Explain the movement of ions into, out of, and within the muscle fber after Acetylcholine (ACh) binds into the sarcolemma.

Define the three classes of motor units and their role in muscle innervation

Explain how a slight (but smooth) contraction differs from a vigorous contraction of the same muscle. Use the concepts of multiple motor unit summation.

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 neurons

Describe the Neural excitation of the muscle and Describe how a signal arriving at the axon terminal results in calcium being released from the Sarcoplasmic reticulum

Match the following types of contractions: The stimulus above which no stronger contraction can be elicited, because all motor units are firing in the muscle Determined by alternating motor units of a muscle organ even when the muscle is at rest Continued sustained smooth contraction due to rapid stimulation The situation in which contractions become stronger due to stimulation before complete relaxation occurs How a smooth increase in muscle force is produced [Choose] [Choose ] [Choose] [Choose] [Choose]

Without acetylcholine esterase (AChe) will the action of skeletal muscle increase, decrease or not change? Why?

Explain in detail  cholinergic/acetylcholine receptors and what role they plain in Smooth muscle contraction.  Provide intraceullar mechanism.

Describe the gross structure of a skeletal muscle.

Describe what would occur when the neuron stops releasing acetylcholine to the sarcolemma and the group of muscles would have the least amount of myofibers in each skeletal muscle motor unit?
