The primary function of feet are to serve as the foundation of the body. Our feet, a fraction of our bodies mass carries the weight of all of it. Feet also play a major role in our body's alignment and ability to balance.
Since so much is riding them perhaps we should take time to invest in the care of our 👣. Let's start by learning of their anatomy.
26 bones, 33 joints, 1,300 nerve endings, 107 ligaments, and 19 muscles
25% of the bones in the human body reside below the ankle
Three arches created by muscular contraction
medial: on the inside of the foot and runs from ourheel to our big toe
lateral: on the outside of the foot and runs from our heel to our pinkie toes
transverse: runs from the pinkie to to the big toe, across the ball of the foot
Two types of muscles
Intrinsic: both attachments begin and end in the foot itself, small muscles that control tiny
movements (example: abductor digiti minimi, the muscle that moves the little toe away from
the other toes.
Extrinsic: one attachment is in the foot and one is located outside of the foot area (example:
muscles of the calves.
Two types of nerves
Sensory: sense stimuli such as pain, smooth, rough, cold, hot.
Motor: carries impulses to central nervous system to trigger muscle contraction.
Two sizes of nerves
Small: bottom of the foot, faster signals to CNS, provide stance and upright stability
Large: when something is on the bottom of the foot it blocks response time of these nerves,
thus have to rely on larger nerves of ankle/leg to move, inability to feel the ground will result in
greater strike on the ground which means a greater impact on the joint, body in general.
