Q1. Discuss Nervous System in detail.
- Nervous system coordinates body's voluntary and involuntary actions, transmitting signals.
- CNS (brain, spinal cord) is the command center; PNS (nerves) links CNS to body.
- ANS (part of PNS) manages involuntary functions, divided into Sympathetic (fight-or-flight) and Parasympathetic (rest-and-digest).
- Neurons are functional units transmitting signals; Neuroglia support and protect neurons.
Answer: The nervous system is the body's intricate control, communication, and information processing network, fundamental to all physiological and psychological functions. It acts as a sophisticated electrical wiring system, coordinating both voluntary and involuntary actions, and enabling the transmission of signals throughout the organism. This complex system is broadly divided into two main components: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS), each with distinct roles...
