Question 12 Answer:

The nervous system communicates with the brain using electrical impulses (via neurons) and neurotransmitters. These signals are fast - acting, short - lived, and targeted (specific neurons connect to specific areas). The endocrine system communicates with the brain (and the rest of the body) by releasing hormones into the bloodstream. Hormones are slower - acting, have longer - lasting effects, and are more widespread (they can affect many cells or organs throughout the body). Also, the endocrine system's communication is often part of a feedback loop (e.g., hormone levels are monitored and adjusted), while the nervous system's communication is more about rapid responses to stimuli.

Answer:

The nervous system communicates with the brain via electrical impulses (through neurons) and neurotransmitters, with fast, short - lived, and targeted signals. The endocrine system communicates by releasing hormones into the bloodstream, with slower, long - lasting, and widespread signals, often involving feedback loops.
