Response of a homeostatic system occurs through a feedback loop
- Stimulus
- Detection of stimulus by receptor
- Information relayed to the control center
- Integration of the input by the control center and initiation of change through effectors.
- Return of Homeostasis by the actions of effectors
Temperature Regulation:
- Body temperature drops
- Sensory receptors detect this and signal the hypothalmus (Component of the brain)
- Hypothalamus alert nerve impulses in blood vessels in the skin to “decrease” the inside opening of the vessles.
- This decrease amount of blood circulating to the surface of the body.
- Less heat is released through skin
- Nerve impulses are sent to SKELETAL muscles, causing Shivering
- Nerve impulses are sent to smooth muscles of hair follicles , causing “ Goose Bumps”
Body Temperature RISES
- Sensory receptors detect this and signal the hypothalamus
- Hypothalamus alert nerve impulses in blood vessels in the skin to “increase” the inside opening of the vessels
- This increases the amount of blood circulating to the body surface
- More heat is released through the skin
