Compare and contrast the sympathetic nervous system and the parasympathetic nervous system in terms of neurotransmitters secreted by pre and post ganglionic neurons as well as receptors found on post ganglionic neurons and effector cells.

Homework Answers

Answer #1
Sympathetic parasympathetic
Outflow thoraco lumbar outflow cranio sacral outflow
Pre Ganglionic neurotransmitter Acetylcholine Acetylcholine
Post Ganglionic neurotransmitter Nor-epinephrine Acetylcholine

Receptors on post G

neuron

Nicotinic receptors (N​​​​​​G)

Nicotinic receptors (N​​​​​​G)
Receptors on effectors alpha and Beta adrenergic receptors Muscarinic receptors

Exception to above -

Sympathetic supply to sweat gland - Muscarinic receptors on effectors.

Which of the following is a difference between the sympathetic and parasympathetic nervous systems? - Norepinephrine is released exclusively from post ganglionic fibers in the sympathetic system. - The adrenal gland enhances responses from the parasympathetic system. - The sympathetic system nerves exit the spinal cord in the cervical region of the vertebral column. - Postganglionic fibers are longer in the parasympathetic system. - All of these are differences in the autonomic nervous system.
