Final answer:

The nervous system and endocrine system are two communication systems in the body with distinct differences in how they operate and the processes they control.

  1. Differences between the nervous system and endocrine system:
    • The nervous system uses electrical impulses while the endocrine system uses hormones for communication.
    • The nervous system responds rapidly while the endocrine system's responses are slower but longer-lasting.

    • The nervous system includes the brain, spinal cord, and nerves, while the endocrine system comprises glands that secrete hormones.
