15 Superficial lamina of levator tendon.
Lamina superficialis. It passes between the tarsus and orbicularis oculi to insert into the subcutaneous connective tissue of the upper eyelid. It is so broad that it extends mainly laterally to the wall of the orbit. A
16 Deep lamina of levator tendon. Lamina profunda. It inserts into the upper margin and the anterior surface of the tarsus. A
18 Periosteum of orbit. Periorbita. It is delicate and fused solidly to the bone at the inlet and outlet of the orbit. Anteriorly, it is continuous with the adjacent periosteum, posteriorly with the dura. A
19 Orbital septum. Septum orbitale. Connective tissue septum partly reinforced by tendon. It passes from the orbital margin below the orbic-ularis oculi to the external margins of the tarsi and forms the anterior end of the orbit. A
20 Muscular fasciae. Fasciae musculares. Sheaths ofTenon's capsule enveloping the tendons and muscular bellies of the 6 extrinsic ocular muscles. A
21 Tenon's capsule (fascia bulbi). Vagina bulbi. Connective tissue gliding membrane between the eyeball and orbital fat. It is fused to the sclera posteriorly at the optic nerve. Anteriorly it ends beneath the conjunctiva. It is separated from the sclera primarily by the episcleral space. A
22 Episcleral space. Spatium episclerale [[ intervaginale]]. Gliding space between the eyeball and Tenon's capsule. It is traversed by long, delicate connective tissue fibers. A
23 Orbital fat body. Corpus adiposum orbitae. Adipose tissue fills the spaces around the ocular muscles, the eyeball and the optic nerve and is bordered anteriorly by the orbital septum. A D

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
