Caruncula lacrimalis
Caruncula Lacrimalis
The Caruncula Lacrimalis (pronunciation: kah-runk-yoo-lah lak-ri-may-lis) is a small, pink, globular nodule at the inner corner of the eye. It is made of skin covering sebaceous and sweat glands.
Etymology
The term "Caruncula" is derived from the Latin word 'caruncula', which means 'small piece of flesh', and "Lacrimalis" is derived from the Latin word 'lacrima', meaning 'tear'. Thus, the term 'Caruncula Lacrimalis' refers to a small piece of flesh related to tears.
Function
The Caruncula Lacrimalis contains sweat and oil-secreting glands, and is thought to aid in the eye's tear drainage system. It also helps to protect the eye from dust and other foreign particles.
