AHL is relatively rare (less than 100 cases have been reported in the medical literature as of 2006), it is seen in about 2% of ADEM cases, and is characterized by necrotizing vasculitis of venules and hemorrhage, and edema.
Acetylcholine has functions both in the peripheral nervous system (PNS) and in the central nervous system (CNS) as a neuromodulator. In the peripheral nervous system, acetylcholine activates muscles, and is a major neurotransmitter in the autonomic nervous system.
Structure of acetylcholine (ACh). 11.2 Acetylcholine in the Autonomic Nervous System. In the autonomic nervous system, acetylcholine (ACh) is the neurotransmitter in the preganglionic sympathetic and parasympathetic neurons. These are shown in Figure 11.2 as the red ACh in the ganglion.t is now known to be a neurotransmitter at all autonomic ganglia, at many autonomically innervated organs, at the neuromuscular junction, and at many synapses in the CNS. In this chapter we will discuss the acetylcholineâs anatomy, cell biology, physiological effects, role in behavior, and clinical applications.
