The Marine Corps Combat Utility Uniform has built-in slots for knee and elbow pads, but many Marines prefer to purchase their own pads. The Commandant has authorized units to purchase knee and elbow pads for uniformity. The Corps is also contracting to receive protective silk underwear in use by the British Army. While not designed for ...
These bands help stabilise the volar plates over the metacarpal heads. [2] In contrast to the volar plates of the MCP joints of the fingers, the volar plate of the thumb MCP joint is a thick structure firmly attached to the base of the proximal phalanx. It forms the bottom of a two-sided box, the sides of which are made up of the collateral ...
A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx. Each extends obliquely in a palmar direction from its proximal attachment to its distal attachment. [2]
The distal part of the palmar ligament, called the palmar plate, is 2 to 3 millimetres (0.079 to 0.118 in) thick and has a fibrocartilaginous structure. The presence of chondroitin and keratan sulfate in the dorsal and palmar plates is important in resisting compression forces against the condyles of the proximal phalanx. Together these ...
4 Dorsal interossei - Abduct the digits away from the 3rd digit (away from axial line) and are bipennate. 3 Palmar interossei - Adduct the digits towards the 3rd digit (towards the axial line) and are unipennate. This is often remembered by the mnemonic PAD-DAB, as the Palmar interosseous muscles ADduct, and the Dorsal interosseous muscles ...
The PALS grid is easily visible in this image of the US Marine Corps' Interceptor Body Armor; note the pouches attached to the system in the background (2005). The Pouch Attachment Ladder System or PALS is a grid of webbing invented and patented by United States Army Natick Soldier Research, Development and Engineering Center used to attach smaller equipment onto load-bearing platforms, such ...
The ulnar collateral ligament of the thumb runs along the ulnar side of the metacarpo-phalangeal joint of the thumb. The ulnar collateral ligament is an important stabilizer of the thumb. It is on the radial side of the wrist, but on the ulnar side of the thumb.
The metacarpophalangeal joints (MCP) are situated between the metacarpal bones and the proximal phalanges of the fingers. [1] These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges. [1]
