Physiology of Special Chemical Sensation of Taste

MedicoseAcademics

Title: Sense of Taste Presenter: Dr. Faiza, Assistant Professor of Physiology Qualifications: MBBS (Best Graduate, AIMC Lahore) FCPS Physiology ICMT, CHPE, DHPE (STMU) MPH (GC University, Faisalabad) MBA (Virtual University of Pakistan) Learning Objectives: Describe the structure and function of taste buds. Describe the relationship between the taste threshold and taste index of common substances. Explain the chemical basis and signal transduction of taste perception for each type of primary taste sensation. Recognize different abnormalities of taste perception and their causes. Key Topics: Significance of Taste Sensation: Differentiation between pleasant and harmful food Influence on behavior Selection of food based on metabolic needs Receptors of Taste: Taste buds on the tongue Influence of sense of smell, texture of food, and pain stimulation (e.g., by pepper) Primary and Secondary Taste Sensations: Primary taste sensations: Sweet, Sour, Salty, Bitter, Umami Chemical basis and signal transduction mechanisms for each taste Taste Threshold and Index: Taste threshold values for Sweet (sucrose), Salty (NaCl), Sour (HCl), and Bitter (Quinine) Taste index relationship: Inversely proportional to taste threshold Taste Blindness: Inability to taste certain substances, particularly thiourea compounds Example: Phenylthiocarbamide Structure and Function of Taste Buds: Composition: Epithelial cells, Sustentacular/Supporting cells, Taste cells, Basal cells Features: Taste pores, Taste hairs/microvilli, and Taste nerve fibers Location of Taste Buds: Found in papillae of the tongue (Fungiform, Circumvallate, Foliate) Also present on the palate, tonsillar pillars, epiglottis, and proximal esophagus Mechanism of Taste Stimulation: Interaction of taste substances with receptors on microvilli Signal transduction pathways for Umami, Sweet, Bitter, Sour, and Salty tastes Taste Sensitivity and Adaptation: Decrease in sensitivity with age Rapid adaptation of taste sensation Role of Saliva in Taste: Dissolution of tastants to reach receptors Washing away the stimulus Taste Preferences and Aversions: Mechanisms behind taste preference and aversion Influence of receptors and neural pathways Impact of Sensory Nerve Damage: Degeneration of taste buds if the sensory nerve fiber is cut Abnormalities of Taste Detection: Conditions: Ageusia, Hypogeusia, Dysgeusia (parageusia) Causes: Nerve damage, neurological disorders, infections, poor oral hygiene, adverse drug effects, deficiencies, aging, tobacco use, altered neurotransmitter levels Neurotransmitters and Taste Threshold: Effects of serotonin (5-HT) and norepinephrine (NE) on taste sensitivity Supertasters: 25% of the population with heightened sensitivity to taste, especially bitterness Increased number of fungiform papillae

New Drug Discovery and Development .....

NEHA GUPTA

The "New Drug Discovery and Development" process involves the identification, design, testing, and manufacturing of novel pharmaceutical compounds with the aim of introducing new and improved treatments for various medical conditions. This comprehensive endeavor encompasses various stages, including target identification, preclinical studies, clinical trials, regulatory approval, and post-market surveillance. It involves multidisciplinary collaboration among scientists, researchers, clinicians, regulatory experts, and pharmaceutical companies to bring innovative therapies to market and address unmet medical needs.

Title: Sense of Smell Presenter: Dr. Faiza, Assistant Professor of Physiology Qualifications: MBBS (Best Graduate, AIMC Lahore) FCPS Physiology ICMT, CHPE, DHPE (STMU) MPH (GC University, Faisalabad) MBA (Virtual University of Pakistan) Learning Objectives: Describe the primary categories of smells and the concept of odor blindness. Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction. Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain. Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential. Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes. Key Topics: Olfactory Genes: 3% of the human genome accounts for olfactory genes. 400 genes for odorant receptors. Olfactory Membrane: Located in the superior part of the nasal cavity. Medially: Folds downward along the superior septum. Laterally: Folds over the superior turbinate and upper surface of the middle turbinate. Total surface area: 5-10 square centimeters. Olfactory Mucosa: Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell. Sustentacular Cells: Produce mucus and maintain ionic and molecular environment. Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months. Bowman’s Gland: Secretes mucus. Stimulation of Olfactory Cells: Odorant dissolves in mucus and attaches to receptors on olfactory cilia. Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve. Quality of a Good Odorant: Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble. Facilitated by odorant-binding proteins in mucus. Membrane Potential and Action Potential: Resting membrane potential: -55mV. Action potential frequency in the olfactory nerve increases with odorant strength. Adaptation Towards the Sense of Smell: Rapid adaptation within the first second, with further slow adaptation. Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system. Primary Sensations of Smell: Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid. Odor Detection Threshold: Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm). Some toxic substances are odorless at lethal concentrations. Characteristics of Smell: Odor blindness for single substances due to lack of appropriate receptor protein. Behavioral and emotional influences of smell. Transmission of Olfactory Signals: From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition. Primitive, less old, and new olfactory systems with different path

Flu Vaccine Alert in Bangalore Karnataka

addon Scans

As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions. Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says. This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots. To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare. Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself. Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places. Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages. Stay informed, stay safe, and get your flu shot today!
