osmolality

DEFINITION:

The concentration of an osmotic solution especially when measured in osmols or milliosmols per 1000 grams of solvent.
Osmolality is a measure of the concentration of particles in a solution. A highly concentrated solution will have a high osmolality. That is, it will have more particles per unit of solvent than a solution with a low osmolality. (JC)

kidney

DEFINITION:

One of a pair of vertebrate organs situated in the body cavity near the spinal column that excrete waste products of metabolism, in man are bean-shaped organs about 4-1/2 inches long lying behind the peritoneum in a mass of fatty tissue, and consist chiefly of nephrons by which urine is secreted, collected, and discharged into a main cavity whence it is conveyed by the ureter to the bladder.

osmometer

DEFINITION:

A device for measuring osmotic concentration or pressure.

equilibration

DEFINITION:

The achievement of a balance between opposing elements or forces.

chamber

DEFINITION:

An enclosed space or antrum.

medullary

DEFINITION:

Pertaining to the marrow or to any medulla; resembling marrow.

adhere

DEFINITION:

To stick to something.

geometry

DEFINITION:

1. The branch of mathematics that deals with the deduction of the properties, measurement, and relationships of points, lines, angles, and figures in space from their defining conditions by means of certain assumed properties of space.

2. Any specific system of this that operates in accordance with a specific set of assumptions.

3. The study of this branch of mathematics.

4. A book on this study, especially a textbook.

5. The shape or form of a surface or solid.

6. A design or arrangement of objects in simple rectilinear or curvilinear form.

spatial

DEFINITION:

Pertaining to space.

resolution

DEFINITION:

1. The subsidence of a pathologic state, as the subsidence of an inflammation, or the softening and disappearance of a swelling.
2. The perception as separate of two adjacent objects or points. In microscopy, it is the minimal distance at which two adjacent objects can be distinguished as separate. The resolving power of an instrument depends on the wavelength of the radiation used and the numerical aperture of the system; it is expressed in microns distance or lines per millimeter.

permission

DEFINITION:

Formal consent; authorization.
