Question

Quizplus · Accepted Answer

Acetylcholine and GABA are examples of neurotransmitter molecules.

Answer: A
 Cells that nurture and support neurons are called glial cells.

Answer: B
 Sensory neurons receive sensory information and transmit it to the central nervous system.

Answer: C
 Interneurons are neurons that process and transmit information within the central nervous system.

Answer: E
 Motor neurons transmit signals from the central nervous system to muscles or other effectors.

Answer: F
 Active transporters are proteins that use energy to move molecules across a cell membrane.

Answer: G
 The butterfly-shaped interior of the spinal cord is filled with gray matter, which contains clusters of neuron cell bodies.

Answer: H
 Membrane potential refers to the difference in electrical potential between the inside and outside of a cell membrane.

Answer: I
 The resting membrane potential is the membrane potential of a cell at rest, meaning there is no net movement of ions across the membrane.

Answer: J
 Dendrites are the cytoplasmic extensions of neurons that receive and convert chemical signals to electrical signals.

Answer: K
 An action potential is the electrical signal that travels down the axon of a neuron and triggers the release of neurotransmitters.

Answer: L
 Positive feedback is a process in which the output of a system amplifies the input, leading to a larger response.

Answer: M
 The threshold potential is the membrane potential at which an action potential is triggered.

Answer: N
 Electroencephalography (EEG) measures voltage fluctuations in the cerebral cortex to provide information about a person's level of wakefulness.

Answer: O
 Planarians are flatworms that have a simple central nervous system consisting of a cluster of nerve cells called a ganglion.
