force-velocity relationship in muscle physiology states that:

Accepted Answer

Maximum force is produced at zero velocity (isometric)

Answer

According to the force-velocity curve, peak muscle force is generated when velocity is zero (isometric contraction), and force decreases as contraction speed increases.

Question 3

Which plane of motion divides the body into left and right halves?

Accepted Answer

Sagittal plane

Answer

The sagittal plane divides the body into left and right portions; movements in this plane include flexion and extension.

Question 4

Which hormone is primarily responsible for regulating blood glucose levels by promoting cellular glucose uptake?

Accepted Answer

Insulin

Answer

Insulin, secreted by the pancreatic beta cells, signals cells to take up glucose from the bloodstream, lowering blood sugar levels.

Question 5

What does the term 'agonist' refer to in the context of muscle function?

Accepted Answer

The primary muscle responsible for a movement

Answer

An agonist (prime mover) is the muscle primarily responsible for producing a given movement, generating the majority of the force required.
