♥This week, I have learned about the "Nervous System."♥
♥Nervous system is divided into two , Central Nervous System(CNS) and the Peripheral Nervous System(PNS). The CNS refers to the brain and the spinal cord while the PNS refers everything outside the brain and spinal cord. PNS is also divided into two, the Somatic or voluntary and the Autonomic. Autonomic is also divided into two, parasympathetic and sympathetic branch. Neuroglia and Neurons are in the part of Nervous tissue, neuroglia are specialized cells that allows nervous system to perform an action while the neurons is the group of cells which carries the control function of the nervous system. I also knew that the spinal cord as 31 segments, each with a pair of spinal nerves, The spinal nerves are parts of the peripheral nervous system.♥
♥My suggestion for this lesson is don't take this lesson very fast, I mean we need to focus on this section, its not just easy to understand. Please explain very well especially the reporter didn't explain well the whole topic. I hardly understand.♥
