Which body system is responsible for detecting sensations and controlling movement?

The body system responsible for detecting sensations and controlling movement is the nervous system. This system plays a crucial role in both receiving sensory information from the environment and orchestrating appropriate responses to that information through voluntary and involuntary actions. Sensory receptors throughout the body detect stimuli such as touch, pain, temperature, and pressure, and relay this information to the brain. The brain then processes this information and sends signals through motor neurons to muscles, leading to movement.

The nervous system is divided into the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), consisting of nerves that branch out to the rest of the body. Together, these components facilitate rapid communication between different parts of the body, ensuring that organisms can respond to their environment effectively.

This function is distinct from other systems like the endocrine, skeletal, and circulatory systems. The endocrine system primarily regulates bodily functions through hormones, the skeletal system provides structure and support, and the circulatory system is responsible for transporting blood, nutrients, gases, and wastes throughout the body. None of these systems directly detect sensations or control movement in the way the nervous system does.
