In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder , thus decreasing the angle between the upper arm and the forearm .
The obturator nerve also passes through the muscle which is responsible for the sensory innervation of the skin of the medial aspect of the thigh and motor innervation of the adductor muscles of the lower extremity (external obturator, adductor longus, adductor brevis, adductor magnus, gracilis) and sometimes the pectineus. Any of these ...
The psoas minor muscle originates from the vertical fascicles inserted on the last thoracic and first lumbar vertebrae.From there, it passes down onto the medial border of the psoas major, and is inserted to the innominate line and the iliopectineal eminence.
The psoas major (/ ˈ s oʊ. ə s / or / ˈ s oʊ. æ s /; from Ancient Greek: ψόᾱ, romanized: psóā, lit. 'muscles of the loins') is a long fusiform muscle located in the lateral lumbar region between the vertebral column and the brim of the lesser pelvis.
Isolated plantaris muscle strains are rare, and ruptures normally occur in conjunction with injury to other muscles in the posterior compartment of the lower leg. [7] Symptoms of a plantaris muscle rupture may include an audible popping sound in the area during physical activity, swelling, pain in the back of the lower leg, and persistent soreness.
Shallow pain at the front of the hip may be a sign of an injury to your hip flexors (the muscles that allow you to lift your thigh). Deep pain at the front or center of the hip.
The posterior compartment is a fascial compartment bounded by fascia. It is separated from the anterior compartment by two folds of deep fascia, known as the medial intermuscular septum and the lateral intermuscular septum. [1] The muscles of the posterior compartment of the thigh are the: [2] [3]
The anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve), a branch of the common fibular nerve. The nerve contains axons from the L4, L5, and S1 spinal nerves. Blood for the compartment is supplied by the anterior tibial artery, which runs between the tibialis anterior and extensor digitorum longus muscles.
