Labster 1 cell structure - CELL STRUCTURE BIOCHEMISTRY CELL - StuDocu Holds thick filaments in place; helps recoil after stretch; resists excessive stretching, extends from Z discs to thick filament and runs within the thick filament to attach to M line; holds thick filaments in place, Links thin filaments to proteins of sarcolemma, an elaborate smooth endoplasmic reticulum; regulates intracellular levels of ionic calcium; stores calcium and releases it on demand when contracting, dilated end sacs of the sarcoplasmic reticulum, formed by t tubules that run between the paired teminal cisternae of SR; organelles come into closest contact here; encircle each sarcomere, states that during contraction the thin filaments slide past the thick ones so that the actin and myosin filaments overlap to a greater degree, a neural impulse; a brief electrical charge that travels down an axon; a large change in membrane potential that spreads rapidly over long distances within a cell, the neurotransmitter that motor neurons use to tell skeletal muscle to contract, opened by neurotransmitters; creates small local changes in the membrane potential, Channels that open or close in response to a change in the membrane potential; underlie all action potentials, point of contact between a motor neuron and a skeletal muscle cell; motor end plate, a gap into which neurotransmitters are released from the axon terminal, small membranous sacs containing neurotransmitter ACh, Sequence of events by which transmission of an action potential along the sarcolemma leads to the sliding of myofilaments. It is formed by groups of smooth muscle cells interconnected by gap junctions which allow the transmission of action potentials between cells meaning motor neurons can stimulate more than one cell simultaneously.
