8.1. The types of responses

Stimulus and response

As we saw in the topic "The nervous system", we relate to the environment that surrounds us, receiving information from our environment, integrating it, preparing a response and making that response. Thus, we adapt to the different circumstances that surround us and we can live.

The nervous system is responsible for emitting this response, which is carried out by the effector organs (muscles and endocrine glands). There are two types of responses:

  • Muscular response: there is a movement in which the locomotor system or the viscera intervenes. These responses are short and short-lived. Two types of muscular response are distinguished:
  • Glandular response: the endocrine glands release chemicals (hormones) that act on the target organs. This response is slow and its action can be very long-lasting.

Game: You can practice with Pavlov's dogs on the Nobel Prize website.
