The proximal phalanx of the thumb is immediately distal to the first metacarpal. In other words, the bone of the lower thumb connects to the first metcarpal.
A fracture of the distal fourth or fifth metacarpal is a broken bone in the hand, just below the ring finger or pinkie. The broken bone is in the bones that form the back of the hand. "Distal" in this case means located nearer the knuckles than the wrist.
Yes, the metacarpal bones are distal to the carpal bones in dogs. The carpal bones form the wrist joint, while the metacarpal bones are located in the paw, extending from the wrist to the toes. Thus, the metacarpals are positioned further away from the body compared to the carpals.
A "boxers" fracture generally refers to a fracture of the metacarpal bones-more commonly the fith metacarpal anywhere between mid shaft and the distal(knuckle) end of the the bone.
Each metacarpal bone consists of a base, a shaft, and a head. The base attaches to the carpal bones in the wrist, the shaft is the long middle portion of the bone, and the head connects to the phalanges in the fingers.
The arm is divided into three general regions. The first region is the upper arm. It consists of a single bone called the humerus.The second region is the lower arm. It consists of two bones, the radius and the ulna.The Radius is closest to your thumb. There aren't and bones actually connected.So it's the radius.... =] hope I helped!! :)
The capitate bone.
The fourth metacarpal bone articulates with the fourth proximal phalanx in the hand.
The third metacarpal bone of a horse is called the cannon bone or shin bone. The canon bone is the major support bone of body weight.
It is known as the thumb basal joint, also known as the carpometacarpal joint. It is a special saddle-shaped joint that is formed by the small wrist bone and the first of the three bones in the thumb.
The metacarpal bones are five in numbers and anatomically placed in the hand (in palm). Hence it makes a total of 10 metacarpal bones in two hands.The metacarpal bones can also be placed in the category of long bones of upper extremities after humerous, radius and ulna.Common characteristics are:1. The base (Carpal extremity)2. The body (The Shaft)3. The head (distal extremity)The Base or Carpal extremity articulates with the carpal bones and with the adjoining metacarpal bones.The body is the shaft of the metacarpal bone. (medial area)The head or the Distal extremity articulates with the proximal end of phalanx.So far, it is clear that metacarpal bones are attached with proximal phalanges one side and with carpal bones on the other side, hence it can be concluded that metacarpal bones make the palm.Now I think that the reader might have got his desired answer.Answered by:Ayaz AhmedLecturer, Biomedical Engineering Deptt.SIMS, Indore (MP), IndiaMob: 9425069195
Metacarpal bones
A common fracture of the fifth metacarpal bone of the hand is often referred to as the "Boxer's Fracture." The fifth metacarpal is the bone in the hand that attaches to the pinky finger.
