What type of sensory information do muscle spindles transmit? Choose the correct option.

A. Changes in angle of joint

B. Changes in muscle length

C. Changes in muscle strength

D. Changes in muscle tension

Which of the following describes the function and location of Golgi tendon organs? Choose the correct answer.

A. Monitor muscle tension, situated in series with muscle fibers

B. Monitor muscle length, situated in series with muscle fibers

C. Monitor muscle length, situated in parallel with muscle fibers

D. Monitor muscle tension, situated in parallel with muscle fibers

True or false? An alpha motor neuron and all the muscle fibers innervated by it make up the elementary component of motor control called the motor unit.

Select one:

True

False

Muscle spindles transmit information about changes in muscle length, while Golgi tendon organs monitor muscle tension. The correct choices are B for muscle spindles and A for Golgi tendon organs. The statement about alpha motor neurons forming a motor unit is true.

Muscle spindles are sensory receptors embedded within the belly of muscles. They are sensitive to changes in muscle length and the rate of that change. When a muscle stretches, muscle spindles get stretched too, which sends signals to the central nervous system about the length of the muscle and helps maintain posture and balance by initiating the stretch reflex.
