[amp_mcq option1=”Nerves from eyes to CNS” option2=”Nerves from ears to CNS” option3=”Nerves from skin to CNS” option4=”All of the above” correct=”option4″]<\/p>\n
The correct answer is D. All of the above.<\/p>\n
The peripheral nervous system (PNS) is the part of the nervous system that lies outside the brain and spinal cord. It consists of nerves that connect the CNS to the rest of the body, including the skin, muscles, and organs. The PNS is divided into two parts: the somatic nervous system and the autonomic nervous system.<\/p>\n
The somatic nervous system controls voluntary movement. It consists of nerves that carry signals from the brain and spinal cord to the muscles, allowing us to move our bodies.<\/p>\n
The autonomic nervous system controls involuntary functions, such as heart rate, breathing, and digestion. It consists of two divisions: the sympathetic nervous system and the parasympathetic nervous system.<\/p>\n
The sympathetic nervous system is activated in response to stress or danger. It causes the heart to beat faster, the breathing to become faster, and the pupils to dilate.<\/p>\n
The parasympathetic nervous system is activated when the body is at rest. It causes the heart to beat slower, the breathing to become slower, and the pupils to constrict.<\/p>\n
The PNS is essential for our ability to interact with the world around us. It allows us to move our bodies, sense our environment, and control our internal organs.<\/p>\n","protected":false},"excerpt":{"rendered":"
