Functional Anatomy: Musculoskeletal Anatomy, Kinesiology and Palpation for Manual Therapists (First Edition) Lesson Plans Chapter 3 — Myology Goals of the Lesson: Cognitive: Students will be able to identify types of muscle tissue, skeletal muscle functions, and muscle fiber arrangements. They will be able list and explain the six factors that make up muscle names. Students will be able to explain the five muscle properties and identify major structures of macroscopic and microscopic muscle anatomy. They will be able to explain the steps of how an action potential leads to contraction and list and describe four factors that affect force production. Students will be able to explain the differences between slow twitch, fast twitch, and intermediate muscle fibers and how they are distributed. They will be able to list and explain types of muscle contractions, muscle relationships, levers in the human body, proprioceptors, and types of range of motion. They will be able to identify major muscles of the body. Motor: Students will be able to demonstrate active, passive, and resisted range of motion.
