the gap between the motor neuron and the muscle fiber it supplies is called the ______
______ is a metabolic pathway that produces water, carbon dioxide, and ATP, and provides for a large amount of ATP per glucose because oxygen is used
the muscle tissue that consists of single, very long, cylindrical, mulitinucleate cells with very obvious striations is
skeletal muscle only
which of the following groupings is INCORRECT
striated muscle, cylindrical cells, attached to the skeleton, involuntary
an elaborate network of membranes in skeletal muscle cells that function in calcium storage is the
the major function of the sarcoplasmic reticulum in muscle contraction is to
regulate inracellualr calcium cencentration
after nervous stimulation of the muschle cell has cease, the calcium:
is reabsorbed into the sarcoplasimic reticulum
creatine phosphate functions in the muscle cells by
storing energy that will be transferred to ADP to resynthesize ATP as needed
the fondition of muscle fatigue can be best explained by:
insufficient intracellular quantities of ATP due to excessive consumption
observe the list of muscle actions below, wheich fo them whould NOT be classified as ISOTONIC contraction
pushing against a stationary wall
muscle tone is
a state of sustained partial muscular contraction that is vital for the health of muscles
skeletal muscle is called involuntary because it is the only typw of muscle usually subject to conscious contryl (T/F)
a nerve cell and all the muscle cells that it stimulates are referred to as a motor end plate (T/F)
a contraction in which the muscle does not shorten but its tension increses is called isometric (T/F)
the neurotransmitter used by the nervous system to activate skeletal muscle cells is acetylcholine (T/F)
