A&P-Ch 11: Nervous system and nervous tissue

Our ______ receive messages and send them to the brain. The brain sends messages to our body on how to respond.

• heart

• lungs

• nerves

This system controls everything you do.

• Nervous system

• Olfactory system

• Respiratory system

• Endocrine system

Without the nervous system, you couldn't

• 1) eyes sense ruler move 2) message sent to brain 3) message sent to muscles 4) muscles contract

The part of the neuron that insulates the axon and increases the speed of the neural message within the neuron.

• Synapse
• Dendrite
• Myelin Sheath
• Axon Terminal Button

This part of the neuron receives chemical messages from the neurotransmitters of other neurons. It is labeled A in the diagram.

• Dendrite

• Axon

• Axon Terminal

• Cell Body

This part of the neuron stores then releases neurotransmitters into the synapse.
