Which of the following are bones of the wrist?
A
Radius
B
Carpals
C
Metacarpals
D
Phalanges
Verified step by step guidance1
Step 1: Begin by understanding the anatomy of the wrist. The wrist is composed of a group of small bones collectively known as the carpals. These bones form the connection between the forearm and the hand.
Step 2: Differentiate between the options provided. The radius is a forearm bone, not part of the wrist. Metacarpals are bones of the hand, located between the carpals and the phalanges. Phalanges are the bones of the fingers and toes.
Step 3: Focus on the carpals. The carpals are a set of eight small bones arranged in two rows. They include the scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate.
Step 4: Recall that the carpals are the correct answer because they specifically make up the wrist joint and provide its structure and movement capabilities.
Step 5: Conclude by noting that the radius, metacarpals, and phalanges are not part of the wrist itself, but are anatomically connected to it in different ways.
