Homeostatic Negative Feedback does what?

Reserve a change

  • regulation of blood pressure

3
New cards

Homeostatic Control Mechanisms (negative feedback - blood pressure) Receptor

Receptor—when and individual stands up blood pressure drops—baroreceptors in the carotid sinus and arch of aorta detect this

4
New cards

Homeostatic Control Mechanisms (negative feedback - blood pressure) Afferent Pathway + Control Center

Afferent Pathway—glossopharyngeal and vagus nerves carry signal to control center

Control Center—medulla oblongata of the brain stem integrates the information and plans an appropriate response

5
New cards

Homeostatic Control Mechanisms (negative feedback - blood pressure) Efferent Pathway + Effectors

Efferent Pathway—sympathetic nerve fibers carries signals to the effectors—heart and blood vessels

Effectors—heart will beat faster and stronger in response to sympathetic innervation—blood vessels will vasoconstrict—blood pressure will increase
