Final answer:
The true statement about Acetylcholine is that it is found in both the peripheral nervous system and central nervous system, where it serves as a vital neurotransmitter involved in muscle activation and other autonomic functions.
Step-by-step explanation:
The correct statement regarding Acetylcholine is: A. Found in PNS and CNS. Acetylcholine (ACh) is a neurotransmitter that is utilized throughout the peripheral nervous system (PNS) and central nervous system (CNS). It plays a crucial role in the activation of muscles and is also involved in various functions of the autonomic nervous system. ACh is essential at the neuromuscular junction (NMJ), where it facilitates communication between motor neurons and muscle fibers. Furthermore, ACh is part of the cholinergic system, which includes both the NMJ and cholinergic synapses distributed in the brain and in the autonomic nervous system.
