Chapter 21 – Neural Control And Coordination
Neural Control and Coordination is an important chapter in Class 11 Biology that explains how the human nervous system controls and coordinates body activities. The nervous system helps the body respond to internal and external stimuli quickly and efficiently.
This chapter describes the structure and function of neurons, the basic units of the nervous system, and explains how nerve impulses are generated and transmitted. It covers the organization of the central nervous system (CNS)—brain and spinal cord—and the peripheral nervous system (PNS). The structure and functions of different parts of the brain such as the cerebrum, cerebellum, and medulla oblongata are discussed in detail.
The chapter also explains the reflex action and reflex arc, and introduces the sense organs including the eye and ear, describing how vision and hearing occur. Understanding neural control is essential for mastering human physiology and is highly important for CBSE board exams and NEET preparation.
