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 |
