What is the pathway of information through a neuron?
garik1379 [7]

Answer:

The pathway of information through the neuron is based in the connection of axons with other neurons, favoring the conduction of information from one place to another of the nervous system. The way in which a neuron communicates with another, with a receptor or an effector is called synapse.

Explanation:

Neurons are the specialized cells that allow the function of the nervous system, given by the transmission of information in the form of nerve impulses. The way in which information is transmitted by neurons depends on the connection that exists between neurons, by their axons and dendrites, or between enurons and specialized structures such as receptors and effectors.

When a stimulus reaches a receptor, it connects with the neuron that carries the information by afferent pathway to the central nervous system. Once the information is processed, a response is elaborated that travels through the neurons by efferent pathway to an effector cell.

Synapses are simply the connection that exists between neurons, through their axons, or from these cells to the receptor or effector structures. Synapses are located between one neuronal axon and another, or between axons and receptors or effectors, and occur through electrical signals or chemical mediators called neurotransmitters.

The two planets considered “ice giants” are

I believe its Uranus and Neptune, please tell me if I'm wrong.


Reason: an ice planet is made up of a semi icy surface like perhaps water, oxygen, or any other element stronger than hydrogen. Neptune and Uranus both meet this match, they are made up of elements that are actually stronger than hydrogen.
