Olfaction is essential for survival in most vertebrates; however, the degree to which an animal depends on smell is highly varied.The sense of smell, or olfaction, is the special sense through which smells (or odors) are perceived. The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste.. In humans, it occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system.The taste and aroma of food are sensed through special receptors (proteins) on the surface of taste and olfactory cells in our mouth and nose. They provide a direct link between our brain and the outside world. While the number of taste receptors is limited, it is estimated there are about 400 different types of receptors for smell.Expert Answer.

Correctly label the components of the lungs. Correctly label the components of the pulmonary alveoli. Place the respiratory structures into the order that air would pass through them during a normal inspiration. outside of body. 1. trachea. 2. primary bronchus. 3. secondary bronchus.

Step 2. The chemicals bind to G-protein receptors on the cilia, causing a cascade of events to open ion gates to open. This makes the cell depolarize. Step 3. If the stimulus is strong enough, an AP will fire in the sensory neurons (sensory neurons are located in the olfactory epithelium). The sensory neuron will synapse onto the olfactory bulb.

This makes the olfactory system the only sensory system that does not have to first pass signals through the thalamus before cortical processing. This pathway may play roles in discriminating odors, and the emotional, motivational, and memory-related aspects of smell. Figure 35.9. Projection of olfactory information.Chapter 16 assig.

The olfactory nerve is the shortest nerve in the human head. It originates in the olfactory mucosa (mucous membrane) along the roof of your nasal cavity (nostril). This nerve is made of many small nerve fibers called fascicles that are bound together by thin strips of connective tissue.

These 350 receptors are each characteristic of a distinct type of odor. When air enters the nasal passage, a small part of it goes to the olfactory area [24]. The receptors then carry odorants present in the air to specific neurons to be carried to the olfactory bulb in the forebrain [41], where they are identified as different smells [29].An olfactory receptor, which is a dendrite of a specialized neuron, responds when it binds certain molecules inhaled from the environment by sending impulses directly to the olfactory bulb of the brain. Humans have about 12 million olfactory receptors, distributed among hundreds of different receptor types that respond to different odors.You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
