Use diffuse synapses in the Sympathetic arm of the ANS and discrete synapses in the Parasympathetic arm

Use ACh in both arms of the ANS, acting on nicotinic ACh receptors only

Use ACh in both arms of the ANS, acting on nicotinic or muscarinic ACh receptors

Use ACh in the Sympathetic arm of the ANS and NA in the Parsympathetic arm

Use diffuse synapses in both arms of the ANS

The CNS is connected to the target tissue through both sympathetic and parasympathetic divisions

Both the brain and the spinal cord parts of the CNS send efferent input to target tissues

The CNS is connected to the target tissue through two successive sets of neurons

The CNS and target tissue are linked through both afferent and efferent neurons

The CNS is connected to the target tissue through preganglionic or postganglionic nerve fibes

enter the nucleus as a chaperone+receptor+hormone complex

guide steroid hormones to their second messengers

are necessesary for steroid hormones to interact with cytoskeletal proteins

aid steroid hormones to exert genomic effects

are tethered to the plasma membrane

Stimulate the sympathetic system only to increases heart rate and contraction

Stimulate both sympathetic and parasympathetic responses in cardiovascular system

Stimulate the sympathetic system to decrease heart rate and contraction

Stimulate the parasympathetic system to decrease heart rate and contraction

Stimulate the parasympathetic system only to increase peripheral vasodilation and decrease blood flow to heart

Genomic proteins that help G proteins exchange GDP for GTP to become activated

Cytoskeletal proteins that actually hold G proteins in place

Genomic proteins loosely associated with G proteins

Cytoskeletal proteins that are loosely associated with G proteins

Cytoskeletal proteins that facilitate the translocation of steroid hormone receptors to the nucleus

it could be re-uptaken by the nerve terminal

it could bind to an enzyme on the end plate or within the synpatic cleft that degrades acetylcholine

 it binds to acetylcholine receptors on the end plate

competitive binding with an enzyme on acetylcholine receptors

 it could diffuse away from the cleft
