What does sympathomiminic mean?
An agent that mimics the effects of the sympathetic nervous system.Example: Epinephrine and norepinephrine are sympathomimetic hormones because they produce effects that mimic those brought about by the sympathetic nervous system.
Which of these endocrine glands produce hormones that work with the sympathetic nervous system and cause the fight or flight response?
adrenal glands!
What symptoms might the sympathetic division of the autonomic nervous system produce in a patient experiencing stress?
Blood will most definetly shoot out your anus. For sure.
What does preganglionic sympathetic Stimulation produce?
ACH
What gland is responsible for regulating minerals in the body but is also part of the sympathetic division of the autonomic nervous system?
The adrenal glands (cortex) produce mineralocorticoids. One of these is aldosterone which regulates sodium levels.
What are the general functions of the sympathetic nervous system and the parasympathetic nervous system?
The sympathetic and parasympathetic nervous systems are part of the autonomic nervous system (ANS) which innervates (supplies) smooth muscle, glands, and cardiac muscle.The sympathetic (thoracolumbar) nervous system deals with the fight-or-flight response. It gets the body ready to deal with emergency situations by increasing heart rate, dilating the pupils and airways, decreasing digestive tract motility, and stimulating adrenal glands and sweat glands.The parasympathetic (craniosacral) nervous system restores the body to homeostasis after a stressful or traumatic event/situation. It stimulates the body to decrease heart rate, increase digestive tract motility, constrict pupils, produce tears and saliva, and stimulate thoracic and abdominal viscera.
How do the nervous and circulatory systems interact?
The brain and spinal cord send messages to the heart and blood vessels via the peripheral nervous system, specifically the sympathetic and parasympathetic divisions. The sympathetic nervous system innervates the heart and causes an increases heart rate and force of contraction; it also innervates the blood vessels and can produce either constriction of the blood vessels or relaxation. The parasympathetic nervous system innervates the heart as well, but reduces heart rate and force of contraction. With few exceptions, the parasympathetic nervous system does not innervate the blood vessels. As a consequence of this innervation, the peripheral nervous system regulates heart rate and blood pressure.
What is the function of norepinophine?
Norepinephrine is a catecholamine with multiple roles including as a hormone and a neurotransmitter.Areas of the body that produce or are affected by norepinephrine are described as noradrenergic. One of the most important functions of norepinephrine is its role as the neurotransmitter released from the sympathetic neurons affecting the heart. An increase in norepinephrine from the sympathetic nervous system increases the rate of contractions
What is the difference between epinepherin and norepinepherin?
Epinephrine and norepinephrine are two very structurally similar molecules. They've both involved in the sympathetic part of your autonomic nervous system. Epinephrine (also known as adrenaline) is a hormone which is secreted from the adrenal medulla when activated by the sympathetic nervous system (during times of stress). Norepinephrine (also known as noradrenaline) is a neurotransmitter that is released by neurons in the sympathetic nervous system. Epinephrine and norepinephrine generally produce the same effects as they both interact with adrenergic receptors in the body. Epinephrine is structurally different from norepinephrine as epinephrine has a methyl group (-CH3) attached to the nitrogen atom (making it a secondary amine), whereas norepinephrine is just a primary amine.

Does sympathetic or parasympathetic stimulation produce thicker saliva with more mucus?
Sympathetic. Parasympathetic secretes thin saliva rich in amylase.
Truefalse norephrine releasing fibers are called adrenergic fibers?
yes , true! sympathetic nervous system releases norepinephrine,epinephrine, dopamine neurotransmitters which stimulate adrenegic fibers and produce "fight or flight" so that you can fight that bear!
What is the difference between dopamine and dobutamine?
Dobutamine is a drug that acts on the sympathetic nervous system. Physicians use it to treat heart failure and cardiogenic shock. Dopamine is a neurotransmitter that our bodies produce in order to send signals between brain cells.
