Question
If a stimulus causes impulse conduction (potentials) through all parts of a neuron,, the correct pathway for that conduction is:
Solution
The correct pathway for impulse conduction (potentials) through all parts of a neuron is:
-
Dendrites: The process begins here. Dendrites receive the stimulus and convert it into an electrical signal or impulse.
-
Cell Body (Soma): The impulse then travels to the cell body, which contains the neuron's nucleus. The cell body integrates the information received from the dendrites.
-
Axon Hillock: This is the junction between the cell body and the axon. It is the site where the decision to generate a nerve impulse (action potential) is made.
-
Axon: If the stimulus is strong enough to generate an action potential, the impulse will then travel down the axon. The axon conducts these impulses away from the cell body towards the axon terminals.
-
Axon Terminals: These are small branches at the end of the axon. When the impulse reaches the axon terminals, it causes the release of neurotransmitters.
-
Synapse: The neurotransmitters cross the synapse (the gap between neurons) and bind to receptors on the next neuron, thereby transmitting the signal.
This is the general pathway for impulse conduction in a neuron. However, it's important to note that not all neurons are structured exactly the same, so there may be some variations.
