The anatomy of the foot is a tremendously complex one. Plantar Flexion as defined by O’Toole (2013) “A toe down motion of the foot at the ankle. It is measured in the degrees from the 0 degree position of the foot at rest on the ground, with the body in a standing position.” Plantar flexion is a movement that is used every day, from climbing the stairs to applying the foot the pedal while driving (Contributor, 2015).
Motion defined by (Lippert,2011). ‘As the process of moving joints, limbs or specific sections of the body’. Motion in relation to the plantar flex is achieved by the calf muscles, which are called the superficial muscles. These muscles share a tendon called the Achilles tendon otherwise known as the Calcaneal. This tendon is an important one, as it attaches the calf muscles to the heel bone, which enables the foot to preform a plantar flex (O’toole, 2013). Most of the motion is caused by the superficial muscles (Dale, 2015) .These muscles are the gastrocnemius and just behind it is the soleus; the tendons of these muscles insert into the calcaneal bone(O’toole , 2013). Superficial muscles insert into the calcaneal bone of the ankle. Superficial and deep muscles work together in order to achieve a plantar flex at the ankle joint (Tortora and Derrickson, 2014). …show more content…
In order for a skeletal muscle to contract, it has to first be stimulated by a nerve (Harrison, 2006). The muscles contract by a process known as the sliding filament theory. The structures involved in this process are myofibril, sarcomere, actin and myosin (Jackson,
