The optic nerve is composed of axons of?
The optic nerve is composed of axons of retinal ganglion cells. These ganglion cells transmit visual information from the retina to the brain for processing.
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
The neurotransmitters of a neutron enable a nerve impulse to do what?
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
What happens to a muscle when an electrical impulse from a nerve stops?
When the electrical impulse from a nerve stops, the muscle relaxes and returns to its resting state. This is because the nerve impulse initiates the release of calcium ions in the muscle cells, leading to muscle contraction. When the nerve impulse stops, the calcium ions are reabsorbed, causing the muscle to relax.
Which is ganglion of lacrimation?
The pterygopalatine ganglion is responsible for lacrimation (tear production). It receives preganglionic parasympathetic fibers from the facial nerve (CN VII) via the greater petrosal nerve and contributes to the regulation of tear secretion.
What type of nerve is the optic nerve?
ganglion cells
What is the part of the eye that converts light energy to electricity into electrical signals?
First you must understand how light is transferred into an image by the eye. Located in the retina at the back of the eye are millions of photoreceptors. The way I understand them to work is they are constantly blocking any impules from themselves to the next connection, ganglions. When light hits these potoreceptors, the impulse is released, travels through the ganglion, and then is transmitted to the actual optic nerve. So according to this question, the photoreceptors are the trigger of light to impulse, but the answer to your question is the ganglion that transmitts the impulse to the optic nerve.

What is quicker a nerve impulse or a hormone?
nerve impulse

The optic nerve is composed of axons of retinal ganglion cells. These ganglion cells transmit visual information from the retina to the brain for processing.
What is the path of light from the outside of the eye to the retina?
Light enters the eye through the cornea, then passes through the pupil and the lens. The light is focused and projected onto the retina at the back of the eye where it is processed by the photoreceptor cells and transmitted to the brain via the optic nerve.
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
Do the axons of retinal ganglion cells form the optic nerve?
Yes. The Retinal Ganglion Cell axons form the optic nerve.
What is a nervous system word that starts with g?
Ganglion cells A ganglion is a biological mass of nerve cells.
How does a nerve impulse follow all or nothing principle?
How does a nerve impulse follow the all-or-nothing principle???
Is there a difference between ganglion and ganglia?
Yes, there is a difference between ganglion and ganglia. Ganglion refers to a single nerve cell cluster, while ganglia is the plural form, referring to multiple nerve cell clusters.
What cells form the optic nerve?
Retinal ganglion cells.
