Structure of Eye Flashcards
List the main structures of the eye
(Iris, Retina, Cornea, Pupil, Optic Nerve, Lens)
How does the Iris relate to the stimulus response model?
The iris’s response to changes in light levels is an example of the stimulus-response model in action. The stimulus (light entering the eye) triggers a response in the form of the iris adjusting the size of the pupil to regulate the amount of light that reaches the retina. This response is automatic and occurs without conscious thought or decision-making.
How does the retina relate to the stimulus response model?
The response of the retina to changes in light levels is an example of the stimulus-response model in action. The stimulus (light entering the eye) triggers a response in the form of the photoreceptor cells in the retina detecting the light and converting it into neural signals that are transmitted to the brain. This response is automatic and occurs without conscious thought or decision-making.
How does the Cornea relate to the stimulus response model?
The response of the cornea to incoming light is an example of the stimulus-response model in action. The stimulus (light entering the eye) triggers a response in the form of the cornea bending or refracting the light to focus it on the retina. This response is automatic and occurs without conscious thought or decision-making.
How does the Pupil relate to the stimulus response model?
The response of the pupil to changes in light levels is an example of the stimulus-response model in action. The stimulus (light entering the eye) triggers a response in the form of the pupil adjusting its size to control the amount of light that enters the eye. This response is automatic and occurs without conscious thought or decision-making.
How do the Optic Nerves relate to the stimulus response model?
The response of the optic nerve to visual stimuli is an example of the stimulus-response model in action. The stimulus (visual information from the retina) triggers a response in the form of the optic nerve transmitting the neural signals to the brain for processing. This response is automatic and occurs without conscious thought or decision-making.
How does the Lens relate to the stimulus response model?
The response of the lens to visual stimuli is an example of the stimulus-response model in action. The stimulus (incoming light) triggers a response in the form of the lens changing shape to focus the light onto the retina. This response is automatic and occurs without conscious thought or decision-making.
