divisions of anatomy
planes
midsagital divides body into L/R-flextion/extension
parasagital divides body into unequal L/R parts
frontal divides body into front/back parts (asymmetrical)-abduction/adduction
transverse divides body into upper and lower parts-rotation
body cavities
dorsal: cranial cavity and vertebrae cavity
ventral: thoracic (superior mediastinum-middle chest, L/R pleural cavities, and pericardial cavity-heart), abdominal, pelvic cavities
what separates the thoracic and abominal cavities?
what separates the abdominal and pelvic?
- no structure, sometimes called abdominopelvic
functions of the skeletal system
types of bone
-long bone
-short bones-carpal region and tarsal
-flat bones, eg sternum, skull
irregular bones-vertebrae
-sesamoid bones-bones contained w/in the tendons of muscle (patella)
axial skeleton
appendicular skeleton
axial=skull, cranium, vertebral column, ribs, sternum
appendicular=upper and lower limbs, including clavicle/scapula shoulder girdle and L/R pelvic bones (attachment points of limbs to axial skeleton)
what movements occur only in the forearm?
what movements occur only in the ankle?
what movements occur only in the foot?
regions of the abdomen
