[L. angulus, corner, angle]
1. The figure or space outlined by the diverging of two lines from a common point or by the meeting of two planes.
2. A projecting or sharp corner.
The orientation of the patella relative to the tibial tubercle. The angle is formed by the intersection of a line bisecting the long axis of the patella and a passed through the tibial tubercle to the apex of the inferior pole of the patella.
A ANGLE The A angle is the relationship between the long axis of the patella and the tibial tuberosity; the Q angle describes the relationship between the long axis of the femur, measured from the anterior superior ilac spine.
The angle formed by the junction of the lateral and posterior borders of the acromion.
An angle less than 90°.
The angle formed by intersection of the visual line with the optic axis.
The angle between the horizontal plane and a line drawn through the base of the nasal spine and the middle point of the alveolus of the upper jaw.
The angle between the cornea and iris at the periphery of the anterior chamber of the eye.
The angle formed by the meeting of the axes of the orbits.
The medial inferior corner of the pleural cavity bordered by the heart and diaphragm.
The angle in the sagittal plane made at the elbow by extending the long axis of the forearm and the upper arm. This obtuse angle is more pronounced in women than in men.
In radiology, angulation of the central ray toward the patient's feet.
The angle formed by two or more walls of a cavity preparation in restorative dentistry.
In radiology, angulation of the central ray toward the patient's head.
The angle formed by intersecting anthropometric lines. It is used in studies of the skull and for the diagnosis of malocclusions of dental, skeletal, and dentoskeletal origin.
The angle formed by the junction of the cerebellum and the pons.

The angle between the visual axis and the median line when an object is looked at.
The meeting point of the lower border of the false ribs with the axis of the sternum.
The lateral inferior corner of the pulmonary cavity bordered by the ribs and diaphragm.
The angle formed on each side of the trunk by the junction of the last rib with the lumbar vertebrae.
The angle formed by the basifacial and basicranial axes at the midpoint of the sphenoethmoidal suture.
The angle made by lines from the nasal spine and external auditory meatus meeting between the upper middle incisor teeth.
The angle between two lines that join at an angle of almost 180°.
The angle between the line of vision and the optic axis.
SEE: Angle of jaw.
The angle between a ray striking a surface and a line drawn perpendicular to the surface at the point of incidence.
The angle between the femoral neck and the shaft of the femur. This angle is normally 35° in infancy; with maturation of the skeleton it increases to 45°.
SYN: SEE: cervicofemoral angle
SEE: Angle of jaw.
The angle between the base of the skull and the pterygoid process.
An angle greater than 90°.
The angle formed at the opisthion by the intersection of lines from the basion and from the lower border of the orbit.
The angle formed at the anterior nasal spine by the intersection of lines drawn from the auricular point and the glabella.
The angle formed by the meeting of a line drawn tangent to the maximum curve of the zygomatic arch and a line drawn tangent to the end of the maximum frontal diameter of the skull. If these lines are parallel, the angle is zero; if they diverge, a negative angle is formed.
In dentistry, a wheel containing pieces of wire. It is used for cleaning metal surfaces.
The angle formed by the junction of the rami of the pubic bones.
The acute angle formed by a line from the anterior superior iliac spine of the pelvis through the center of the patella and a line from the tibial tubercle through the patella. The angle describes the tracking of the patella in the trochlear groove of the femur. In women, the Q angle should be less than 22° with the knee in extension and less than 9° with the knee in 90° of flexion. In men, the Q angle should be less than 18° with the knee in extension and less than 8° with the knee in 90° of flexion.
SEE: A angle for illus
The angle formed by a refracted ray of light with a line perpendicular to the surface at the refraction point.
An angle of 90°.
The angle formed by articulation of the last lumbar vertebra and the sacrum.
The angle formed by the base of the sacrum and the fifth lumbar vertebra.
The angle formed at the top of the sella turcica by the intersection of lines drawn from the nasal point and the tip of the rostrum of the sphenoid.
The angle formed by the junction of the manubrium and the body of the sternum.
The sharp curve at the duodenojejunal junction.
The angle formed by the junction of the internal jugular and subclavian veins.
The angle between the line of sight and the extremities of the object seen.
