Question | Answer |
what are the 6 functions of the skeletal system | support, protection, movement, blood cell formation, mineral storage, passageways for blood vessels and nerves |
support does what? | supports soft tissue |
protection does what? | protects internal organs? |
movement does what? | skeletal muscles contract, pull on bones, together movement |
blood cell formation does what? | red bone marrow produces blood cells |
mineral storage does what? | ca2 + an p |
passageways for blood vessels and nerves does what? | feature more then function |
two types of tissues | connective and nervals |
ends both proximal and distal epiphyses | epipthysis |
bone shaft, long main portion | diaphysis |
gristle at ends | articular cartilage |
outer lining | periosteum |
inner lining | endosteum |
dense bone tissue | compact bone |
bone separated by irregular spaces | spongy bone |
marrow cavity in shaft | medullary cavity |
connective tissue filling bone spaces | marrow |
arrangement of compact bone | osteon |
mature isolated bone cell | osteocyte |
cavity around osteocyte | lacunae |
vertical path for blood vessels | central canals |
horizontal path for blood vessels | perforating canals |
small canals that connect osteocytes to each other | canaliculi |
bone formed on or within fibrous connective tissue membranes | intramembranous |
bone formed in a cartilage model | endochondrial |
cartilage layer within a long bone where growth takes place | epiphyseal plate |
inside the spongy bone of flat bones and epiphysis of long bone | red marrow |
blood cell formation. production of rbcs, wbcs and platelets | hematopolesis |
what color happens due to hemoglobin in rbcs | red color |
inside medullary cavities of long bones, stores fat | yellow marrow |
what does bone marrow transplant treat | sickle cell disease and leukemia |
increase osteoclast activity decrease osteoblasts, more matrix/bone broken down release ca2 up blood ca2 | parathroid hormone (PTH) |
increase osteoblast activity, inhibit osteoblast, more ca2 + deposited into bone | calcitonin |
what regions does bones and cartilage that supports and protects the head neck and trunk | skull, hyoid bone, vertebral colum, thoratic cage |
what regions does bones of the upper and lower limbs and bones the connect limbs to the axial skeleton | pectoral girdle, upper limbs, pelvic girdle,lower limbs |
how many total bones are there | 206 |
rounded process that usually articulates with another bone | condyle |
interlocking union between bones | suture |
a prominent projection of a bone | process |
an opening through a bone usually a passageway for blood vessels, nerves, or ligaments | foramen |
tubelike passageway within a bone | meatus |
cavity within a bone | sinus |
relatively deep pit or deression | fossa |
infant soft spot, ossifaction is incomplete allowing skull compression durning delivery | fontanels |
what are the functions of the hyoid bone | supports the tounge |
regions does cervical have | 7 |
regions does thoracic have | 12 |
regions does lumbar have | 5 |
regions does sacrum have | 5 fused |
regions does coccyx have | 4 fused |
how many true ribs | 5 |
how many false ribs | 5 |
how many floating ribs | last 2 pairs |
supports the head with occipital condyles | atlas |
pivots to allow the head to turn | axis |
female smaller facial area more round jaw and mastoid process smaller | skull |
female coxae lighter thinner | pelvic girdle |
female cavity wider shorter roomier less funnel shaped | pelvic cavity |
female wider sacral curve bent more sharply | sacrum |
female more movable | coccyx |
remove calcium from bone spaces and canals appear weaking | osteoporosis |
protrusion of inner material of intervertebral disk | herniated slippled disk |
vitamin d deficiency | rickets |
vertebrae fail to join at the midline durning developement | spina bifida |
what are the mineral salts in bone | calcium carbonate(caco3) and calcium phosphate (ca3)(po4)2 |
