THE ANATOMIC POSITION
THE ANATOMIC POSITION
The anatomic position is a reference
position that defines specific surfaces
and planes of the body.
The anatomic position is an upright position
with arms abducted slightly (down), palms
forward, and head and feet directed
straight ahead
Anterior / Ventral :
front aspect of patient
Posterior / Dorsal :
Back aspect of the patient
Lateral aspect / position :
Refers to the side of-the patient
Medial aspect :
Pertaining / referring to the middle or midline
Dorsal / surface of the hand
Refers to the back or posterior aspect of the hand (dorsum manus)
Palmar surface of the hand
Refers to the palm of the hand; in the anatomic position, the same as the anterior or ventral surface of the hand
Plantar surface
Refers to the sole
or posterior
surface of the
foot
Dorsal surface of the foot
Refers to the top or anterior surface of the foot (dorsum pedis)
Proximal
Proximal (prok′-si-mal) is
near the source or beginning
Distal
Distal (dis′-tal) is away from.
- upper and lower limbs (proximal and
distal - part closest to/ away from the
trunk
Cephalad
Cephalad means toward the
head end of the body
Cephalad angle - any angle
toward the head end of the
body
Caudad
Caudad means away from
the head end of the body
Caudad angle - any angle
toward the feet or away from the head end
Superior
toward the head
Inferior
inferior (toward the feet)
Flexion
Flexion
decreases the angle of the
joint (see examples of
knee,
elbow, and wrist flexions)
Hyperextension
Hyperextension
Extending a joint beyond the
straight or neutral position.
Extension
Extension
increases the angle as
the body part moves
from a flexed to a
straightened position.
This is true for the knee,
elbow and wrist joints
Dorsiflextion
Dorsiflexion (wrist)
Backward or posterior
flexion (e.g. Wrist/ hand is
extended
beyond the neutral
position)
Dorsiflexion of foot
To decrease the angle
(flex) between the dorsum
(top of foot) and the lower
leg, moving foot and toes
upward.
Plantar flexion
Plantar flexion of
foot Extending the
ankle joint, moving foot
and toes downward from
the normal position;
flexing or decreasing the
angle toward the plantar
(posterior) surface of
the foot
Eversion
Eversion
an outward stress
movement of the foot
at the ankle joint
(The plantar surface (sole) of the
foot is turned or rotated away from
the median plane of the body (the
sole faces in a more
lateral direction)
