Question

Quadriceps and gastrocnemius muscles lie in
A. Legs
B. Hands
C. Wrist
D. Shoulder

Answer 1

Hint: The muscles are the special tissues that help in locomotion and movement. The rhythmic contraction and relaxation of muscles causes locomotion. They always work in pairs and thus they are called antagonistic muscles, where the contraction of one muscle of the pair causes movement in one direction and contraction of another muscle of the identical pair causes movement in another direction.

Complete Step by Step Answer:
The muscles of legs can be divided into two parts:- upper leg muscles and lower leg muscles:-
The upper leg muscles consist of quadriceps, hamstrings and adductors. On the front part of the thigh four quadricep muscles are present which strengthen the knees from the bent position. On the back part of the thigh, three hamstring muscles are present which allows the knees to flex and bend. Inside the thigh, four adductor muscles are present which let the thighs bind together.
The muscles of the lower leg consist of gastrocnemius, soleus, plantaris, tibial and peroneal muscles.
Gastrocnemius are the calve muscles, soleus muscles are present below the heel to the knee, at the back of the lower leg small muscle called plantaris is present, tibialis muscles are present at back and front part of the leg and peroneus muscles are present at the front part of the lower leg.

Thus, the correct answer is option A:- legs





Note: The anterior (front) muscles of the upper leg helps in lifting, lowering your foot and extending your toes. Lateral muscles in stabilisation while walking or running. Posterior muscles help in maintaining body posture, flex and point your toes and lock and unlock your knees etc.
The anterior muscles of the lower leg help in bending and extending your knees and rotate your legs at your hips etc. The medial muscles help in moving your leg towards the centre of the body. The posterior muscles help in moving your leg from front to back etc.
