Learning Objectives
- Describe the functions of skeletal muscle
- Describe the neural events that control skeletal muscle contraction
- Describe the key steps involved in muscle contraction: excitation-contraction coupling and cross-bridge cycling (sliding filament theory)
- Describe the key steps in skeletal muscle relaxation
- Identify the types of smooth muscle and how they are controlled
- Describe the contraction mechanism of smooth muscle
- Delineate the key differences between smooth and skeletal muscle function
Skeletal Muscle
- what are the functions of skeletal muscle?
- what is a neuromuscular junction?
- chemical communication is required for [parts of contraction]?
- how do axon termini and motor end plates facilitate communication?
- why is the shape of T-tubules important for muscle contraction?
- what are the different types of troponin? what are their functions?
Skeletal Muscle Contraction
- what are the steps of excitation-contraction coupling?
- what are the 2 ways by which DHP-Rs activate RYRs?
- how does $\small\ce{Ca^{2+}}$ interact with the troponin-tropomyosin complex?
