(plan) [L. planum, flat surface]
1. A flat or relatively smooth surface.
Enlarge picture
2. A flat surface formed by making a cut, imaginary or real, through the body or a part of it. Planes are used as points of reference by which positions of parts of the body are indicated. In the human subject, all planes are based on the body being in an upright anatomical position. See: illustration; anatomical position
3. A certain stage, as in levels of anesthesia.
4. To smooth a surface or rub away.

Addison plane

alveolocondylar plane

A plane tangent to the alveolar point with most prominent points on lower aspects of condyles of the occipital bone.

axiolabiolingual plane

A plane that passes through an incisor or canine tooth parallel to the long axis of the tooth and in a labiolingual direction.

axiomesiodistal plane

A plane that passes through a tooth parallel to the axis and in a mesiodistal direction.

Baer's plane

See: Baer's plane

bite plane

A plane formed by the biting surfaces of the teeth.

coccygeal plane

The fourth parallel plane of the pelvis.

coronal plane

A vertical plane at right angles to a sagittal plane. It divides the body into anterior and posterior portions.
Synonym: frontal plane

datum plane

An assumed horizontal plane from which craniometric measurements are taken.

focal plane

One of two planes through the anterior and posterior principal foci of a dioptric system and perpendicular to the line connecting the two.

Frankfort horizontal plane

frontal plane

Coronal plane.

Hodge's plane

See: Hodge, Hugh Lennox

horizontal plane

A transverse plane at right angles to the vertical axis of the body.

inclined planes of the pelvis

Anterior and posterior inclined planes of the pelvic cavity, two unequal sections divided by the sciatic spines. In the larger, anterior section, the lateral walls slope toward the symphysis and arch of the pubes; the posterior walls slope in the direction of the sacrum and coccyx. The anterior inclined planes are the declivities over which rotation of the occiput takes place in the mechanism of normal labor.

inclined plane of a tooth

Any sloping surface of the cusp of a tooth.

intertubercular plane

A horizontal plane passing through the tubercles of the crests of the ilia; lies approx. at the level of the fifth lumbar vertebra.

Listing's plane

See: Listing's plane

median plane

A vertical plane through the trunk and head dividing the body into right and left halves. Synonym: midsagittal plane
See: plane for illus.

midsagittal plane

Median plane.

Morton's plane

See: Morton's plane

occlusal plane

An imaginary plane extending from the incisal edge of the incisors along the tips of the cusps of the posterior teeth to contact the cranium. Although not a true plane, it represents the mean of the curvature of the occlusal surface.

parallel planes of the pelvis

The planes intersecting the axis of the pelvic canal at right angles. The first plane is that of the superior strait; the second that extending from the middle of the sacral vertebra to the level of the subpubic ligament. The third plane is at the level of the spines of the ischia, and the fourth plane is at the outlet.

planes of the pelvis

Imaginary planes touching the same parts of the pelvic canal on both sides.

plane of refraction

A plane passing through a refracted ray of light and drawn perpendicular to the surface at which refraction takes place.

plane of regard

A plane through the fovea of the eye; fixation point.

sagittal plane

A vertical plane through the longitudinal axis of the body or part of the body, dividing it into right and left parts. If it is through the anteroposterior midaxis and divides the body into right and left halves, it is called a median or midsagittal plane.

subcostal plane

A horizontal plane passing through the lowest points of the 10th costal cartilages. It lies approx. at the level of the third lumbar vertebra.

transverse plane

A plane that divides the body into a top and bottom portion.

treatment plane

A plane in the concave joint surface that defines the direction of joint mobilization techniques. The plane is perpendicular to a line drawn from the axis of rotation in the convex joint surface to the center of the concave surface. Joint distraction techniques are applied perpendicular to, and gliding techniques parallel to, the treatment plane.

vertical plane

Any body plane perpendicular to a horizontal plane.

visual plane

A plane passing the visual axis of the eye.

It has been suggested that the frontal plane lower limb alignment is highly associated with the magnitude of external knee adduction moment in walking (Barrios et al., 2009; Barrios and Strotman, 2014; Hurwitz et al., 2002; Messier et al., 2014; Stief et al., 2011; Turcot et al., 2013).
Posture of the participants was analyzed from the photographs in both the sagittal and frontal planes. A statistically significant relationship was found between habit and postural defect.
The main results of the study demonstrated that persons with moderate medial knee OA exhibit different movement patterns for frontal plane trunk lean compared to healthy controls.
In addition, physiological evidence shows that the gastrocnemii muscles contribute to active control over ML ankle motion to stabilize the body in the frontal plane and may be related to the degree of challenge to stability [30].
The frontal plane P wave axis is directed to the region of +45[degrees] clockwise to +65[degrees].
Tibialis anterior has an important role in ankle stiffness by pressing the lateral side of the foot during stance and control of balance in the frontal plane. (20) The level of force variability in the tibialis anterior muscle, in static phase is higher than the dynamic phase in elderly.
The horizontal displacement of the torso along the frontal plane was evaluated using sensors (Polhemus--model Liberty 240/8, Colchester VT, USA) located at C7 and L5/S1.
The angular displacement of the knee joint in the frontal plane is shown in Fig.
