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.
What fibers are the sweat glands innervated by?
Sweat glands are innervated by adrenergic sympathetic nerve fibers from the autonomic nervous system. These fibers release norepinephrine, which stimulates the sweat glands to produce sweat.
Which of these endocrine glands produce hormones that work with the sympathetic nervous system and cause the fight or flight response?
adrenal glands!
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.
If the sympathetic nervous system increases the production of saliva what does the parasympathetic system?
The parasympathetic nervous system primarily decreases the production of saliva. It promotes the rest-and-digest response, which includes stimulating salivary glands to produce a more watery saliva that aids digestion. In contrast, the sympathetic nervous system stimulates a thicker, more viscous saliva, often associated with stress responses. Thus, the two systems work in balance to regulate salivation according to the body's needs.
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
Does sympathetic or parasympathetic stimulation produce thicker saliva with more mucus?
Sympathetic. Parasympathetic secretes thin saliva rich in amylase.
What symptoms might the sympathetic division of the autonomic nervous system produce in a patient experiencing stress?
Activation of the sympathetic division of the autonomic nervous system during stress can lead to symptoms such as increased heart rate, elevated blood pressure, pupil dilation, dilated airways, increased sweating, and decreased digestion. These physiological responses help prepare the body for the "fight or flight" response to perceived threats.
Did Wilkins and Franklin work together to produce the structure of DNA?
No, Wilkins and Franklin did not work together to produce the structure of DNA. They were both involved in the research, but worked separately on different aspects of the project.
What system of the body is the secretion of sweat controlled by?
The secretion of sweat is controlled by the nervous system. Specialized nerve fibers called sympathetic nerves stimulate the sweat glands to produce sweat in response to factors such as temperature, physical activity, and emotions.
