Stimuli alter the activity of excitable sensory cells and generate action potentials via _____.
vlada-n [284]
TRANSDUCTION. This refers to the stimulus being converted into an action potential which is then transmitted in the axons going to the central nervous system. This usually starts at the receptor cell. The stimulus change the electrical potential across the cell membrane. This will result in depolarization of the membrane which allow the action potential to be transmitted towards the brain where the electrical impulse is integrated. This usually happens in sensory cells in the body such as vestibular apparatus, olfactory cells, the retina and even the nerve endings alls over our body.

Millions of sperm are needed because most of them don't make it up there to the egg. So i'm thinking maybe more sperm means the higher chance of the egg being fertilized.<span />

The typical state of a neuron is the _____ potential, but when electrical signals stimulate it to its threshold, the _____ is im
Fudgin [204]

<u>Answer:</u>

The typical state of a neuron is the<u> resting potential</u>, but when electrical signals stimulate it to its threshold, the <u>action potential</u> is immediately observed.

<u>Explanation:</u>

The capacity for rest shows what occurs when a neuron is at rest. A capacity for action takes place when a neuron passes information down an axon, far from the cell body. When depolarization exceeds approximately -55 mV a neuron can activate the capacity for action.

Sodium-potassium valves start moving two potassium ions within the cell as three sodium ions are poured out to keep the negatively charged membrane within the cell; this keeps the resting potential in place.
