Human Nervous System Notes:
The nervous system is a very intricate part of an animal that manages its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system senses the environmental changes that impact the body and then responds to these events with help of endocrine system. In vertebrates it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the spinal cord and brain. The PNS consists mainly of nerves, which whihc connect the CNS to all other parts of the body.
