15. 9H: Olfaction - The Sense of Smell - Biology LibreTexts This page explains that human smell involves sensory receptors in the olfactory epithelium, where odorant molecules interact with receptors on sensory neuron cilia This interaction activates a signaling pathway that generates action potentials, allowing the brain to identify odors
Olfaction – Basic Human Physiology Trace the path of olfaction from the olfactory receptors, to the initiation of an action potential in the olfactory nerves, through the olfactory bulb, the olfactory tract, and to the various parts of the brain Like taste, the sense of smell, or olfaction, is also responsive to chemical stimuli
Olfaction - an overview | ScienceDirect Topics Olfaction refers to the sense of smell, a unique sensory modality that plays a crucial role in mating, survival, and shaping the quality of life in humans It involves the detection of chemical signals in our environment through a complex neuroanatomical structure and signaling cascades
The Olfactory System: Basic Anatomy and Physiology for General . . . Olfaction is one of the five basic human senses, and it is known to be one of the most primitive senses The sense of olfaction may have been critical for human survival in prehistoric society, and although many believe its importance has diminished
15. 2 Smell – Anatomy Physiology - Open Educational Resources Like taste, the sense of smell, or olfaction, is also responsive to chemical stimuli The olfactory receptor neurons are located in a small region within the superior nasal cavity (Figure 15 2 1) This region is referred to as the olfactory epithelium and contains bipolar sensory neurons
Olfactory system | Parts, Function, Organs | Britannica 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
Olfaction | definition of olfaction by Medical dictionary Called also olfaction The organs of smell are small patches of special cells (olfactory cells) in the nasal mucosa One patch is located in each of the two main compartments of the back of the nose The olfactory cells are connected to the brain by the first cranial nerve (olfactory nerve)
