The baby pushes against the cervix, causing it to stretch. normal Uterus 19. The image to the right is an example of: a. a negative feedback loop b. a positive feedback loop Stretching of the cervix causes nerve impulses to be sent to the brain. Oxytocin causes the uterus to contract 20. If the calcium in your blood decreases below the set point, a gland in the brain will sense the decrease and send a chemical message to your bones. Your bones will release calcium into the blood, bringing blood calcium levels back up. This is: a. a negative feedback loop b. a positive feedback loop Umbilical cord Cervix The brain stimulates the pituitary to release axytocin.
