Nose (Olfactory System)
The nose is responsible for the sense of smell, also known as olfaction. It allows us to detect and identify different odors in our environment. The olfactory system begins with the nasal cavity, which is lined with specialized olfactory receptor cells. These receptor cells have hair-like structures called cilia that extend into the nasal cavity. When airborne odor molecules enter the nose, they bind to specific receptors on the cilia, triggering a chemical reaction. This reaction generates electrical signals that are transmitted to the olfactory bulb, located at the base of the brain. The olfactory bulb processes these signals and sends them to other regions of the brain, allowing us to perceive and interpret different smells.
List of Five Sense Organs and Their Functions
Five Sense Organs and their Functions: Sense organs play a vital role in the survival and well-being of organisms. Sense organ help detect potential threats, locate food sources, navigate the environment, communicate with others, and experience the world around them. Sense organs play a fundamental role in the organism’s daily life. By gathering sensory information, organisms can adapt to their surroundings and engage in appropriate behaviors for survival, reproduction, and overall functioning. In this article, we will discuss the five sense organs and their functions with labeled diagrams.
