Components Of The Olfactory System

Of the five senses that humans employ in everyday life, taste and sight are two of the more interesting senses. They are continually developed throughout our entire lives and we are exposed to new sights and tastes everyday. Many people think that our senses are all unique and independent of each other, but taste and sight are surprising similar in many aspects, such as their development. Not only are taste and sight developed similarly, but they are also affected by familiarity, socialization, and memory. Although many people in the world believe that all our senses are different in function and development, taste and sight have a unique connection between the two senses that makes them very similar.

Smell, on the other hand, is the sense that comes from odor molecules attaching to the olfactory nerve. Air carries the odor into the nose. Then odor contacts the olfactory nerves at the top of the nasal passages. The the olfactory nerves send a signal to the olfactory bulb of the brain, and the nerve sends a signal to the front of the brain. The forebrain translates the signals of the odor into a specific smell (Swindle, Mark).

I decided to research Anosmia to do my chapter 3 activity over. Anosmia is a condition that affects olfaction and the olfactory system. The olfactory system is our sense of smell, and consists of the olfactory epithelium; olfactory receptor cells; olfactory bulbs; Amygdala; The olfactory cortex, the limbic system; the thalamus; and the orbitofrontal cortex. Odors travel through the nasal passages and reach the olfactory epithelium. The olfactory epithelium has around 10 million olfactory receptor cells that detect the odor that travels up the nasal cavity. The olfactory bulb receives the information from the cells and sends them to the Amygdala and the olfactory cortex. The information is then sent to the limbic system from the olfactory cortex. After the information is sent to the limbic system it is sent to the thalamus and onto the orbitofrontal cortex, where the information is processed.

Though our sensory organs may be working fine, environmental influences may distort our interpretation of the data the organ is sending to us. For example, we could look down a street and not see anyone and think it is safe to walk down that street, but someone could be behind a tree or other object. We do not always interpret sensory data correctly no matter what sensory organ we are using. That is the most important reason we should be aware that we may not always rely on sensory information. Our senses are who we are, without them we are left to isolation and our ability to think and learn due to lack of experience. Senses are our connection from the physical world into the realm of our mind. “There is nothing in the mind unless it is first in the senses” (Kirby &

Humans have five means of sensing information, which are hearing, tasting, smelling, touching, and seeing (Breedlove & Watson, 2013). All incoming information is sensed in a similar way for each of the five modalities. The sensory receptor organs filter the information that we come into contact with by deciding which information to pay attention to and which information to ignore. The event that activates the sensory organ is referred to as a stimulus; hence, feeling a finger on your arm, hearing music, or seeing an object are all referred to as stimuli. Additionally, we have receptor cells within or sensory organs, the receptor cells perceive specific types of simulation and convert the sensed stimuli

In 2010, Darek Fidyka had stabbed eighteen times in the back, with three of the stabs puncturing his lung, by his former friend, Jaroslaw, during a drunken rage. Jaroslaw had felt that Darek had started a relationship with his wife while they were still married. His injury resulted in him being paralyzed from the chest down.

Our brain is completely isolated from the rest of the world. The only way one is able to use his or her brain is to use the body’s senses as a way to send messages to it. Humans have five recognized senses that are responsible for giving our brain vital information. These senses are one’s taste, touch, smell, hearing, and vision. While these senses are highly important to our daily functions, the Senses Challenge has shown me how unaware we are of how complex they really are.

As a human being, there are few experiences that can be objectively more gratifying than those of taste and smell. From heavenly aromas wafting through a kitchen to the first sip of an effervescent soda, these sensations and stimulations allow humans to connect with their environment in an ineffably beautiful and practical way. However, the capableness to taste and smell are often overlooked by those who assume that all have an identical ability to do so. In fact, more than 15 percent of adults are believed to have a smell or taste disorder in the United States alone (“Taste Disorders”, 2014). Contrary to popular belief, an inability to taste or smell can be quite dangerous, removing an early warning system that might allow an individual to

Odors are a distinctive smell, especially an un unpleasant one. Odors attach to receptors of olfactory cells in the nasal mucosa. Olfactory cells in the nasal mucosa are where they activate nerve signals. These signals are processed in the olfactory bulb, a structure at the base of the forebrain that transmit the signal to other brain areas. People have about 450 olfactory receptors. Each receptor can be activated by many different odor molecules, and each odor molecule can activate several different types of receptors. However, the forces that bind receptors and odor molecules can greatly differ in strength, so that some interactions are better “fits” than others. The complication of receptors and their synergy with odor molecules are what

The limbic system, which deals with emotional memory, links smell to memory. The connection can often happen spontaneously, with a smell acting as a trigger in recalling a long-forgotten experience. The perfume industry thrives on the limbic

You have possibly known since elementary school that we have five senses: smell (olfaction), hearing (audition), vision ,taste (gustation), and touch (somatosensation). It turns out that this concept of five senses is overgeneralized. We also have a sensory system that gives information about balance (the vestibular sense), body situation and movement (proprioception and kinesthesia), pain (nociception), and temperature (thermoception).

Anosmia (an-OHZ-me-uh) is the inability to perceive odor or the lack of functioning olfactory nerves, also known as the loss of the sense of smell. People do not consider this as a disability considering the fact that when you have a sinus infection you may lose your ability to smell. However, there are a few people who suffer from congenital

You and my husband both agree on the sense of smell to loose, he stated every thing else is important to him the sense of touch, hearing, sight. I stated that your sense of smell is important for tasting food and wanting to eat I explained you might not want to eat with that type of loss. He said he would still eat any way because you have to eat.

T F 1. Generally when one loses his/her sense of smell, he/she also loses the sense
