In the peripheral nervous system, Ach serves to what cardiac muscle and what skeletal muscle?
hi..this is for my Biology homework and it's starting to get on my last nerves.

The main neurotransmitters of the peripheral nervous system are acetylcholine and noradrenaline. However, there are several other neurotransmitters as well, jointly labeled Non-noradrenergic, non-cholinergic (NANC) transmitters. Examples of such transmitters include non-peptides: ATP, GABA, dopamine, NO, and peptides: neuropeptide Y, VIP, GnRH, Substance P and CGRP.
The chemical compound acetylcholine (often abbreviated ACh) is a neurotransmitter in both the peripheral nervous system (PNS) and central nervous system (CNS) in many organisms including humans. Acetylcholine is one of many neurotransmitters in the autonomic nervous system (ANS) and the only neurotransmitter used in the motor division of the somatic nervous system. (Sensory neurons use glutamate and various peptides at their synapses.) Acetylcholine is also the principal neurotransmitter in all autonomic ganglia.
There are two main classes of acetylcholine receptor (AChR), nicotinic acetylcholine receptors (nAChR) and muscarinic acetylcholine receptors (mAChR). They are named for the ligands used to activate the receptors.Source(s): wikipedia

Think about it. What does cardiac muscle possess that skeletal muscle doesn't? Cardiac muscle is made up of cells that act similarly to neurons. There's a steady flow of action potential that never dissipates and least to a steady, unceasable beat. Keep in mind that pacemaker cells are responsible for this event.
