Sensory Systems and Receptors

This video provides an overview of the sensory systems, which are part of the nervous system responsible for processing sensory information. It covers the components of sensory systems, including sensory receptors, neural pathways, and brain regions. The video explains how sensory receptors respond to stimuli and convert them into nerve impulses. It also discusses different types of sensory receptors, such as mechanoreceptors, chemoreceptors, photoreceptors, and nociceptors, and classifies them based on the source of stimuli. Finally, it describes neural pathways and the main sensory areas of the brain.
