Sense of Vision and Eyeball Anatomy

Flashcards covering the anatomy of the eye, visual photoreceptors, ocular fluids, and related structures.

Organ of vision components

eyeballs, lacrimal apparatus, and ocular muscles.

Sclera

Layer of the eyeball that contains extraocular muscles controlling eye movement.

Coroides

Its pigment absorbs luminica energy

Retina

Eyeball layer containing photoreceptor cells (rods and cones) that convert light into visual information.

Conos

Nos permiten ver a color, hay conos sensibles al rojo, azul y al verde, convierten la luz en imagen.

Bastones

Nos permiten ver en condiciones de poca luminosidad, perciben escala de grises

Cornea

capa transparente, protege el globo ocular y tiene la cámara anterior que contiene el humor acuoso, su función es lubricar el cristalino, la cámara posterior contiene el humor vitreo, este ayuda a mantener la fuerza de tensión del ojo.

Humor acuoso

Fluid contained in the anterior chamber of the eye whose function is to lubricate the crystalline lens.

Vitreous humor

Fluid contained in the posterior chamber of the eye that helps maintain the tension force of the eye.

Ciliary body

Structure that modifies the shape of the crystalline lens for focusing and secretes aqueous humor.

Iris

Structure responsible for eye color.

Pupila

Aperture that dilates or contracts depending on the stimuli it receives.
