Flashcards in Anatomical, Position, Direction, and Action Terminology Deck (32):
1

anatomy

The study of body structure. The oldest, most clinically relevant of the basic sciences.

2

anatomical position

* The body is standing erect with the face anterior (forward)
* Arms at the side
* Palms of hands turned anteriorly (forward)
* Eyes directed to the horizon

3

sagittal plane

A plane that divides the body into unequal right and left portions

4

Mid-sagittal plane

divides the body into left and right halves

5

Frontal/Coronal Plane

divides the body into anterior and posteriors portions

6

transverse/horizontal/cross-sectional plane

divides the body into superior and inferior portions

7

anterior

ventral, toward the front of the body

8

posterior

dorsal, toward the back of the body

9

superior

cephalic, towards the head

10

inferior

caudal, toward the feet

11

medial

towards the Mid-sagittal plane

12

lateral

away from the mid-sagittal plane

13

proximal

toward the center of the body

14

distal

away from the center of the body

15

superficial

toward the surface of the body

16

deep

toward the center of the body

17

ipsilateral

on the same side

18

contralateral

on the opposite side

19

somatic

refers to the body wall

20

visceral

refers to structures in the body cavity

21

flexion

decrease in anterior angle of a joint

22

extension

increase in anterior angle of a joint

23

abduction

movement away from the midline

24

adduction

movement toward the midline

25

pronation

turning the palm posteriorly

26

supination

turning the palm anteriorly

27

circumduction

combination of flexion, extension, abduction, adduction
(Ex: stick arm out, move in circle)

28

rotation

movement of a bone around its longitudinal axis
(Ex: Arm stays still, forearm moves back and forth on elbow joint)

29

inversion

turning sole of foot inward

30

eversion

turning sole of foot outward

31

doriflexion

approximating dorsum of foot to front of leg, pointing toes UPward

32

plantar flexsion

drawing hell upward, pointing toes downward
