Motor unit

The tutorial explores how muscles and nerves collaborate to enable movement, focusing on the motor unit, which includes a motor neuron and the skeletal muscle fibers it innervates. It covers the anatomy and function of motor neurons, the structure of skeletal muscles, and the role of sarcomeres in muscle contraction. The video also discusses actin accumulation myopathy, a disorder affecting muscle contraction. The tutorial concludes with a summary of the key points covered.
