What does the optic nerve control?
Doesn't control anything. It carries information from the retina, at the back of the eye, to the visual cortex, at the back of the brain.
Which cells comprise the chain of five cells in the visual pathway beginning with the photoreceptor cell of the retina?
retina-optic nerve-optic chiasma synapse at thalamus-optic radiation-optic cortex
What is the difference between thalamus and hypothalamus?
The hypothalamus is in control of homeostasis and the process of negative feedback (for example: blood solute level and body temperature). This is in contrast to the thalamus which is a sort of relay organ of the brain designed to transmit the sensory electrical pulse onto the more specialised organ (e.g. retina (eye) --> optic nerve --> thalamus --> primary visual cortex --> visual association cortex). It is slightly large and positioned above of the hypothalamus.
Encoded information travels along the optic nerve to the?
The optic nerve transmits visual impulses from the retina to the brain.
The brain region receives Visual impulses?
the eye receives visual images from our surroundings, these images are received by the cones and rods which are on the retina which is found in the eye, the images are translated (by the cones and rods) and sent as impulses to the brain through the optic nerve, the brain is then able to inter-prate these impulses into images we see.
What is the function of the optic in the eye?
The optic disc in the human eye is the part of the eye that is connected to the retina and carries visual information to the thalamus and other parts of the brain.
What type of sensory information travels from the retina through the thalamus to the visual cortex?
smell
What is the definition of optic nerve?
Each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye.
What is lgn referr to in the eye?
This stands for lateral geniculate nucleus. It is in the thalamus and is the primary relay centre for visual information from the retina in the eye.
How does the optic nerve work?
The optic nerve is a group of nerve fibers that function to provide vision. The optical never works by transferring electrical impulses to the brain from a part of the eyes known as the retina.
What is the function of lateral geniculate nucleus?
The lateral geniculate nucleus (LGN) is the primary relay center for visual information received from the retina of the eye. The LGN is found inside the thalamus of the brain.
What does the optic nerve control?
Doesn't control anything. It carries information from the retina, at the back of the eye, to the visual cortex, at the back of the brain.
Which cells comprise the chain of five cells in the visual pathway beginning with the photoreceptor cell of the retina?
retina-optic nerve-optic chiasma synapse at thalamus-optic radiation-optic cortex
Is it optic nerve carries the message into the brain from the retina?
Yes?
What is the nerve that takes a picture on the retina and carries it to the brain?
Optic
What is the extra layer of reflecting cells behind the retina?
The choroid layer lies behind the retina and in front of the sclera. It carries oxygen and other necessary nourishment to the retina.
What is the function of the optic disk in the eye?
Optic disc:The optic disc is also called the blind spot. There are no receptors in this part of the retina. This is where all of the axons of the ganglion cells(last neurons before optic nerve) exit the retina to form the optic nerve.
