Deck 21: The Nervous System

Question 1

Answer 1

1. c; 2. e; 3. a; 4. d; 5. f; 6. b

Question 2

Match the following divisions of the nervous system with the proper description.

Answer 2

When a sensory neuron is stimulated, the impulse travels to the spinal cord, and in most cases to the brain as well. Reflexes may result in movement of voluntary, involuntary, or cardiac muscles. The sympathetic system typically involves speeding up processes; the parasympathetic returns the body to homeostasis. The free nerve ending that begins this process is located in the skin or organ in question; the cyton is in the dorsal root ganglion. The dendrite then makes a synapse in the spinal cord or brain, and ultimately the motor neuron exits via the ventral root. The cyton for this neuron is located in the brain or spinal cord, so the cellular extension that goes out to the effector is the motor axon.
