anatomic position

anatomic position,

a standard position of the body: standing erect, facing directly forward, feet pointed forward and slightly apart, and arms hanging down at the sides with palms facing forward. This position is used as a reference to describe sites or motions of various parts of the body.

anatomic position,

n a reference posture of the human body, in which the anterior view of the human body is shown standing with legs slightly apart, feet forward, palms facing forward.

Anatomic position.

position,

n the placement or location of body parts to each other or the relationship of the body and its parts to other objects in space.

position, anatomic,

n the upright, forward-facing stance used to reference the physical location of a body part. Arms are held down at the sides with palms, toes, and eyes all directed anteriorly.

position, axial,

n the placement of the long axis of a tooth so that the tooth is positioned to withstand the occlusal forces exerted on it.

position, border, posterior,

n the most posterior position of the mandible at any specific vertical relation of the maxillae.

position, centric,

n 1. the position of the mandible in its most retruded relation to the maxillae at the established vertical relation.
n 2. the constant position into which the patient will close the jaws; this relationship may be a convenience relationship or a true centric relationship.

position, condylar hinge,

n 1. mandibular joints at which a hinge movement of the mandible is possible.
n 2. the maxillomandibular relation from which a consciously stimulated true hinge movement can be executed.

position, eccentric,

n (eccentric jaw position), any position of the mandible other than that in centric relation. See also relation, jaw, eccentric.

position, eccentric jaw,

n See position, eccentric and relation, eccentric jaw.

position, finger,

n See finger positions.

position, gingival,

n See gingival position.

position, hinge,

n the orientation of parts in a manner permitting hinge movements between them.

position, intercuspal,

n the term applied to the cuspal contacts of teeth when the mandible is in centric relation. Also called
centric occlusion.

position, mandibular hinge,

n any position of the mandible that exists when the condyles are so situated in the temporomandibular joints that opening or closing movements can be made on the hinge axis. See also axis, hinge.

position, neutral,

n a relaxed and level arrangement of specific parts of the body so as to minimize stress or strain on the joints, nerves, or spine. The neutral position is usually defined by the horizontal plane of the adjacent part(s).

position, physiologic rest,

n the habitual postural position of the mandible when the patient is resting comfortably in the upright position and the condyles are in a neutral, unstrained position in the glenoid fossae. The mandibular musculature is in a state of minimum tonic contraction to maintain posture and to overcome its force of gravity. See also relation, rest jaw.

position, protrusive,

n the occlusion of the teeth as the mandible and mandibular central incisors are moved straight forward toward the incisal edges of the upper central incisors; the normal anterocclusal relationship; the forward end position, with the maxillary and mandibular incisors in edge-to-edge contact.

position, rest,

n 1. the position of the mandible when the jaws are in rest relation. See also position, physiologic rest, and relation, rest jaw.
n 2. the position that the mandible passively assumes when the mandibular musculature is relaxed.

position, semi-upright,

n a way to position a patient suffering from respiratory or cardiovascular conditions.

position, terminal hinge,

n the mandibular hinge position from which further opening of the mandible would produce translatory rather than hinge movement. See also position, hinge.

position, tooth,

n the placement or location of the tooth in the dental arch in relation to the bone of the alveolar process, its adjacent teeth, and the opposing dentition.

position, Trendelenburg

n.pr a position in which the patient is on his back with the head and chest lowered and the legs elevated.
