Anterior
Front / Before
Ventral
Belly side (equivalent to anterior when referring to human body)
Posterior
Back / Behind
Dorsal
The Back (equivalent to posterior when referring to human body)
Cranial / Cephalic
Toward the Head
Superior
Above, at a higher level (in human body, towards the head)
Caudal
Toward the tail (coccyx in humans)
Inferior
Below, at a lower level (in human body, towards the feet)
Medial
Toward the midline (the longitudal axis of the body)
Lateral
Away from the midline (away from the long axis)
Proximal
Toward an attached bone
Distal
Away from an attached base
Superficial
At, near, or relatively close to the body surface
Deep
Toward the inferior of the body, farther from the surface
Sagittal Plane
Divides body in half parallel to the long axis (MRI)
Transverse Plane
Cross-section, Divides body in half at a right angle to long axis (MRI, CT)
Coronal Plane
Frontal Plane, Parallel with the longitudinal axis of the body and divides the body in anterior and posterior parts
Circumduction
Portion of the object remains stationary while the object held at an angle less than 90 degrees makes a complete circle
Rotation
A tip or part of an object remains stationary while the angle of the shaft remains unchanged as the shaft spins around its longitudinal axis
Abduction
Movement away from the longitudinal axis of the body in the frontal plane. Example; Arm moving away from body
Adduction
Movement towards the longitudinal axis of the body in the front plane. (think adding to body) Example; Arm moving towards body.
Flexion
Movement in the anterior and posterior plane that reduces the angle between the articulating joints. Example; Head bending forward
Extension
Movement in the anterior and posterior plane that increases the angle between the articulating joints. Example; Heading bending backward.
Internal Rotation
Medial Rotation, Limb rotates inward, toward the ventral surface of the body
External Rotation
Lateral Rotation, Limb rotates outward, toward the posterior surface of the body
Pronation
The motion of the wrist and palm to face downward
Supination
The motion of the wrist and palm to face upward
Eversion
Refers to the ankle, twisting motion of the foot that turns the sole outward
Inversion
Refers to the ankle, twisting motion of the foot that turns the sole of the foot inward.
Dorsiflexion
Ankle flexion that elevates the distal portion of the foot and toes toward the leg. Excludes toe movements
Plantar Flexion
Ankle extension that elevates the heel and proximal portion of the foot. Excludes toe movements
Lateral Flexion
Specific movement that cause the vertebral column to bend side to side
Protraction
Moving a part of the body anterior in the horizontal plane. Example; head coming forward
Retraction
Moving a part of the body posteriorly in the horizontal plane. Example; head moving back
