• Lacrimal caruncle located at medial commissure contains sebaceous (oil) and sweat glands o Produces the whitish, oily secretion (Sandman's eye-sand) that sometimes collects at the medial commissure, especially during sleep
• Lacrimal gland is located in orbit above lateral end of eye and is visible through the conjunctiva when the lid is everted o Continually secretes lacrimal secretion (tears) into the superior part of the conjunictival sac through several small excretory ducts, a dilute saline solution containing mucus, antibodies, and antibacterial lysozyme
Infection causes a painful, pus-filled swelling called a sty. Lacrimal apparatus A group of structures that produces and drains lacrimal fluid (tears): lacrimal gland, punctum, canaliculus (canal), sac, and nasolacrimal duct.
• Lacrimal fluid contains mucus, antibodies, and lysozyme, an enzyme that destroys bacterial; thus it cleans and protects the eye surface as it moistens and lubricates o When lacrimal secretion increases substantially, tears spill over the eyelids and fill the nasal cavities, causing congestion and the "sniffles"
medial canthusThe lacrimal caruncle is the small, pink, globular spot at the inner corner, or the medial canthus, of the eye.
The lacrimal caruncle, or caruncula lacrimalis, is the small, pink, globular nodule at the inner corner (the medial canthus) of the eye.
Form the corners of the eyes. The medial commissure contains the lacrimal caruncle. The lacrimal gland is located in the superior and lateral aspects of the orbit of the eye.
The lacrimal caruncle, or caruncula lacrimalis, is a small, pink, globular nodule at the medial canthus of the eye, and it consists of skin, hair follicles, sebaceous glands, sweat glands, and accessory lacrimal tissue.
