Summary
This section provides a comprehensive overview of the sensory systems that allow humans to detect and interpret environmental and internal stimuli. Key concepts include the different receptor types—chemo-, photo-, mechano-, and thermoreceptors—and the processes of sensation, perception, sensory adaptation, and integration. The anatomy and functioning of the senses of taste, smell, vision, hearing, and equilibrium are explained, emphasizing how the nervous system translates physical signals into meaningful experiences that maintain homeostasis.
