The lacrimal gland is a compound tubuloacinar gland, it is made up of many lobules separated by connective tissue, each lobule contains many acini.The acini composed of large serous cells which, produce a watery serous secretion, serous cells are filled with lightly stained secretory granules and surrounded by well-developed myoepithelial cells and a sparse, vascular stroma.
The blood supply to the lacrimal gland is provided by the ophthalmic artery with its branch - the lacrimal artery, while the venous blood is drained from this region via the superior ophthalmic vein. The lacrimal system is made up of a secretory system, which produces tears, and an excretory system, which drains the tears.
The lacrimal artery supplies the lacrimal gland, the eyelids and conjunctiva, and the superior rectus muscle and lateral rectus muscle. [6]Recurrent meningeal branch. A recurrent meningeal branch may sometimes arise from the lacrimal artery to pass backwards, exiting the orbit through the lateral part of the superior orbital fissure to reach the dura mater.
The next branch of the ophthalmic artery is the lacrimal artery, one of the largest, arises just as the OA enters the orbit and runs along the superior edge of the lateral rectus muscle to supply the lacrimal gland, eyelids and conjunctiva.
The lateral palpebral arteries are the two large branches of those terminal branches of the lacrimal gland that supply the eyelid, with one lateral palpebral artery supplying one eyelid or the other. They pass medial-ward within the eyelid.
It is a j-shaped gland; The lacrimal canaliculi, the lacrimal sac, and the nasolacrimal duct, by which the fluid is conveyed into the cavity of the nose, emptying anterioinferiorly to the inferior nasal conchae from the nasolacrimal duct; The innervation of the lacrimal apparatus involves both the a sympathetic supply through the carotid plexus ...
The Troubled-Teen Industry Has Been A Disaster For Decades. It's Still Not Fixed.
The lacrimal nerve branches from the ophthalmic nerve immediately before traveling through the superior orbital fissure to enter the orbit. [citation needed]At the superior portion of the lateral wall of the orbit, it also receives a secretomotor [2]: 495 communicating [2]: 402 parasympathetic [3] branch from the zygomaticotemporal nerve [2]: 495 for the lacrimal gland.
