- Discuss the following statement: “The basal lam-ina of muscle fibers serves as a molecular bulletin board,in which adjoining cells can post messages that direct thedifferentiation and function of the underlying cells.”If ligand-gated K+ channels were to open in an unstimulated muscle fiber,how would this affect the resting membrane potential?High blood K+ concentrations cause depolarization of the restingmembrane potential. Predict and explain the effect of high blood K+levels on smooth muscle function
- Name and describe the function of the two regulatory proteins on the actin thin filament muscle.Explain the intracellular mechansim of smooth muscle relaxation of agaonist such as mepyrimine and atropine. Give diagram for each.Put these events that occur in skeletal muscle in the correct chronological sequence: 1. Activation of voltage-gated dihydropyridine (DHP) receptor in the T-tubule 2. Opening of mechanically-gated ryanodine receptors (RyR) on the sarcoplasmic reticulum 3. Na+ influx through ligand-gated ion channels on the motor end plate 4.

- Muscle spindle structures consist of: Extrafusal muscle fibers and gamma motor neurons Extrafusal muscle fibers and alpha motor neurons Golgi tendon organs and gamma motor neurons Intrafusal muscle fibers and gamma motor neuronsIf ACh channels are opened on a muscle fiber that is held at +55 mV, which ion moves predominantly? In which direction does this ion move across the muscle cell membrane?In what ways does the neural control of smooth muscle activity differ from that of skeletal muscle? Describe how a stimulus may lead to the contraction of a smooth muscle cell without a change in the plasma membrane potential. Describe the differences between single-unit and multiunit smooth muscles. cite your references
- Define what the NMJ is and why it's important for muscle contraction. Explain in short the process of the NMJ signaling the muscle to contract. Note the difference between a motor unit and the NMJ.*When dynamic y-motor neurons are activated at the same time as a-motor neurons to muscle, [A] prompt inhibition of discharge in spindle la afferents takes place. [B] clonus is likely to occur. [C] the muscle will not contract. [D] the number of impulses in spindle la afferents is smaller than when a discharge alone is increased. [E] the number of impulses in spindle la afferents is greater than when a discharge alone is increased.Give the diagram of a sarcomere of skeletal muscle showing different regions?
