Benjamin Cummings. InterActive Physiology®
8-System Suite CD-ROM, Benjamin Cummings, 2004.
Objective:
To describe in short essays or
diagrams the anatomical organization of muscle cells and the neuromuscular
junction and to explain how nervous stimulation causes muscle contraction, at
the level of 85% proficiency for each student.
In order to achieve this objective, you will need to be able
to:
- Describe the basic anatomical features of skeletal muscle
and skeletal muscle cells.
- Describe the organization of the neuromuscular junction;
and explain the role of motor neurons in causing the contraction of a
muscle cell.
- Explain the sequence of events at the neuromuscular
junction that follow stimulation of a nerve.
- Describe the molecular structure and functional features
of thin filaments and of thick filaments.
- Explain the sequence of events that occur in single cross
bridge cycle, including the role of ATP and calcium.
- Explain the sequence of events that occur in multiple
cross bridge cycling.
