Introduction: The transverse abdominis (TrA) muscle is the deepest of the six abdominal muscles. It extends between the ribs & the pelvis, wrapping around the trunk from front to back. The fibers of the muscle run horizontally, similar to a back support belt. In this way, along with providing postural support, the transverse abdominal muscle…
Introduction: The rectus abdominis muscle also termed as the “abdominal muscle” or simply “abs”, is a paired of straight muscle.There are 2 parallel muscles which is separated by a midline band of connective tissue called the linea alba. It extends from the pubic symphysis, pubic crest & pubic tubercle inferiorly, to the xiphoid process &…
What is hamstring muscle pull? A hamstring muscle pull also called a hamstring strain occurs when one or more of these muscles gets over-stretched and leads to tear. Hamstring strains can be mild, with less pain and related symptom’s and short recovery time. Or, they can be moderate to severe and need surgery and require…
What is a Median nerve injury? It is the essential peripheral nerve in the upper limb. It passes on the medial side of the arm between the brachialis and the biceps brachii muscles. Most of the muscles in the forearm are supplied by the median nerve. For example, it controls movements like the abduction of…
What is the range of motion exercises? The range of motion exercises refers to the activity aimed at improving the movement of the joint. The motion is influenced by many structures, namely the configuration of bone surfaces within the joint, joint capsule, ligaments, tendons, and muscles acting on the joint. The range of motion exercise…
Introduction: Biceps femoris is the long muscle of the posterior aspect of the thigh. Together with the semitendinosus & semimembranosus muscles, it makes the group of muscles commonly known as the hamstrings. Biceps femoris muscle runs from the ischial tuberosity, all the way to the proximal portion of the fibula. In doing so the muscle…
Introduction: Semitendinosus is a fusiform muscle of the posterior compartment of thigh. Along with semimembranosus & long head of biceps femoris it comprises a group known as the hamstring muscles with which it shares these 3 common features: They all attach between the ischial tuberosity of pelvis & bones of the leg. They cross both…
Introduction: The semimembranosus muscle is the most medial of the 3 hamstring muscles in the thigh. It is so called because it has a flat tendon of origin. It is located at posteromedially in the thigh, deep to the semitendinosus muscle. It extends the hip joint & flexes the knee joint. The other three muscles…
What are Hamstring muscles? How are the hamstring muscles structured? The three hamstring muscles are: Biceps femoris, closest to the outside of body. The function of this hamstring is to flex the knee, extend the thigh at hip and rotate lower leg from side-to-side when knee is bent. Semimembranosus, closest to the middle of body….
