Why does the gastrocnemius muscle contract after stimulating the sciatic nerve?
Wiki User
∙ 10y ago
The gastrocnemius is stimulated by a branch of the sciatic nerve called the tibial nerve. This causes contraction and produces plantar flexion of the foot. When a person stands on their "tippy toes" that is plantar flexion. This is a function of this nerve.

What is effector muscle for calcaneal reflex action?
gastrocnemius
What other name for calf in the human body?
The anatomical area of the calf is called the sural. Also the calf is made of muscle: the gastrocnemius and the underling soleus.
What is the opposite muscle to the tibialis anterior?
The gastrocnemius (plantar flexes the foot) is the muscle which is opposite of the tibialis anterior dorsiflexor of the foot).
What Major function is to contract?
muscle tissue
What is the effector of the Achilles reflex?
gastrocnemius muscle
What muscle would you have your client contract if they get a cramp in their gastrocnemius?
gastrocnnemius
What does the contraction of the gastrocnemius muscle usually result in?
type of contraction of gastrocnemius muscle?
What is the synergist muscle for the gastrocnemius?
Gastrocnemius
What is the receptor of the Achilles reflex?
Hit tendon nociceptors in tendo-achilles. It goes to the CNS by sciatic nerve, then it goes to interneurons in spinal cords S1-S2. Then it goes to Alfa motor n, tibial nerve from sciatic nerve to lead to the gastrocnemius muscle.
Is the soleus muscle superficial to the gastrocnemius?
The answer would be false. The soleus muscle is superficial to the tibia NOT the gastrocnemius.
What muscle is located directly beneath the gastrocnemius and has similar functions to gastrocnemius?
Soleus is the muscle that is located directly beneath the gastrocnemius and has similar functions to the gastrocnemius. The hamstrings muscles are a two joint muscle that acts at the knee and hip.
Does the gastrocnemius muscle form the cup of the shoulder?
No, the gastrocnemius muscle forms the belly of the calf in the lower leg.
What muscle is superior to the soleus muscle?
gastrocnemius
What knee muscle have reverse actions?
Gastrocnemius muscle
To bend the ankle which muscle must contract?
The ankle bends two ways, anterior (up) and posterior (down), so it depends. The bend the ankle down (point the toe), the gastrocnemius muscle (calf) must contract. To bend the ankle up (lift the toe) the tibialis anterior muscle must contract.
What is the gastronemius?
The gastrocnemius muscle is located with the soleus in the posterior (back) compartment of the leg. It is associated with the "bulge" in the calf muscle.
