filtration angle

angle /an·gle/ (ang´g'l)

1. the point at which two intersecting borders or surfaces converge.

Scapula, showing the lateral, superior, and inferior angles.

2. the degree of divergence of two intersecting lines or planes.

---

acromial angle  the subcutaneous bony point at which the lateral border becomes continuous with the spine of the scapula.

axial angle  any line angle parallel with the long axis of a tooth.

cardiodiaphragmatic angle  that formed by the junction of the shadows of the heart and diaphragm in posteroanterior radiographs of the chest.

costovertebral angle  that formed on either side of the vertebral column between the last rib and the lumbar vertebrae.

angle of eye  canthus.

filtration angle  a narrow recess between the sclerocorneal junction and the attached margin of the iris, at the periphery of the anterior chamber of the eye; it is the principal exit site for the aqueous fluid.

iridial angle , iridocorneal angle, angle of iris filtration a.

line angle  an angle formed by the junction of two planes; in dentistry, the junction of two surfaces of a tooth or of two walls of a tooth cavity.

Louis' angle , Ludwig's angle sternal a.

optic angle  visual a.

point angle  one formed by the junction of three planes; in dentistry, the junction of three surfaces of a tooth, or of three walls of a tooth cavity.

angle of pubis  subpubic a.

sternal angle  the angle between the sternum and manubrium.

subpubic angle  that formed by the conjoined rami of the ischial and pubic bones.

tooth angles  those formed by two or more tooth surfaces.

venous angle  the angle formed by junction of the internal jugular and subclavian veins.

visual angle  the angle formed between two lines extending from the nodal point of the eye to the extremities of the object seen.

Y angle  that between the radius fixus and the line joining the lambda and inion.

filtration angle

n.

The acute angle occurring between the iris and the cornea at the periphery of the anterior chamber of the eye. Also called angle of the iris, iridocorneal angle.

angle

the space or figure formed by two diverging lines, measured as the number of degrees one would have to be moved to coincide with the other.

---

cardiodiaphragmatic angle

that formed by the junction of the shadows of the heart and diaphragm in radiographs.

costovertebral angle

the angle formed on either side of the vertebral column between the last rib and the lumbar vertebrae.

filtration angle

the angle between the iris and cornea at the periphery of the anterior chamber of the eye, through which the aqueous humor readily permeates. Called also angle of the iris.

glenoid angle

the angle of the scapula at the glenoid cavity, or ventral end, of the bone. The cranial and caudal angles are at the dorsal border of the scapula.

angle of inclination

see cervicofemoral angle.

angle of jaw

the junction of the ventral and caudal borders of the lower jaw.

nasofrontal angle

see stop.

oral lip angle

angle of union of the oral lips. Called also commissura labiorum.

sole angle

the angle formed by the inflection of the wall of the hoof to form the bars on the sole of the horse's foot. Called also angulus soleae medialis, lateralis.

filtration

passage through a filter or through a material that prevents passage of certain molecules, e.g. capillary wall, blood-brain barrier, radiographic grid.

filtration angle

developmental or acquired distortion of this part of the eye is the common cause of glaucoma. It is the space bounded by the sclera externally, the ciliary muscle posteriorly, the root of the iris medially and the anterior chamber of the eye anteriorly. Within the space is the filtering mechanism, a mass of anastomosing mesodermal spindle cells with many perforations between them.

filtration barrier

the physiological function which limits the passage of small molecules through the renal corpuscle.

glomerular filtration

the process by which glomerular filtrate is formed, involving the balance of pressures across the walls of the glomerular capillaries.

inherent filtration

attenuation of the primary x-ray beam as a result of its passage out of the x-ray tube through the insulating medium and tube window.

filtration membrane

the membrane which stretches across the filtration slits in the renal corpuscle.

filtration pressure

the net driving force which pushes fluid into tissue spaces and out of vascular sites; the net result between capillary osmotic pressure and intravascular hydrostatic pressure.

filtration slits

openings in the glomerular corpuscle which are part of the filtration process in the renal glomerulus.
