Which term describes the ability of the nervous system to sense and control body position in space?
Answer: Proprioception
Proprioception refers to the body's ability to sense its own position, movement, and equilibrium through receptors in muscles, joints, and tendons.
The force-velocity relationship in muscle physiology states that:
Answer: Maximum force is produced at zero velocity (isometric)
According to the force-velocity curve, peak muscle force is generated when velocity is zero (isometric contraction), and force decreases as contraction speed increases.
Which plane of motion divides the body into left and right halves?
Answer: Sagittal plane
The sagittal plane divides the body into left and right portions; movements in this plane include flexion and extension.
Which hormone is primarily responsible for regulating blood glucose levels by promoting cellular glucose uptake?
Answer: Insulin
Insulin, secreted by the pancreatic beta cells, signals cells to take up glucose from the bloodstream, lowering blood sugar levels.
What does the term 'agonist' refer to in the context of muscle function?
Answer: The primary muscle responsible for a movement
An agonist (prime mover) is the muscle primarily responsible for producing a given movement, generating the majority of the force required.
Which connective tissue structure connects muscle to bone?
Answer: Tendon
Tendons are dense connective tissue structures that transmit the forces generated by muscle contraction to the bones, producing movement.
