Bones And Muscles Of The Lower Leg

1.

What are the names of the two bones in the lower leg
- A.
  
  Radius and Ulna
- B.
  
  Tibia and Fibula
- C.
  
  Clavicle and Scapula
- D.
  
  Femur and Humerous
Correct Answer
B. Tibia and Fibula

Explanation
The correct answer is Tibia and Fibula. The tibia and fibula are the two bones located in the lower leg. The tibia is the larger, weight-bearing bone that is located on the inside of the leg, while the fibula is the smaller bone that is located on the outside of the leg. These two bones work together to provide support and stability to the lower leg and help with movement and balance.

The bone in the upper thigh is called the Femur
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The femur is indeed the bone in the upper thigh. It is the longest and strongest bone in the human body, connecting the hip bone to the knee joint. It plays a crucial role in supporting the body's weight and facilitating movement.

Which muscle flexes the knee and foot?
- A.
  
  Peroneus
- B.
  
  Tibialis Anterior
- C.
  
  Gastrocnemius
- D.
  
  Extensor Digitorum Longus
Correct Answer
C. Gastrocnemius

Explanation
The correct answer is Gastrocnemius. The Gastrocnemius muscle is responsible for flexing the knee and foot. It is a large muscle located in the calf region of the leg. When this muscle contracts, it helps to bend the knee joint and point the foot downward, allowing for movements like walking, running, and jumping.

Which muscle extends the toes?
- A.
  
  Extensor Digitorum Longus
- B.
  
  Peroneus
- C.
  
  Soleus
- D.
  
  Tibialis Anterior
Correct Answer
A. Extensor Digitorum Longus

Explanation
The Extensor Digitorum Longus muscle is responsible for extending the toes. It is located in the front of the lower leg and runs along the shin. When this muscle contracts, it causes the toes to move upwards and away from the ground. The Peroneus muscle is responsible for eversion of the foot, the Soleus muscle is involved in plantar flexion of the foot, and the Tibialis Anterior muscle is responsible for dorsiflexion of the foot. However, none of these muscles specifically extend the toes.

The Peroneus muscle everts the foot
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The Peroneus muscle is responsible for eversion of the foot. Eversion refers to the movement of the foot where the sole turns outward away from the midline of the body. This muscle is located on the outer side of the lower leg and plays a crucial role in stabilizing the ankle joint during walking, running, and other weight-bearing activities. Therefore, the statement "The Peroneus muscle everts the foot" is true.

Which two muscles in the leg aid in flexion of the foot?
- A.
  
  Gasrocnemius
- B.
  
  Peroneus
- C.
  
  Soleus
Correct Answer(s)
A. Gasrocnemius
C. Soleus

Explanation
The gastrocnemius and soleus muscles aid in flexion of the foot. The gastrocnemius is a large calf muscle that connects to the Achilles tendon, while the soleus is a smaller muscle located beneath the gastrocnemius. Both muscles work together to help lift the heel off the ground and point the toes downward, allowing for flexion of the foot.

Which two muscles are responsible for extension of the toes?
- A.
  
  Extensor Hallucis
- B.
  
  Tibialis Anterior
- C.
  
  Extensor Digitorum Longus
Correct Answer(s)
A. Extensor Hallucis
C. Extensor Digitorum Longus

Explanation
The two muscles responsible for extension of the toes are the Extensor Hallucis and the Extensor Digitorum Longus. The Extensor Hallucis is specifically responsible for extending the big toe, while the Extensor Digitorum Longus extends the other toes. The Tibialis Anterior muscle, on the other hand, is responsible for dorsiflexion of the foot, not extension of the toes.

Achilles tendon is attached to the gastrocnemius and soleus?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The Achilles tendon is indeed attached to the gastrocnemius and soleus muscles. These two muscles are located in the calf region of the leg and play a crucial role in ankle movement. The gastrocnemius is the larger muscle and forms the upper part of the calf, while the soleus is a smaller muscle located underneath it. Both muscles merge together to form the Achilles tendon, which attaches to the heel bone. This tendon is responsible for transmitting the force generated by these muscles to the foot, allowing for movements such as walking, running, and jumping.
