Study Notes
Skull
- Consists of cranial and facial bones
- Cranial bones surround the brain
- Frontal bone (front)
- Parietal bone (top)
- Occipital bone (back)
- Temporal bone (beside ear)
- Sphenoid bone (anterior to temporal)
- Ethmoid bone (midline, posterior to nose, inferior to frontal)
- Facial bones form face structure
- Nasal bone (bridge of nose)
- Maxilla (connects nose, cheekbones, upper teeth)
- Zygomatic bones (cheekbones)
- Mandible (jaw bone, connects to temporal at TMJ)
Spine
- Composed of vertebrae
- 7 Cervical vertebrae (C1-C7)
- C1 (Atlas)
- C2 (Axis)
- 12 Thoracic vertebrae (T1-T12)
- 5 Lumbar vertebrae (L1-L5)
- Sacrum
- Coccyx
- 7 Cervical vertebrae (C1-C7)
- Vertebrae numbered superior to inferior
Upper Limb
- Clavicle (collarbone) - horizontal, between sternum and shoulder
- Scapula (shoulder blade) - flat, triangular, posterior
- Humerus (upper arm bone)
- Glenoid fossa (concave area on scapula, meets humerus head for glenohumeral joint)
- Radius and ulna (elbow joint)
- 8 Carpal bones (wrist)
- 5 Metacarpal bones (hand) - numbered 1 to 5 (thumb to little finger)
- Phalanges (fingers and thumb)
- Proximal, middle, and distal phalanges in fingers
- Proximal and distal phalanges in thumb
- Joints: MCPs, PIPs, DIPs, CMC
Thorax
- Clavicle (top), attaches to sternum at sternoclavicular joint
- Sternum: manubrium (top), body, xiphoid process (end)
- 12 Ribs (one for each thoracic vertebra)
- 1–12 numbered
- Costal cartilages connect ribs to sternum
- Floating ribs (11th and 12th) - do not connect to sternum
Pelvis
- Three main bones: ilium, ischium, pubis
- Sacrum (base of spine), attaches to ilium at sacroiliac joint
- Pubis bones (front), join at pubic symphysis
- Ischium (inferiorly)
- Acetabulum (hip joint socket) - formed by the meeting point of all three pelvis bones
Lower Limb
- Femur (thigh bone) - longest bone in body
- Head connects to acetabulum for hip joint
- Tibia and fibula (lower leg), form knee joint
- Tibia - medial
- Fibula - lateral
- Patella (kneecap)
- Tarsal bones (ankle)
- 7 tarsal bones
Ankle and Foot
- Tarsal bones (ankle joint)
- Talus – connects to tibia and fibula
- Calcaneus
- Cuboid
- Navicular
- Three cuneiform bones
- Metatarsals (5), numbered 1 to 5 (big toe to little toe)
- Phalanges - proximal, middle, and distal, except big toe (only proximal and distal)
