Study Notes
Skull
- Skull composed of 22 bones joined by sutures (fibrous joints) for stability and limited movement
- Cranial bones (8) protect the brain
- Frontal bone (forehead, superior eye sockets)
- Parietal bones (2) (superior and lateral aspects)
- Temporal bones (2) (side of head, inner ear, connect to lower jaw)
- Occipital bone (back and base of skull, connects to spinal column)
- Sphenoid bone (base of skull, supports anterior skull base)
- Ethmoid bone (small, between orbital and nasal cavities)
- Facial bones (14) support the face and house sensory organs
- Maxillae (2) (upper jaw, upper teeth, articulates with other facial bones)
- Palatine bones (2) (part of hard palate, separates oral and nasal cavities)
- Zygomatic bones (2) (cheekbones)
- Nasal bones (2) (bridge of nose)
- Lacrimal bones (2) (medial wall of orbit, tear channels)
- Vomer (part of nasal septum, divides nasal cavity)
- Mandible (lower jaw) (largest, strongest facial bone, connects to temporal at TMJ for movement)
- Cranial sutures are important fibrous joints connecting skull bones:
- Coronal suture (frontal and parietal)
- Sagittal suture (two parietal bones)
- Lambdoid suture (parietal and occipital)
- Squamous sutures (temporal and parietal)
- Foramina and processes allow passage of nerves, blood vessels
- Foramen magnum, optic canal internal acoustic meatus are examples
- Skull develops via intramembranous ossification from mesoderm, starting with flat bones, followed by base
- Skull growth continues into adolescence, suture fusion in young adulthood
- Skull fractures can damage brain, nerves, blood vessels, requiring treatment (surgery possible)
- Variations in skull shape and size occur due to genetic factors
Spine (no changes)
- Spine composed of vertebrae (C1-C7, T1-T12, L1-L5, sacrum, coccyx)
- Vertebrae numbered superior to inferior.
- C1 (atlas) and C2 (axis) are named differently.
Upper Limb (no changes)
- Clavicle, scapula, humerus, radius, ulna, carpals, metacarpals, phalanges
- Joints: glenohumeral, elbow, MCP, PIP, DIP, CMC
Thorax (no changes)
- Sternoclavicular joint, sternum (manubrium, body, xiphoid), ribs (1-12), costal cartilages, floating ribs (11, 12)
Pelvis (no changes)
- Ilium, ischium, pubis bones, sacroiliac joint, pubic symphysis, acetabulum
Lower Limb (no changes)
- Femur, tibia, fibula, patella, hip joint, knee joint
Ankle and Foot (no changes)
- Tarsal bones (talus, calcaneus, cuboid, navicular, cuneiforms), metatarsals, phalanges
