Chapter four of our textbook talked about the different ways that our body senses stimuli and the ways in which it reacts to them. It discussed in detail the different organs involved in these different processes and how they work, as well as different theories regarding uncertain information.
It began by discussing the principles involved in sensing stimuli and how our brain uses those stimuli to create perceptions and ideas. Not only did it discuss the known facts about this, but it also talked about ESP and other theories that people have put their faith in.
From here it went on to describe each of the senses - sight, hearing, taste, smell, touch - and the organs associated with them - eyes, ears, tongue, nose, receptors throughout the body. Once again, the authors not only talked about the known ways in which these organs function, but alsoabout the theories that have been discussed regarding controversial or unknown observations. They also talked about different disorders or problems that can arise when these organs are not functioning correctly and are not sending the brain signals regarding stimuli.
Overall, this chapter gives not only a good anatomical description of the human sense organs, but also some of the important terms and theories about how these organs function to help our brains interpret and react to the stimuli that we receive.
