Describe the structure of the body, from simplest to most complex, in terms of the six levels of organization. Unique features of smooth muscle cells are that it stretches wihtout developing tension which is important for the bladder and the stomach. A myofiber is made up of many myofibrils. Internal movement: Smooth and skeletal muscle tissue is responsible for "hidden movement", including breathing, digestion, circulation of blood, urination and defecation. Will you be able to figure out the molecular mechanisms that underlie muscle contraction? Identify the four requirements for human survival. Intercalated discs join adjacent cardiac myocytes (*double check*) and adhering junctions occur on transverse sfc; attachment points for actin filaments of last sarcomere of myofibrils, desmosomes are on transverse sfc, and gap junctions are on the longitudinal surface.

I am thankful to the authority of This app for making this application. Muscular thermoregulation-In rest, contractions of skeletal muscles produce up to 30% of the body heart. 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. When these arteries relax, more blood flow to the skin which increases heat loss.

Cell contraction is an all or nothing phenomenon. Smooth muscle is found in the wall of the arteries that supply blood to the skin. Muscle fatigue is due to low ATP and increased lactic acid. 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.
