SKELETAL SYSTEM

QuestionAnswer
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
