Which Structure Fills the Lacrimal Groove of the Lacrimal Bone

Question

Which structure fills the lacrimal groove of the lacrimal bone?
A) nasolacrimal duct
B) inferior lacrimal punctum
C) lateral canaliculus
D) lacrimal gland
E) lacrimal sac

Accepted Answer

The lacrimal groove of the lacrimal bone is filled by the lacrimal sac, which is part of the lacrimal apparatus responsible for producing and draining tears. The nasolacrimal duct, inferior lacrimal punctum, lateral canaliculus, and lacrimal gland are also part of the lacrimal apparatus but do not fill the lacrimal groove of the lacrimal bone.
