Nervous System & Endocrine System

1
Nervous System Endocrine System

• Nervous System Sending messages fast but they
  dont last long
• Endocrine System Sending messages slowly but
  they last a long time
• Types of Neurons
• Parts of the Nervous System
• Glands Hormones of the Endocrine System

3 types Neurons
Types of Neurons
Sensory
Motor
Interneurons

Sensory Neurons

• INPUT From sensory organs to the brain and
  spinal cord

Brain
Sensory Neuron

Spinal Cord
4
Motor Neurons

• OUTPUT From the brain and spinal cord, to the
  muscles and glands

5
Interneurons

• Interneurons carry information between other
  neurons only found in the brain and spinal cord

The Nervous SystemSends messages quickly but
they dont last long.Broken into two parts

• Central Nervous System (CNS)
• Brain and spinal cord
• Peripheral Nervous System (PNS)
• Carries messages to and from CNS

The Nervous System It breaks down into two
parts.

Endocrine SystemUses hormones that travel
through the bloodstream. Takes longer to get
there but lasts a long time
