What are the 3 Parts of the Brain?
Hindbrain, Midbrain, Forebrain
What are the two parts of the central nervous system?
Brain and spinal cord

What happens if you fracture or break your spine?
interrupts the signals from the brain to the body and vice versa.
Yes
What does the Spinal Cord Do?
Sends Motor commands to the body and Sensory information to the brain

What Are Motor Neurons?
Motor Neurons send messages to your brain about how you move your muscles
What happens when people have Alzheimer’s Disease?
The nerve cells in your brain die
What happens when Motor Neurons are damaged?
can lead to instability, muscle pain, weakness, and the inabilty to do physical movements.
What does the HindBrain do?
The hindbrain regulates breathing and heart rate, and coordinates signals with the rest of the brain.
What do internurons do in the brain?
Interneurons connect sensory and motor neurons and enable the brain to do complex actions
What are Sensory Neurons?
