Scientific Objections: Even on the purely biological plane there is a wide, unbridgeable chasm between man and beast, as illustrated by the following four considerations: 1  The human brain possesses qualities [G2, p. 115â130] that have no parallel in the animal world. One consequence is manâs explicit mental capabilities.
Olfactory System. The olfactory system is responsible for our sense of smell. This sense, also known as olfaction, is one of our five main senses and involves the detection and identification of molecules in the air. Once detected by sensory organs, nerve signals are sent to the brain where the signals are processed. Our sense of smell is closely linked our sense of taste as both rely on the perception of molecules. It is our sense of smell that allows us to detect the flavors in the foods we eat. Olfaction is one of our most powerful senses. Our sense of smell can ignite memories as well as influence our mood and behavior. Olfactory System Structures. Our sense of smell is a complex process that depends on sensory organs, nerves, and the brain. Structures of the olfactory system include:
Smell and Taste Disorders (Chemosensory Disorders) The Senses of Smell and Taste The senses of smell and taste are chemosenses and belong in the chemical sensing system. The processes of smelling and tasting are complex. They begin when molecules are released by substances that stimulate the sensory cells in the nose, mouth, or throat. Olfactory nerve cells are stimulated by odors.
