Biceps femoris: originates on the ischiatic tuberosity and inserts on the patellar ligament. It acts to extend the hip, stifle and hock. It is innervated by the sciatic nerve. Semitendinosus: originates on the ischiatic tuberosity and inserts on the tibia. It acts to extend the hip, flex the stifle and extend the hock.
The biceps femoris (/ ˈ b aɪ s ɛ p s ˈ f ɛ m ər ɪ s /) is a muscle of the thigh located to the posterior, or back. As its name implies, it consists of two heads; the long head is considered part of the hamstring muscle group, while the short head is sometimes excluded from this characterization, as it only causes knee flexion (but not hip extension) [1] and is activated by a separate ...
It is a remnant of part of biceps femoris muscle. The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which it is partly blended), to the lower transverse sacral tubercles and the lateral margins of the lower sacrum and upper coccyx.
The caudofemoralis originates from the transverse processes of the second, third and fourth caudal vertebrae.The caudodistal portion of the muscle in mammals lies deep to the proximocranial portion of the Biceps femoris; near the middle of the thigh, the caudofemoralis gives rise to a long, thin, and narrow tendon that passes distally to the knee joint and inserts into the fascia lata that is ...
The semitendinosus, remarkable for the great length of its tendon of insertion, is situated at the posterior and medial aspect of the thigh.. It arises from the lower and medial impression on the upper part of the tuberosity of the ischium, by a tendon common to it and the long head of the biceps femoris; it also arises from an aponeurosis which connects the adjacent surfaces of the two ...
biceps femoris muscle, which consists of a short head and a long head. semitendinosus muscle; semimembranosus muscle; These muscles (or their tendons) apart from the short head of the biceps femoris, are commonly known as the hamstrings. The depression at the back of the knee, or kneepit is the popliteal fossa, colloquially called the ham. The ...
There is a latency of around 18 ms between stretch of the patellar tendon and the beginning of contraction of the quadriceps femoris muscle. [5] This is a reflex of proprioception which helps maintain posture and balance , allowing to keep one's balance with little effort or conscious thought.
It arises above and medial to the biceps femoris muscle and semitendinosus muscle. The tendon of origin expands into an aponeurosis , which covers the upper part of the anterior surface of the muscle; from this aponeurosis, muscular fibers arise, and converge to another aponeurosis which covers the lower part of the posterior surface of the ...
