Question

Quizplus · Accepted Answer

Interneurons receive and send signals from other neurons, allowing for communication between different parts of the nervous system.

Answer: A
 Cells that nurture and support neurons are called glial cells. They do not receive or send signals.

Answer: E
 Motor neurons send signals from the nervous system to muscles or glands, resulting in movement or secretion.

Answer: J
 Dendrites are the cytoplasmic extensions of neurons that receive chemical signals from other neurons and convert them into electrical signals.

Answer: K
 Action potential refers to the electrical signal that travels down the axon of a neuron, allowing for communication between neurons.

Answer: M
 Threshold potential is the minimum depolarization needed to trigger an action potential.

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

Answer: O
 Planarians, which are flatworms, have a simple nervous system consisting of a cluster of cell bodies called a ganglion.
