Holt Nervous and Endocrine System Review

Two neurons connect at a place called a _______.

• synapse

• stimulus

• cerebrum

• cell body

Physical injuries, like a major car accident, can be very dangerous to nervous system health. How?

• the nerves will communicate slower

• pain receptors activate during physical injuries

• damaged nerves cannot send or receive signals

• the driver will be very upset about their destroyed car

After seeing a moth, a frog uses its tongue to catch it. This is an example of:

• gathering information

• responding to a stimulus

• maintaining homeostasis

• collecting waste

An impala's heart rate and adrenalin levels increase when trying to escape a cheetah. This is an example of:

• gathering information

• responding to a stimulus

• maintaining homeostasis

• collecting waste

What are the two parts of the nervous system?

• Central nervous system and peripheral nervous system

• Peripheral nervous system and Overall nervous system

• Central nervous system and West nervous system

• The nervous system does not have two parts.

This releases neurotransmitters which are sent into the synaptic gap

• axon

• axon terminal

• gene

• neuron
