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.
smooth muscle. a type of muscle that is nonstriated (no a or I band) has no t tubules, reduced rs, dense bodies instead of z lines; thin, thick and intermediate filaments.it requires energy, calcium, nerve supply, but not for every cell.it also has gap junctions. type of muscle that is nonstriated (no a or I band) has no t tubules, reduced rs, dense bodies instead of z lines; thin, thick and intermediate filaments.
