Skeletal Structure and Features

  1. Axial Skeleton:
    • Description: The axial skeleton includes the bones along the central axis of the body.
    • Bones: Skull, vertebral column, rib cage (ribs and sternum).
    • Function: Provides support and protection for the brain, spinal cord, and organs of the thorax.
  2. Appendicular Skeleton:
    • Description: The appendicular skeleton includes the bones of the limbs and their attachments.
    • Bones: Upper limbs (arms, shoulders, hands) and lower limbs (legs, hips, feet), including the pectoral girdle (scapula and clavicle) and pelvic girdle (pelvis).
    • Function: Facilitates movement and locomotion, and supports the attachment of muscles involved in these actions.
Bony Features and Their Functions
  1. Processes:
    • Description: Processes are bony projections or outgrowths that serve as attachment points for muscles, tendons, and ligaments.
    • Examples: Spinous process of vertebrae, mastoid process of the temporal bone…
