You Are Starving You Decide To Order Delicious Garlic Shrimp From Ch
You are starving!! You decide to order delicious garlic shrimp from Chinese #1 down the street. You can't wait for it to arrive. Finally, you hear the doorbell, and already you can smell the wonderful garlic shrimp and rice waiting for you in the bag. You open your containers, and pile a heap of white rice, and then pour the garlic shrimp on top of the rice. You grab one of the shrimp from the top, and whoa, it's hot! You almost burn your fingertips. You take a huge bite, and taste the satisfying garlic shrimp in your mouth. It is delicious. Using the power points and the textbook, students will answer the following questions: 1. Describe HOW you know you are eating and smell garlic shrimp versus rotten apples? What sense is being used? Is it a general sense or a special sense? 2. Describe what type of receptors are used; how is the sensory information transmitted to the brain? Please be as specific as possible. 3. Your final submission should be posted on this discussion forum for other students to view. Students can use this forum to communicate with each other, call each on the phone and/or email.
Paper For Above instruction
When savoring the aroma and taste of garlic shrimp, distinct sensory processes are engaged that enable us to differentiate between food and spoilage. The primary sense involved in identifying the smell of garlic shrimp versus rotten apples is olfaction, which is classified as a specialized (or chemoreceptive) sense. Olfaction relies on specialized sensory receptors located in the olfactory epithelium within the nasal cavity. These receptors detect volatile chemical compounds released from substances such as food, spices, or decaying matter.
The process begins when molecules of garlic vapor or the smell of rotten apples reach the olfactory epithelium. The odor molecules bind to specific olfactory receptors on the cilia of olfactory receptor neurons. These receptors are G protein-coupled receptors (GPCRs), which undergo conformational changes upon binding to their specific ligands. The activation of these receptors triggers intracellular signaling pathways, causing depolarization and generating nerve impulses that are transmitted along the olfactory nerve fibers (cranial nerve I) to the olfactory bulb of the brain (Mori et al., 2006).
The transmission of sensory information involves the conversion of chemical signals into electrical signals in the receptor neurons, which then travel via the olfactory nerve to the olfactory bulb. From there, the information is relayed through the olfactory tract to higher brain centers, including the piriform cortex, amygdala, and entorhinal cortex, where the perception and identification of smell occur (Okajima & Haga, 2010). This neural pathway allows us to recognize various odors, distinguish fresh garlic shrimp from spoiled food, and generate appropriate behavioral responses.
In contrast, the perception of taste involves the gustatory system, which detects chemical stimuli via taste receptor cells on the tongue and in the oral cavity. These cells are located within taste buds and respond to different taste modalities such as sweet, salty, sour, bitter, and umami. When biting into the garlic shrimp, mechanoreceptors and thermoreceptors also contribute to the sensation of temperature and texture, but smell primarily defines the flavor profile (Small & Green, 2012).
Furthermore, tactile sensations like heat from the hot shrimp are processed by mechanoreceptors and thermoreceptors in the skin. These receptors relay their signals through the somatosensory system via the trigeminal nerve (cranial nerve V) to the brain for interpretation of temperature, texture, and pain (Kandel et al., 2013). The combined input from olfactory, gustatory, and somatosensory systems creates the holistic experience of eating, tasting, and smelling the garlic shrimp.
In summary, the identification of garlic shrimp's aroma and flavor involves specialized sensory receptors in the olfactory epithelium for smell and taste buds for flavor, with information transmitted via cranial nerves I and VII, respectively, to the brain. The brain processes these signals to enable recognition and differentiation between fresh, delicious food and unsuitable, rotten matter, ensuring our safety and enjoyment.
