nervous vs endo
| Question | n | e |
|---|---|---|
| type of message being sent | electrochemical impulse initiated by cns | chemical signals (hormones) secreted from endocrine glands |
| pathway of message | uses neurons to carry impulse | uses blood vessels to carry hormone to effectors |
| speed of response | very rapid, measured in milliseconds | seconds to hours, slower |
| specificiy | localised - can be as specific as single muscle | speciific tissue but all of that type, all with receptor |
| duration of response * | short lived & end when impulse are no longer being sent - last seconds | short lived or lasts months to years |
