Document Summary
Chapter 3: the nervous system has the responsibility of co-ordinating the activity of all the other systems, the cells of the nervous system branch out like a vast cable network throughout our bodies. This network is organized in tiers or levels. This organization plan is called a hierarchy: structures on the top level direct the activity of structures at lower levels. The peripheral nervous system or pns can be divided into two branches, the somatic and the. The somatic branch contains all those nerves that send messages from the brain to the muscles for example, and relay messages from the body (e. g. , skin) back to the brain. Autonomic nervous system is responsible for controlling the activity of our internal organs. This system operates automatically - we don"t need to think for our heart to beat, our lungs to breathe, or our stomachs to digest.
