434 NORMAL HISTOLOGY AND ORGANOGRAPHY. 



work of condensed fibrous tissue, which gives con- 

 sistency and shape to the lid, and is termed the tar- 

 sal plate, or tarsus. The orbicularis oculi muscle lies 

 beneath the subcutaneous tissue of the outer surface 

 and is composed of voluntary muscle fibers that arch 

 between the angles of the eyelids. 



Fig. 299. Lacrimal and Meibomian glands, the latter viewed from 

 the posterior surface of the eyelids. (The conjunctiva of the upper lid 

 has been partially dissected off, and is raised so as to show the Meibomian 

 glands beneath.) I, Free border of upper, and 2, free border of lower lid, 

 with openings of the Meibomian glands; 5, Meibomian glands exposed, 

 and 6, as seen through conjunctiva; 7, 8, lacrimal gland; 9, its excretory 

 ducts, with 10, their openings in the conjunctival cul-de-sac; II, con- 

 junctiva (Testut). 



The conjunctiva is a mucous membrane that lines 

 the inner surface of the eyelids and is reflected over 

 the front of the eye. Over the cornea it forms the 

 anterior stratified epithelium, and has already been 

 described. The line along which it is reflected on to 

 the globe of the eye is called the fornix. The pal-
