How Does The Nervous System Work? Neurons and Neurotransmitters

The video explores the nervous system, highlighting its protective and arousal functions. It explains the roles of sensory, relay, and motor neurons in transmitting information and responding to stimuli. The process of neural response to heat is detailed, followed by an examination of neuron structure, including axons, dendrites, and synapses. The video concludes with a call to action for viewer engagement.

What is the primary function of the nervous system as described in the video?

• To circulate blood

• To digest food

• To protect the body and facilitate quick responses

• To produce hormones

Which type of neuron is responsible for carrying information from the senses to the spinal cord?

• Relay neurons

• Interneurons

• Motor neurons

• Sensory neurons

In the example of touching a hot stove, what role do motor neurons play?

• They deliver the message to muscles to pull back the hand

• They transmit signals within the brain

• They select the appropriate response

• They detect the heat

What is the function of the myelin sheath in a neuron?

• To slow down electrical impulses

• To store neurotransmitters

• To connect neurons directly

• To speed up the journey of electrical impulses

How do neurotransmitters facilitate communication between neurons?

• By storing electrical impulses

• By creating new neurons

• By directly connecting axons and dendrites

• By diffusing across the synapse and binding to receptors
