CORONAL/SAGITTAL/TRANSVERSE PLANES
Coronal Plane (Frontal Plane)
Sagittal Plane (Lateral Plane)
Transverse Plane (Axial Plane)
CORONAL PLANE aka Frontal Plane Vertical plane
running from side to side
Divides the body or any of its parts into anterior and posterior portions
SAGITTAL PLANE aka Lateral Plane vertical plane
running from front to back
Divides the body or any of its parts into right and left sides
TRANSVERSE PLANE aka Axial Plane Horizontal plane Divides the body or
any of its parts into upper and lower parts
ANTERIOR/POSTERIOR Anterior—to be
situated near or toward the front of the body
Posterior--to be situated toward the back of the body
SUPERIOR/INFERIORCRANIAL/CAUDAL
Superior—means to be situated toward the upper part or head of the body, positioned above another organ or structure
Inferior—to be situated toward the lower part of the body or positioned below another organ or structure
Cranial—refers to the head end Caudal—refers to the tail end
SUPERIOR/INFERIORCRANIAL/CAUDAL
MEDIAL/LATERAL Medial—to be closer
to the midline of the body or a structure, being internal as opposed to external
Lateral—to be farther away, in the direction of either side, from the midline of the body or a structure
PROXIMAL/DISTAL Proximal: Toward or
nearest the trunk or the point of origin of a part
Distal: Away from or farthest from the trunk or the point of origin of a part
AVASCULAR Without blood
circulation
ECTOPIC Occurring in an
abnormal position or place
UNILATERAL/BILATERAL Unilateral—on one side Bilateral—on both sides
ACUTE/CHRONIC Acute—symptoms appear and change/worsen
rapidly (heart attack) Chronic—develops and worsens over an extended
period of time (atherosclerosis)
IPSILATERAL/CONTRALATERAL Ipsilateral—on the same side as another structure
i.e. the left arm is ipsilateral to the left leg. Contralateral—on the opposite from another
structure i.e. the left arm is contralateral to the right arm, or
the right leg.
SUPERFICIAL/INTERMEDIATE/DEEP Superficial—near the outer surface of the
body i.e. skin is superficial to the muscle layer
Intermediate—between two other structures i.e. the naval is intermediate to (or
intermediate between) the left arm and the contralateral (right) leg.
Deep—further away from the surface of the body i.e. the muscular layer is deep to the skin, but
superficial to the intestines.
BODY CAVITIES Thoracic Cavity Abdominal and Pelvic
Cavity Dorsal Cavity
THORACIC CAVITY Upper ventral, thoracic or chest cavity
Contains: Heart Lungs Trachea Esophagus Large blood vessels Nerves
Bound laterally by ribs and the diaphragm caudally
ABDOMINOPELVIC CAVITY
Lower part of ventral cavity
Abdominal: Gastrointestinal tract Kidneys Adrenal glands
Pelvic: Urogenital system Rectum
DORSAL CAVITY Smaller of two main
cavities Upper portion:
Cranial cavity Brain
Lower portion: Vertebral canal
contains the spinal cord
FLEXION/EXTENSION
ABDUCTION/ADDUCTION Abduction—moving a body part away from
midline Adduction—moving a body part toward the
midline
ABDUCTION/ADDUCTION
INTERNAL/EXTERNAL ROTATION Internal rotation—
rotation towards the center of the body aka medial rotation
External rotation—rotation away the center of the body aka lateral rotation
INTERNAL/EXTERNAL ROTATION
HIP INTERNAL ROTATION
