What is Fingers And Toes?
Fingers and toes are two of the most important parts of the human body. They are essential for a variety of everyday activities, such as gripping items, typing on a computer keyboard and walking. Fingers and toes also play an important role in our body’s balance and coordination.The fingers are composed of three sections: the palm, the metacarpal bones (the bones in your hand) and the phalanges (the finger bones). Each finger has three phalanges: proximal (closest to your palm), middle, and distal (furthest from your palm). The thumb has two phalanges instead of three. The fingers bend at four main joints or knuckles: metacarpophalangeal joint (between the metacarpals and proximal phalanx), proximal interphalangeal joint (between the proximal and middle phalanx), distal interphalangeal joint (between distal phalanx) ,and carpometacarpa or ËœCM joint’ which joins each finger with its corresponding wrist bone. Toes are made up of four sections: toe bone, toe knuckle bone, toe nail bed bone and nail bed soft tissue. Toes have two joints that allow bending at each toe knuckle – one between each first two toes called IPJ1 (interphalangeous 1st) joint followed by IPJ2 joint between next two to last two toes called MTPJ1(metatarsophlageous 1st) joint followed by MTPJ2(metatarsophlageous 2nd) which is located right before tip of the toe called DIPJ(distalphangeous). Fingers provide us with fine motor skills that help us manipulate objects or type on a keyboard very important for our daily life. Fingers also help us grip objects like pens, pencils etc., providing great control over intricate tasks such as writing or drawing. Toes help us walk properly as they provide stability when we take steps forward or back all thanks to their flexibility. They also help us keep our balance when standing still on one foot. Moreover, both fingers and toes play an important role in sensory perception since they contain many nerve endings that allow them to detect pressure or temperature change through touch.
