Piriformis Steroid Injection – Indication, Contraindication
Piriformis steroid injection is an injection of a long-lasting steroid into the piriformis muscle of your buttock. This muscle attaches to the side of the sacrum, which is the side, flat bone at the base of your spine just above your tailbone. Piriformis muscle injections provide diagnostic information Read More …
Gracilis Muscle – Origin, Nerve Supply, Functions
Gracilis Muscle is a long thin muscle located in the medial compartment of the thigh. It originates on the medial aspect of the ischiopubic ramus and joins together with the sartorius and semitendinosus muscle tendons to form the pes anserine, Read More …
Gracilis – Origin, Insertion, Nerve Supply, Function
Gracilis is a long thin muscle located in the medial compartment of the thigh. It originates on the medial aspect of the ischiopubic ramus and joins together with the sartorius and semitendinosus muscle tendons to form the pes anserine, which Read More …
Pectineus Muscle – Origin, Nerve Supply, Function
Pectineus Muscle is a flat, quadrangular muscle, situated at the anterior (front) part of the upper and medial (inner) aspect of the thigh. The pectineus muscle is the most anterior adductor of the hip. The muscle does adduct and laterally rotates the thigh but its primary function is hip flexion. Read More …
