HONDROS BIO 117 NERVOUS
SYSTEM QUESTIONS & 100%
CORRECT ANSWERS
Neuron - correct answer ✔✔communicates with other cells and can be communicated with
Central nervous system - correct answer ✔✔brain and spinal cord
Peripheral nervous system - correct answer ✔✔cranial and spinal nerves
Neuroglia - correct answer ✔✔provides support, protection, and nourishment for neurons
Dendrites - correct answer ✔✔receive signal from other neurons with receptors
Cell body (soma) - correct answer ✔✔organelles
Axons - correct answer ✔✔sends signals
Many axons in our nervous system are covered with? - correct answer ✔✔Myelin sheath
What is the function of myelin sheath? - correct answer ✔✔Sends signals faster
Axon terminals - correct answer ✔✔stores neurotransmitters and is at the very end of the axon
, Neurotransmitters - correct answer ✔✔special proteins made by neurons that are used to
communicate their signal from one neuron to the next
Sensory neurons - correct answer ✔✔sends information from the stimulus towards cns
Interneuron - correct answer ✔✔receives information from a sensory neuron and analyzes the
information
Motor neuron - correct answer ✔✔takes information to the appropriate effector
Resting potential - correct answer ✔✔the neuron is at rest and the cell is negatively charged
What is the main intracellular ion? - correct answer ✔✔Potassium
What is the extracellular ion? - correct answer ✔✔Sodium
Depolarization - correct answer ✔✔the phase when the neuron is stimulated and sending signal
to the next neuron
What happens when action - correct answer ✔✔potential rushes into the cell?-the cell
becomes depolarized and the electrical signal is sent down the axon
Repolarization - correct answer ✔✔getting the neuron back to resting potential by stoping
sodium from coming in, allow potassium to leak out
Sodium/potassium pump - correct answer ✔✔gets sodium out of the cell and potassium back
into the cell
