Study Notes
Overview
The human skeleton is a complex system of 206 bones that provide support, protection, and movement for the human body.
Functions
- Support: The skeleton provides a framework for the body, allowing it to maintain its shape and providing attachment points for muscles.
- Protection: The skeleton protects internal organs, such as the heart, lungs, and brain, by encasing them in a protective cage of bones.
- Movement: The skeleton enables movement by providing a system of levers and joints that allow for flexibility and mobility.
Divisions
- Axial skeleton: 80 bones that make up the skull, spine, ribs, and sternum.
- Appendicular skeleton: 126 bones that make up the upper and lower limbs, pelvis, and shoulder girdle.
Bone Types
- Long bones: Longer than they are wide, e.g. femur (thigh bone).
- Short bones: Approximately equal in length and width, e.g. carpals (wrist bones).
- Flat bones: Thin and flat, e.g. ribs.
- Irregular bones: Do not fit into any other category, e.g. vertebrae.
Joints
- Synovial joints: Freely movable joints, e.g. shoulder, elbow, wrist.
- Cartilaginous joints: Partially movable joints, e.g. spine.
- Fibrous joints: Immovable joints, e.g. skull bones.
Bone Markings
- Processes: Bony outgrowths that serve as attachment points for muscles and ligaments.
- Fissures: Grooves or slits in bones that provide pathways for nerves and blood vessels.
- Foramina: Holes in bones that allow passage of nerves and blood vessels.
Development and Growth
- Ossification: The process of bone formation, which occurs through childhood and adolescence.
- Epiphyseal plates: Areas of cartilage at the ends of long bones that facilitate growth.
- Bone remodeling: The process of bone resorption and formation, which continues throughout life.
