| Answer |

|
| What is the function of the CVC and where is it located? |
exerts Autonomic control over the Heart/Aterioles - Medulla |
| How does the CVC exert Aunomic control? |
Inhibitory, Excitatory input from Peripheral Receptors |
| What is the function of Pressreceptors/Baroreceptors? |
INHIBIT the CVC - sensitive to HIGH BP --> DECREASE BF |
| Where are Pressreceptors/Baroreceptors located? |
Aortic Arch, Carotid bodies |
| name 2 Excitatory Peripheral Receptors. |
Chemoreceptors, Mechanoreceptors |
| What is the function of Chemoreceptors? |
EXCITE the CVC - sensitive to LOW O2 in the blood --> INCREASE BP |
| What is the function of Mechanoreceptors? |
EXCITE the CVC - sensitive to Movement --> INCREASE BP |
| Where are Mechanoreceptors located? |
Joints, Skeletal Muscles |
| What would be the Inhibitory input response to decreased Sympathetic? |
Vasodilation (alpha-adrenergeric) --> decrease PR --> decrease MAP = decrease BF
|
| What would be the Inhibitory input response to increased Parasympathetic? |
decrease HR --> decrease MAP = decrease BF |
| What would be the Excitatory input response to increased Sympathetic? |
Vasoconstriction (alpha-adrenergic) some Vasodilation (ß2-adrenergic) --> increase PR --> increase MAP = increase BF |
| What would be the Excitatory input response to decreased Parasympathetic? |
increase HR --> increase MAP = increase BF |
