ATP generates through THIS and THIS
what is glycolysis and aerobic metabolism
the four properties of muscular tissue are electrical excitability, contractility, extensibility, and THIS
the two contractile proteins, also known as thick and thin filament, are THIS and THIS
what are actin and myosin
two regulatory proteins that block the binding site of myosin, preventing myosin from binding to actin, are THIS and THIS
what is troponin and tropomyosin
THIS is half the diameter of fast fibers and take 3x as long to reach peak tension after stimulation; higher oxygen supply, contain myoglobin. (red muscles)
THIS and ATP can power maximal muscle contraction for about 15 seconds and is used for maximal short bursts of energy
THIS is a sheet or band of fibrous connective tissue that is deep to the skin and surrounds muscles and other organs of the body
what is fascia
THIS is used at the neuromuscular junction to trigger the firing of motor neurons and is released into the synaptic cleft when an action potential arrives at a neuron's axon terminal
what is acetylcholine
THIS is used to break down acetylcholine and limits the duration of muscle stimulation
acetylcholinesterase
THIS is most of the skeletal muscles in the body, because they can reach peak twitch tension in 0.01 seconds or less after stimulation; large in diameter, densely packed myofibrils, powerful contractions. (white muscles)
what is fast fibers
oxygen consumption after exercise (aerobic metabolism) converts lactate into THIS
what is pyruvate
if the connective tissue layers extend beyond the muscle to form a rope-like structure it is called a THIS, if they form a flat sheet it is called an aponeurosis
what is tendon
THIS unit consists of a somatic motor neuron and all the muscle fibers it controls
what is motor unit
in isotonic contraction, tension is increasing while the muscle changes length; in THIS contraction, muscle contracts but does not change in length (the tension never exceeds the load)
THIS relates the tension produced by the entire muscle fiber to the length of individual sarcomeres
what is the length-tension relationship
extra oxygen used to pay back or restore metabolic conditions is called THIS; it is why you continue to breathe heavily after stopping exercise
the goal of THIS theory is to overlap actin and myosin (in the sarcomere)
what is sliding filament theory
THIS occurs as the passage of an action potential along a T tubule triggers the release of Ca2+ from the cisternae of the SR at triads; it uses calcium ions to remove contracting inhibitor and joins actin & myosin
in concentric isotonic contraction, the length of muscle shortens and muscle tension exceeds the load (the object is moved); in THIS isotonic contraction, the length of muscle gets longer and muscle tension is less than load
what is eccentric
THIS is when all motor units contract in complete tetanus
what is peak tension
the three layers of connective tissue in skeletal muscle tissue are THESE
what is epimysium, perimysium, and endomysium
the terminal cisternae, found in THIS, is where you would find the greatest concentration of calcium ions in a resting skeletal muscle fiber
what is sarcoplasmic reticulum
THIS occurs when a 2nd action potential triggers muscle contraction before the first contraction has finished; hint: ocean
what is wave summation
unfused/incomplete tetanus is almost at maximum tension; it is sustained but wavering contraction. fused/complete tetanus eliminates THIS phase, and individual twitches cannot be detected
THIS contraction is a brief contraction of all muscle fibers in a motor unit response to a single action potential
what is twitch contraction
