Which muscle is responsible for extending the big toe?

Extensor digitorum longus

Explanation

Extensor digitorum longus, located in the shin, extends the toes and dorsiflexes the foot at the ankle joint.

Which muscle is responsible for flexing the toes?

Flexor digitorum longus

Explanation

Flexor digitorum longus, located in the lower leg, is responsible for flexing the toes and plantar flexion of the foot.

Which muscle is responsible for plantar flexion of the foot?

Gastrocnemius

Explanation

Gastrocnemius is a calf muscle that plays a primary role in plantar flexion of the foot, pointing the toes downward.

Which muscle group is commonly referred to as the 'calf muscles'?

Gastrocnemius and soleus

Explanation

The 'calf muscles' typically refer to the Gastrocnemius and Soleus muscles, which are both located in the calf region and contribute to various leg movements.

#10

Which muscle is located on the posterior aspect of the thigh and is responsible for extending the thigh at the hip joint?

Gluteus maximus

Explanation

Gluteus maximus, the largest buttock muscle, extends the thigh at the hip joint and is situated on the posterior aspect of the thigh.

#11

Which muscle is responsible for inversion of the foot at the ankle joint?

Tibialis anterior

Explanation

Tibialis anterior, located in the shin, is responsible for dorsiflexion and inversion of the foot at the ankle joint.

#12

Which muscle acts to stabilize the hip joint and is commonly referred to as the 'hip flexor'?

Iliopsoas

Explanation

Iliopsoas, a composite muscle, is commonly known as the 'hip flexor' and contributes to stabilizing the hip joint.

#13

Which muscle is located on the medial aspect of the thigh and is responsible for adduction of the thigh at the hip joint?

Gracilis

Explanation

Gracilis, situated on the inner thigh, is responsible for adduction of the thigh at the hip joint, moving it toward the body's midline.

#14

Which muscle group is responsible for dorsiflexion of the foot?

Tibialis anterior

Explanation

Tibialis anterior, located in the shin, is a key muscle group responsible for dorsiflexion of the foot, lifting the toes toward the shin.

#15

Which muscle acts to flex the hip joint and is commonly known as the 'tailor's muscle'?

Sartorius

Explanation

Sartorius, often called the 'tailor's muscle,' is located in the thigh and plays a key role in flexing the hip joint and crossing the legs.

#16

Which muscle is responsible for flexion of the toes?

Flexor hallucis longus

Explanation

Flexor hallucis longus, situated in the lower leg, is responsible for flexing the big toe at the metatarsophalangeal joint.

#17

Which muscle is the largest and strongest muscle in the human body?

Gluteus maximus

Explanation

Gluteus maximus, located in the buttocks, is the largest and strongest muscle in the human body, primarily responsible for hip extension.

#18

Which muscle is responsible for rotation of the thigh laterally?

Piriformis

Explanation

Piriformis, a deep hip muscle, is responsible for rotating the thigh laterally, turning it outward.

#19

Which muscle is responsible for stabilizing the knee joint during standing and walking?

Popliteus

Explanation

Popliteus, located behind the knee joint, plays a crucial role in stabilizing the knee during standing and walking.
