Highlight the areas where your written responses are Highlight the areas where your written responses are similar to the information outlined in the chart.similar to the information outlined in the chart.
Patient Number
Nickname Neurotransmitter Issue
Patient 1 Shaky = 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 7 Pokey = 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
The Endocrine SystemThe Endocrine System
the body’s “slow” chemical communication system
a set of glands that secrete hormones into the bloodstream
Nervous System vs. Endocrine Nervous System vs. Endocrine SystemSystem
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
Hormones are SpecificHormones are SpecificOnly 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
Pituitary GlandPituitary 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
anterior pituitary lobe
releases hormones that
regulate organs and other glands.
posterior lobe regulates water and salt balance.
Thyroid & Parathyroid Thyroid & Parathyroid GlandsGlands Regulate metabolism and calcium
Problems =◦ Hyperthyroidism – nervousness,
tremors, hunger, weight loss, protruding eyes
◦ Hypothyroidism – fatigue, weight gain, mental impairment
Adrenal GlandsAdrenal 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
PancreasPancreasRegulates sugar metabolism by
producing insulinProblems = diabetes, cancer,
pancreatitis
Pineal GlandPineal GlandConnects endocrine syst
with nervous systReleases melatoninProblems = disruptive sleep
GonadsGonadstesticles or ovariesProduce sex hormones: estrogen,
progesterone, testosteroneProblems = cancer, fertility issues
