Anatomy Of The Eye And Vision Lab

Front 1

What is the detection of changes in the internal and external environments? Can be conscious and subconscious depending on the destination of sensory information.

Back 1

Sensation

Front 2

The type of sensation that you are consciously aware about taking to the cerebral cortex.

Front 8

The internal surface of the eylids and much of the anterior eyeball is covered with a thin mucous membrane called the...

Back 8

Conjunctiva

Front 9

It is within the eyelids and its oily secretions help to keep the eye lubricated.

Back 9

Meibomian glands

Front 10

Most prominent accessory structures of the eye that produces and drains tears.(it consists of lacrimal gland located in the superolateral orbit and ducts that drain the tears it produces).

Moves the eyeball superiorly and laterally

Back 18

Inferior Oblique

Front 19

A hollow organ with three distinct tissue layers or tunics : Fibrous tunic, Vascular tunic, Sensory tunic.

Back 19

Eyeball

Front 20

Outermost layer of the eyeball consists mostly of dense irregular connective tissue.Its avascular and consist of two parts: Sclera and Cornea

Back 20

Fibrous tunic

Front 21

The white part of the eyeball, that makes up the posterior 5/6 of the fibrous tunic. It is white because of the numerous collagen fibers that contribute to its thickness and toughness.

Back 21

Sclera

Front 22

The clear part that makes up the anterior 1/6 of the fibrous tunic and is one of the refractory media of the eyeball (it bends light coming into the eye).

Back 22

Cornea

Front 23

Also called the uvea, this tunic carries most of the blood supply to the tissues of the eye. It is composed of 3 main parts: Choroid,Ciliary body, and Iris.

Back 23

Vascular Tunic

Front 24

Highly vascular that makes up the posterior part of the vascular tunic.It is brown in color to prevent light scattering in the eye.

Back 24

Choroid

Front 25

Located at the anterior aspect of the eye, made chiefly of the ciliary muscle, which controls the shape of the lens.The muscle attaches the lens via small suspensory ligaments.

Back 25

Ciliary body

Front 26

The ligaments that attaches the muscle to the lens.

Back 26

Suspensory Ligaments

Front 27

The ciliary body is made out of this muscle that controls the shape of the lens.

Back 27

Ciliary muscle

Front 28

It is pigmented and the most anterior portion of the uvea.Consists of muscle fibers arranged around as opening called the pupil. As the fibers contract, the pupil either constricts or dilates.

Back 28

Iris

Front 29

Muscle fibers around an opening in the Iris is called...

Back 29

Pupil

Front 30

This layer consists of the retina and the optic nerve. The retina is a thin, delicate structure that contains photoreceptors called rods and cones.

Back 30

Sensory Tunic

Front 31

Thin delicate structure that contains photoreceptors called rods and cones.

Back 31

Retina

Front 32

Scattered throughout the retina and responsible for vision in dim light and for peripheral vision,

Back 32

Rods

Front 33

Concentrated at the posterior portion of the retina and are found in highest numbers in an area called macula lutea. At the center of the macula lutea is the fovea centralis, which contains only cones. cones are responsible for color and high acuity (sharp) vision in bright light.

Back 33

Cones

Front 34

The highest number of cones are found in this area.

Back 34

Macula Lutea

Front 35

At the center of the macula Lutea and contains only cones.

Back 35

Fovea Centralis

Front 36

There are no rods or cones at the posteriormost aspect of the eyeball where the optic nerve leaves the eyeball. This location is called?

Back 36

Optic disc or Blind Spot

Front 37

Cavities that help to refract light onto the retina.

Back 37

Anterior Cavity and Posterior Cavity

Front 38

The anterior cavity is filled with a watery fluid called

Back 38

Aqueous Humor

Front 39

The posterior cavity contains a thick fluid called

Back 39

Vitreous Humor

Front 40

Allows for precise focusing of light on the retina and divides the eyeball into the anterior and posterior cavities.
