1. PRACTICE FRQ: Use the chart in order to evaluate your FRQ. Highlight the areas where your written responses are similar to the information outlined in the chart. Patient Number NicknameNeurotransmitter Issue Patient 1Shaky = might be suffering from Parkinson’s Disease Dopamine = related to regulating movement, reward, focus, hallucinations, and delusions Patient 2 Zippy = probably has excess energy and is overly stressed and anxious. May be seeking treatment for those ailments Norepinephrine = related to energy, anxiety, and panic attacks, causes heart rate to increase Patient 3 Boozer = might pass out, looks drunk b/c has high amounts of GABA GABA = major inhibitory neurotransmitter, “nature’s valium” Patient 4 Coolie = has high levels so he probably has very little anxiety & is willing to take risks or be involved in illegal activities Serotonin = high levels are related to relaxation and emotional wellness, but can also lead to impulse control problems. If too high can lead to Serotonin Syndrome Patient 5 The Professor = probably seeking treatment because too much glutamate can over-excite neurons and destroy them Glutamate = major excitatory neurotransmitter related to learning and memory Patient 6 Poppy = has high dopamine levels so is probably numb to pain and feels pretty good, but could lose consciousness and possibly die if levels get too high Endorphins = act like opiates, linked to pain control and pleasure center, reduces pain by inhibiting it Patient 7Pokey = has a lack of energy and all he wants to do is hang out and rest, can’t properly react to stressful situations Acetylcholine = related to parasympathetic nerv system, plays a role in memory, movement, arousal & attention

2. The Endocrine System  the body’s “slow” chemical communication system  a set of glands that secrete hormones into the bloodstream

3. Nervous System vs. Endocrine System Nervous System Chemicals = neurotransmitters Nervous system secretes neurotransmitters into CNS Signals sent in fractions of a second Endocrine System Chemicals = hormones Endocrine system secretes hormones into blood stream Chemicals can take many seconds to begin working, effects can last longer (hours, days) Both: Regulate conditions in body Use chemicals for communication

4. Hormones are Specific Only certain cells in the body can respond to hormones and, often, only at limited times. ◦ In order for cells to respond they must have the hormone receptor molecule Example: Oxytocin= released by the pituitary gland ◦ Acts on only 2 tissues, the breasts and uterus ◦ Only under certain conditions  causes uterine contractions  causes breast tissue to produce milk

5. Pituitary Gland Controlled by the hypothalamus Called the “master gland” anterior pituitary lobe releases hormones that regulate other glands posterior lobe regulates water & salt balance Problems = growth disorders, fertility probs, impotence

6. anterior pituitary lobe releases hormones that regulate organs and other glands. posterior lobe regulates water and salt balance.

7. Thyroid & Parathyroid Glands Regulate metabolism and calcium Problems = ◦ Hyperthyroidism – nervousness, tremors, hunger, weight loss, protruding eyes ◦ Hypothyroidism – fatigue, weight gain, mental impairment

8. Adrenal Glands Important in stressful/emotional situations ◦ adrenal cortex  Secretes cortisone, which speeds up metabolism ◦ adrenal medulla  secretes epinephrine and norepinephrine hormones Problems = ◦ Addison’s Disease - skin, weight & dizziness ◦ Cushing’s Disease - muscle & bone disease

9. Pancreas Regulates sugar metabolism by producing insulin Problems = diabetes, cancer, pancreatitis

10. Pineal Gland Connects endocrine syst with nervous syst Releases melatonin Problems = disruptive sleep

11. Gonads testicles or ovaries Produce sex hormones: estrogen, progesterone, testosterone Problems = cancer, fertility issues
