The interphalangeal joints of the foot are the joints between the phalanx bones of the toes in the feet. Since the great toe only has two phalanx bones ( proximal and distal phalanges), it only has one interphalangeal joint, which is often abbreviated as the " IP joint ".
Thus the upper arm in humans is proximal and the hand is distal. "Proximal and distal" are frequently used when describing appendages, such as fins, tentacles, and limbs. Although the direction indicated by "proximal" and "distal" is always respectively towards or away from the point of attachment, a given structure can be either proximal or ...
The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the torso. [3] A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or toe. The proximal phalanges are those that are closest to the hand or foot.
Human toes A woman's toes decorated with nail polish and henna, and wearing a metti on the second toe, for her wedding. There are normally five toes present on each human foot. Each toe consists of three phalanx bones, the proximal, middle, and distal, with the exception of the big toe (Latin: hallux). For a minority of people, the little toe ...
They are analogous to the knuckles of the hand, and are consequently known as toe knuckles in common speech. They are condyloid joints, meaning that an elliptical or rounded surface (of the metatarsal bones) comes close to a shallow cavity (of the proximal phalanges). The region of skin directly below the joints forms the ball of the foot.
The five metatarsals are dorsal convex long bones consisting of a shaft or body, a base (), and a head (). [3] The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above.
Proximal and distal, which describe a position that is closer to (proximal) or farther from (distal) the trunk of the body. [1] For example, the shoulder is proximal to the arm, and the foot is distal to the knee. Superficial and deep, which describe structures that are closer to (superficial) or farther from (deep) the surface of the body.
The foot structures are divided into segments from proximal to distal and are grouped according to similarity in shape, dimension and function. In this approach, the foot may be described in three segments: as the hindfoot, midfoot and forefoot. The hindfoot is the most proximal and posterior portion of the foot. [22]
