An Introduction to the Skeletal System 1 the skeletal system A bones B cartilages C ligaments D bone marrow production of red blood cells reticular tissue Functions of the Skeletal System 1 ve primary functions A support B storage of minerals and lipids stored in yellow bone marrow C red blood cell production erythropoiesis D protects organs E provides levers for force of motion Classi cation of Bones 1bones A are classi ed by ashape b internal tissue organization c bone marking surface features six bone shapes A sutural wormian B irregular C short D long E at F sesmoid knee cap sutural bones A small irregular bones B example bones in between at bones of the skull irregular bones A have complex shapes B examples sphenoid bone 4 foramen vertebral column sacrum coccyx and zygomatic bone short bones A small and thick B cube shaped C examples carpals 8 of them and tarsals atbones A thin with parallel surfaces B examples frontal parietal sternum scapula and clavicle 7 long bones A long and thin B examples femur radius bula tibia metacarpals metatarsals ulna and humerus 8 sesamoid bones A small and at specialized short bones B examples patella metatarsal l 9 bone markings A depressions or grooves a long bone surfaces sulcus or fossa b examples sulcus B elevation or projections a process bump in bone and ramus extension of bone forming an angle b example mandibular ramus C tunnels a long openings where vessels can travel b examples ssure foramen canal meatus D sinuses a create air spaces 10 structure of a long bone A diaphysis a shaft of bone b heavy wall of compact bone c medullary cavity is lined by endosteum and made or lled with yellow marrow B epiphysis a wider parts of the bone proximal or distal at each end b mostly spongey bone c covered by a thin layer of compact bone d lled with red bone marrow C metaphysis a connection between epiphysis and diaphysis meet 11 structure or a at bone A example cranial bones B resembles a sandwich of spongey bone C between two layers or compact bone D within the cranium the layer of spongy bone between the compact bone is called the diploe
