Nerves are generally located where in the body?

• Only in the core areas

• Everywhere throughout the body

• Only in the brain

• Only in the spinal cord

You get a mosquito bite that itches.

Place the nerve signal events in order.

• Your sensory nerves notice the itch

• Your sensory nerves send a message to the brain

• Your brain sends a signal to the muscles to scratch

• You scratch the bite mark

• Your brain gets the message and decides what to do

One structure found in a nerve cell is the long reaching arm or tentacle known as an axon.

How does this structure help the nerve cell do it's job?

• The axon stores nutrients for the nerve cell.
• The axon helps the nerve cell maintain its shape.
• The axon absorbs signals from other cells.
• The axon sends signals along it to other cells.

There are 3 main kinds of nerve cells. Match each type to it's job.

• Motor Neuron

• Sends messages from the brain to muscles, which cause parts of the body to move. 

• Interneuron

• Detects light, sound, odor, taste, touch, and heat. Then sends signals about these inputs to the brain.

• Sensory Neuron

• Helps to move messages between different nerves in your body.

Some things you do are voluntary, you decide to do it consciously. However there are also actions your brain does for you automatically without you thinking about it. Sort each action into the correct category.

Groups:

(a) Voluntary

,

(b) Automatic

• Telling your stomach to digest food

• Breathing all day long

• Dancing along to a song

• Taking a drink of water

• Talking with a friend

• Keeping your heart beating

During the perception deception movie we learned that . . .

• You see and hear everything around you EXACTLY as it is

• Illusions like yanny/laural and the dress show us where our brain fills in the gaps in our senses

• Our senses cannot reliably tell us anything about the world around us

• Illusions like yanny/laural and the dress show us how our brains are all exactly the same

Almost all animals, except for super simples ones like sponges, have a . . .

• Brain

• Nervous System

• Spinal cord

• Heart System

Our nervous system is divided into 2 main parts.

Be sure to mark both correct answers.

• Central nervous system (CNS)

• Peripheral nervous system (PNS)

• Cerebral nervous system (CNS)

• Sympathetic nervous system

  (SNS)

• Autonomic nervous system (ANS)
