Schlemm's canal
Schlemm's Canal
Schlemm's Canal (pronounced: /ʃlɛmz kəˈnæl/), also known as Schlemm's Canal or Canalis Schlemmi, is a circular lymphatic-like vessel in the eye that collects aqueous humor from the anterior chamber and delivers it into the bloodstream. The canal is named after the German anatomist, Friedrich Schlemm, who discovered it in 1830.
Etymology
The term "Schlemm's Canal" is derived from the name of its discoverer, Friedrich Schlemm (1795–1858), a German anatomist. The word "canal" comes from the Latin canalis meaning "channel, groove, or pipe".
Function
Schlemm's Canal plays a crucial role in the drainage of the aqueous humor from the anterior chamber of the eye. It helps maintain the intraocular pressure within the normal range, thus preventing conditions like glaucoma.
Anatomy
Schlemm's Canal is a circular channel that lies at the junction of the cornea and the sclera, also known as the limbus. It is approximately 10 mm in diameter and is lined by endothelial cells. The canal is connected to the anterior chamber of the eye through a series of tiny pores known as trabecular meshwork.
