Ms. C’s Rapid Fire Review!! Instructions: 1.As you listen to the review, jot down anything that confuses you or helps you remember a term or concept. 2.Make a mark by terms you know you need to study or memorize better!

III. Endocrine System What? Network of glands located in brain and body Function? Sends hormone chemical messages through blood stream to body’s organs to control: – metabolism – growth – sexual development – flight or fight response In females: ovulation, menstruation, and lactation In males: sperm production, deepening of voice, growth of sex organs What?

III. Endocrine System (cont) Thyroid gland produces hormone that regulates metabolism (how quickly/slowly one digests food) – Not enough hormone (hypothyroidism)= sluggish, no appetite – Too much hormone (hyperthyroidism)=eat a lot, hyperactive Adrenal glands release cortisol & epinephrine (adrenalin) when person frightened or angry Hypothalamus (part of limbic system) coordinates communication between endocrine and nervous systems Pineal gland “3 rd eye” releases melatonin which regulates sleep cycle (circadian rhythms) Pituitary gland—”master gland” Maker of growth hormone, second in command to hypothalamus directs other glands to produce/release hormones Parathryroid—produce calcium for bone growth Thyroid gland produces hormone that regulates metabolism (how quickly/slowly one digests food) – Not enough hormone (hypothyroidism)= sluggish, no appetite – Too much hormone (hyperthyroidism)=eat a lot, hyperactive Adrenal glands release cortisol & epinephrine (adrenalin) when person frightened or angry Hypothalamus (part of limbic system) coordinates communication between endocrine and nervous systems Pineal gland “3 rd eye” releases melatonin which regulates sleep cycle (circadian rhythms) Pituitary gland—”master gland” Maker of growth hormone, second in command to hypothalamus directs other glands to produce/release hormones Parathryroid—produce calcium for bone growth pancreas secretes insulin for maintaining proper blood sugar levels

a)yo gaba gaba slows you down! b)glutamate excites! c)serotonin calms d)dopamine Dopey, happy, makes you want to keep doing whatever you’re doing e)ACh achoo!! muscle contractions f)enrophins end your pain! attach to opiate receptors g)oxytocin the bonding and trust chemical

not enuf ACh becuz neurons killed! not enuf serotonin left frontal lobe can’t talk fluidly left temporal lobe word salad temporal lobe damage not enuf dopamine too much dopamine not enuf oxytocin head injury parietal lobe damage 1.brian waves 2.functional imaging 3.structural imaging 4.radioactive glucose functional image 5.xray structures

secretes insulin to maintain blood-sugar levels

Label the following AND identify their functions: axon axon terminals cell body (AKA soma) dendrites myelin sheath Node of Ranvier Schwann’s cells

Label the following: axon dendrite neurotransmitters presynaptic membrane postsynaptic membrane receptor terminal button synapse (AKA cleft/gap) synaptic vesicles Describe the process that is shown in the diagram:

What is happening in the neuron at points 1, 2, 3, & 4 of the line graph? 1.neuron has been stimulated to the threshold by enough neurotransmitters opening the ion channels on the dendritic receptors to let enough Na+ in –It will now fire because of all-or-nothing principle 2.Neuron has had an action potential and fired because between points 1 & 2 it is becoming depolarized as sodium enters and potassium leaves 3.Neruon is hyperpolarized and thus in a refractory period during which it cannot fire 4.Neuron is returning to polarized state and resting potential What is happening between points 1 & 2? depolarization Between points 2 & 3? repolarization (sodium getting kicked out, potassium coming back in) From 3 to 4? neuron is returning to polarized state and resting potential Describe what is happening at & between different points on the graph to the left.

1.What is the function of the reuptake transporter? To deliver neurotransmitters back to neuron that released them so they can be repackaged 2.What happens if the reuptake transporter is blocked by an agonist like cocaine? The neurotransmitter remains in the synapse until it is broken down by glial cells or the cocaine is broken down; it will keep locking on to the receptors of post-synaptic neurons causing additional action potentials 3. How do you know if something is the presynaptic vs. postsynaptic membrane? (e.g. what is the difference between the 2 or where do you find them?) Presynaptic is on the axon terminal side; post-synaptic is the membrane of the dendrites of receiving neuron

Label the following: Forebrain Cerebral cortex Limbic system Hindbrain Midbrain

1. Label the following AND identify their main function(s): frontal lobe prefrontal lobe parietal lobe occipital lobe cerebellum medulla pons temporal lobe 2. What is a sylvian fissure and between which lobes is it located? It is the sulcus between the temporal and frontal lobes (AKA fissure of Rolando)

Label the following AND identify their functions: motor cortex somatosensory cortex Broca’s area auditory cortex visual cortex Wernicke’s area

Identify all of the # areas depicted in this cross section of a brain cerebrum/cerebral cortex corpus callosum ventricle ventricles are fluid filled cavities in brain that cushion the brain during head trauma, help remove waste, and transport hormones to different parts of brain The fornix connects hypothalamus to hippocampus for communication between the 2 fornix thalamus pituitary gland pons medulla spinal cord cerebellum midbrain/RAS

1. What are the functions of the cigulate gyrus, pineal gland, and fornix? cingulate gyrus: coordinates sensory input with emotions involved in emotional response to pain regulates aggressive behavior pineal gland: releases melatonin that helps regulate circadian rhythms (sleep/awake cycle) fornix: connects hypothalamus to hippocampus

Endocrine System Label the diagram with the names and functions of each part! Use the following terms: pineal gland hypothalamus pancreas thyroid parathyroid testes ovaries pituitary gland Note: Thymus plays role in immune system
