Effectors are muscles or glands which work in response to the stimulus received from the motor nerves.
A musculoskeletal system (also known as the locomotor system) is an organ system that gives animals (and humans) the ability to move using the muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body.
It is made up of the body’s bones (the skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system’s primary functions include supporting the body, allowing motion, and protecting vital organs. The skeletal portion of the system serves as the main storage system for calcium andphosphorus and contains critical components of the hematopoietic system.
This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons andligaments. The bones provide the stability to a body in analogy to iron rods in concrete construction. Muscles keep bones in place and also play a role in movement of the bones. To allow motion, different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly on to each other. Muscles contract (bunch up) to move the bone attached at the joint.
