[ga‚sträk′nē·mē·əs]
(anatomy)
A large muscle of the posterior aspect of the leg, arising by two heads from the posterior surfaces of the lateral and medial condyles of the femur, and inserted with the soleus muscle into the calcaneal tendon, and through this into the back of the calcaneus.

At week 12 post operation, results showed that compound action potential amplitude in gastrocnemius muscle was reduced in axotomy group compared with that in control.
After eight weeks, control and exercise groups were euthanized using isoflurane, then gastrocnemius and soleus muscles were removed, snap-frozen in liquid nitrogen, and stored in -80[degrees]C until used.
Representative histological sections of gastrocnemius muscle (A) and peritoneal adipose tissue (B) of Swiss mice of groups SS: sedentary treated with saline; SI: sedentary treated with insulin; TS: trained treated with saline; and TI: trained treated with insulin.
The isolated gastrocnemius muscle was then attached to the femur clamp with the Achilles' tendon attached to a muscle force transducer.
Generally, the number of sizeable perforators ranges from one to four, with a mean of two.[5] In a study by Wong et al.,[17] an average of 4.4 perforators was found to pierce the medial gastrocnemius muscle in each lower limb.
The gastrocnemius muscle and lung samples were harvested and immediately fixed in 10% buffered formaldehyde for 24 h and processed according to standard procedures by embedding in paraffin wax.
The prosthesis employs a quasi-passive clutched-spring knee orthosis, approximating the largely isometric behavior of the biological gastrocnemius. Two participants with unilateral transtibial amputation walk with the prosthesis on an instrumented treadmill while motion, force, electromyography, and metabolic data are collected and analyzed.
Consequently, lower limb MRI revealed that the patient had active myositis of his gastrocnemius muscles.

We also evaluated the modified Ashworth scale (mAs) of the gastrocnemius muscle [19] and the International Standards for Neurological and Functional Classification of Spinal Cord Injury (ISNCSCI) motor scores motor score as a measure of lower limb motor function.
The gastrocnemius and soleus were semiautomatically segmented and analyzed individually.
