Answer 36

Neural activity based on signals shown through blood-oxygen levels

Question 37

Dendrites

Answer 37

Receive impulses or messages

Question 38

Cell body

Answer 38

Integrates signals from dendrites and has nuclear, gives cell life

Question 39

Axon

Answer 39

Energy moves from cell body through axon to deliver the message

Question 40

Axon terminals

Answer 40

Release neurotransmitters to stimulate dendrites on next neuron

Question 41

Myelin sheath

Answer 41

Substance that protects axons and speeds up transmission of impulses

Question 42

Nodes of ranvier

Answer 42

Areas axon isn’t covered by sheath and speeds up neural impulses

Question 43

Synapse

Answer 43

-Space between two neurons that neurotransmitters are passed between -nerve impulses only go one direction
