TEAR GLAND Meaning and
Definition
-
The tear gland, also known as the lacrimal gland, refers to a small, almond-shaped gland located above the outer corner of each eye. It is responsible for the production and secretion of tears, a transparent fluid that lubricates, cleans, and protects the eye surface.
The tear gland consists of several lobes and is composed of numerous small cells that produce tears through a process called lacrimation. Tears are composed of a combination of water, mucus, oil, electrolytes, and antibodies. They play a crucial role in maintaining the health and clarity of the eye by washing away foreign particles, such as dust and debris, and providing essential nutrients and oxygen to the cornea and surrounding tissues.
The tear gland is regulated by the autonomic nervous system, and tear production can be influenced by various factors, including emotional responses (such as crying), environmental conditions (such as wind or dry air), and certain medical conditions, such as allergies or infections. Excessive tearing, known as epiphora, or insufficient tear production, known as dry eye syndrome, can result from abnormalities in the tear gland or associated structures.
In summary, the tear gland is a specialized gland found near the outer corner of the eye responsible for the production of tears, a fluid that provides lubrication, hydration, and protection to the eye surface.

Etymology of TEAR GLAND
The term "tear gland" is derived from Latin and English root words.
The word "tear" comes from Old English "tēar", which can be traced back to the Proto-Germanic word "tahuraz". It is believed to have originated from the Proto-Indo-European root "dakru-", meaning "tear, drop".
The word "gland" comes from the Latin "glandula", which refers to a small organ that secretes substances. This Latin term is derived from the Latin word "glans", meaning "acorn" or "kernel", which is thought to reflect the shape of certain glands.
Therefore, the term "tear gland" combines the English word "tear", referring to the watery secretion from the eyes, and the Latin word "gland", denoting a small organ that produces secretions.
