NERVOUS SYSTEM

WHAT IS THE NERVOUS SYSTEM?

• It is a network of organs and nerves that sends signals throughout the body and controls everything we do

• It isn't a network of organs and nerves that sends signals throughout the body and it does not control everything we do

• It is a computer with red and green lines connected in all of our body

PARTS OF THE BRAIN

• 1. CEREBELLUM, 2. CEREBRUM, 3. BRAIN STEM

• 1. CEREBRUM, 2. CEREBELLUM, 3. RAIN STEM

CEREBRUM CONTROLS...

• Voluntary actions such as run, jump, dance, etc.

• involuntary actions such as the heartbeat, breath, blink

• coordination and balance

CEREBELLUM CONTROLS...

• Voluntary actions such as run, jump, dance, etc.

• involuntary actions such as the heartbeat, breath, blink

• coordination and balance

BRAIN STEM CONTROLS...

• Voluntary actions such as run, jump, dance, etc.

• involuntary actions such as the heartbeat, breath, blink

• coordination and balance

The nervous system is divided into two parts:

• central nervous system and peripheral nervous system

• motor nerves and sensory nerves

• sensory neuron and motor neuron

STRUCTURE OF A NEURON

• 1. DENDRITE, 2. AXON

• 1. AXON, 2. DENDRITE

• 1. NERVE, 2. TAIL

There are three main types of neurons.

• sensory neurons, interneurons, motor neurons.

• spinal neuron, sensory neuron, motor neurons

• brain neuron, arm neuron, motor neuron
