- a A molecule that is released from the synaptic terminal of a neuron at a chemical synapse, diffuses across the synaptic cleft, and binds to the post synaptic cel, triggering a response
- b The short time immediately after an action potential in which the neuron cannot respond to another stimulus, owing to the inactivation of voltage-gated sodium channels
- c An extension of the hypothalamus composed of nervous tissue that secretes oxytocin and antidiuretic hormone made in the hypothalamus, temporary storage site for these hormones.
- d The internal systems of communication involving hormones, the ductless glands that secrete hormones directly into the interstitial fluid, from which they diffuse into the bloodstream.
- e The ventral part of the vertebrate forebrain; functions in maintaining homeostasis, especially in coordinating the endocrine and nervous systems; secretes hormones of the posterior pituitary and releasing factors that regulate the anterior pituitary

5 True/False questions
Sympathetic Division → One of the tree divisions of the autonomic nervous system; generally increases energy expenditure and prepares the body for action (Fight or Flight) - causes increase in heart rate, breathing, slows digestion, liver releases glucose, inhibits emptying of bladder, releases adrenaline from adrenal medulla situations:(emergency, embarrassment, exercise, excitement)
Troponin → The regulatory protein that control the position of tropomyosin on the thin filament.
Organs → A specialized center of body function composed of several different types of tissues
Muscle Tissue → Tissue made up of neurons and supportive cells.
Parasympathetic Division → One of the three divisions of the autonomic nervous system; consists of networks of neurons in the digestive tract, pancreas, and gall bladder; normally regulated by the sympathetic and parasympathetic divisions of the autonomic nervous system. (secretions + peristalsis can function independently from parasympathetic and sympathetic but can also be affected by it)
