Answer 1

1. The nervous system of the body is responsible for electrochemical communication. The nerve cells or neurons carry the electrical impulses and help in the stimulation and transmission of neural messages.

2. Neural Plasticity refers to the ability of the brain to change and reorganize itself by forming new connections. This capacity enables the brain to modify and adapt throughout life.

3. The Central Nervous System (CNS) is composed of the Brain and Spinal Cord. While the Peripheral Nervous System (PNS) consists of the nerves that connect the brain and the spinal cord to other parts of the body. PNS is composed of Somatic Nervous System and Autonomic Nervous System.

4. The autonomic nervous system acts as the control system of the body that is responsible for regulating the heart rate, respiratory rate, digestion, urination, and sexual arousal. The autonomic nervous system is made up of the Sympathetic Nervous System(SNS) and the Parasympathetic Nervous System (PNS).

5. The sympathetic nervous system (SNS) is part of the autonomic nervous system (ANS), which also includes the parasympathetic nervous system (PNS). The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response. The SNS activates the release of norepinephrine in the reaction. Consequently, the sympathetic nervous system can accelerate heart rate, widen bronchial passages, constrict blood vessels, increase peristalsis in the oesophagus, cause goosebumps, perspiration, and raise blood pressure.
