pairs of nerves branch from the CNS. 12 of the pairs branch from the brain and the other 31 nerve pairs branch from the spinal cord. The 43 pairs of nerves stretch throughout the body to form the peripheral nervous system. The CNS is the coordinator and “decision maker” in the nervous system‚ and the PNS is sending the information as sensory input and receives instructions as motor output to muscles and glands. The autonomic nervous system has some elements in the CNS and it shares some nerves with

Adaptation As the world constantly changes‚ the brain and nervous system allow a person to adjust to those changes. The brain has a lot of plasticity‚ meaning it has a vast capacity for modification and change. 4.

brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS is made up of nerves that branch out from the spinal cord

fingers between your door‚ are all painful accidents. Pain is the undesirable feeling; the red alert which signals our attention to something unfavorable happening to our bodies. Our bodies can detect pain by nocioceptors. Nocioceptors are special nerve receptors designed for stimuli that are encountered as painful (Benjamin B. Lahey‚ 2009). There are two significant pathways these neural pain messages travel to our brain; fast and slow. The fast and slow pathways are the reason why our bodies
