In which type(s) of muscle cells does each cell have its own neuromuscular junction?                                 skeletal only                                 unitary smooth and skeletal                                 skeletal and cardiac       2. The follow is NOT true of CARDIAC muscle fibers:        - connected by gap junctions       -  include pacemaker cells that can produce produce action potentials at regular intervals without innervation        - without calcium cross bridge cycles will not occur and fibers will not shorten        - each cell in a motor unit has a neuromuscular junction with the same motor neuron                                 actin and myosin filaments are arranged in sarcomeres                                 produce greater force when stretched than at resting length   3. Match the following:   -Skeletal muscle   -Cardiac muscle   -Smooth muscle Can maintain prolonged isometric contractions with very little energy Striated muscle fibers with gap…

Smooth muscle cells have features that can be like Skeletal muscle, Cardiac muscle, or that can be unique to smooth muscle cells themselves. Match the 3 options below to the description of smooth muscle cells on the left. do NOT possess sarcomeres do NOT possess troponin or tropomyosin neurotransmitters and hormones regulate contraction different cells of the same muscle type can contract or relax in response to the 1. similar to skeletal muscle same neurotransmitter 2. similar to cardiac muscle possess gap junctions for coordinating contraction of multiple cells 3. unique to smooth muscle can generate contraction through an influx of Ca2+ across the plasma membrane use calmodulin and myosin light-chain kinase to start the cross-bridge cycle make use of motor units to control contraction >

One way to characterise biological tissue is to send a small electrical current through the tissue and measure the opposition to flow of that current through the tissue. In humans, the resistivity of fat is considerably greater than for muscle, which in turn is considerably greater than for blood and other body fluids. This can be used to analyse body composition, in particular, to estimate body fat percentage. (a) Using a simple model of fat versus non-fat tissue, draw a circuit diagram to represent the possible flows of current through the tissue. (b) Why would the analysis of body composition need to take into account the height and weight of the person? (c) How could the level of hydration or electrolyte abnormalities in the person affect the results of the analysis? DII Prt Scn a Home 9 F4 ES F6 F7 2$ & 4 6 7 8. 9
