The proximal phalanx is distal to the metacarpal for each of the five fingers. It is farther from the base of the hand than the metacarpal.
The fifth metacarpal articulates proximally with the little finger. The fifth proximal phalanx meets the fifth metacarpal at the knuckle of the pinkie finger.
Each phalanx that articulates with the distal end of a metacarpal is a proximal phalanx. These phalanges are numbered one through five to distinguish them.
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.
There are four bones in the thumb. one at the top one at the bottom and one at either side.The bones in the thumb consist of: distal phalanx; proximal phalanx; metacarpal; carpal bones (carpometacarpal joint (CM).
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.
A phalanx is a toe bone. Thus a fractured proximal phalanx is a broken toe.
The thumb is made up of two phalanges (one distal phalanx and one proximal phalanx), and one metacarpal. At the "visible base" of the thumb, or where the thumb seems to enter the hand, there is a condyloid synovial joint, which involves the articulation of the proximal phalanx on the first metacarpal. The TRUE base of the thumb is where the first metacarpal articulates with the trapezium (a carpal bone of the hand). This joint is a saddle-type synovial joint.
proximal phalanx of the fourth digit
This joint is called a hinge joint
The base of the thumb, the first phalanx, makes a joint with a carpal bone called the trapezium, and the two articulate in a special joint called a saddle joint. You only have tow of these in your body, one at the base of each thumb.
Proximal means closer to the origin of the limb or finger. Medial means the inside aspect, closer to the midline. So the proximal medial aspect of the proximal phalanx is the "inside" edge of the first bone of the toe, closer to the beginning of the toe than to the end.
The finger bones are called phalanges. Each finger has three phalanges - a proximal, a middle, and a distal phalanx - except for the thumb, which only has two.
