Functions of the skeletal system1. Support= soft tissues and muscles attach to the skeleton 2. Protection= ribs protect underlying organs; skull protects the brain 3. Movement= attachment for muscles allows for movement 4. Hemopoiesis= the production of blood cells in the bone marrow 5. Mineral Storage= bone tissue contains large quantities of calcium, phosphate; can release calcium salts
Osteologystudy of bones
Axialbony and cartilaginous parts that support and protect the organs of the head, neck and trunk; includes skull, hyoid bone, vertebral column, sternum, ribs.
Appendicularbones of the limbs and associated bones that anchor the limbs and skeleton; includes pectoral girdle (scapula, clavicle), arms and hands, pelvic girdle, legs and feet.
Long Boneslonger than they are wide; function as levers (arm and leg bones)
Short Bonescube shaped; found in confined spaces; function to transfer forces (wrist and ankle bones)
Flat Bonesbroad, dense surface for muscle attachment or protection of underlying organs (ribs, scapula, skull)
Irregular Bonesvaried shaped for muscle attachment or articulation (vertebrae, facial bones)
Anatomical Positionstanding or lying flat, palms out (up); can be used to determine relative bone position.

pectoral/shoulder girdlesconsist of 2 bones- anterior clavicle and the posterior scapula; provide attachment points for many trunk and neck muscles
claviclecollarbone; its medial end attaches with the manubrium; the lateral end is flattened and articulates with the scapula to form part of the shoulder joint
scapulashoulder blades; "wings" of humans
glenoid cavitya shallow socket that receives the head of the arm bone (humerus); is located in the blunted lateral angle
trochleaarticulates with the ulna
