Feed, cry, gag, pee, poop, breathe - breatheSuck, scare, babble, cry, sleep, coo - babbleSuck, swallow, startle, rooting, grasp, babinski - babinski 8 Where do sequence behaviors come from? What are some examples? The forebrain - sleeping, breathing, blinkingThe hypothalamus - anger, fear, happinessThe central pattern generator - walking, stretching, yawning 9 Name 3 places movement comes from and what those areas do : Primary motor cortex (in precentral gyrus) - all movement, Lateral Corticospinal tract (pyramidal tract) - limbs, Medial Corticospinal tract - middle of bodyForebrain - face muscles, midbrain - middle of body, medulla - involuntary movementPrimary motor cortex (hypothalamus) - limbs, Medial tract - everything, Lateral tract - middle of body 10 What does the Cerebellum control? What happens if it is damaged? Controls laughter - laugh a lotControls a lot of movements - looks like you are drunkControls a lot of thinking - resembles Down syndrome 11 Which pathway starts to degenerate in Parkinsons? Hint - in Basal Ganglia Pathway from hypothalamus to thalamusPathway from cerebellum to caudate nucleusPathway from substantia nigra to caudate nucleus 12 3 types of paralyses and where the injury that caused them is sustained? Paralysis - damaged motor neurons in spinal cord, Flaccid paralysis - damaged lower motor neurons, spastic - damaged axons from brain to spinal cordTemporary - damaged thalamus, permanent- damaged cerebellum, random - damaged nuerons in the medullaLimp - damaged motor neurons in limbs, riggid - damaged nerves, frantic - damaged axons in hypothalamus 13 Paraplegia is to lower part of body as Quadriplegia is to _______ and Hemiplegia is to __________. Hands and feet, top side of bodyAll four limbs, one side of the bodyFingers and toes, an arm and a leg 14 What spinal cord disorder is a late stage of syphilis? What happens? Totificus Totalis - loss of genital feelingPolymorphisis - loss of feeling from legs downTabes Dorsalis - Loss of function in the legs, bladder and bowel 15 What is Poliomyelitis? Paralysis of muscles controlled by motor nerves from affected areas in the spinal cord - because of damaged cell bodies of motor nueronsParalysis of muscles controlled my damaged axons in the spinal cordA beach paradise 16 Amyotrophic Lateral Sclerosis, more commonly known as Lou Gehrig's disease, is caused by what? What occurs during this disease? Lou Gehrig was cool... .Degeneration of axons in the arms and legs - slowly become paralized from the legs upDegeneration of motor neurons in the spinal cord, medulla and cortex - slow paralysis - first arms then legs 17 What is the cause of Parkinson's disease? The treatment? Degeneration of the path from the substantia nigra to the caudate nucleus and putamen (transmit dopamine) - L-Dopa, pill that becomes dopamineDegeneration of the path from the basal ganglia to the caudate nucleus - serotonin injectionsDegeneration of the tissue around the basal ganglia - stretching and yoga 18 Huntington's disease is much like Parkinson's although it is slightly different. What are the main differences? It is genetic - abnormality on chromosome 8, stats way later and death is less likelyIt is genetic - abnormality on chromosome 4, begins earlier and die younger - 5 years after onset, no treatment availableIt is caused by infection in the brain from various chemicals, death is immediate, no treatment 19 What is Myasthenia gravis? symptoms? treatment? An autoimmune disease that attacks ACh receptors - weakness, rapid fatigue, mostly in elderly - suppress the immune system or inhibit acetylcholinesteraseAn autoimmune disease that attacks serotonin receptors in the brain - depression, anxiety, in young people - suppress immune systemA rash - itchy, burning - no treatment 20 Where do the tremors with Parkinson's start? What is the chemical that is the problem? is it genetic? In the hands - APM+ - noIn the face - MPP+ - only when onset before 50In the legs - PMP+ - only after the age of 65 21 Circannual rhythm is to _______ as circadian is to ___________. A year, 24 hoursA week, 12 hoursEating and drinking, migration 22 Which are 3 elements that keep us in our circadian rhythm? Food, water, toiletSun, moon, starsLight, temperature, noise 23 Where is your biological clock located? What happens if you damage it? In your thalamus - you are freeTip of the hypothalamus, suprachiasmatic nucleus - live by no patternsTip of the optic nerve - see in black and white 24 What is the Retinohypothalamic? What does it do? A strip of ganglion cells - connects the eye to the SCNA strip of lateral cells - connects the mouth to the FECA rhyno with big eyes. 25 Where does Melatonin come from? What does it do? The sleep fairy - makes you fall asleepThe retinol gland above the thalamus - SCN turns it on when it is time to wake upThe pineal gland behind the thalamus - SCN turns gland on to make you tired 2-3 hours before bed 26 What kind of waves are happening when you are at stage 0, stage 1-2, stage 3-4? Alpha waves, Theta waves, Delta wavesZeta waves, Tau waves, Omega wavesTheta waves, Delta waves, Alpha waves 27 When does the sleep spindle and K complex take place? During Stage 1During Stage 2During Stage 3 28 What happens during REM sleep? We dream, our bodies are deeply relaxed and won't move.We are still falling asleep.We are dreaming but it doesn't make sense. 29 What is REM rebound? Why do we sleep? When we skip over REM - to recoverWhere we go through REM several times - to relaxIf our brain is deprived of REM sleep, it will catch up - speeds up other stages. - to dream 30 What happens if you make a cut across the midbrain? If you cut off brain from ascending reticular system? Prolonged coma - ascending neurons can't wake brain upParaplegia - no communication to brainHyperplegia - the thoughts are trapped and can't get out A mistake in this Quiz ?
