Sole (foot)

Like those of the palm, the sweat pores of the sole lack sebaceous glands.

In humans, they occur in the greatest number on the face and scalp, but also on all parts of the skin except the palms of the hands and soles of the feet.

The subcutaneous tissue in the sole has adapted to deal with the high local compressive forces on the heel and the ball (between the toes and the arch) by developing a system of "pressure chambers."

The ball of the foot is the padded portion of the sole between the toes and the arch, underneath the heads of the metatarsal bones.

The subcutaneous tissue in the sole has adapted to deal with the high local compressive forces on the heel and the ball (between the toes and the arch) by developing a system of "pressure chambers."

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).

The arches might collapse later in life, resulting in flat feet.

Flat feet (also called pes planus or fallen arches) is a postural deformity in which the arches of the foot collapse, with the entire sole of the foot coming into complete or near-complete contact with the ground.

The glabrous skin on the sole of the foot lacks the hair and pigmentation found elsewhere on the body, and it has a high concentration of sweat pores.

On the human body, glabrous skin is found on the ventral portion of the fingers, palms, soles of feet and lips, which are all parts of the body most closely associated with interacting with the world around us, as are the labia minora and glans penis.

In humans the sole of the foot is anatomically referred to as the plantar aspect.

Volar can also be used to refer to the underside of the palm or sole, which are themselves also sometimes used to describe location as palmar and plantar.

In the first layer, the flexor digitorum brevis is the large central muscle located immediately above the plantar aponeurosis.

Its deep surface is separated from the lateral plantar vessels and nerves by a thin layer of fascia.

The sole is the bottom of the foot.

Medically, the soles are the site of the plantar reflex, the testing of which can be painful due to the sole's sensitivity.

The [[Human anatomical terms#Near or away from the vertical longitudinal center of the body|lateral]] side of the sole of the foot is rubbed with a blunt instrument or device so as not to cause pain, discomfort, or injury to the skin; the instrument is run from the heel along a curve to the toes (metatarsal pads).

The considerably smaller flexor digiti minimi brevis on the lateral side can be mistaken for one of the interossei.

The beating of the soles of a person's bare feet (foot whipping or bastinado) has served as a traditional means of corporal punishment and discipline in various civilizations to this day and is also used as a method of torture.

The uncovered soles of the feet need to be placed in an exposed position.

It flexes the second to fifth toes and is flanked by abductor hallucis and abductor digiti minimi.

The superficial and deep branches of the lateral plantar nerve from the tibial nerve provide sensory innervation to the skin of the lateral side of the sole, to the fifth and half the fourth toes, and the nail bed of these toes.

The plantar digital nerves from the medial plantar nerve provide sensory innervation to the skin of the plantar aspect of the toes, except the medial part of the big toe and the lateral part of the little toe and the motor innervation of the first lumbrical.

It is crossed by a set of creases that form during the early stages of embryonic development.

The subcutaneous tissue in the sole has adapted to deal with the high local compressive forces on the heel and the ball (between the toes and the arch) by developing a system of "pressure chambers."

Each chamber is composed of internal fibrofatty tissue covered by external collagen connective tissue.

The septa (internal walls) of these chambers are permeated by numerous blood vessels, making the sole one of the most vascularized, or blood-enriched, regions in the human body.
