Muscular System Physiology: Quiz Questions – Chapter 9, Week 4

Summary

The muscular system is studied. Students get questions on muscle types, functions, and anatomy. They get to test their knowledge of muscle physiology and gross anatomy.

Muscle functions and types

Muscle functions are described. Students learn about the three types of muscle tissue. They answer questions on muscle structure and contraction.

Excitation-contraction coupling

The process of excitation-contraction coupling is explained. Students answer questions on how muscles contract. They learn about the role of calcium ions and cross-bridges.

Muscle anatomy and movement

Muscle anatomy is described. Students learn about specific muscles and their actions. They answer questions on muscle origins, insertions, and functions.

Levers and muscle groups

Levers and muscle groups are explained. Students answer questions on how muscles work together. They learn about the role of muscle groups in specific movements.

Key terms

Skeletal muscle

Muscle that is attached to bones and is responsible for movement.

Smooth muscle

Muscle found in the walls of hollow organs, such as the stomach and intestines.

Cardiac muscle

Muscle found in the heart that pumps blood throughout the body.

Hypertrophy

An increase in the size of muscle fibers, often due to weight lifting.

Action potential

An electrical signal that travels along a nerve cell or muscle fiber.

Isotonic contraction

A type of muscle contraction where the muscle produces tension, but the length of the muscle is increasing.
