Mid Year Biology Assessment

The column of tissue connecting the brain to nerves is...

• spinal cord

• central nervous system

• peripheral nervous system

• All of the above

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels. 

• Positive Feedback Response

• Negative Feedback Loop

What is the function of the nerve cells?

• They are responsable of your defense mechanism.

• They transmit signals or messages to other neurons, organs or glands.

• They transmit substances to your endocrine system to produce hormones.
