Not sure, since I'm working on the same assignment, but I think it is ganglion cells.
the gagliano cell axons make a right angle turn at the inner face of the retina then leave the posterior aspect of the eye as the thick optic nerve. page 553 marieb&hoehn
axons from the ganglion cells run along the internal surface of the retina and converge posteriorly to form the optic nerve. pg 489 human anatomy 5th ed marieb,mallatt,wilhelm

How does the message from the nerve cells in the eyes reach the brain?
Through electrical impulses travelling along nerves and neurons at speeds of over 120 mph. They travel from the occipital nerves in the backs of the eyes to the occipital lobe, which is located in the back of your brain.
What is an analogy for a cell compared to a city?
A cell makes up a body as a city makes up a state.
What two type of cell populations make up neural tissue?
Sensory (receptor), motor (effector), and intermediate (relay) nuerones. They have functions of transmitting impulses to nerve cells, from nerve cells to effector muscles, and from one nerve cell to another respectively.
Basic unit of structure of the nervous system?
The basic structural unit of the nervous system is a neuron, or nerve cell. Neurons are made up of a soma, or body, an axon, and dendrites.
What is the smallest unit that makes up a hair?
a cell
What is made up of special nerve cells that are connected to the rods and cones?
the answer to that questions is the optic nerve

What are the special nerve cells that make up the back wall of the eyeball?
optic nerve cells.

When fluid builds up in the eye and causes damage to the optic nerve and the loss of vision the disorder is called?
High optic nerve pressure is associated with high CSF (cerebral spinal fluid) in the brain. The condition has two names: idiopathic Intercranial hypertension, or Pseudotumor Cerebri. When the CSF level in the brain spikes, it causes fluid to back up an build up in the optic nerves. Pressure in the optic nerve and in the brain can be decreased with diuretics(such as Diamox). Pressure in the brain can be relieved by spinal taps, or a surgical procedure where a shunt is inserted into the brain. The fluid in the optic nerves can be decreased by a surgical procedure called Optic Nerve Sheath Fenestration.
What does the optic nerve look like?
It is made up of about 1 million small individual thread-like nerve fibers that come from the retina.
Where does the optic nerve end up after it leaves the eye?
At the back of the brain where the occipital lobe is located.
What happens when an image forms on the retina?
Each light-sensitive receptor cell generates a signal in its attached optic nerve fibre, for transmission to the brain where the combined signals are processed to build up the image itself in our minds.
Is a nerve a cell?
Nerves are made up of cells.
What does the optic nerve in the human eye do?
The optic nerve is a bundle of tissue that transmits the signals generated from the eye to the brain. In essence, the optical nerve is the connection between the eye and the brain. It consists of a grouping of over one million nerve fibers, although the tissue of the optic nerve is actually more closely related to brain tissue than to nerve tissue - hope its good enough ^.^ c": c(:
A structure which can change light into nerve impulses is the a.lens b.optic nerve c.cone cell d. brain?
c. cone cell........... cone cells are part of the retina which makes up the back and sides of the main chamber of your eye. they are a photreceptor responsible for color and high vision acuity. they convert light energy into nerve impulses
What is the cell that make up the brainspinalcordand nerves?
The cell that makes up the brain and spinal cord is mainly the neuron (nerve cell). There are also other types of cells called glial cells, and within glial cells, there are astro glia, oligodendroglia and micro glia.
