LACHRYMAL SAC Meaning and
Definition
-
The lachrymal sac, also known as the lacrimal sac, is a small sac-like structure located in the upper part of the nasolacrimal duct in the eye. It is an integral part of the tear drainage system, which is responsible for draining excess tears from the eye to the nasal cavity, preventing the eye from becoming overly watery or irritated.
The lachrymal sac functions by collecting tears that have flowed through the lacrimal canaliculi, small channels connecting the inner corner of the eye to the sac. It acts as a temporary reservoir for tears before they are further transported into the nasolacrimal duct.
This sac is made up of fibrous tissue and smooth muscle, allowing it to expand and contract as it gathers and transports tears. When a person blinks, pressure is exerted on the sac, pushing the tears into the duct and ultimately into the nasal cavity.
Any blockage or obstruction in the lachrymal sac can result in a condition known as dacryocystitis, characterized by inflammation and infection. Symptoms of dacryocystitis may include pain, redness, swelling, tearing, and discharge from the eye.
Surgical procedures or medical interventions may be required to treat blockages or infections of the lachrymal sac, ensuring the proper functioning of the tear drainage system and maintaining eye health.

Etymology of LACHRYMAL SAC
The word "lachrymal sac" is derived from two main components: "lachrymal" and "sac".
The term "lachrymal" is derived from the Latin word "lacrima", meaning "tear". In Latin, "lacrima" is further derived from the earlier Latin word "lacrima" or "lacruma", which means "tear, drop, or bleeding".
The word "sac" is derived from the Latin word "saccus", which means "bag" or "sack".
When combined, "lachrymal sac" refers to the anatomical structure in the eye responsible for collecting tears. It is known as a sac because of its bag-like shape and its function in storing tears temporarily before draining them into the nasal cavity.
