In human anatomy, the heel is the prominence at the posterior end of the foot. It is based on the projection of one bone, the calcaneus or heel bone, behind the articulation of the bones of the lower leg.
The compressive forces applied to the foot are distributed along five rays, three medial (side of big toe) and two lateral (side of little toe). The lateral rays stretch over the cuboid bone to the heel bone and the medial rays over the three cuneiform bones and the navicular bone to the ankle bone. Because the ankle bone is placed over the heel bone, these rays are adjacent near the toes but overriding near the heel, and together they form the arches of the foot that are optimized to distributed compressive forces across an uneven terrain. In this context the heel thus forms the posterior point of support that together with the balls of the large and little toes bear the brunt of the loads.
To distribute the compressive forces exerted on the heel during gait, and especially the stance phase when the heel contacts the ground, the sole of the foot is covered by a layer of subcutaneous connective tissue up to 2 cm thick (under the heel). This tissue has a system of pressure chambers that both acts as a shock absorber and stabilises the sole. Each of these chambers contains fibrofatty tissue covered by a layer of tough connective tissue made of collagen fibers. These septa ("walls") are firmly attached both to the plantar aponeurosis above and the sole's skin below. The sole of the foot is one of the most highly vascularized regions of the body surface, and the dense system of blood vessels further stabilize the septa.
No one hear you pray inside your life’s in vain
Can’t go on another day
The voices in your mind they penetrate your soul
Is not leaving you behind
But you can turn away
You must face your inner fears
A choice you have to make
Cause you’re the one that hear
You have the strength to do what’s right for you
You have to fight it till the end
We will support you never ever leave your side
No longer in darkness you will hide
The things you had to do was it just your inner self
Or a cry for help from you
I know you’re feeling lonely but we are always near
Wishing you were here
But you can turn away
Gotta face another day
Tomorrow you will see
Can be the day you’re free
You have the strength to do what’s right for you
You have to fight it till the end
We will support you never ever leave your side
No longer in darkness you will hide
(Cant turn away,you can’t turn away)
There is no escape at all
Gotta face another day
No you can’t turn away
You have the strength to do what’s right for you
You have to fight it till the end
We will support you never ever leave your side
