The heel is an important part of the foot that allows you to stand, balance, walk, run and jump. The unmistakable shape of the heel makes it easy to locate. You may know what the heel is and all the foot problems like leg spur and calluses.
The heel, like the other components of the foot, is intricately connected by a complex network of tendons, nerves, veins, joints and bones. The most recognizable part of the bone is the heel bone, which is also called the tuber calcanei. This large leg protects the inside of the heel, provides structure for the foot and helps absorb the pressure on the foot when walking, running and jumping.
On each side of the tuber calcanei bone are two muscles, called the abductor hallucis and the abductor digit minimi. These muscles allow one to bend the big toe and little toe. The starting point for the Achilles tendon is also attached to the heel. The Achilles tendon contains a group of muscles, including the tricepts surae and the gastrocnemius. Triceps surae allows you to stretch the foot down. Another, long, narrow muscle called the light plantaris. The Achilles tendon connects the foot to the calf muscle via the ankle.
Lots of function
The function of the heel was mentioned briefly earlier, but now a more detailed description of the function of the heel will be discussed. The size, shape and location of the heel form the area in the middle of the foot, which is called the arch of the foot. The correct shape of the arch of the foot means that the force and pressure from the foot hitting the ground can be distributed evenly along the foot so that no part of the foot is damaged or torn by excessive shock. The heel also helps the foot to stabilize on uneven ground.
The underside of the feet takes a lot of force and use in a single day. Therefore, the ability to evenly distribute the weight, pressure and impact and provide stability is very important. Without the foot’s fantastic use of the heel to provide these abilities, the use of the feet would be difficult and potentially painful.
The forces exerted on the feet are distributed in five ways: three along the medial part of the foot (on the side of the big toe) and two along the lateral side (on the side of the little toe). The medial force distribution goes through the navicular and ciliary bone to the ankle bone. The lateral distribution goes over the cube and heel bone.
The combination of the ankle and heel bones that work to absorb pressure, the heel becomes the rear support point that carries the burden of the shock and pressure. The bullets on the big and small toes are the front support point that takes the other half of the main part of the impact pressure.
Under the heel, a 2 cm thick layer of subcutaneous connective tissue, equipped with built-in pressure chambers, makes the heel act as a shock absorber for the foot and a stabilizer for the sole of the foot.
The heel, like the rest of the foot, is very complex and acts as a shock absorber and stabilizer for the foot and provides protection and structure for the foot.
Injuries to the foot that affect the heel, including plantar fasciitis, can easily disrupt one’s life and ability to perform everyday tasks such as walking. A podiatrist can help diagnose and properly treat severe, acute and chronic foot problems.
