Homework Answers
Reflexes associated with sympathetic nervous system: Constriction of pupil, sweating is controlled, Heart rate is increased, constrict trachea and bronchi.
Parasympathetic reflexes: Dilatation of pupil, decrease heart rate, normalize the trachea and bronchi.
The parasympathetic nervous system is called as the non-alarm state reflexes in the body and sympathetic nervous system is flight and fight system.
Neurotransmitters in the sympathetic nervous system are :
Preganglionic fibers of sympathetic Nervous system has the neurotransmitter is Acetylcholine and Postganglionic fibres have Norepinephrine at synapses with the effector cells.
Pre and post ganglionic fibers at synapses with the effector cells contains the cholinergic in parasympathetic.

Which of the following is NOT correctly matched regarding the sympathetic system (SYM) and parasympathetic system (PARA)? a. SYM: forms sympathetic trunk b. PARA: has terminal ganglia on or near a visceral organ c. SYM: both pre- and postganglionic neurons have adrenergic receptors d. PARA: both pre- and postganglionic neurons have cholinergic receptors
What is the effect of both the sympathetic and parasympathetic nervous system innervating the same organ/effector?...
What is the effect of both the sympathetic and parasympathetic nervous system innervating the same organ/effector? Both would stimulate the organ. The sympathetic and parasympathetic nervous systems never innervate the same organ/effector. One would inhibit the organ and one would activate the organ. Both would inhibit the organ.
