New cards

radioulnar joints and ligaments

  1. annular ligament

  2. interosseous membrane

  3. articular discs


4
New cards

annular ligament

holds head of radius in articulation with ulna at radial notch

<p>holds head of radius in articulation with ulna at radial notch</p>
5
New cards

interosseous membrane

connects radius and ulna along their diaphysis

  • forms radioulnar syndesmosis joint (fibrous, slightly moveable)

New cards
<p>transverse carpal ligament</p>

transverse carpal ligament

a large, fibrous ligament that stretches over the palmar side of the wrist

  • connects scaphoid and trapezium laterally with pisiform and hamate medially

  • forms tunnel with carpals through which tendons pass

New cards
<p>bones of hand</p>

bones of hand

metacarpals → phalanges (proximal → middle → distal)

17
New cards

carpometacarpal joints

between carpals and metacarpals

18
New cards

first carpometacarpal (CMC) joint

thumb → saddle joint, separate synovial cavity

  • enables opposition


19
New cards

second and fifth CMC

fingers → plane joints, share synovial cavity

  • second and third are nearly immobile (rigid platform) → 4th and 5th moderately mobile


20
New cards

metacarpophalangeal joints

between metacarpals and proximal phalanx

  • condyloid joints (flexion/extension, abduction/adduction)

  • supported by deep transverse metacarpal ligament, palmar plates, and collateral ligaments


21
New cards

interphalangeal joints

between adjacent phalanges

  • hinge joints (flexion and extensions)

  • supported by palmar plates and collateral ligaments

  • only one in 1st digit
