TARSAL CARTILAGES Meaning and
Definition
-
Tarsal cartilages are specialized structures found in the skeletal framework of the upper eyelids, also known as the tarsi or the tarsal plates. These cartilages are responsible for providing support, stability, and shape to the eyelids. They are composed of a dense connective tissue, primarily made up of collagen fibers.
The tarsal cartilages are located within the upper eyelids, lying parallel to the margins of the eyelid and extending from the medial (inner) corner to the lateral (outer) corner of the eye. They form a semi-rigid structure combined with a slight degree of flexibility, contributing to the overall shape and curvature of the eyelids.
These cartilages serve as an attachment site for various muscles responsible for eyelid movement and control, such as the orbicularis oculi muscle that closes the eye. They help maintain the position and alignment of the eyelashes, preventing them from excessively sweeping into the eye.
Furthermore, tarsal cartilages play a crucial role in the overall protection and lubrication of the eye. They serve as a framework for the meibomian glands, which produce an oily substance called meibum. Meibum helps prevent excessive evaporation of tears and ensures efficient lubrication of the eye, facilitating smooth eyelid movement and reducing friction.
Overall, tarsal cartilages contribute to the structural integrity, function, and appearance of the upper eyelids, playing a pivotal role in the overall health and functionality of the eye.
