  🫀 Coronary Artery Anatomy Introduction The coronary arteries are vital blood vessels that supply oxygenated blood to the heart muscle (myocardium). Since the heart continuously pumps blood throughout the body, it requires a constant and rich oxygen supply to function effectively. Any obstruction in these arteries can lead to serious cardiac conditions such as angina or myocardial infarction (heart attack). Origin The coronary arteries arise from the ascending aorta , just above the aortic valve , from two openings called the coronary ostia . There are two main coronary arteries: Right Coronary Artery (RCA) Left Coronary Artery (LCA) 1. Right Coronary Artery (RCA) The RCA originates from the right aortic sinus and travels in the right atrioventricular (AV) groove between the right atrium and right ventricle. Major Branches of RCA: Conus branch – supplies the right ventricle outflow tract. Right marginal branch – supplies the right ventricular wall. Posterior descending artery...

Introduction of Pulmonary Embolism Pulmonary Embolism (PE) is a serious and potentially life-threatening condition in which one or more arteries in the lungs become blocked by a blood clot (embolus) . These clots usually originate in the deep veins of the legs — a condition known as Deep Vein Thrombosis (DVT) — and travel through the bloodstream to the lungs. This blockage prevents proper blood flow to lung tissue, reducing oxygen levels in the blood and putting strain on the heart. Common symptoms include: Sudden shortness of breath Sharp chest pain (worsens with deep breathing) Rapid heart rate Cough (sometimes with blood) Risk factors include prolonged immobility (such as during travel or bed rest), surgery, obesity, smoking, pregnancy, certain medications (like oral contraceptives), and clotting disorders. Early diagnosis and treatment with anticoagulant therapy are essential to prevent complications and improve survival outcomes. Causes of Pulmonary disease  🏥 Case Stud...

🌸 Understanding Newborn Baby Reflexes: Nature’s Amazing Instincts When a baby is born, they bring with them a set of fascinating reflexes — natural, automatic movements that show how wonderfully their little bodies are wired to survive and grow. These reflexes are an important part of your baby’s early development and are often checked by doctors soon after birth. 👶 What Are Newborn Reflexes? Newborn reflexes are involuntary movements or actions that occur automatically in response to certain touches, sounds, or positions. These are controlled by the baby’s nervous system and help them adapt to life outside the womb. Each reflex has a purpose — some help with feeding, while others are signs of a healthy brain and nerve function. 🌼 Common Newborn Reflexes 1. Rooting Reflex When you gently touch your baby’s cheek, they turn their head and open their mouth toward the touch. ➡️ Purpose: Helps your baby find the breast or bottle for feeding. 🕒 Disappears around: 4 months. 2. ...

 The Key Role of Thyroid Hormone in Fear Memory Formation Thyroid hormones , primarily triiodothyronine (T3) and thyroxine (T4), are essential regulators of brain development, metabolism, and function. Recent scientific studies have uncovered a surprising and significant role of thyroid hormones in emotional processing, particularly in the formation of fear memories —a critical component of survival but also central to anxiety disorders such as PTSD (Post-Traumatic Stress Disorder). Understanding Fear Memory Fear memory is a form of associative learning where an organism learns to associate a specific stimulus (like a sound or place) with a frightening event (such as a shock). This process is crucial for survival as it helps organisms avoid future threats. Key brain regions involved in fear memory formation include: Amygdala : Processes fear and emotional memories. Hippocampus : Encodes contextual information. Prefrontal cortex : Modulates fear responses and extinction. Thyroid ...

 Gastric Cancer_🧑‍🔬 Gastric cancer, commonly referred to as stomach cancer, is a malignant condition that originates in the lining of the stomach. It is one of the leading causes of cancer-related deaths worldwide, though its incidence has declined in many developed countries due to improvements in food preservation and Helicobacter pylori infection control. Types of Gastric Cancer The most common type of gastric cancer is adenocarcinoma, which arises from the glandular cells of the stomach lining.Less common types include: Lymphoma: Cancer of the immune tissue in the stomach wall Gastrointestinal stromal tumors (GISTs): Arising from the muscle or connective tissue Carcinoid tumors: Originating from hormone-producing cells Causes and Risk Factors Gastric cancer often develops slowly over many years. Risk factors include: Helicobacter pylori infection: A major risk factor Diet: High intake of smoked, salted, or pickled foods Smoking and alcohol: Increase risk Family history: ...

 Prostate Cancer: Early Symptoms and Warning Signs Prostate cancer is one of the most common cancers affecting men, particularly those over the age of 50. It develops in the prostate gland—a small, walnut-shaped gland that produces seminal fluid. Because it usually grows slowly, many men may not experience symptoms in the early stages. However, understanding the starting symptoms can help in early detection and treatment. Understanding the Prostate The prostate is part of the male reproductive system, located just below the bladder and in front of the rectum. It surrounds the urethra, the tube through which urine exits the body. Why Early Detection Matters Prostate cancer often doesn’t show symptoms right away, but as the tumor grows or spreads, it can interfere with normal urinary and sexual functions. Identifying early signs can lead to timely diagnosis and potentially life-saving treatment. Starting Symptoms of Prostate Cancer While many men with early prostate cancer may have n...
