The document summarizes the spinal and pelvic bones. It describes the 33 vertebrae that make up the vertebral column and their five divisions. Each vertebra has a body, vertebral arch, and processes for muscle attachment. The vertebral column encloses the spinal cord, forms the body's central axis, and carries the body's weight above the pelvis. The pelvis is formed from three bones on each side - the ilium, ischium, and pubis - that meet at the pubic symphysis in front and sacroiliac joints behind. The male and female pelvis differ in structure.

2. Vertebral column bones
Bones Column of 33 small bones called VERTEBRAE
Begin at the cranium and end at the coccyx
5 Divisions:
● Cervical (7)
● Thoracic (12)
● Lumbar (5)
● Sacrum (5 fused)
● Coccyx (4 fused)

3. Funcions of vertebral column
it encloses the spinal cord,
shielding it from damage
the vertebral column forms
the central axis of the body
it has roles in both posture
and movement
it carries the weight of the
body above the pelvis
Protection
Axis Movement

4. While vertebrae have unique regional features, each vertebra has three main parts:
● Body (purple)
● Vertebral Arch (green)
● Processes for muscle attachment (tan)
Vertebral structure

5. ● Anterior part of vertebra
● Weight-bearing component
● Size increases as vertebral column descends
Vertebral body

6. ● Consists of 2 pedicles and 2 lamina
● Forms a hole for spinal cord called the VERTEBRAL FORAMEN
Vertebral arch

7. Serve as attachment points for muscles and create joints that allow for movement of the
spine
● Spinous Process
● Transverse Process (2)
● Superior Facet (2)
● Inferior Facet (2)
Processes (7 on each one)
