Question

The 5 long, thin bones that form the palm of the hand are the:

Options:
Option 1: Metacarpals
Option 2: Phalanges
Option 3: Carpals
Option 4: Radius

Answer 1

The 5 long, thin bones that form the palm of the hand are known as the metacarpals, which articulate with the carpal bones and the phalanges at the knuckles. So, the correct answer is option 1.

Step-by-step explanation:

The 5 long, thin bones that form the palm of the hand are the metacarpals. These are the bones that lie between the carpal bones of the wrist and the bones of the fingers and thumb. The metacarpal bones are connected to the phalanges of each digit at the metacarpophalangeal joints, commonly known as the knuckles. Each metacarpal bone articulates with one of the distal carpal bones, forming the carpometacarpal joints. The metacarpals are numbered from 1 to 5, starting on the lateral side with the thumb, making them easy to identify in the structure of the hand.

So, the correct answer is option 1.
