6. What are the three connective tissue layers we discussed in class and what
part of the muscle do they wrap surround?

9. Muscle fiber is the same thing as a _________________ ___________
10. Be able to describe the microscopic anatomy (structure) of a muscle fiber
a. Sarcolemmab. Myofibrilsc. Sarcoplasmic reticulum
11.Myofibrils are aligned to give distinct bands. What are these two bands
and what are they made of?
12.Thick filaments are composed of the protein _______________
13.Thin filaments are composed of the protein ________________
14.The thin filaments are anchored to the ____________________

_________________________________
16.Muscle cells must have the following four things in order to both contract
and return to their normal resting state. Describe each one
a. Excitabilityb. Contractilityc. Extensibilityd. Elasticity-
17. Skeletal muscles are stimulated by a ____________________
________________.
18. One motor neuron and ALL the skeletal muscle cells stimulated by that
neuron is called a _____________________ __________________
19. The junction between the axon terminal and the muscle it is stimulating is
called the _____________________________________________
__________________
20. Once an action potential reaches the axon terminal,
_________________________ are released in order to continue the action
potential through the muscle to cause contraction
21. The specific neurotransmitter involved in skeletal muscle contraction is
_________________________________, sometimes abbreviated ________
22. ACh attaches to receptors on the ____________________________ of the
muscle cell causing ________________ channels to open. This allows the
action potential to continue into the muscle cell.
