Eye Anatomy

Retina

a delicate, light-sensitive layer of tissue at the back of your eye. It functions like the sensor in a digital camera, capturing the visual world and converting light into electrical signals

Choroid

is the highly vascular, pigmented middle layer of the eye, located between the white outer layer (sclera) and the inner light-sensing layer (retina). It plays a critical role in sustaining eye health and vision

Sclera

White part of eye formed from dense connective tissue

Iris

Colored Part

Pupil

Black Part

Rods

Photoreceptor good for seeing motion and in low light

Cones

Photoreceptor good for color and bright light/details

Photoreceptors

Receptors in the eye that respond to light

Proprioceptor

a specialized sensory receptor located within muscles, tendons, joints, and the inner ear. It detects internal stimuli related to movement, muscle tension, and body positioning in space, allowing you to sense where your limbs are without looking at them

Nociceptor

is a specialized sensory nerve ending that detects actual or potential tissue-damaging stimuli. Acting as the body's primary alarm system, these "free nerve endings" respond to extreme temperatures, intense pressure, or chemical signals, transmitting threat signals to the brain to initiate the sensation of pain.

Chemoreceptor

Receptors that react to chemicals including odors taste and concentration of chemicals in the body

Cornea

Transparent extension that sits over the iris and allows light into the eye

Lens

is a clear, flexible located directly behind the iris and pupil. Its primary function is to fine-tune and focus light onto the retina at the back of the eye to create sharp images

Anterior Cavity

Spsce between lens and cornea divided into anterior and posterior chamber

Posterior cavity

Large Cavity in the eye lines posterior to lens and anterior cavity

canal of Schelemm

Vestal that collects Aqueous humor from the anterior chamber of the eye and delivers it to surrounding blood vessels
