An excititory neurotransmitter - released during arousal but inhibited with melatonin - helps people fall asleepA hormone - released when aroused - makes you stop itchingA shot you can get - helps make you stronger - makes you weaker if needed 2 What is GABA responsible for in sleep? and the Pons? When we cross over into stage one of sleep - triggers onset of REMKeeps us awake longer - kicks us out of REMMakes us tired - makes us less tired 3 What does PGO stand for? what do PGO waves do? Potential, Generitic, Onset - wake us upPowerful, Ginger, Only - discriminate against blondes and brunettesPons, Geniculate, Occipital Cortex - starts REM, makes us dream in color 4 How does the REM cycle work? The Pons sends the cerebellum a message to stop moving, then after neurons secrete dopamine to excite usThe Pons sends a message down the spinal cord to release ACH makes us relax, then after secrete serotonin to shut off REMWhat kind of a question is this? 5 What can lead to Insomnia? What is it common among? Stress, anxiety, brain tumors, depression - mental disorderEnergy drinks, caffiene, vitamin B - coffee addictsOld age - elderly people 6 What causes SIDS? Baby rolled onto stomach and couldn't breatheMostly in Premi babies - lungs don't get excercise in womb, not fully developed, stop breathing in sleep - medulla is immatureLungs are too weak to function properly 7 Most common victims of sleep apnea? All genders, all ages - anyone could fall victimWomen, young people - medulla doesn't function properlyMales, elderly, obese people - medulla slows down or weight on trachea and lungs 8 What is Narcolepsy? Autoimmune disease - lapse into sudden sleep - lack orexin, cells that keep us awakeSTD - can no longer be aroused - messes with hypothalamusInfection - makes us tired - just need extra vitamin B 9 Periodic Limb - Who?

FreudAdlerHall 14 Name 2 Biology concepts behind sleeping. Reticular Activation - eyes are less stimulated - Anatomicalious - the brain slows down dramatically to sleepActivation Synthesis - spontaneous activity to figure out what is going on - Clinical Anatomical - sleeping is unconscious dazing offSynchronization - the mind and body in sync - Reevaluation - dreaming 15 Our temperature is homeostatic, is this good? Where is this regulated? Is Fever good? Yes, gives us an advantage. Preoptic/Anterior - shivering and sweating. Yes if low-kills bacteria -if too high -fatal.No, it makes us vulnerable to weather and environment. the hypothalamus. No, it is dangerous.Yes, it keeps us at exactly 98. 6. The thalamus regulates it. Yes, it kills bacteria and poses no threat to us 16 What is the route fever takes? The yellow brick roadStarts with leukocytes, then cytokines (attack), stimulates Vagus Nerve which tells hypothalams to release ProstaglandinsWhite blood cells, then red blood cells, stimulates optic nerve, then signals thalamus that bacteria is gone 17 Two types of thirst? differences? Posterior Pituitary - when we NEED water-will conserve it- releases hormone Vasopressin (ADH). Osmotic thirst - when we eat salty foods-receptors around 3rd ventricle detect thirst.Neccessary thirst - actually need water - Plain thirst - casually thirstyNeed for water - need for the D. HAHAHAHAHAAH 18 What causes Hypovolemic Thirst? what will help? Not actually thirsty, just think you are.Loss of too much weight - body conserves all fluids because not taking them in.Loss of severe amount of body fluids - bleeding, diarrhea, vomiting - need saline - kidneys release renin to conserve water 19 What is the enzyme that decreases after birth? Nerve stimulated when hungry? Organ that slows food coming in so that the body can absorb the food? Lactase - Vagus - DudeumLactase - Pineal - RodigemLimbis - Cranial - Esophagus 20 Leptin is produced by___? What does it do? Humans are______ to it after a while. Fat cells - tells us what weight we are supposed to be at - insensitiveMuscle tissue - tells us to eat more - suseptibleProtein - makes our muscles grow - addicted 21 Lateral Hypothalamus is to _________ as Ventromedia is to _______ when it comes to eating.

What are their two main purposes? The pineal gland - to arouse and to stimulateThe adrenal gland - organizing effects and activating effectsThe reticular gland - sequence effects and consistent effects 24 Wolffian ducts are to _________ as Mulleran ducts are to __________. The SRY is... ? Female, male. A female estrogen secretion center on the X - inhibits the Wolffian ductsMale, female. A sex determining region on the Y - secretes testosterone and inhibits the Mulleran ductsBlue, black. Three confusing letters. 25 If NOTHING happens by 12 weeks after conception... ? What is the MPOA and what makes it grow? Fetus develops as a female. Medial Preotic Nucleus - testosteroneFetus doesn't make it. Mild Pineal Organizing Area - histamineFetus is a boy. Mid Period Optional Arrival - dopamine 26 What happens during Aromatization? What is alpha fetal protein? Sense of smell develops - helps build the cartilidge in the nose.Testosterone enters the neuron and becomes estrogen - masculinizes the brain. Protein that binds with estrogen in the blood.Serotonin enters the neuron and shuts down all hormone growth. protein that helps fetus beat serotonin. 27 MPOA nuerons release _______ during _______ and _______. ________ is needed to prime MPOA. Serotonin, eating, sleeping. DopaminePregesterone, pregnancy, period. estrogen.Dopamine, foreplay, orgasm. Testosterone 28 Mestrual cycle is ____ days. Pituitary gland releases____ when estrogen is too high and _____ when estrogen reaches threshold. When this happens the egg bursts out of the folicle and releases _______. No pregnancy, ______shuts off all hormones. 28, FSH, Lutinizing hormone, progesterone. Hypothalamus30, SFH, LH, estrogen. Thalamus26, LH, FSH, dopamine. Reticular activating system. 29 What does the birth control pill do to control pregnancy? It depletes both estrogen and progesterone - the mini depletes 1.Keeps estrogen and progesterone very high - body thinks its pregnant - the mini : only 1 is very high.It won't let you have sex. 30 Mix of male and female - _____?
