13-4 Neurons (Nerve Cells)

Which part of the neuron detects/receives electrical and chemical "information" from other cells?

• dendrites

• the axon

• soma

• axon terminals

Which part of the neuron houses the cell nucleus and other common organelles?

• the axon

• the dendrites

• the soma

• the myelin sheath

Which part of the neuron is the long extension that carries/ transmits electrical "information"?

• the dendrites

• the soma

• the axon

• the nodes of ranvier

Since the neurotransmitter is a signal transmitted between cells, it is part of a general category of molecules known as

• receptors

• ligands

• enzymes

• hormones

At the synapse, which part of the nerve cell is releasing the neurotransmitter (sending the signal)?

• the dendrite

• the axon terminal

• the axon hillock

WITHIN ONE neuron, information travels from 

• the dendrite to the axon terminal

• the axon terminal to the dendrite

BETWEEN DIFFERENT neurons, information travels from 

• the axon to the dendrites

• the dendrites to the axon

What type of signaling occurs when the neurotransmitter diffuses across the synaptic cleft from one neuron to the next?

• autocrine

• paracrine

• juxtacrine

• endocrine
