In the human body, the adductor longus is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve.
The biceps femoris is a muscle of the posterior (the back) thigh. As its name implies, it has two parts, one of which (the long head) forms part of the hamstrings muscle group.
The Extensor hallucis longus is a thin muscle, situated between the Tibialis anterior and the Extensor digitorum longus that functions to extend the big toe, dorsiflex the foot, and assists with foot inversion.
The flexor digitorum brevis lies in the middle of the sole of the foot, immediately above the central part of the plantar aponeurosis, with which it is firmly united.
The Flexor digitorum longus is situated on the tibial side of the leg. At its origin it is thin and pointed, but it gradually increases in size as it descends.
The Flexor hallucis brevis arises, by a pointed tendinous process, from the medial part of the under surface of the cuboid bone, from the contiguous portion of the third cuneiform, and from the prolongation of the tendon of the Tibialis posterior which is attached to that bone.
In humans, the gastrocnemius muscle ( /ˌɡæstrɒkˈniːmiəs/ or /ˌɡæstrəˈniːmiəs/; Latin, from Greek γαστήρ “stomach” and knēmē “leg”; meaning “stomach of leg”, referring to the bulging shape of the calf) is a very powerful superficial pennate muscle that is in the back part of the lower leg.
The gluteus maximus (also known as glutæus maximus or, collectively with the gluteus medius and minimus, the glutes) is the largest and most superficial of the three gluteal muscles.
The gluteus medius (or glutæus medius), one of the three gluteal muscles, is a broad, thick, radiating muscle, situated on the outer surface of the pelvis.
The gracilis (Latin for “slender”) is the most superficial muscle on the medial side of the thigh. It is thin and flattened, broad above, narrow and tapering below.
The Psoas major originates along the lateral surfaces of the vertebral bodies of T12 and L1-L5 and their associated intervertebral discs. The Psoas minor originates at the transverse processes of L1-L5. The Iliacus originates in the Iliac fossa of the pelvis.
The pectineus muscle (from the Latin word pecten, meaning comb) is a flat, quadrangular muscle, situated at the anterior part of the upper and medial aspect of the thigh.
The piriformis (from Latin piriformis = “pear shaped”) is a muscle in the gluteal region of the lower limb. It was first named by Spigelius, a professor from the University of Padua in the 16th century.
The quadriceps femoris (Latin for “four-headed muscle of the femur”), also called simply the quadriceps, quadriceps extensor, quads, is a large muscle group that includes the four prevailing muscles on the front of the thigh.
The tibialis posterior muscle originates on the inner posterior borders of the tibia and fibula. It is also attached to the interosseous membrane, which attaches to the tibia and fibula.
