Neural Control and Coordination
A touch, a thought and a reflex all travel as electrical signals. This chapter in NCERT Class 11 Biology, Chapter 18, explains neurons, resting and action potentials, synaptic transmission, and the human brain, spinal cord and peripheral and autonomic nerves. It traces how eyes, ears, nose, tongue and skin send sensory input and how reflex arcs protect the body. You will learn the parts of the forebrain, midbrain and hindbrain and how coordination keeps posture, balance and response precise.
