📖 1. Sensory Receptors and Sense Organs

🔑 Key Concepts & Definitions

Sense organs: Specialized organs that detect stimuli from the environment, including eyes, ears, nose, tongue, and skin.

Sensory receptors: Cells within sense organs that receive and gather information from stimuli.

Seven sense organs: The complete set of human sense organs responsible for detecting various stimuli.

Specialized receptors in skin: Receptors that detect sensations such as warmth, cold, and pain.

Information gathering systems: Another term for sensory receptors emphasizing their role in collecting environmental data.

📝 Essential Points

Humans possess seven sense organs, five of which are responsible for collecting external stimuli: eyes for vision, ears for hearing, nose for smell, tongue for taste, and skin for touch-related sensations. Sensory receptors within these organs convert physical stimuli into neural impulses that are sent to the brain for processing. The skin contains specialized receptors that detect specific sensations like warmth, cold, and pain, broadening the range of sensory experiences humans can perceive.
