Synonym(s): caruncula lacrimalis [TA]

fleshy masses on the wall of the uterus of pregnant ruminants. The placenta is attached only at these points. There are about 100 of them and they are very much smaller in the nonpregnant female.
pertaining to tears.
a group of organs concerned with the production and drainage of tears; it is a nutritive and protective device that helps keep the eye moist and free of dust and other irritating particles. Includes lacrimal gland, accessory lacrimal glands, third eyelid glands and the nasolacrimal duct.
the lacrimal duct within the eyelid.
the rounded, often pigmented swelling at the medial canthus of the eye.
congenital displacement of lacrimal tissue results in subconjunctival cysts.
lacrimal drainage system
the structures concerned with tear collection; includes lacrimal lake, puncta, canaliculi, sac and nasolacrimal duct.
there are two of these minute ducts draining tears from the conjunctiva, via the lacrimal puncta, into the lacrimal sac. Called also lacrimal canaliculus.
lacrimal duct irrigator
a 20 gauge, blunt-pointed, straight or curved cannula with a needle attachment so that it can be attached directly to a syringe nozzle.
fossa in the medial wall of the orbital rim which houses the lacrimal sac.
contained in a pad of fat in the dorsolateral part of the orbital cavity and drains into the conjunctival sac via many excretory ducts. The secretion is largely watery tears, but in the pig is mucus. May develop adenitis.
lacrimal gland anomalies
failure of patency of the duct, supernumerary opening of the duct and ductal ectasia recorded.
lacrimal gland atrophy
part of the syndrome of keratoconjunctivitis sicca.
imperforate lacrimal puncta
see imperforate punctum.
the recess between the lids at the nasal commissure of the eye where the tears collect.
contraction of the orbiculari oculi muscle creates pressure on the lacrimal sac which causes tears to drain from the lacrimal lake.
there is one on each eyelid close to the medial canthus. Each drains tears from the conjunctival sac into the lacrimal duct in the same eyelid. The tears then pass to the lacrimal sac and into the nasolacrimal duct. See also punctum.
tear production caused by irritation of the cornea and conjunctiva.
the distended proximal end of the nasolacrimal duct into which the lacrimal ducts empty.
an excavation of the lacrimal bone which communicates with the maxillary sinus in some species.
