Answer 1

• 6.The primary role of the Central Nervous System is to Integrate information from the periphery and coordinate responses.
• The central nervous system is responsible for integrating sensory information and responding accordingly. It consists of two main components:
• The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.
• The brain is responsible for integrating most sensory information and coordinating body function, both consciously and unconsciously. Complex functions such as thinking and feeling as well as regulation of homeostasis are attributable to different parts of the brain.
• 9.Activation of the Sympathetic Nervous System produces increase in heart rate,and activation of the Parasympathetic Nervous System produces decrease in the heart rate.
• The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate.
• 10.In cases of autoimmunity the immune system,begins to attack the body
• Autoimmunity occurs when the immune system automatically launches an inflammatory response against your own body. In cases of immune system over activity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections.In response to an unknown trigger, the immune system may begin producing antibodies that instead of fighting infections, attack the body's own tissues.
