Metacarpal bones in hand

Metacarpal IV Ring finger. The relation of these bones with digits signify the bones of the five fingers.

Third Metacarpal for the middle finger.

Metacarpal bones in hand. How Many Metacarpal Bones are there in the Palm of Hand. There are five metacarpals in each hand with each bone being associated with a specific finger 1. First Metacarpal for the thumb.

Second Metacarpal for the index finger. Third Metacarpal for the middle finger. Metacarpal bones Ossa metacarpi The metacarpus is a group of five bones of the hand between the phalanges and the carpus.

Even though the metacarpal bones are small they are classified as long bones since they have structural characteristics of long bones. Each metacarpal bone consists of a shaft distal head and a wide proximal base. Metacarpal bones are situated in between the wrist and phalanges.

All the metacarpals have enlarged and mostly irregular base basis metacarpalis at the proximal end and the rounded heads caput metacarpale at the distal end. The mobility of the 1st and 5th metacarpal bone is relatively high as they are involved in the oppositionreposition motion. Carpal bones Proximal A set of eight irregularly shaped bones.

These are located in the wrist area. Metacarpals There are five metacarpals each one related to a digit. Phalanges Distal The bones of the fingers.

Each finger has three phalanges except for the thumb which has two. The second metacarpal bone has a close relationship with the Zang Fu and meridians and is the pathway of the hand Yangming large intestine meridian. Its internal-external relationship is with the hand Taiyin lung meridian and it shares its name in the meridian system with the foot Yangming stomach meridian.

There are five metacarpal bones in each hand one for each finger and the thumb. They are numbered one through five beginning with the thumb. Metacarpal lengths vary greatly from one individual to another.

Relatively speaking however the first metacarpal bone is the shortest and the most stout while the second metacarpal is the longest. It also has the largest base. Bones of the hand are of three different types as follows.

CARPEL BONES-We have 8 carpal bones which are arranged in two rows proximal and distal raw each consisting of four carpel bones. METACARPEL- these are the 5 long bones present distal to the carpal bones these. The hand bones of the metacarpal join proximally with the carpals and distally articulate with the proximal phalanges.

Metacarpal I Thumb. Metacarpal II Index finger. Metacarpal III Middle finger.

Metacarpal IV Ring finger. Metacarpal V Little finger. The palm of the hand contains five elongated metacarpal bones.

These bones lie between the carpal bones of the wrist and the bones of the fingers and thumb. The proximal end of each metacarpal bone articulates with one of the distal carpal bones. Each of these articulations is a carpometacarpal joint.

Metacarpal fractures comprise between 1844 of all hand fractures. Non-thumb metacarpals account for around 88 of all metacarpal fractures with the fifth finger most commonly involved The majority of metacarpal fractures are isolated injuries which are simple closed and stable. The metacarpal bones are the five long bones in the hand.

Any of these bones can be broken or fractured. The the 1st metacarpal under the base of the thumb is the most commonly injured. Here we explain the different hand fractures and how they are treated.

The metacarpals are long bones within the hand that are connected to the carpals or wrist bones and to the phalanges or finger bones. The metacarpals together are referred to. The metacarpals are long bones in the hand connected on one end to the wrist and the other to the finger bones or phalanges.

The tops of the metacarpal bones form the knuckles and on the palm side connective tissue covers them. The sesamoid bones in region of hand are found on the following sites. Sesamoid bone in the tendon of flexor carpi ulnaris pisiform.

Two sesamoid bones on the palmar surface of the head of first metacarpal. Sesamoid bone in the capsule of interphalangeal IP joint of thumb in 75 cases. The carpus is the anatomical term for the wrist which connects the radius and ulna of the forearm with the metacarpal bones of the hand.

It is comprised of eight individual carpal bones that are seated in two neat rows of four. The proximal row of carpal bones as seen in a lateral to medial direction on the palmar surface include. These hand bones are five in number with each one of them relating to some digit.

They articulate proximally with carpal bones in the hands while distally with the phalanges. The relation of these bones with digits signify the bones of the five fingers. Metacarpal I Thumb Metacarpal II Index finger.
