The heel is an important part of your foot allowing you to stand, balance, walk, run and jump. The heel’s unmistakable shape makes it easy to find. You may know what the heel is and all the problems with your foot, such as bone spurs and calluses.
Like the other foot components, the heel is closely linked to a complex network of tendons, nerves, veins, joints and bones. The heel bone, also called the tuber calcanei, is the most recognizable portion of the bone. This big bone protects the inside if the heel, provides the foot structure and helps to absorb the foot pressure when walking, running and jumping.
There are two muscles on either side of the tuber calcanei bone, called the hallucis abductor and digit minimi abductor. These muscles allow the big toe and the small toe to be flexed. The Achilles tendon’s starting point is also attached to the heel. The tendon of Achilles contains a group of muscles including the surae of tricepts and gastrocnemius.The triceps surae allows one to pull down the foot. The slight plantaris was another, long, slender muscle. The tendon of Achilles connects the foot to the muscle of the calf through the ankle.
The function of the heel
The function of the heel was mentioned briefly earlier, but it will now be discussed a more detailed description of the function of the heel. The heel’s size, shape, and location shapes the foot center area, known as the arch. The arch’s proper shape allows the force and pressure from the foot that hits the ground to be distributed evenly along the foot so that no part of the foot gets damaged or worn due to excessive impact. The heel helps stabilize the foot on uneven ground as well.
The bottom of the feet in a single day will take a lot of impact and use. Therefore, it is very important to be able to evenly distribute the weight, pressure and shock and provide stability. Without the incredible use of the heel by the foot to provide these skills, it would be difficult and potentially painful to use the feet.
Distribution of forces
Five ways are distributed to the forces exerted on the feet: three on the medial part of the foot (on the side of the big toe) and two on the side (on the side of the small toe). The distribution of medial force travels to the ankle bone through the navicular and cuneiform bones. The lateral distribution goes beyond the bones of the cuboid and the heel.
The combination of ankle and heel bones that work to absorb pressure, the heel becomes the back support point that bears the impact and pressure brunt. The big and small toes balls are the front support point that takes up the other half of the impact pressure bulk.
Absorption of shocks
Under the heel, a subcutaneous connective tissue layer of 2 cm thick, equipped with built-in pressure chambers, allows the heel to act as a foot shock absorber as well as a foot sole stabiliser. Like the rest of the foot, the heel is highly complex and works as a foot shock absorber and stabilizer as well as providing foot protection and structure.
