During the depolarization phase, sodium ions enter the cell through the open ion-channels (Na+ influx).
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina
Axons are part of nerve tissue, which is found within the nervous system. Nerve tissue is composed of neurons that contain axons for carrying nerve impulses.
cell
Nerves transmit messages through electrical impulses known as action potentials. When a nerve is stimulated, ion channels in its membrane open, allowing sodium ions to flow in, which depolarizes the membrane. This change in voltage triggers adjacent ion channels to open, propagating the impulse along the nerve fiber. Once the impulse reaches the end of the nerve, it typically causes the release of neurotransmitters, which transmit the signal to the next nerve or target cell.
Taste buds do not have axons themselves; instead, they contain taste receptor cells that respond to tastants. These receptor cells release neurotransmitters when activated, which then stimulate the afferent nerve fibers associated with the taste buds. These nerve fibers, which do have axons, carry taste information to the brain through cranial nerves, primarily the facial nerve (VII), glossopharyngeal nerve (IX), and vagus nerve (X). Thus, while taste buds don't have axons, they communicate with the brain via the axons of associated nerve fibers.

Bundles of axons are called nerves. Nerves transmit electrical signals between the brain and other parts of the body.
It is called a nerve impulse.

I believe it's Na+

cell
No, axons carry impulses away from the nerve cell body.
Yes. The Retinal Ganglion Cell axons form the optic nerve.
Axons from the olfactory nerve project to the olfactory bulb in the brain. The olfactory bulb processes and relays information about smells to other areas of the brain, such as the olfactory cortex, where scent perception occurs.
Yes
