Question 1

What muscle supports the motion of the moving joint and helps the primary mover by stimulating the same joint motion?

Accepted Answer

Synergist

Answer

Synergists act on movable joints to assist the prime mover, or the agonist. An antagonist tries to stop the agonist from going the other way. A particular kind of synergist called a fixator retains bones so that tension can be applied to move the agonist.

Question 2

Which muscle is used when flexing the little toe?

Accepted Answer

Flexor digiti minimi brevis

Answer

The little toe is flexed by the flexor digiti minimi brevis. The great toe is extended by the extensor hallucis brevis. Both the great toe and the little toe are flexed by the flexor hallucis brevis and the abductor digiti minimi, respectively.

Question 3

These muscle groups work together effectively because they execute similar tasks.

Accepted Answer

Latissimus Dorsi and Teres Major

Answer

Adduction, extension, and medial rotation of the glenohumeral joint are all functions carried out by the latissimus dorsi and teres major. Both the major and minor pectoralis work on two distinct joints. While the gluteus medius and maximus perform similar tasks, the latter also flexes the coxal joint. The main resemblance between supraspinatus and teres minor's activities is that both keep the glenohumeral head in the glenoid cavity.

Question 4

Which of the following does the opposite of what the vastus lateralis does when it contracts on its own?

Accepted Answer

Biceps femoris short head

Answer

As opposed to the vastus lateralis, which just extends the knee, the biceps femoris short head conducts knee extension. While two of the quadriceps muscles, the rectus femoris and the vastus lateralis, are responsible for knee extension, the gracilis is responsible for adduction and medial rotation.

Question 5

What kind of stimulus does a muscle spindle respond to the most?

Accepted Answer

Rapid lengthening

Answer

One of the proprioceptors that uses muscle length to communicate with the brain about where our body is in space is the muscle spindles. When a muscle is rapidly stretched, a stretch reflex occurs. A motor neuron is then innervated by the muscle spindle to cause the stretching muscle to contract concentrically.
