Question 1

The activity of the Golgi tendon organ is involved in the inverse myotatic reflex.

Accepted Answer

Golgi tendon organs are sensory receptors located within the tendons that connect muscles to bones. When they detect tension in the muscle, they send signals to the spinal cord to inhibit the activity of the same muscle, leading to relaxation and protection against potential muscle damage. This is known as the inverse myotatic reflex.

Question 2

The basic functional unit of the neuromuscular system is the motor unit.

Accepted Answer

The motor unit is the smallest functional unit of the neuromuscular system, consisting of a motor neuron and the muscle fibers it innervates.

Question 3

Dynamic constant external resistance (DCER) strength testing measures the maximal amount of torque that can be produced at all points in the range of motion.

Accepted Answer

DCER strength testing measures the maximal amount of force or weight that can be lifted, not torque, and it does not measure force at all points in the range of motion.
