Yes - the brachium (arm) is proximal (closer to the point of origin) than the antibrachium (forearm).
The carpus is not proximal to the brachium. The carpus is actually distal to the brachium. The carpal region is the wrist.
Radial Collateral Ligament
anterbrachium is the forearm,region between elbow and the wrist while brachium is the arm,region between shoulder and the elbow
Antebrachium
The hand is immediately distal to the carpal region. In particular, the metacarpals and phalanges are distal to the carpal region.
Distal to the forearm(antebrachium) and proximal to the hand
DPB = dextral +proximal+brachium
It is called as centripetal. That is towards the centre. The reverse direction is called as centrifugal.
The upper arm, from shoulder to elbow, is the brachium. The lower arm, from elbow to wrist, is the antebrachium.
The antebrachial region is distal to the axillary region. This means that the forearm (antebrachium) is situated below the arm (axilla) when the body is in the anatomical position.
lateral bone of the antebrachium
The antebrachium is the forearm. It contains the radius on the lateral side and the ulna on the medial side.
