Learning Target
o 10-4 Students can identify the components of the neuromuscular junction, and summarize the events involved in the neural control of the skeletal muscle contraction and relaxation.
Vocabulary
Neuromuscular junction
Excitation-contraction coupling
Contraction cycle
Excitation-contraction coupling
Contraction cycle
Checkpoints
Draw and label a series of pictures to describe the events that occur at a neuromuscular junction.
Draw and label a series of pictures to describe the events that occur during the contraction cycle.
What has to happen in order for muscles to relax?
How would a drug that blocks Ach release affect muscle contraction?
What would happen to a resting skeletal muscle if the sarcolemma suddenly became very permeable to Ca2+?
Predict what would happen to a muscle if the motor end plate failed to produce acetylcholinesterase.
