Study Notes
Skeletal System Functions
- Support
- Protection
- Assist in Movement
- Mineral Homeostasis
- Blood Cell Production
Bone Types
-
Axial: Located along the midline of the body
- Relative distance from midline: Middle
- Shapes: Long, flat, irregular
- Examples: Ribs
-
Appendicular: Located in the appendages
- Relative distance from midline: Middle/sides
- Shapes: Long/short, flat/irregular
- Examples: Femur
Bone Structure
-
Long Bone:
- Epiphysis: Ends of the bone, protect spongy bone
- Diaphysis: Shaft, protects compact bone
- Articular Cartilage: Prevents friction
- Periosteum: Covers bones, protects and strengthens diaphysis
- Spongy Bone: Ends/Center of bone, made of red/yellow bone marrow
- Compact Bone: Ends/center of bone, made of red/yellow bone marrow
- Yellow Marrow: Stores fat (energy), site of hemopoiesis
- Red Marrow: Site of hemopoiesis
Bone Cells
- Osteogenic: Bone-maker
- Osteoblast: Bone-maker, creates bone tissue
- Osteocytes: Maintains bone tissue
- Osteoclast: Bone-breaker, resorption
- Ossification: Process of bone formation
- Resorption: Process of breaking down bone.
Bone Markings
- Haversian/central canal
- Lacunae
- Lamellae
- Canaliculi
Bone Girdles:
- Pectoral Girdles: Two scapula bones (2)
- Pelvic Girdles: Two large coxal bones (1)
- Assist with supporting the body
