Posterior aspect of head and superior quarter of posterior surface of fibula; soleal line and middle third of medial border of tibia; and tendinous arch extending between the bony attachments: Plantarflexes ankle independent of position of knee; steadies leg on foot
In some animals, such as the rabbit, it is fused for much of its length with the gastrocnemius muscle. The soleus is a complex, multi-pennate muscle in humans, normally having a separate (posterior) aponeurosis from the gastrocnemius muscle. Most soleus muscle fibers originate from each side of the anterior aponeurosis, attached to the tibia ...
Lower Limb, Leg, Posterior compartment, Deep middle facet of lateral surface of lateral femoral condyle: posterior tibia under tibial condyles: popliteal artery: tibial nerve: medially rotates and flexes knee: 2 1 flexor hallucis longus: Lower Limb, Leg, Posterior compartment, Deep, tarsal tunnel: posterior surface of upper 1/3 of fibula
The sartorius acts as a flexor on both the hip and knee, but, due to its oblique course, also contributes to medial rotation of the leg as one of the pes anserinus muscles (with the knee flexed), and to lateral rotation of the hip joint. [23] There are four posterior thigh muscles.
The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
The plantaris muscle and a portion of its tendon run between the two muscles, which is involved in "locking" the knee from the standing position. Since the anterior compartment of the leg is lateral to the tibia, the bulge of muscle medial to the tibia on the anterior side is actually the posterior compartment. The soleus is superficial to the ...
The rabbit's hind limb (lateral view) includes muscles involved in the quadriceps and hamstrings. Rabbits have muscled hind legs that allow for maximum force, maneuverability, and acceleration that is divided into three main parts: foot, thigh, and leg. The hind limbs of a rabbit are an exaggerated feature.
The tibialis posterior muscle originates on the inner posterior border of the fibula laterally. [2] It is also attached to the interosseous membrane medially, which attaches to the tibia and fibula. [2] The tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus. [2]
