NCERT Solutions For Class 11 Biology Neural Control and Coordination pdf is provided here for better understanding and clarification of the chapter.
Neurons are highly specialised cells in all animals which help in detecting, receiving and transmitting of the signals. Central nervous system (CNS) and peripheral nervous system (PNS) are two divisions of brain in human body. Signals from organs or tissues is transmitted to CNS it is done through afferent nerve fibres. Whereas the impulses from CNS to organs is transmitted through efferent fibres. The parts of neuron are: Dendrites, cell body, nucleus, Nissl's granules, Schwann cell, Axon, Myelin sheath, Node of Ranvier, Axon terminal, Synaptic knob.
