Skeletal System Overview
- Composed of 206 individual bones
- Connected by articulations, ligaments, and tendons
Types of Bones
- Long bones: Clavicle, humerus, radius, ulna, metacarpals, femurs, tibia, fibula, metatarsals, phalanges
- Short bones: Carpal and tarsal bones, patellae, sesamoid bones
- Flat bones: Skull, mandible, scapulae, sternum, ribs
- Irregular bones: Vertebrae, sacrum, coccyx, hyoid bone
Axial Skeleton
- Primarily composed of the skull and trunk
-
Skull:
- Neurocranium: Houses and protects the brain
- Viscerocranium: Maxilla and mandibles
-
Trunk:
- Vertebral column: Protects spinal cord (7 cervical, 12 thoracic, 5 lumbar, 5 fused sacrum, 4 fused coccyx)
