APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Your axial skeleton is made up of the 80 bones within the central core of your body. This includes bones in your skull (cranial and facial bones ), ears, neck, back (vertebrae, sacrum and tailbone) and ribcage (sternum and ribs).

Detailed explanation-2: -The axial skeleton together with the appendicular skeleton form the complete skeleton. Another definition of axial skeleton is the bones including the vertebrae, sacrum, coccyx, skull, ribs, and sternum.

Detailed explanation-3: -The adult vertebral column comprises 26 bones: the 24 vertebrae, the sacrum, and the coccyx bones. In the adult, the sacrum is typically composed of five vertebrae that fuse into one. The coccyx is typically 3–4 vertebrae that fuse into one. Around the age of 70, the sacrum and the coccyx may fuse together.

Detailed explanation-4: -The Axis (C2 vertebra) also known as epistropheus forms the pivot upon which the first cervical vertebra (the Atlas), which carries the head, rotates. The axis is composed of a vertebral body, heavy pedicles, laminae, and transverse processes, which serve as attachment points for muscles.

Detailed explanation-5: -The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum. The appendicular skeleton consists of 126 bones and includes the free appendages and their attachments to the axial skeleton.
