Question

What are the joints present in the wrist and the bases of the fingers?

1) Radiocarpal joint and metacarpal-phalangeal joints
2) Metacarpal-phalangeal joints and interphalangeal joints
3) Radiocarpal joint and interphalangeal joints
4) Metacarpal-phalangeal joints and carpometacarpal joints

Answer 1

The joints in the wrist and the bases of the fingers are the radiocarpal joint and the metacarpophalangeal joints, corresponding to option 1.

Step-by-step explanation:

The joints present in the wrist and the bases of the fingers are the radiocarpal joint and the metacarpophalangeal joints, making the correct answer option 1) Radiocarpal joint and metacarpal-phalangeal joints. The radiocarpal joint is formed by the articulation of the scaphoid, lunate, and triquetrum bones of the proximal row of carpal bones with the distal end of the radius and a fibrocartilaginous pad spanning the radius and the styloid process of the ulna. The metacarpophalangeal joints, also known as knuckle joints, are biaxial joints where the distal ends of the metacarpal bones articulate with the proximal phalanges of the fingers enabling flexion/extension, abduction/adduction, and circumduction movements.
