◉ Fight or flight.... Answer: Epinephrine is released in response to a
threatening event
Epinephrine binds to GPCR's of hepatocytes kicking off a series of
signal transduction events
Cyclic AMP activates protein kinase A, which in turn activates the
enzyme responsible for beginning the breakdown of glycogen
Glycogen is released from cells into the bloodstream to serve a
source of immediate energy.
◉ Insulin is produced/secreted by. Answer: Pancreatic islets
◉ High level of specialization and multiple autonomous nervous
system functions.... Answer: Hypothalamus
◉ Amine. Answer: Lipid soluble - will bind to intracellular receptor
Water soluble - will bind to cell surface receptor
,◉ Neurohormones. Answer: Transported throughout the body and
can effect many different tissues and organs
◉ Neurotransmitters. Answer: Exert local effects within a synapse
◉ Hydrophobic hormone exampl. Answer: Steroids and some
amines... they bind to intracellular receptors on the target cell.
◉ Positive feedback loop. Answer: Labor. It would stop once the
baby is born and nervous signals from the cervix to the brain cease.
◉ What is the target tissue for aldosterone?. Answer: Kidneys
◉ Tropic effects. Answer: Hypothalamus stimulates another gland to
release hormones that go on to elicit an effect on its target tissue
◉ Steroid hormones. Answer: derivatives of cholesterol
◉ Graves' disease. Answer: Muscles are broken down and used to
provide energy for the unusually high metabolic process of other
body systems.
◉ What neurotransmitter is excitatory?. Answer: Epinephrine,
nitrous oxide.
, ◉ What local regulators are responsible for stimulating a greater
response from other cels in te immune system?. Answer: Cytokines,
prostaglandins
◉ Regulation of t3 and t4 is run by what feedback mechanism?.
Answer: Negative feedback.
◉ Hormone that elicits tropic effects. Answer: Thyroid
◉ Hormone that elicits non-tropic effects. Answer: Insulin
◉ Sensory neurons. Answer: Receive information from an organisms
external an internal environment and transmit the information to th
brain
◉ Interneurons. Answer: Connecting neurons that are usually a part
of a circuit. Have the role of integrating information so that a
response can occur.
◉ Motor neurons. Answer: Outgoing messengers , ,specifically these
neurons transmit messages from the brain to muscle fibers or glands
to elicit a desired response.
