Olfactory Nerve: Function, Disorders & Regeneration The olfactory nerve is responsible for your sense of smell and partially responsible for your sense of taste. It is also known as cranial nerve 1 because it is the shortest of the cranial nerves and one of only two nerves (the other is the optic nerve) that bypass the brain stem and connect directly to your brain.

- The receptor cells for the sense of smell (olfaction) in terrestrial vertebrates. are located in two clefts in the upper part of the nasal passages (See Figure. below). Unlike the receptor cells for taste, which are specialized receptor. cells, olfactory receptors are modified sensory neurons.

- 1 The olfactory bulbs has sensory receptors that are actually part of the brain which send messages directly to: 2  The most primitive brain centers where they influence emotions and memories (limbic system structures), and. “ Higher” centers where they modify conscious thought (neo-cortex).

The Olfactory Nerve The pathway for the Afferent fibers is the following (from the stimulatory cells in the periphery to the final synapse in the brain): The Olfactory Cells contain sensory nerve fibers that are alerted to the sense of smell.

Olfactory nerve The olfactory nerve (Latin: nervus olfactorius) is typically considered the first cranial nerve, or simply CN I. It contains the afferent nerve fibers of the olfactory receptor neurons, transmitting nerve impulses about odors to the central nervous system, where they are perceived by the sense of smell (olfaction).

- The olfactory nerve (Latin: nervus olfactorius) is typically considered the first cranial nerve, or simply CN I.esions to the olfactory nerve can occur because of blunt trauma, such as coup-contra-coup damage, meningitis, and tumors of the frontal lobe. They often lead to a reduced ability to taste and smell. However, lesions of the olfactory nerve do not lead to a reduced ability to sense pain from the nasal epithelium.

Olfactory nerve A08.800.800.120.640. The olfactory nerve, or cranial nerve I, is the first of twelve cranial nerves. The specialized olfactory receptor neurons of the olfactory nerve are located in the olfactory mucosa of the upper parts of the nasal cavity.he olfactory nerve is the shortest of all the twelve cranial nerves and only one of two cranial nerves (the other being the optic nerve) that do not join with the brainstem.

The Olfactory Nerve The Olfactory Nerve is the first of the Twelve Cranial Nerves. It consists of both afferent and efferent sensory fibers. The word Afferent means toward the centre, as in from a peripheral area of a limb to the central nervous system. The Olfactory Cells contain sensory nerve fibers that are alerted to the sense of smell. 2  There is a refractory period for each cell so certain areas of the Olfactory mucosa are stimulated each time a new smell enters the Nasal Cavity.

- After a smell enters the nose, it travels through the cranial nerve through the olfactory bulb, which helps the brain process smells. The olfactory bulb is part of the limbic system, the emotional center of the brain.

- Olfactory nerves. Also known as CN1, the olfactory nerve is the first of 12 cranial nerves located within the head. It relays sensory data to the brain, and it is responsible for the sense of smell. The nerve's olfactory receptors are located within the mucosa of the nasal cavity. Unlike many other nerves, CN1 does not possess two trunks. Rather, its sensory fibers extend through the ethmoid bone's cribriform plate, a part of the skull located behind the nose.

- Mitral cells send their axons to a number of brain areas, including the anterior olfactory nucleus, piriform cortex, the medial amygdala, the entorhinal cortex, and the olfactory tubercle. The piriform cortex is probably the area most closely associated with identifying the odor.he olfactory nerve, similar to the optic nerve, is not part of the peripheral nervous system but is defined as a part of the brain.

Sensory neuron The sensory neurons involved in smell are called olfactory receptor neurons. These receptor neurons contain receptors, called olfactory receptors, that are activated by the odor molecules in the air. The perception of these odor molecules is called a scent.

The 12 Cranial Nerves of the Human Body slide 3 of 4. Functions Each of the 12 cranial nerves has a specific function that helps the brain control the actions of the body. The olfactory nerve is involved in the sense of smell. This nerve has access to the cerebral cortex, but does not pass through the thalamus like other cranial nerves. The optic nerve is involved in the sense of sight. Responsible for vision, damage to this nerve can result in temporary or permanent blindness.

Introduction to Sociology/Print version Your olfactory system, which provides your sense of smell, consists of receptors in the mucous lining of your nose that send information through nerves into your brain. You can lose your sense of smell if any part of the olfactory pathway is damaged or destroyed. This can happen as a result of: 1  Aging. 2  Alzheimer's disease.

Smell is a vulnerable sense and olfactory dysfunctions are common. Few people appreciate the range of information provided by the sense of smell, or think about what life would be like if that information was lost â until it happens to them. The anatomic location of the olfactory nerve, which carries smell information from the receptors inside the nose to the brain, makes it highly susceptible to physical damage. Olfactory nerve fibers pass through a honeycomb-like bone structure known as the cribriform plate as they travel from the nose to the brain.

Sensory Systems/Olfactory System The 350 different receptors are characteristic for only one odorant type. The bond with one odorant molecule starts a molecular chain reaction, which transforms the chemical perception into an electrical signal. The electrical signal proceeds through the olfactory nerve’s axons to the olfactory bulbs.

THE SENSES - A PRIMER TASTE & SMELL. Smell is the most primitive of the senses. Its role in finding food and warning of danger is vital for survival. The receptors of the chemical sensory systems send electrical signals to the brain when they bind to airborne (for smell) and dissolved (taste) molecules. The organization of the olfactory system is somewhat primitive too: receptors are dendrites of neurons that go directly to the brain.

Nervous System Each of the 12 cranial nerves has a specific function within the nervous system. 1  The olfactory nerve (I) carries scent information to the brain from the olfactory epithelium in the roof of the nasal cavity.  The optic nerve (II) carries visual information from the eyes to the brain.
