The brain
The Autonomic Nervous system is under what category?
What is the Motor pathway or Peripheral Nervous System
what is the sheath called around certain neurons?
myelin sheath
Which gland is considered the master of glands?
Hypothalamus
what is epinephrine?
adrenaline is produced by the adrenal glands, excitatory neurotransmitter as well as hormone. Causes increase in heart rate, blood pressure, breathing rate
What are the three parts of the kidneys?
renal cortex, renal medulla, renal pelvis
What does the medulla oblongata do?
transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration.
what are 2 types of neuron?
sensory and motor neurons
what are the two hormones released from the adrenal gland?
cortisol and aldosterone
What does thyroxine do within the body?
metabolizes fats, proteins and carbs for energy. Stimulates heart, skeletal muscles, liver and kidneys to increase cellular respiration
where does the renal artery lead? where does the renal vein lead?
artery towards the kidneys
vein away from the kidneys
What does the parietal lobe control?
processes sensory information it receives from the outside world, mainly relating to touch, taste, and temperature
What is the state called before an action potential as well as the period an action potential?
resting membrane potential and refractory period
What gland does the pituitary gland mainly effect?
Thyroid Gland and parathyroid
What substance is needed for thyroxine?
Iodine
what are the two section in the beginning of the nephron
glomerulus - capillary network carrying blood
bowmans capsule filters the blood
What is the function of the Pons?
relays information about motor function, sensation, eye movement, hearing, taste
Name a neurotransmitter
acetylcholine, epinephrin, norepinephrine
What six hormones does the anterior pituitary release?
TSH, ACTH, PRL, hGH, FSH and LH
what is hypo and hyperthroidism?
hypo - extremely low levels of thyroxine
Hyper - high levels of thyroxin
where is water permeable? where is water impermeable?
permeable - the descending limb of loop of henle
impermeable - thin portion of the loop of henle
Part of your frontal lobe must be removed, what process, function or sensory could be affect?
it is responsible for cognitive functions such as memory, emotions, impulse control, problem solving, social interaction, and motor function. Therefore these parts could be affected if part is removed
You are a doctor and have seen hat some has just taking Marijuana, what is happening to neurotransmitters and receptors?
THC, the active chemical in marijuana mimics anandamide and binds to cannabinoid receptors. Inhibition is turned off and dopamine is allowed to squirt into the synapse.
what would occur if you have a lack of calcitonin?
You body would not be able to absorb as much calcium within the bones, bone would be brittle and weak. Also calcium is response for part of neurotramission, meaning neuron communication may be faltered
Your body is in a longer term stress response state, what hormone is being released more than it should? what happens after a prolonged period of time in this state?
Cortisol is being released more than it should. You immune system begins to break down
what are the 3 sections of the tubule called? what mainly happens in this sections?
proximal tubule - ions are reabsorbed by the body
loop of Henle - more ions are absorbed back into the body specially sodium
distal tubule - water is reabsorbed into the filtrate, potassium ions are reabsorbed back into the filtrate, active reabsorption of Na+ from the filtrate
