Sport injures Michael Fennelly assignment 1
Introduction
The following essay is the case on the hamstring muscle. The information given in the assignment brief we told that tommy is playing Gaelic football when he pulled his hamstring. The phyio has told him that it is a grade two tear. In my essay I will show the biomechanics and anatomy of the hamstring.
The hamstring muscle group is made up of three different muscles. The names of the three muscles are Biceps femoris , semitendinosus and semimembranosus . the location of each of the muscles has a different position
Biceps femoris : is postion the latrel side of the back thigh
Semitendinosus: …show more content…

Each of the different muscles have different actions
Biceps femoris: to flex the hip joint and extend the hip.
Semitendinosus: to flex the hip and to extend hip.
Semimembranosus: to flex the hip and to extend hip.
Each of the muscles different origins and insertion . As the biceps femoris has two different origin point as two different head the short and the long. The long head origin is the ischium. the short head point of origin is the linea aspera .the insertion of the biceps femoris head of the fibula and lateral condyle of tibia. The semimembranosus origin is the Ischial tuborsity the point of insertion is the medial condyle of the tibia. the semitendinous origin is on the Ischial tuberosity and the insertion point is below medial condyle of the tibia(tucker 2000)
The bone the involved with the hamstring muscle are the sacrum , the fumer the pelvies tibia fibula fig 1.2(ortho info …show more content…

Lm. meniscofemorale anterius Anterior meniscofemoral l. Connects lateral meniscus to posterior cruciate l.
Lm. popliteum obliquum oblique popliteal l. Connects medial condyle of tibia to lateral epicondyle of femur
Lm. teres femoris head of femur l. Connects from the fovea in the head of the femur to the borders of the acetabular notch
Lm. capitis fibulae posterius posterior l. of fibular head Connects head of fibula to lateral condyle of tibia

The main nerve in the upper thighs are the sciatic nerves is origins at the Sacral plexus (l4-s3 fibres) Its course start with entering the gluteal region through the greater sciatic foremen inferiorly to pisiforms descends along posterior aspect of thigh. And divides proximally to knee into tibia and common fibular perennial nerves. Its structures innervated is the motor hamstring by tibia division (except the short head of the biceps femoris. the sensory and provides articular the knee joint and branches to the
