which bones are not part of the appendicular skeleton

The bones that are not part of the appendicular skeleton are those belonging to the axial skeleton. The axial skeleton forms the core structure of the body and includes the following bones:

Skull: This includes all the bones of the head, such as the cranium (frontal bone, parietal bones, occipital bone, sphenoid bone, temporal bones), mandible (lower jawbone), and facial bones (maxilla, zygomatic bone, nasal bone, lacrimal bone, vomer bone, palatine bone, ethmoid bone).

Vertebral column: This consists of 24 individual vertebrae (cervical, thoracic, lumbar, sacrum, and coccyx) that run down the back and form the spinal canal, which protects the spinal cord.

Rib cage: This consists of 12 pairs of ribs that connect to the thoracic vertebrae in the back and the sternum (breastbone) in the front.

Sternum: This flat bone forms the front of the chest cavity and connects to the ribs.
