Anatomical Reference Position:
all body segments are considered yo be orientated at 0o degrees
Directional terms
- Superior: top of body (chest and head)
- Inferior: lower body (legs and hips)
- Anterior: front of body
- Posterior: back of body
- Medial: midline
- Lateral:
- Proximal:
- Distal:
- Superficial:
- Deep:
- Extension: make angle of joint small (from anatomical position)
- Flexion: make angle of joint bigger (from anatomical position)
- Adduction: ulna deviation (add to body)
- Abduction: radial deviation (take away from body)
- Medial rotation: rotate into body
- Lateral rotation: rotate away from body
- Plantarflex: away from top of body (point foot)
- Dorsiflexion: top or up (flex foot up)
- Inversion: turn in (turn foot in)
- Eversion: turn out (turn foot out)
Anatomical Reference Planes – Cardinal planes
- Sagittal plane (median plane): midline to side of body YX
- Frontal plane (coronal plane): front of body ZX
· Adduction
· Abduction
· Lateral flexion
- Transverse plane (horizontal plane): split in body (hips and above or hips and below) XY
· Medial rotation
· Lateral rotation
· Horizontal flexion
· Horizontal extension
Anatomical Refence Axes: imaginary axes of rotation that passes through a joint to which it
is attached
- Mediolateral (x axis)
- Anteroposterior (y axis)
- Longitudinal (z axis)

Document Summary
Anatomical reference position: all body segments are considered yo be orientated at 0o degrees. Superior: top of body (chest and head) Extension: make angle of joint small (from anatomical position) Flexion: make angle of joint bigger (from anatomical position) Abduction: radial deviation (take away from body) Plantarflex: away from top of body (point foot) Dorsiflexion: top or up (flex foot up) Sagittal plane (median plane): midline to side of body yx. Frontal plane (coronal plane): front of body zx. Transverse plane (horizontal plane): split in body (hips and above or hips and below) xy. Anatomical refence axes: imaginary axes of rotation that passes through a joint to which it is attached. Intervertebral discs constitute approximately 98% of height. Arm bones: ulna = inside, radial = outside. Compact (cortical) forms outer shell and shafts in long bones. Spongy (cancellous) found at expanded heads of long bones. Roughly 95% of calcium and 90% of phosphorus is stored in bones and teeth.
