Coordination and Response | IGCSE and O Level Biology
This comprehensive IGCSE Biology presentation on coordination and response delves into the mechanisms that allow organisms to detect and react to stimuli. It explains how the nervous system—comprising the central nervous system (brain and spinal cord) and peripheral nervous system—transmits nerve impulses as electrical signals. The presentation covers key components like receptors, sensory neurones, interneurones, motor neurones, and effectors, with a detailed look at the reflex arc that underpins rapid, automatic responses. It also distinguishes between voluntary and involuntary actions, and explores synapses and neurotransmitter functions.
