| sphenoid sinus | One of the paired paranasal sinuses, located in the body of the sphenoid bone and communicating with the highest meatus of the nasal cavity on the same side. (12 Dec 1998) |
|---|---|
| sphenoid sinusitis | Inflammation of the sphenoid sinus. This condition usually is accompanied by pansinusitis and may present itself in an acute or chronic form. (12 Dec 1998) |
| squamous border of sphenoid bone | The margin of the greater wing of the sphenoid bone that articulates with the squamous part of the temporal bone. Synonym: margo squamosus ossis sphenoidalis. (05 Mar 2000) |
| zygomatic border of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| zygomatic margin of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| frontal border of sphenoid bone | The margin of the greater wing of the sphenoid bon that articulates with the frontal bone. Synonym: margo frontalis ossis sphenoidalis. (05 Mar 2000) |
| lesser wing of sphenoid bone | One of a bilateral pair of triangular, pointed plates extending laterally from the anterolateral body of the sphenoid bone. Forming the posteriormost portion of the floor of the anterior cranial fossa, their sharp posterior edge forms the sphenoidal ridge separating anterior and middle cranial fossae. The medial end of the lesser wing attaches to the body by means of two pedicles, thus forming the optic canal. The wing itself forms the superior margin of the supraorbital fissure. Synonym: ala minor ossis sphenoidalis, ala orbitalis, Ingrassia's apophysis, Ingrassia's wing. (05 Mar 2000) |
| acromial angle | The prominent angle at the junction of the posterior and lateral borders of the acromion. Synonym: angulus acromialis. (05 Mar 2000) |
| acute angle | Any angle less than 90 |
| acute angle closure glaucoma | <ophthalmology> An increase in pressure within the anterior chamber of the eye. There are two forms of glaucoma: acute angle closure and open angle glaucoma. (27 Sep 1997) |
| adjacent angle | An angle with a line in common with another angle. (05 Mar 2000) |
| alpha angle | The angle between the visual and optic axes as they cross at the nodal point of the eye, the angle between the visual line and the major axis of the corneal ellipse. (05 Mar 2000) |
| alveolar angle | The angle between the horizontal plane and a line connecting the base of the nasal spine and the middle point of the projection of the alveolus of the maxilla. (05 Mar 2000) |
| angle | 1. To fish with an angle (fishhook), or with hook and line. 2. <geometry> The figure made by two lines which meet. The difference of direction of two lines. In the lines meet, the point of meeting is the vertex of the angle. 3. A projecting or sharp corner; an angular fragment. "Though but an angle reached him of the stone." (Dryden) Curvilineal angle, one formed by two curved lines. External angles, angles formed by the sides of any right-lined figure, when the sides are produced or lengthened. Internal angles, those which are within any right-lined figure. Mixtilineal angle, one formed by a right line with a curved line. Oblique angle, one acute or obtuse, in opposition to a right angle. Obtuse angle, one greater than a right angle, or more than 90 deg . Rectilineal or Right-lined angle, one formed by two right lines. Right angle, one formed by a right line falling on another perpendicularly, or an angle of 90 deg (measured by a quarter circle). Solid angle, the figure formed by the meeting of three or more plane angles at one point. Spherical angle, one made by the meeting of two arcs of great circles, which mutually cut one another on the surface of a globe or sphere. Visual angle, the angle formed by two rays of light, or two straight lines drawn from the extreme points of an object to the center of the eye. 4. <astronomy> A name given to four of the twelve astrological houses. Origin: F. Angle, L. Angulus angle, corner; akin to uncus hook, Gr. Bent, crooked, angular, a bend or hollow, AS. Angel hook, fish-hook, G. Angel, and F. Anchor. (16 Mar 1998) |
| angle closure glaucoma | <ophthalmology> Primary glaucoma in which contact of the iris with the peripheral cornea excludes aqueous humor from the trabecular drainage meshwork causing a sudden blockage of the normal fluid circulation within the eyeball resulting in increased intraocular pressure. Increased pressure within the eyeball can cause damage to the optic nerve and blindness. Symptoms include severe eye or facial pain, nausea, vomiting, decreased vision, blurred vision and seeing halos around objects. The eye appears red with a steamy cornea and a fixed (nonreactive) dilated pupil. Treatment is emergent with medications to lower the pressure within the eye. Synonym: acute glaucoma, closed-angle glaucoma, narrow-angle glaucoma. (14 Aug 2000) |
