Thymus –f. Adrenalg. Pancreash. Ovariesi Testes7. What works like a heating system turning on and off?8. Define negative feedback -Master gland that controls other glands and growthControls the release of energy from foodmolecules inside cells.Regulate the amount of calcium in the blood.Helps develop the immune system during childhoodTriggers the body’s response to emergencies. Affect salt & Water balance in kidneys and sugar in bloodProduces insulin and glucagon that control glucose in blood.Release female sex hormones such as estrogenMale sex hormone, produces testosteroneNegative FeedbackWhen the amount of a particular hormone in the blood reaches a certain level, the endocrine system sends signals that stop the release of that hormone.

Give an example of a stimulus and a response12. What are nerve cells called?13. This neuron picks up stimuli from the internal and external environment and turns it intonerve impulses. ____________________________________.14. This neuron is usually in the brain and spinal cord and carries impulses from one neuron to the next. _______________________The NS receives info about what is happening both inside and outside your body. It also directs the way in which your body responds to this info. In addition, your NS helps maintain homeostasis.A stimulus is a change in the environment that can make an organism react. A response is what your body does in reaction to a stimulusA buzzing fly is a stimulus, a swat to the fly is a response.NeuronsSensoryinterneuron15.
