Musculoskeletal System—Physiology and Physics of the Muscles
Lecture no. 28 from the course: Understanding the Human Body: An Introduction to Anatomy and Physiology, 2nd Edition
Taught by Professor Anthony A. Goodman | 44 min | Categories: The Great Courses Plus Online Science Course
In this lecture, we will examine the physiology and physics of the muscles. There are three kinds: skeletal, smooth, and cardiac. The muscles are innervated by motor neurons, which stimulate them to contract. Nerves connect with target muscles by means of a neurotransmitter, which conducts the electrical stimulation from the nerve to the muscle across the synaptic gap. The lecture concludes by examining the physics of muscle contraction.
