humor

 [hu´mor] (pl. humors, humo´res) (L.)
1. any fluid or semifluid in the body, adj., adj hu´moral.
2. in the nursing interventions classification, a nursing intervention defined as facilitating the patient to perceive, appreciate, and express what is funny, amusing, or ludicrous in order to establish relationships, relieve tension, release anger, facilitate learning, or cope with painful feelings.
aqueous humor the fluid produced in the eye and filling the spaces (anterior chamber and posterior chamber) in front of the lens and its attachments. It diffuses out of the eye into the blood and is regarded as the lymph of the eye, although its composition is different from that of the lymph in the rest of the body.
ocular humor either of the humors of the eye—aqueous or vitreous.
vitreous humor the fluid portion of the vitreous body; often used to designate the entire vitreous body.

a·que·ous hu·mor

[TA]
the watery fluid that fills the anterior and posterior chambers of the eye. It is secreted by the ciliary processes within the posterior chambers and passes through the the pupil into the anterior chamber where it filters through the trabecular meshwork and is reabsorbed into the venous system at the iridocorneal angle by way of the sinus venosus of the sclera;
Synonym(s): humor aquosus [TA], intraocular fluid

aqueous humor

n.
The clear, watery fluid circulating in the anterior and the posterior chambers of the eye.

aqueous humor

the clear, watery fluid circulating in the anterior and posterior chambers of the eye. It is produced by the ciliary body and is reabsorbed into the venous system primarily at the iridocorneal angle by means of the canal of Schlemm.

a·que·ous hu·mor

(ā'kwē-ŭs hyū'mŏr) [TA]
The watery fluid that fills the anterior chamber of the eye. It is secreted by the ciliary processes within the posterior chamber and passes through the pupil into the anterior chamber where it filters through the trabecular meshwork and is reabsorbed into the venous system at the iridocorneal angle by way of the sinus venosus of the sclera.

Aqueous humor

A transparent liquid, contained within the eye, that is composed of water, sugars, vitamins, proteins, and other nutrients.
Mentioned in: Glaucoma

aqueous

watery; prepared with water.

aqueous-blood barrier
see blood-aqueous barrier.
aqueous flare
turbidity of the aqueous humor caused by increased protein levels and cells.
aqueous humor
the fluid produced by the ciliary process in the eye and occupying the anterior and posterior chambers. It provides nourishment for the lens and cornea and maintains the ocular pressure, and hence the optical integrity of the eyeball. Disturbance of its drainage through the corneoiridial angle can induce glaucoma and other disorders.
aqueous misdirection
aqueous paracentesis
plasmoid aqueous
aqueous humor with a protein concentration approaching that of plasma; seen in inflammation or other disruption of the blood-aqueous barrier.
aqueous suspension
a mixture of insoluble particles in water.

humor

pl. humores, humors [L.] any fluid or semifluid in the body.

aqueous humor
see aqueous humor.
ocular humor
either of the humors of the eye—aqueous or vitreous.
vitreous humor
