Step-by-Step Guidance for BSC 2086 – Chapter 12: Muscle Physiology Study Questions

Q1. What are the three types of muscle tissue, and how do they differ in structure and function?

Background

Topic: Types of Muscle Tissue

This question tests your understanding of the classification of muscle tissues and their unique structural and functional characteristics.

Key Terms:

• Skeletal muscle

• Cardiac muscle

• Smooth muscle

Step-by-Step Guidance

1. List the three main types of muscle tissue found in the human body.

2. For each type, describe its basic structure (e.g., striated or non-striated, multinucleated or single nucleus, voluntary or involuntary control).

3. For each type, explain its primary function and where it is typically found in the body.

4. Compare and contrast the three types, focusing on how their structure relates to their function.

Q2. Which muscle type is controlled by the somatic nervous system?

Background

Topic: Muscle Control Mechanisms

This question assesses your knowledge of how different muscle types are regulated by the nervous system.

Key Terms:

• Somatic nervous system

• Voluntary control

Step-by-Step Guidance

1. Recall which muscle types are under voluntary versus involuntary control.

2. Identify which branch of the nervous system (somatic or autonomic) controls voluntary movements.

3. Match the muscle type to the appropriate nervous system control.

Q3. Which muscle types are controlled by the autonomic nervous system?

Background

Topic: Muscle Control Mechanisms

This question focuses on your understanding of involuntary muscle control and the role of the autonomic nervous system.

Key Terms:

• Autonomic nervous system

• Involuntary control

Step-by-Step Guidance

1. Review which muscle types are not under conscious (voluntary) control.

2. Recall the functions of the autonomic nervous system.

3. List the muscle types regulated by the autonomic nervous system.

Q4. Why are muscle cells considered “excitable cells”?

Background

Topic: Excitability of Muscle Cells

This question tests your understanding of the electrical properties of muscle cells and their ability to respond to stimuli.

Key Terms:

• Excitability

• Action potential

• Membrane potential

Step-by-Step Guidance

1. Define what it means for a cell to be "excitable."

2. Explain how muscle cells respond to electrical or chemical stimuli.

3. Describe the role of action potentials in muscle contraction.

Q5. Why is muscle considered a high-energy-demanding tissue?

Background

Topic: Muscle Metabolism and Energy Demand

This question examines your understanding of why muscle tissue requires large amounts of energy, especially during contraction.

Key Terms:

• ATP (adenosine triphosphate)

• Muscle contraction

• Metabolic activity

Step-by-Step Guidance

1. Identify the main energy molecule used by muscle cells.

2. List the processes in muscle contraction and relaxation that require energy.

3. Explain why these processes make muscle tissue highly energy-demanding.
