Chapter 5 System 2 Skeletal System Flashcards
epiphysis
is an enlarged area on the ends of long bones that articulate with other bones
articular cartilage
is a layer of hyaline cartilage covering the end surface of the epiphysis
diaphysis
is the bone shaft between the epiphyses
periosteum
is a fibrous membrane that functions to protect the bone and serves as an attachment of tendons and ligamnets
the skeletal system is composed of? (3)
bones
cartilage
ligaments
the 5 main functions of the skeletal system are?
framework protect internal organs and tissue attachment points manufacture blood cells store minerals; calcium phosphate, calcium carbonate, magnesium, sodium
what is the composition of bone?
1/3 animal matter; bone cells, blood vessels, connective tissues, marrow
2/3 mineral or earthly matter
what are the 5 types of bone in the body?
flat - skull, pelvis, and ribs long - legs, arms, fingers, toes short - carpals and tarsals irregular - vertebrae sesamoid - patella
compact bone tissue
forms the hard bone found in the shafts of long bones and along the outside of flat bones
cancellous bone
located inside long bones and flat bones, consists of irregularly shaped spaces defined by thin. bony plates
medullary cavity
is a hollow chamber formed in the shaft of long bones that is filled with yellow bone marrow
marrow
is the connective tissue filling in the cavities of bones that forms red and white blood cells
for proper bone growth and hardening of bony structures, the diet should consist of an adequate amount of what?
calcium, phosphorus, vitamin D
axial skeleton
is made up of bones of the skull, thorax, vertebral column, and the hyoid bone
appendicular skeleton
is made up of bones of the shoulder, upper extremities, hips, and lower extremities
