acetylcholine is
A
excitatory in cardiac muscle
B
excitiatory in skeletal muscle
C
inhibitory in all synapses in the body
D
powerful in the brain
Explanation: 

Detailed explanation-1: -However, through the nicotinic cholinergic receptors, acetylcholine allows for skeletal muscle contraction; in the adrenal glands, the release of adrenaline and norepinephrine; and in the peripheral sympathetic ganglia, activation of the sympathetic system with the release of norepinephrine.

Detailed explanation-2: -Acetylcholine, the major excitatory neurotransmitter to the smooth muscle of mammalian intestine1, is known to depolarize smooth muscle cells with an apparent increase in membrane conductance2.

Detailed explanation-3: -Muscle contraction is controlled by receptors in the muscle cell membranes that respond to the neurotransmitter acetylcholine when it is released from motor neurons.
