Introduction The iliacus and psoas major muscles combine to form the iliopsoas, a large complex muscle of the inner hip. Other muscles of the inner hip besides the iliopsoas are the quadratus femoris, piriformis, superior and inferior gemellus, obturator externus, and psoas minor. The psoas major section of the iliopsoas originates from the twelfth thoracic…
Introduction the popliteus muscle is a major stabilizer of the knee jointThe popliteus is a small, thin, flat, triangular-shaped musculotendinous complex muscle that forms the floor of the popliteal fossa. It belongs to the deep posterior leg muscles, along with the tibialis posterior, flexor digitorum longus, and flexor hallucis longus muscles. It is a deep…
Introduction The fibular/peroneal muscles are the two muscles of the lateral compartment of the leg. These muscles are the fibularis longus and fibularis brevis. The peroneal muscles originate from the fibula and are inserted onto the plantar surfaces of certain tarsal and metatarsal bones. These muscles play an important role in the movements of the…
Introduction The hip adductors are a group of muscles located in the medial compartment of the thigh. These muscles include the adductor longus, adductor brevis, adductor Magnus, gracilis, and pectineus. Due to their position, the hip adductors shape the surface anatomy of the medial side thigh. More specifically, these muscles extend from the anteroinferior external…
Muscles Of Back Of Thigh- Introduction: Posterior thigh muscles (hamstrings)The hamstring muscles are a group of three long muscles which is located in the posterior compartment of the thigh, shaping up the surface anatomy of this region. The Hamstring group of muscles includes the biceps femoris, semitendinosus, and semimembranosus muscles. The hamstrings muscles are closely…
Introduction: Anatomically, the leg is defined as the part of the lower limb below the knee. It consists of three-compartment, posterior, anterior, and lateral compartments. In accordance, the muscles of the leg are organized into three different groups:The Anterior group(dorsiflexor group), contains the tibialis anterior, extensor digitorum longus, fibularis tertius, and extensor hallucis longus muscles….
Introduction : The four 4 sub-components are: Rectus femoris : Origin : The rectus femoris is a fusiform muscle that contains two heads. It originates from two sites on the ilium; the anterior inferior iliac spine (AIIS)(straight head) and supraacetabular groove (reflected head). The two heads unite into a common muscle belly that courses down…
Semitendinosus Muscle Anatomy Semitendinosus muscle is one of 3 Hamstring group muscles that are located backside of the thigh and is responsible for the flexion of the knee. Other Hamstring muscles are the biceps femoris and semimembranosus. All three muscles (semimembranosus, semitendinosus, and biceps femoris) are part of the hamstring muscles. Semitendinosus and Semimembranosus are…
Flexor Digiti Minimi Brevis Muscle Anatomy One of the hand’s short intrinsic muscles is the flexor digiti minimi brevis. It is a member of the same muscle group as the opponens digiti minimi and abductor digiti minimi, which is known as the hypothenar muscles. The hypothenar eminence, an elevation above the base of the little…
Adductor Hallucis Muscle Anatomy Adductor hallucis muscle arises by two heads—oblique and transverse and is responsible for adducting the big toe. Additionally, there are four horizontal layers of foot muscles, ranging from superficial to deep. Adductor hallucis, flexor hallucis brevis, and flexor digiti minimi brevis make up the third layer of plantar foot muscles in…
