chapter 7 the nervous system
you are driving down the freeway when a horn blares on your right, and you swerve to your left. you are with a group of friends but are not paying attention to any particular conversation, yet when you hear your name, you immediately focus in. what do these events have in common? they are everyday examples of nervous system function, which has your body cells humming with activity nearly all the time.
the nervous system is the master control and (1 ) system of the body. every thought, action, and emotion reflects its activity. it communicates with body cells using electrical impulses, which are rapid and specific and cause almost immediate responses.
the nervous system does not work alone to (2 ) and maintain body homeostasis, the endocrine system is a second important regulating system. whereas the nervous system controls with rapid electrical nerve impulses, the endocrine system produces hormones that are released into the blood. thus, the (3 ) system acts in a more leisurely way. we will discuss the endocrine system in detail in chapter 9.
to carry out its normal role, the nervous system has three overlapping functions (figure 7.1, p. 226): (1) it uses its millions of (4 ) receptors to monitor changes occurring both inside and outside the body. these changes are called stimuli, and the gathered information is called sensory input. (2) it processes and interprets the sensory input and decides what should be done at each moment—a process called integration. (3) it then causes a response, or effect, by activating muscles or glands (effectors) via (5 ) output

Explanation:

The nervous system is a master control and communication system. It works with the endocrine system to regulate and maintain homeostasis. It has sensory receptors for input and causes responses via motor output.
