How is the muscular contraction stopped (i.e.: how does a muscle relax after contraction)? 1. The brain stops sending the nerve impulse that commands the muscle to contract, interrupting communication at the neuromuscular junction 2. Acetylcholineesterase (AChE) is released into the synaptic cleft to destroy any remaining Acetylcholine 3. No mechanism is necessary. When the antagonist begins to contract, it forces relaxation and stretch of the agonist muscle. 4. Relaxation occurs as the myosin heads are "snapped" off of the thick filaments. This interrupts the crossbridge and allows for muscles to stretch 5. Relaxation only occurs if the brain sends a "stop" signal to the muscle
Musculoskeletal System
The musculoskeletal system, also called the locomotor system, is an organ system that gives humans and animals the ability to move using their muscular and skeletal systems. It provides stability, form, support, and movement to the body. The skeleton is composed of bones (skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system is subdivided into two broad systems, such as the muscular system and the skeletal system.
Skeletal structure
The skeletal system is the core framework of the human body. The skeletal structure comprises bones and connective tissue, including cartilage, ligaments, and tendons. The skeletal structure of our body acts as a support structure. It maintains the body's shape and is responsible for its movement, blood cell formation, protection of organs, and mineral storage. The skeletal system is referred to as the musculoskeletal system.
