Biology- Nervous System

Question 1

Action Potential

Answer 1

Electrical impulses that transmit messages to neurons

Question 2

Neurotransmitters

Answer 2

Chemical messengers that transmit messages to neurons

Question 3

Signaling Molecules in the Nervous System

Answer 3

Apparently nitric oxide functions as a signaling molecule

Question 4

Motor Neurons

Answer 4

Neurons that transmit messages to muscles or glands of the body to exhibit an action of movement

Question 5

Synapse

Answer 5

The site of transmission between electric nerve impulses between two neurons (a neuron and an effector)

Question 6

Receptor Cells

Answer 6

Groups of specialized cells that are able to detect a change in environmental stimulus and stimulate electrical responses when it comes to responding.

Question 7

Sensory Organs

Answer 7

Organs such as …… that have receptors that can respond to certain stimuli

Question 8

Post Synaptic

Answer 8

A neuron that receives a neurotransmitter after it has crossed the synapse and may experience action potential if it’s strong enough

Question 9

Pre Synaptic

Answer 9

A presynaptic neuron is a neuron (nerve cell) that fires the neurotransmitter as a result of an action potential entering its axon terminal.

Question 10

Acetylcholine

Answer 10

Chief neurotransmitter of the parasympathetic nervous system
