Study Notes
Skull
- Skull composed of cranial and facial bones
- Cranial bones surround the brain:
- Frontal bone (front)
- Parietal bone (top)
- Occipital bone (back)
- Temporal bone (beside the ear)
- Sphenoid bone (anterior to temporal)
- Ethmoid bone (midline, posterior to nose, inferior to frontal)
- Facial bones form facial structure:
- Nasal bone (nose bridge)
- Maxilla (connects nose, cheekbones, upper teeth)
- Zygomatic bones (cheekbones)
- Mandible (jaw bone, connects to temporal bone at TMJ)
Spine
- Spine contains vertebrae:
- 7 cervical vertebrae (C1-C7)
- 12 thoracic vertebrae (T1-T12)
- 5 lumbar vertebrae (L1-L5)
- Sacrum
- Coccyx
- Vertebrae numbered from top down
- C1 (atlas), C2 (axis) have specific names
Upper Limb
- Clavicle (collarbone) horizontally between sternum and shoulder
- Scapula (shoulder blade) flat, triangular bone at back
- Humerus (upper arm bone)
- Glenoid fossa (concave area on scapula)
- Glenohumeral joint (where humerus head meets glenoid fossa)
- Radius and ulna (connect humerus at elbow)
- 8 carpal bones (connect to radius and ulna at wrist)
- 5 metacarpal bones (numbered 1-5, from thumb to little finger)
- Phalanges (fingers and thumb):
- Proximal phalanx
- Middle phalanx (in most fingers)
- Distal phalanx
- Thumb: proximal and distal phalanges only
- Joints: MCPs (metacarpophalangeal), PIPs (proximal interphalangeal), DIPs (distal interphalangeal), CMC (carpometacarpal)
Thorax
- Clavicle at top of thorax, connects to sternum at sternoclavicular joint
- Manubrium (top part of sternum)
- Sternal angle (where manubrium meets sternum body)
- Xiphoid process (small bone at sternum end)
- 12 ribs (numbered 1-12, connect to thoracic vertebrae)
- Costal cartilage (connects ribs to sternum)
- Floating ribs (ribs 11 and 12, don't attach to sternum)
Pelvis
- Pelvis comprises ilium, ischium, and pubis
- Sacrum at base of spine, connects to ilium at sacroiliac joint
- Pubis bones (front), meet at pubic symphysis
- Ischium (inferiorly)
- Acetabulum (hip joint socket), formed by meeting point of pelvis bones
Lower Limb
- Femur (thigh bone), longest bone in body
- Hip joint formed by femur head and acetabulum
- Femur connects to tibia and fibula (lower leg), forming knee joint
- Tibia (medial), fibula (lateral)
- Patella (kneecap)
Ankle and Foot
- Ankle joint formed by tibia, fibula and tarsal bones
- 7 tarsal bones:
- Talus (ankle joint; connects to tibia and fibula)
- Calcaneus
- Cuboid
- Navicular
- 3 cuneiform bones
- 5 metatarsal bones (numbered 1-5; big toe to little toe)
- Phalanges (toes):
- Proximal, middle, and distal phalanges (except big toe with only proximal and distal)
