Here's how it works:
* Sensory input: The nervous system receives information about the body's position, environment, and desired movements from sensory organs like eyes, ears, and muscles.
* Integration: The brain and spinal cord process this sensory information, making decisions about how to move.
* Motor output: The nervous system sends signals through motor neurons to muscles, triggering contractions that produce movement.
Key components involved:
* Brain: The central control center, responsible for planning, coordinating, and initiating movements.
* Spinal cord: Relays signals between the brain and the rest of the body, and also controls some reflexes.
* Sensory neurons: Carry signals from sensory organs to the central nervous system.
* Motor neurons: Carry signals from the central nervous system to muscles.
* Muscles: The tissues that contract to produce movement.
Examples of coordinated movements controlled by the nervous system:
* Walking: A complex sequence of muscle contractions coordinated by the brain and spinal cord.
* Swimming: The synchronized movements of limbs and body controlled by the nervous system.
* Flying: The intricate adjustments of wing movements by birds and insects.
* Catching a ball: Rapid adjustments in hand position and movement guided by visual input and processed by the nervous system.
