What is the three main functions of the nervous system?

1. Sensory function: The nervous system receives information from the body's internal and external environments through sensory receptors. This information is then transmitted to the brain and spinal cord for processing.

2. Integrative function: The nervous system processes and integrates the sensory information received, allowing the body to make decisions and respond appropriately to stimuli. This function involves the coordination of various body systems and the regulation of bodily functions.

3. Motor function: The nervous system sends signals to muscles and glands to initiate responses to stimuli. This allows the body to move, react, and perform various actions in response to the information received from the environment.

1. Sensory function: Detecting changes in the internal and external environment and converting them into nerve impulses.
2. Integrative function: Processing and interpreting sensory information and making decisions about appropriate responses.
3. Motor function: Sending commands to muscles and glands to produce responses.
