Biceps Femoris Muscle The Biceps Femoris is a muscle of the posterior (the back) thigh. As its name implies‚ it has two parts‚ one of which (the long head) forms part of the hamstrings muscle group. Origin and insertion It has two heads of origin; one‚ the long head‚ arises from the lower and inner impression on the back part of the tuberosity of the ischium‚ by a tendon common to it and the semitendinosus‚ and from the lower part of the sacrotuberous ligament the other‚ the short head‚

to the asymmetrical limbs movement such as running. 3) Two Ventromedial tracts: - Reticulospinal tract is involved in the movements of locomotion and posture. It also contributes to voluntary movements. In this case‚ Reticulospinal facilitates the running of the soccer players. -Vestibulospinal tract plays an important in head-eyes coordination‚ it maintains posture and balance. In dribbling soccer‚ the Vestibulospinal tract allows soccer player to maintain stability and balance on the ground while

In dorsal hemisection procedure‚ the major components of the corticospinal tract‚ the dorsal column‚ and rubrospinal tract are damaged leading to the impairment of the paw placement during walking and overground locomotion. Therefore‚ the accuracy‚ strength‚ and velocity in left and right hindlimbs are affected

pyramidal system. The pyramidal tracts controls voluntary gross motor movement. The pyramidal tract is made up of two tracts‚ the corticospinal tract and the corticonuclear tract (Rouse‚ 2015). The tracts are significant for motor movements‚ as well as‚ motor movements required for speech. The corticospinal tract originates in the cortex and travels past the pyramids located in the medulla to innervate spinal nerves through the spinal cord. The cotricospinal tract controls movement of the limbs (Rouse
