What does each part do?

The brain makes the inputs, the spine moves to the other nerves, the nerves execute

the actions.

How are the parts connected?

Each neuron receives signals from either other neurons or from the spinal cord. Each neuron can be traced back to the spine. The spine connects to the brain directly via

the brain stem.

What functions does this system execute?

● Sensory

● Motor functions (i.e. bending your fingers).

● Integration

What other systems does this system interact with?

● endocrine system

Can the COVID-19 virus infect this system

● No, COVID-19 only affects the respiratory system because it causes coughs, shortness of breath, and sneezing.

What are the life-sized dimensions of each organ● The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18

in) in men and around 43 cm (17 in) long in women. The diameter of the spinal cord ranges from 13 mm (1⁄2 in) in the cervical and lumbar regions to 6.4 mm (1⁄4 in) in the thoracic area.

Add 5 fun facts about your system.1. biologists have discovered that nerve cells probably can regenerate. They just don't do it very much or very fast.

2. There are two types of cells in your brain, neurons and glial cells (glia - Greek word for glue).

3. Neurons have special types like sensory neurons which send signals regarding the five senses and motor neurons which carry signals around the body & away from the brain.

4. When you’re young and get a brain injury, other parts of the brain can take over for that purpose until it regenerates.

5. A part of the peripheral nervous system called the autonomic nervous system controls many of the body processes you almost never need to think about, like breathing, digestion, sweating, and shivering.
