Question 3

Which is one of the largest muscles in the body and the one most responsible for extending and laterally rotating the thigh

Accepted Answer

The gluteus maximus is one of the largest muscles in the body and is responsible for extending and laterally rotating the thigh. The other muscles listed also contribute to the movement of the thigh, but to a lesser extent compared to the gluteus maximus.

Question 5

The function of the biceps femoris is to

Accepted Answer

The biceps femoris muscle is located at the back of the thigh and has two heads - long head and short head. Its main function is to extend the thigh and flex the leg. Therefore, option B is the correct answer. The rest of the options are incorrect because they do not describe the primary function of the biceps femoris muscle.

Question 6

With three seconds left on the clock,Mia breaks free and scores the winning goal in her soccer game.Of the muscles listed,select the one with the primary action in extending the leg for kicking.

Accepted Answer

The quadriceps femoris is the primary muscle responsible for extending the leg for kicking, making it the best choice for this question. The biceps femoris, semimembranosus, sartorius, and tensor fasciae latae all have secondary actions in the leg but are not the primary muscle for extension.

Question 7

If you were to remove the gastrocnemius muscle,you would expose the

Accepted Answer

The gastrocnemius muscle is a superficial muscle that overlies and partially covers the soleus muscle. Therefore, if the gastrocnemius muscle were removed, the soleus muscle would be exposed. The other muscles listed are not directly covered by the gastrocnemius muscle.

Question 8

Which is not one of the hamstring muscles

Accepted Answer

The rectus femoris is not one of the hamstring muscles, it is actually a quadriceps muscle located in the front of the thigh. The other choices (Biceps femoris, Semimembranosus, Semitendinosus) are all muscles that make up the hamstrings.

Question 9

Which of the following muscles inserts on the head of the fibula

Accepted Answer

The biceps femoris muscle inserts on the head of the fibula.

Question 10

When a child raises her hand to show you she is five years old,she is using all of the following muscles except the

Accepted Answer

The flexor digitorum is not used in the action of extending the fingers to show age. It is involved in flexing the fingers, which is the opposite action of what is described. The other muscles listed are involved in extending or spreading the fingers.

Question 11

Accepted Answer

The answer of The muscles of the anterior compartment of...

Question 12

If you had all of your fingers (including the thumb)spread out wide,which muscle or group would bring fingers 2-5 together

Accepted Answer

The Palmar interossei are the muscles responsible for adducting fingers 2-5 towards the middle finger.

Question 13

The extensor hallucis longus is located in the

Accepted Answer

The extensor hallucis longus is located in the anterior compartment of the leg, along with the other muscles responsible for dorsiflexion and toe extension.

Question 14

These two muscles are known as the triceps surae and together are the most powerful plantar flexors of all of the leg muscles.

Accepted Answer

The triceps surae consists of the gastrocnemius and soleus muscles. They are the most powerful plantar flexors of all of the leg muscles, involved in activities such as standing on tiptoe, jumping, and sprinting. Tibialis posterior and popliteus are not part of the triceps surae, and while flexor digitorum longus and flexor hallucis longus are important muscles for foot movement, they are not powerful plantar flexors. Tibialis anterior and extensor digitorum longus are involved in dorsiflexion, not plantar flexion, and extensor hallucis longus and fibularis longus are not part of the triceps surae.

Question 15

Most muscles within the medial compartment of the thigh function to adduct the thigh.

Accepted Answer

This statement is true. The muscles within the medial compartment of the thigh include the adductor longus, adductor brevis, adductor magnus, gracilis, and pectineus, all of which function to adduct the thigh toward the midline of the body.

Question 16

Which muscle is the primary dorsiflexor of the foot at the ankle

Accepted Answer

The primary dorsiflexor of the foot at the ankle is the Tibialis anterior. It is located on the front of the lower leg and passes over the ankle joint to attach to the bones in the foot. It is responsible for lifting the foot and bringing the toes up toward the knee.

Question 17

Accepted Answer

The os coxae, commonly referred to as the hip bone, is the origin of most muscles that move the thigh.

Question 18

Which group of muscles forms a thick,fleshy mass at the base of the thumb

Accepted Answer

The thenar group of muscles forms a thick, fleshy mass at the base of the thumb. These muscles include the abductor pollicis brevis, flexor pollicis brevis, and opponens pollicis. The hypothenar group is located at the base of the little finger, the midpalmar group is located in the middle of the palm, the dorsal interossei group is located on the back of the hand, and the abductor digit group is not a specific group of muscles.

Question 19

If you had all of your fingers (including the thumb)spread out wide,which muscle or group would bring your thumb toward your first finger

Accepted Answer

The adductor pollicis muscle is responsible for bringing the thumb towards the first (index) finger. It is located in the palm of the hand and runs from the wrist to the base of the thumb, allowing for movement in that area. The other choices listed are involved in different movements of the fingers, but do not specifically control the movement of the thumb towards the first finger.

Question 20

Which is the longest muscle of the body

Accepted Answer

The Sartorius muscle is the longest muscle in the body, running from the hip bone down to the knee joint. It is a thin, ribbon-like muscle that helps with hip flexion, knee flexion, and leg abduction.
