Term
| What would the injection of phenylephrine or histamine do to blood pressure, sympathetic nerve activity, vagus nerve activity and heart rate, respectively? |

|
Term
| What is the brain stem and what does it regulate? |
|
Definition

Term
| What is the afferent pathway? |
|
Definition
| sensory information about space, activity, temperature and bodily functions |
|
|
Term
| What is the efferent pathway? |
|
Definition
| motor information to respond to changes in the environment and incoming afferent information |
|
|
Term
| What kind of glands are the somatic, autonomic, and enteric/purinerigc nervous systems made up of ? |
|
Definition
| somatic is skeletal. autonomic is smooth and caridiac muscle and glands. enteric is smooth muscles and glands. |
