Biology 067: Quiz/Assignment 10c: Nervous System – Peripheral Nervous SystemWork with a partner to do the following:1) With your partner make a rough drawing of the spinal cord and brain. Talk about the 2 types of nerves in the

PNS (cranial and spinal); where they would branch from, areas they may enervate. (Accuracy is not needed – however, you should talk about how many of each type - you can use the diagram on the back to help you)

2) Using the drawing below, describe the path way of the Somatic Nervous System of the PNS and describe to each other what a reflex arc is.

3) Use the diagram and your notes to describe the

motor nerves of Autonomic Nervous System of the PNS. You are following the motor pathway from the spinal cord – describe the relative length of neurons and ganglia involved in the transmission of the 2 divisions (Sympathetic and Parasympathetic) of the autonomic nervous system. Make sure to know which division is ‘Fight or Flight’ and which is ‘Rest and Digest’.
