gas·troc·ne·mi·us (mus·cle)

[TA]
superficial muscle of posterior (plantar flexor) compartment of leg; origin, by two heads (lateral and medial) from the lateral and medial condyles of the femur; insertion, with soleus by tendo calcaneus into lower half of posterior surface of calcaneus; action, plantar flexion of foot; nerve supply, tibial.

gastrocnemius

(găs′trŏk-nē′mē-əs, găs′trə-)
n. pl. gastrocne·mii (-mē-ī′)
The largest, most prominent muscle of the calf of the leg, the action of which extends the foot and bends the knee.

(gas'trok-nē'mē-ŭs mŭs'ĕl)
Origin, by two heads (lateral and medial) from the lateral and medial condyles of the femur; insertion, with soleus by tendo calcaneus into lower half of posterior surface of calcaneus; action, plantar flexion of foot; nerve supply, tibial.
Synonym(s): musculus gastrocnemius [TA] , gastrocnemius.

gastrocnemius

The main muscle forming the bulge of the calf. The gastrocnemius arises by two heads from the back of the lower end of the thigh bone (femur) and is inserted, with the SOLEUS muscle, by way of the ACHILLES TENDON into the back of the heel bone (CALCANEUS). Its action is to extend the ankle joint in walking and standing on tiptoe.

gastrocnemius

the largest muscle of the calf in the human leg.

Our findings also indicated time-dependent decreases in SFI values due to sciatic nerve degeneration and gastrocnemius muscle atrophy in the axotomy groups compared to the control group.
Total RNA was extracted and isolated from gastrocnemius and soleus muscles using TRIsure reagent (Bioline, United Kingdom).
However, we observed no additional effect of electrical stimulation to the gastrocnemius muscle after BTX-A injection which was administered to the gastrocnemius and soleus muscles in this patient population.

Data for the three factors were needed to understand the muscle contraction and fatigability of the gastrocnemius muscle for each treatment concentration.
After sampling, the gastrocnemius and lower right lung specimens were immediately weighed to gain wet weight, then samples were dried at a temperature of 80[degrees]C for 48 hours, and the dry weight were measured.

Specifically, thigh IMAT or calf IMAT (standardized to CSA) and soleus IMAT or gastrocnemius IMAT (standardized to MT) were regressed against glucose, insulin, HOMA-IR, TG, TC, LDL, HDL, and TC : HDL.
In this study, 70 patients with gastrocnemius spasticity of grade 3 were recruited.
The obese animals (SED-O and RT-O) had a lower tissue weight (P<0.05) for the four muscles analyzed (brachioradial, tibialis anterior, gastrocnemius, and soleus) compared to the lean heterozygous animals (SED-L and RT -L).
