What is the cord at the back of the eyeball?
The optic nerve is the cord at the back of the eyeball, it also carries impulses from the eye to the brain.
3 Describe how would you identify the optic nerve in the dissection?
To identify the optic nerve in a dissection, locate the eyeball and trace the nerve posteriorly, towards the brain. The optic nerve is typically found at the back of the eyeball, exiting through the optic disc in the retina. It appears as a white, cylindrical structure that connects the eye to the brain.
How do you numb your hand nerve cells?
Rub it against something warm, generate heat to get back the circulation.
Does the retina of the human eye cover the whole of the inside or just the back?
The retina of the human eye covers only the back of the eye, lining the inner surface of the eyeball. It contains light-sensitive cells that convert light into electrical signals, which are then transmitted to the brain via the optic nerve for visual processing.
What is the name of the membrane of the eye that contains nerve cells?
The membrane of the eye that contains nerve cells is called the retina. It is a thin layer of tissue located at the back of the eye and is responsible for converting light into neural signals, which are then sent to the brain for processing. The retina contains photoreceptor cells known as rods and cones, which are essential for vision.
What is the sight nerve?
The sight nerve is called the optic nerve, and goes from the back of the eyeball to the brain.
What is the back of the eye filled with nerve endings?
The retina is the structure at the back of the eyeball that is filled with nerve endings.
What is the cord at the back of the eyeball?
The optic nerve is the cord at the back of the eyeball, it also carries impulses from the eye to the brain.

The macula is at the center of what thin layer of neural cells that lines the back of the eyeball?
Retina
The screen on which the image in formed in the eye is called?
The screen on which the image is formed in the eye is called the retina. The retina contains special cells called photoreceptors that convert light into electrical signals, which are then sent to the brain for processing.
Where does the optic nerve enter the eye?
The optic nerve enters the eye at the back of the eyeball through an opening called the optic disc. This area is also known as the blind spot because it lacks light-sensitive cells (rods and cones) that are present in other parts of the retina.
How does the message from the nerve cells in the eyes reach the brain?
The message from nerve cells in the eyes is transmitted through the optic nerve to the brain. The optic nerve carries this visual information to the brain's visual cortex, where it is processed and interpreted.
Individual nerve cells are called?

What is the back of the eyeball called?

Can you scratch the back of your eyeball?
Ew! No!
What are the nerve cells in the brain and the spinal cord called?
