ANATOMY

Detailed explanation-1: -olfactory system, the bodily structures that serve the sense of smell. The system consists of the nose and the nasal cavities, which in their upper parts support the olfactory mucous membrane for the perception of smell and in their lower parts act as respiratory passages.

Detailed explanation-2: -Your ability to smell comes from specialized sensory cells, called olfactory sensory neurons, which are found in a small patch of tissue high inside the nose. These cells connect directly to the brain. Each olfactory neuron has one odor receptor.

Detailed explanation-3: -Olfaction, the sense of smell detects and discriminate odors as well as social cues which influence our innate re-sponses.

Detailed explanation-4: -The olfactory nerve is a solely sensory nerve and conveys the sense of smell. Its receptors are located in the olfactory mucosa under the roof of the nasal cavity. The olfactory fibers cross the skull base through the olfactory foramina of the cribriform plate and enter the olfactory bulb in the olfactory groove.

Detailed explanation-5: -Your nose is part of your respiratory system. It allows air to enter your body, then filters debris and warms and moistens the air. Your nose gives you a sense of smell and helps shape your appearance.
