The lacrimal apparatus is the physiologic system containing the orbital structures for tear production and drainage.[1]
It consists of:
- (a) the lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the eye;
- (b) the lacrimal canaliculi, the lacrimal sac, and the nasolacrimal duct, by which the fluid is conveyed into the cavity of the nose, emptying anterioinferiorly to the inferior nasal conchae at the nasolacrimal duct.
- (c) the nerve supply of lacrimal apparatus done by carotid plexuse of nerves along artery internal and external sympathetically but parasympathetic from lacrimal nucleus of the facial nerve
