Medial palpebral ligament
Medial Palpebral Ligament
The Medial Palpebral Ligament (pronunciation: me-dee-al pal-pee-bral lig-a-ment) is a significant anatomical structure in the human eye. It is also known as the medial canthal tendon.
Etymology
The term "Medial Palpebral Ligament" is derived from three words. "Medial" is a term used in anatomy to refer to the middle or towards the midline of the body. "Palpebral" is derived from the Latin word "palpebra," which means eyelid. "Ligament" is derived from the Latin word "ligamentum," which means band or tie, referring to the band of fibrous tissue connecting two structures in the body.
Anatomy
The Medial Palpebral Ligament is a fibrous band that connects the tarsal plates of the upper and lower eyelids to the medial wall of the orbit. It is divided into two parts: the superior and inferior, which are attached to the frontal process of the maxilla and the lacrimal bone, respectively.
Function
The primary function of the Medial Palpebral Ligament is to provide stability to the medial (inner) corner of the eyelids, ensuring they remain in close apposition to the globe of the eye. This is crucial for the proper functioning of the lacrimal apparatus, which is responsible for the production and drainage of tears.
Related Terms
- Tarsal plates: These are thick, dense connective tissue found within the eyelids, providing them with form and rigidity.
- Maxilla: The maxilla is the upper jawbone in humans and most other animals.
- Lacrimal apparatus: This is the physiological system containing the orbital structures for tear production and drainage.
