Some languages have different names for hand and foot digits (English: respectively "finger" and "toe", German: "Finger" and "Zeh", French: "doigt" and "orteil").. In other languages, e.g. Arabic, Russian, Polish, Spanish, Portuguese, Italian, Czech, Tagalog, Turkish, Bulgarian, and Persian, there are no specific one-word names for fingers and toes; these are called "digit of the hand" or ...
Anatomical terms of bone [ edit on Wikidata ] In human anatomy , the metacarpal bones or metacarpus , also known as the "palm bones", are the appendicular bones that form the intermediate part of the hand between the phalanges ( fingers ) and the carpal bones ( wrist bones ), which articulate with the forearm .
Linburg–Comstock variation is an occasional tendinous connection between the flexor pollicis longus and the flexor digitorum profundus of the index, the middle finger or both. It is found in around 21% of the population. [1] It is an anatomical variation in humans, which may be viewed as a pathology if it causes symptoms. It was recognised as ...
The primary function of the extensors is to straighten out the digits. The thumb has two extensors in the forearm; the tendons of these form the anatomical snuff box. Also, the index finger and the little finger have an extra extensor, used for instance for pointing. The extensors are situated within six separate compartments.
Some anatomists [5] restrict opposition to when the thumb is approximated to the fifth finger (little finger) and refer to other approximations between the thumb and other fingers as apposition. To anatomists, this makes sense as two intrinsic hand muscles are named for this specific movement (the opponens pollicis and opponens digiti minimi ...
The hamate is found within the distal row of carpal bones, and abuts the metacarpals of the little finger and ring finger. [4]: 708–709 Adjacent to the hamate on the ulnar side, and slightly above it, is the pisiform bone. Adjacent on the radial side is the capitate, and proximal is the lunate bone. [4]: 708–709
Some fibers insert into the finger's dorsal aponeurosis, which is why the muscle acts similar to a dorsal interosseus muscle. [ 2 ] Additionally, the ulnar-most portion of the tendon inserts into the little finger's digital cord, and the muscle thus forms part of a structure that flexes the metacarpophalangeal joint and extends the ...
The dorsal surface of the body is divided by an oblique ridge, which extends from near the ulnar side of the base to the radial side of the head. The lateral part of this surface serves for the attachment of the fourth interosseus dorsalis; the medial part is smooth, triangular, and covered by the extensor tendons of the little finger.
