These two systems work together and respond to homeostasis - ANSWER Nervous and endocrine Chemical signal from nervous - ANSWER Sends message along nerve fiber that releases a chemical message directly to a target organ Chemical signal from endocrine - ANSWER Uses blood to send a hormone to a target organ- slower acting but long lasting. Planaria - ANSWER Movement is the only function of the nervous system in this organism Two lateral nerve cords joined by transverse cords- ladder like - ...
