Study Notes

Ocular Anatomy & Physiology (Detailed)

Ocular Anatomy (Gross): Examines the eye's major structures and components, including eyelids, eyebrows, lacrimal system, orbit, cornea, conjunctiva, lens, sclera, and uvea(iris, ciliary body, choroid). Anatomical boundaries, layer structure, muscle systems, glands, and blood/nerve supply are highlighted.

Eyelid

Eyelid anatomy: Includes the boundaries, layers, muscles, glands, related blood supply, and innervation.

Eyebrow

Structure and function of eyebrows are discussed.

Lacrimal System

Lacrimal gland structure, accessory glands, tear distribution, and drainage are detailed.
Nasolacrimal canal's role in tear drainage is mentioned.

Orbit

Orbital contents: Bones, foramina, openings, extraocular muscles, and relationships to other orbital structures are discussed, along with blood supply and innervation.

Bones of the Orbit

Anatomical locations, contents of foramina and openings, are outlined.

Extraocular Muscles

Names, origins, insertions, innervation, and relationship with other orbital structures. Blood supply included.

Blood Supply

Overview of blood supply to various eye structures.

Cornea

Normal Dimensions of the cornea are noted.
Epithelial (histology and ultrastructure): Focuses on the cellular structure.
Basal Lamina and Bowman Layer detail of the corneal internal structure.
Descemet Membrane (Posterior Limiting Lamina) and endothelium are described.
