Question | Answer |
---|---|
sagittal plane | vertical division of the body into right and left portions (mid sagittal |
parasagittal | sagittal section that is divided into two left and right parts |
coronal (frontal) plane | (aka frontal plane); separates body from front and back. (Ventral or anterior = front half and dorsal or posterior = back half) |
transverse (horizontal) plane | horizontal division of the body into upper and lower portions |
superior direction | towards the head |
inferior direction | towards the feet |
anterior | toward the front plane of the body (biped) near the head end (quadruped) |
posterior | or toward the spine in primates at or near the hind end in quadrupeds |
medial | toward the midline of the body |
lateral | away from the midline |
proximal | closer to the origin of the body part or the point of attachment of a limb to the body trunk |
distal | situated farthest from point of attachment or origin |
external | outward features |
internal | located inward |
endocranial | inner surface of the cranial vault |
ectocranial | outer surface of the cranial vault |
palmar | palm side of the hand |
plantar | Sole of foot |
dorsal | top of the foot or back of the hand |
flexion | Bending or Decreasing the angle between bones |
extension | increasing the angle between bones |
abduction | moving of a body part away from the saggital plane |
adduction | moving of a body part towards the saggital plane |
circumduction | a circular movement of a limb/ combination of flexion extension abduction adduction |
rotation | one part turns on an axis |
opposition | parts are brought together |
pronation | rotation of the hands and forearms so that the palms face downward (anterior to posterior) |
supination | rotation of the hands and forearms so that the palms face upward |
dorsiflexion | foot flexion away from the ground |
plantarflexion | extension of the foot so that the toes point downward |
eversion | turning the sole outward or face away from midline |
inversion | turning sole inward or face towards midline |
process | bony prominence |
eminence | bony projection |

tuberosity | large rugose (roughened) eminence |
tubercle | small rugose eminence |
trochanter | on femur two large rugose processes |
malleolus | rounded protuberance (ankle joint) |
articulation | bones contact and form a joint |
condyle | rounded articular process |
epicondyle | non-articular projection beside condyle |
head | large rounded end (for articulation) |
shaft (diaphysis) | long straight section between the two ends of a bone |
epiphysis | ends of long bones (expanded) |
neck | section between the head and the shaft of a bone |
torus | bony thickening |
ridge | linear bony elevation (roughened) |
crest | prominent usually sharp and thin ridge |
line | raised linear surface |
hamulus | hook shaped projection |
facet | small articular surface |
fossa | depressed area broad and shallow |
fovea | pitlike depressed area |
groove | long pit or furrow |
sulcus | long wide groove |
fontanelle | space between cranial bones |
suture | cranial bones joint |
foramen | opening through a bone |
canal | tunnel like extened foramen |
meatus | short canal |
sinus | cavity within a cranial bone |
alveolus | tooth socket |
