Anatomy and Functions of the Eye

The video tutorial provides a detailed guide on dissecting a sheep's eye. It covers the cleaning process, identification of external muscles, and exploration of key anatomical features such as the optic nerve, sclera, and cornea. The tutorial also explains the dissection process, focusing on handling the eye's fluids and examining its layers, including the sclera, choroid, and retina.

What is the first step in preparing the sheep eye for dissection?

• Examining the retina

• Cutting through the sclera

• Cleaning and removing extra tissue

• Identifying the optic nerve

Which muscle is responsible for rotating the eyeball?

• Lateral rectus

• Superior rectus

• Superior oblique

• Medial rectus

What is the function of the sclera in the eye?

• It forms the cornea

• It controls eye movement

• It is responsible for vision

• It produces aqueous humor

Which part of the eye is responsible for forming a clear glass-like structure?

• The cornea

• The retina

• The choroid layer

• The sclera

What is the main characteristic of the aqueous humor?

• It forms the lens

• It is part of the retina

• It is under pressure

• It is thick and viscous

Which fluid is found in the posterior chamber of the eye?

• Vitreous humor

• Aqueous humor

• Choroid fluid

• Retinal fluid

What is the shiny structure found within the eye?

• The retina

• The lens

• The sclera

• The optic nerve

Which layer of the eye is described as dark and brownish?

• Sclera

• Choroid layer

• Retina

• Cornea

What is the function of the retina in the eye?

• It detects light and images

• It controls eye movement

• It forms the cornea

• It produces aqueous humor

What is the ora serrata?

• A part of the retina

• A muscle in the eye

• A fluid in the anterior chamber

• A layer of the sclera
