Nerve supply. Both heads of the gastrocnemius is supplied by the tibial nerve (S1 and 2). Cutaneous supply is mainly provided by L4, 5 and S2. Function. The gastrocnemius with the soleus, is the main plantarflexor of the ankle joint. The muscle is also a powerful knee flexor.

To follow it, we’ll remove two muscles which it supplies: gastrocnemius, and soleus. The tibial nerve follows the same course as the posterior tibial artery. The nerve passes beneath the flexor retinaculum just behind the artery. Beneath the flexor retinaculum, the tibial nerve divides, into the medial plantar nerve, and the lateral plantar nerve.

It is a bipennate muscle, meaning it has two rows of muscle fibres, facing in opposite directions with a central tendon, resembling a feather. Upper motor neurons synapse with lower motor neurons at the anterior horn of the spinal cord in the sacral plexus (formed from the anterior rami of spinal nerves L4, L5, S1–4). The lower motor neuron fibers continue down the sciatic nerve and then diverge into the tibial and common fibular nerves. To follow it, we’ll remove two muscles which it supplies: gastrocnemius, and soleus. The tibial nerve follows the same course as the posterior tibial artery. The nerve passes beneath the flexor retinaculum just behind the artery. Beneath the flexor retinaculum, the tibial nerve divides, into the medial plantar nerve, and the lateral plantar nerve.

Indeling: Hoort bij: dorsale onderbeenspieren Functie: flexie in het kniegewricht, plantairflexie en supinatie van de voet in het enkelgewricht Function Motor. At the popliteal fossa, branches of the tibial nerve supply medial and lateral heads of gastrocnemius, soleus, plantaris and popliteus muscles.

The superficial portion (the gastrocnemius) gives off 2 heads attaching to the base of the femur directly above the knee. The deep (profundus) mass of muscle (the soleus) forms the remaining head which attaches to the superior posterior area of the tibia. The triceps surae is innervated by the tibial nerve, specifically, nerve roots L5–S2.

Innervation is by the tibial nerve. Vascular supply to the gastrocnemius muscles is by stout short branches from the adjacent popliteal artery and vein; detailed studies of the venous vascular configuration has demonstrated 4 main patterns, with 2 to 12 branches per muscle head 3. The proximal tendons of the gastrocnemius muscles originate at the medial and lateral femoral epicondylar regions; the medial tendon is thicker along its medial margin and closer to midline contain small amounts of A clip from Physiology lab. We ran a current of moderate tetanizing strength through the sciatic nerve of a frog's leg.

It moves from its two heads just over the knee to the heel, a two joint muscle. The common peroneal nerve gives off the lateral sural cutaneous nerve proximal to the origin of the gastrocnemius muscle and this nerve communicates with the medial sural nerve by a short branch. The tibial nerve gives off the medial and lateral sural motor nerves (the medial branch being usually 1–2 cm proximal to the lateral one) in the distal portion of the proximal third of the popliteal fossa. For the MGR, the greater saphenous vein (5.3-17.6 mm) and saphenous nerve (5.1-18.6 mm) were at greater risk.

Both medial and lateral heads of gastrocnemius are supplied by the lateral and medial sural arteries , which are direct branches of the popliteal artery . The gastrocnemius muscle is prone to spasms, which are painful, involuntary contractions of the muscle that may last several minutes. A severe ankle dorsiflexion force may result in an Medial Gastrocnemius Strain (MGS) injury of the muscle, commonly referred to as a "torn" or "strained" calf muscle, which is acutely painful and disabling. Contraction of the medial head of the gastrocnemius rotates the leg medially (internal rotation of the leg), while the activation of the lateral head rotates the leg laterally (external rotation of the leg).

The gastrocnemius (also gastrocnemius muscle, latin: musculus gastrocnemius) is a superficial muscle of the posterior group of the lower leg muscles. It consists of two heads - medial and lateral. Both heads of gastrocnemius join with the tendon of soleus and insert into the calcaneal tuberosity. The gastrocnemius muscle is a muscle located on the back portion of the lower leg, being one of the two major muscles that make up the calf. The other major calf muscle, the soleus muscle, is a Gastrocnemius muscle. The gastrocnemius muscle is one of the calf muscles (triceps surae) in the superficial posterior compartment of the leg which sits superficial to the much larger soleus muscle.
