Clinical Effects on the Peripheral Nervous System Due to Excessive Stimulation of Muscarinic Receptors. Excessive Stimulation of muscarinic receptors due to cholinesterase inhibitor poisoning results in increased parasympathetic: (Erdman 2004). 1  Cardiac effects.
A myofibril (also known as a muscle fibril) is a basic rod-like unit of a muscle cell. Muscles are composed of tubular cells called myocytes, known as muscle fibers in striated muscle, and these cells in turn contain many chains of myofibrils.he filaments of myofibrils, myofilaments, consist of two types, thick and thin: 1  Thin filaments consist primarily of the protein actin, coiled with nebulin filaments.
Since smooth muscle is not under our control, it is described as involuntary muscle. The arrangement of contractile proteins in these muscle cells does not give a striated appearance on histological examination; hence the name smooth muscle.
