Match the specialized structures found on neurons to their function. carries information away from the cell body insulates the axon so that nerve impulses can be transmitted quickly contains the control center and powerhouse of the cel receives information and carries it to the cell body

it's D C B A once again having to answer my own questions oh well

As the diagram is not provided, lets have a look at the different parts of a neuron generally.

Explanation:

Dendrites can be described as the parts of the neuron which have a structure resembling like the branches of a tree. The main function of the dendrites is to receive signals from other neurons.

Synapses are the part of the neurons which allows dendrites of different neurons to interact.

Axons are part of the neuron which shaped like a tube. it conducts electrical impulses away from the cell body. They are protected by insulating structures called myelin sheath.

materials water oxygen those are the things i can think of in this moment.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
