Anatomy of the fingers.

Finger anatomy. The fingers have two long flexors located on the underside of the forearm. Finger fractures may account for up to 10 of all bone fractures. Finger injuries have the potential to slow down anyone.

A finger is a limb of the human body and a type of digit an organ of manipulation and sensation found in the hands of humans and other primates. The back of the hand shows the dorsal venous network a web of veins. Finally take the following last quiz which was created in order to test your knowledge in hand anatomy.

It specifically focuses on bones muscles including attachments innervation functions arteries veins and nerves. Normally humans have five digits the bones of which are termed phalanges on each hand although some people have more or fewer than five due to congenital disorders such as polydactyly or oligodactyly or accidental or medical amputations. The hand can be considered in four segments.

One row connects with the ends of the bones in the forearm radius and ulna. Fingers are one of the most used appendages and the most delicate so they are prone to injury. The first digit is the thumb followed by index finger middle finger ring finger and little finger or pinkie.

This is the bottom of the body of the hand. Bones muscles tendons nerves. The carpal bones are arranged in 2 interrelated rows.

The human finger is mainly a bony structure with multiple joints giving it strength and flexibility. Ligaments connect finger bones and help keep them in place. Fingers have a complex anatomy.

The deep flexor attaches to the distal phalanx and the superficial flexor attaches to the middle phalanx. They insert by tendons to the phalanges of the fingers. A digit includes the hand bones but these bones are not separated into individual appendages like a finger.

Along with the thumb and middle finger it is one of the most often used digits. Finger deformities can occur when the volar plate loosens from disease or injury. Digits that extend from the palm of the hand the fingers make it possible for humans to grip the smallest of objects.

Anatomy of the hand and wrist. The flexors allow for the actual bending of the fingers. This usually takes the form of non verbal hand gestures.

Fingers are easily injured and broken fingers are some of the most common traumatic injuries seen in an emergency room. The wrist links the hand to the arm. Instead it is contained within a single structure the hand.

Tackle it to cement and master the anatomy of the hand and wrist. The extensor tendons of the fingers begin as muscles that arise from the backside of the forearm bones. This finger has practical applications of both sensory touch and grasp but it is often used for expressive purposes as well.

Each finger has 3 phalanges bones and 3 hinged joints. The thumb has two of each. The wrist is a complex mechanical system of 8 small bones known as the carpal bones.
