The video tutorial explains the maintenance of posture through coordinated muscle contractions, focusing on the myotatic reflex, an involuntary muscle contraction triggered by stretching. It details the role of neuromuscular spindles in generating nerve signals, which are transmitted as electrical impulses to the spinal cord. The process involves sensory neurons, motor neurons, and the release of neurotransmitters like acetylcholine at the neuromuscular junction, leading to muscle contraction. The tutorial provides a comprehensive overview of the reflex arc and its components.
