Anatomical Terminology Flashcards
unit 1
Anatomical position
standard starting point of the body
1. upright (standing)
2. face and feet pointing forward
3. arms at side
4. supinated forearms
patients left and right
anatomic planes
sections of the body
Types of cardinal planes
-sagittal
-transverse (horizontal)
-frontal (coronal)
4th plane
oblique
Sagittal plane
-left and right side
-name comes from the sagittal suture in cranium
Mid-sagittal plane
equal left and right side
median
para-sagittal plane
unequal left and right side
Transverse plane
-cross-sectional plane
-superior section (upper)
-inferior section (lower)
Frontal plane
-front section (anterior)
-back section (posterior)
name comes from the coronal suture in the cranium
Oblique plane
-not horizontal or vertical
-diagonal
Anatomical axes
-describes the direction of a movement at a joint
-always rotate perpendicular to the plane of movement
3 types of axes
-horizontal axis
-longitudinal axis
-antero-posterior axis
Horizontal axis
-extends from one side to the other side of the body
ex. backflip, front roll
-flexion and extension
Longitudinal axis
-goes from head to toe
ex. a pirouette
-rotational movements
Antero-posterior axis
from the front to the back of the body
-add and abduction
think of a knife stabing you
Anterior
towards front of the body
Posterior
towards the back of the body
Superior
being closer to the top of the body
-not including limbs
inferior
being closer to the bottom of the body
-not including limbs
medial
towards the body’s midline
lateral
away from the body’s midline
proximal
towards upper section of a limb (closer to the point of attachment)
distal
towards lower section of a limb (away from to the point of attachment)
superficial
towards/at the surface of skin
deep
further away from skin’s surface
terms of direction
anterior, posterior, superior, inferior, medial, lateral, proximal, distal, superficial ,deep
terms of movement
flexion, extensions, abduction, adduction, internal rotation, external rotation, circumduction
flexion
decreasing angle of a joint by bringing bones closer
extension
increasing angle of a joint by bringing bone further apart
