The sequence of electrical changes that occurs along the sarcolemma when a muscle fiber is stimulated is known as the __________.
A
receptor potential
B
generator potential
C
resting membrane potential
D
motor end plate potential
E
action potential
Verified step by step guidance1
Understand that the sarcolemma is the cell membrane of a muscle fiber, and it plays a crucial role in conducting electrical signals.
Recognize that when a muscle fiber is stimulated, it undergoes a series of electrical changes that propagate along the sarcolemma.
Identify that these electrical changes are part of a process known as an action potential, which is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane.
Differentiate between the given options: receptor potential, generator potential, resting membrane potential, and motor end plate potential, noting that none of these specifically describe the sequence of electrical changes along the sarcolemma.
Conclude that the correct term for the sequence of electrical changes along the sarcolemma when a muscle fiber is stimulated is the action potential.
