The Thigh (Anterior and Medial Compartments)
Gene L. Colborn, David B. Lause in Musculoskeletal Anatomy, 2009
The thigh can be conveniently divided into three compartments, each of which is associated with a principal nerve for motor supply of the muscles within (Fig. 10:4): Anterior chamber of the thigh (extensor compartment) Contents: quadriceps femoris muscle; sartorius muscleNerve: femoral nerveMedial chamber of the thigh (adductor compartment) Contents: adductor longus, brevis and magnus; gracilis muscle; pectineus muscleNerve: obturator nervePosterior chamber of the thigh (flexor compartment) Contents: biceps femoris muscle; semitendinosus muscle; semimembranosus muscleNerve: tibial division of sciatic nerve
The Kidney (KI)
Narda G. Robinson in Interactive Medical Acupuncture Anatomy, 2016
Semimembranosus tendon: Flexes the leg. Extends the thigh. When the knee alone is flexed, the semimembranosus muscle rotates the leg medially. When the thigh and leg are flexed, the semimembranosus extends the trunk. The main tendinous head inserts directly onto the caudomedial tibial plateau just caudal to the medial collateral ligament. The pars reflexa, the most cranial insertion, passes beneath the medial collateral ligament to insert on the tibia just distal to the medial joint line. Other insertions include the caudal aspect of the medial femoral condyle and the fascia of the popliteus muscle.
Lower Extremity Surgical Anatomy
Armstrong Milton B. in Lower extremity Trauma, 2006
This group consists only of three muscles, which are the biceps femoris, semitendinosus, and semimembranosus muscle. As a group they are referred to as the hamstring muscles. They all originate at the ischial tuberosity with the exception of the short head of the biceps femoris. The hamstrings as a group measure 15 X 45 cm2. These muscles are useful for ischial pressure sores. All the muscles of the hamstring are innervated by the same nerves. Branches of the sciatic nerve supply it with motor innervation while the postcutaneous nerve of the thigh (S1–3) supplies sensory.
Profunda femoris artery perforator flaps: a detailed anatomical study
Published in Journal of Plastic Surgery and Hand Surgery, 2020
Ahmadzadeh et al. reported an anatomical study evaluating the course and source arteries of PAP flaps. They visualized the PTR arteries of six cadavers, by injecting intra-arterial radiopaque markers and mapped skin vascularization of the PTR. They stated that the PFA supplied the most significant part of the skin vascularization of the PTR. On average, 5 ± 2 cutaneous perforators arising from branches of the PFA were seen. Of these, 65% were septocutaneous, while 35% were musculocutaneous perforators. The musculocutaneous perforators consisted of 80% biceps femoris muscle and 20% semimembranosus muscle.
