What are the bones of the appendicular skeleton attached to?

1. The central nervous system

2. The shoulders and pelvis

3. Directly to each other

4. The axial skeleton without intermediaries

The correct answer is: The shoulders and pelvis

The bones of the appendicular skeleton are attached to the shoulders and pelvis. This is because the appendicular skeleton is responsible for the movement and support of the limbs, and the shoulders and pelvis serve as the central hubs for the attachment of these limbs. Option A is incorrect because the central nervous system is primarily made up of the brain and spinal cord, which are not considered part of the skeletal system. Option C is incorrect because while some bones in the appendicular skeleton may be directly attached to each other, they are ultimately connected to the shoulders or pelvis. Option D is incorrect because the axial skeleton (which includes the skull, ribs, and spine) does not directly connect to the appendicular skeleton without the use of joints or other structures. Overall, the correct answer is B because it provides the most accurate and relevant explanation for the attachment of the bones of the appendicular skeleton.
