Nervous system signals are transmitted electrically along individual neurons, but neurons are separated from each other by a tiny gap. Chemical messengers called neurotransmitters cross the gap between neurons. Neurotransmitters fit into...

Nervous system messages are sent as electrical signals along the length of axons and dissolved salts are important for electrical signaling in cells. In this instructional activity learners are introduced to this concept by creating an...

When one thinks of neurotransmitters, zombies do not usually come to mind. In this lesson, students take on the roles of neurons and must transmit messages. This will help them to appreciate the importance of properly functioning...
