If blood temperature rises too high (stimulus), specialized neurons in the hypothalamus (receptors) of the brain sense the change. These neurons signal other nerve centers(control center), which in turn send signals to the blood vessels of the skin. As these blood vessels (effector) dilate, more blood flows close to the body surface and excess heat radiates (response) from the body. This is an example of negative feedback.2. During childbirth stretching of the uterus triggers the secretion of the hormone oxytocin, which stimulates uterine contractions and speeds up labor, this is an example of positive feedback.3. Positive feedback enhances the original stimulus.4. Negative feedback decreases the original stimulus to maintain a set point What challenge did you face during the learning?
