Question

Quizplus · Accepted Answer

Voltage difference across a cell membrane is also known as membrane potential.

Answer: I
 The resting membrane potential is the membrane potential of a cell that is not being active or stimulated.

Answer: K
 Action potential is the brief reversal of membrane potential that produces an electrical impulse in a neuron.

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

Answer: J
 Cytoplasmic extension of neurons that convert chemical signals to electrical signals is known as dendrites.

Answer: D
 Acetylcholine and GABA are neurotransmitters that are responsible for transmitting impulses across the synapse.

Answer: F
 Active transporters are a type of protein that uses energy to move molecules across the cell membrane. They help maintain the membrane potential.

Answer: G
 The butterfly-shaped interior of the spinal cord is filled with gray matter, which contains the cell bodies of motor neurons and interneurons.

Answer: O
 Planarians have a simple nervous system made up of a cluster of cell bodies called a ganglion.
