Distributes oxygen to cells/transport waste products from cells
Circulatory
Absorption and elimination of nutrients
Digestive
Supplies oxygen/ eliminates carbon
Respiratory
Regulates blood / Eliminates waste products
Urinary
Regulates body activity

How many bones
Appendicular
126
Min. Of how many projections when joints are in prime interest area?
What positions?
3
AP/PA, lateral, oblique
What is AP or PA position?
Anterior to posterior (front to back)
Posterior to anterior
What is lateral position?
Side view
central ray, perpendicular to the sagittal plane and parallel to the coronal plane, passes from one side of body to the other
What is oblique position?
Through the side but at an angle
central ray passes through the body/body part through a plane which is at an angle to the transverse plane/coronal plane
Long bones require how many projections?
2
AP, lateral
found in vertebrae and facial bones
irregular bones
found in limbs; joints on distal and proximal ends
long bones
epiphyseal plates
area of growth on a bone
appendicular skeleton
shoulder, pelvis, limbs
found in the carpal and tarsal bones
short bones
