- Which of the following is correct about the sympathetic division of the autonomic nervous system? Select one: O A. the neurotransmitter released by postganglionic neurons is norepinephrine O B. the neurotransmitter released by postganglionic neurons is acetylcholine O C. sympathetic nerves form synapses in ganglia near or within an internal organ O D. sympathetic nerves exit the central nervous system at the base of the brain and the sacral region of the spinal cord O E. sympathetic nerves typically exit the central nervous system and form ganglia located just outside the brainarrow_forwardWhich of the following is CORRECT regarding the sympathetic ganglia? Group of answer choices It is encapsulated by myeline sheath. It is a network of branching interconneted fibers. It is responsible for regulating the parasympathetic response. It receives nerve fibers arising from the thoracic spinal cord.arrow_forwardWhich of the following statements is true? Chemical messengers within cells are always the main determinant of the effector response. Dual innervation is always present in all organs and glands; one branch enhances the function or secretion, while the other branch inhibits it. The beating of the heart is regulated only by the sympathetic division. Some blood vessels contain alpha adrenergic receptors that cause vasoconstriction in the presence of epinephrine, whereas others have beta adrenergic receptors that cause vasodilation in the presence of epinephrine.arrow_forward
- all of the following apply to the autonomic nervous system except it operates on an involuntary basis it consists of sympathetic and parasympathetic divisions it does not include cranial nerves it is composed of preganglionic and postganglionic neuronsarrow_forwardWhich of the following is correct about the sympathetic division of the autonomic nervous system? Select one: O A. sympathetic nerves exit the central nervous stem at the base of the brain and the sacral region of the spinal cord O B. the neurotransmitter released by postganglionic neurons is acetylcholine O C. the neurotransmitter released by postganglionic neurons is norepinephrine O D. sympathetic nerves form synapses in ganglia near or within an internal organ O E. sympathetic nerves typically exit the central nervous system and form ganglia located just outside the brainarrow_forwardThe sympathetic system plays a vital role maintaining Heart Rate Muscular tone Bowel tone Vascular tonearrow_forward
- Which of the following is stimulated by the Sympathetic nervous system? Question 9 options: Increased dilation of respiratory tubes in lungs during exercise Increased contractions of the digestive system for peristalsis Increased contractions of rectum muscles to defecate Increased saliva and tear production Increased contractions of urinary bladder to urinatearrow_forwardWhich of the following is not correct about the parasympathetic division? Select one: O A. parasympathetic nerves constitute a part of the autonomic nervous system O B. the neurotransmitter released by preganglionic neurons is acetylcholine O C. parasympathetic nerves always form synapses in ganglia near or within an internal organ O D. the neurotransmitter released by postganglionic neurons is acetylcholine O E. parasympathetic nerves exit the central nervous system at the thoracic and lumbar regions of the spinal cordarrow_forwardHow does the baroreceptor reflex raise blood pressure when blood pressure is too low? Stimulates the sympathetics and stimulates the parasympathetics Inhibits the sympathetics and inhibits the parasympathetics Stimulates the sympathetics and inhibits the parasympathetics Inhibits the sympathetics and stimulates the parasympahteticsarrow_forward
- Which of the following is an example of antagonistic control? O The parasympathetic nervous system originates from the brain stem and pelvic nerves, while the sympathetic arises from the thoracic and lumbar spinal cord. O Sympathetic stimulation causes renin secretion by the kidneys, but the kidneys are not innervated by the parasympathetic nervous system. O Parasympathetic stimulation causes bronchoconstriction, while sympathetic stimulation causes bronchodilation. O The vagus nerve innervates much of the viscera, changing the function of each of them independently of the others.arrow_forwardClassify the following characteristics to demonstrate your knowledge of differences between the sympathetic and parasympathetic divisions of the autonomic nervous system. Sympathetic Nervous System Most ganglia lie close to the spinal cord and form two chains of ganglia-one on each side of the spinal cord Increases intestinal motility and stimulates intestinal secretion Postganglionic axons are generally short Preganglionic axons are generally short Postganglionic axons release NE that binds to adrenergic receptors located on the effectors Decreases heart rate, contractility, and conduction velocity Ganglia lie within, or very close to, innervated organs Decreases intestinal motility and inhibits intestinal secretion Long preganglionic axons release ACh that binds to nicotinic receptors located within the ganglia Neurons leave the CNS from the thoracic and lumbar regions of the spinal cord Parasympathetic Nervous System Generalized activation is called the fight-or-flight response…arrow_forwardThe sympathetic and parasympathetic nervous systems are very important in maintaining homeostasis in the human body. In your clinic you meet patients with either high blood pressure or low blood pressure. Explain how you will utilize either the sympathetic or parasympathetic systems to treat either a patient with high blood pressure or low blood pressure? (Take a patient with high blood pressure and describe what you will do and take a patient with low blood pressure and describe what you will do).arrow_forward
