Chronic Stress Is DESTROYING Your Body: Part 2 💔🫀 Heart Disease 💔 2025 data: Stress-related heart issues spiking post-pandemic! Over half of U.S. workers report job anxiety → higher cardiovascular risks. Chronic stress → plaque buildup in coronary arteries (cortisol/adrenaline inflame artery walls → LDL cholesterol slips in → plaques form → heart attack risk!) Digestive System 🤢 Butterflies when anxious? Stress diverts blood from gut → slows digestion → acid reflux, IBS, constipation Cortisol inflames gut lining (tunica mucosa) → ulcer risk, poor nutrient absorption Weight gain from cortisol-driven sugar cravings + elevated blood glucose! Musculoskeletal System 💪 Over time: ↑ obesity, diabetes, mental health decline Part 3: How to fight back!

How Ibuprofen Actually Works Inside Your Body 💊🫀 Ever wonder what happens after you swallow that ibuprofen? What Is Ibuprofen? 🔬 NSAID (non-steroidal anti-inflammatory drug) - brand names: Advil, Motrin Uses: ✅ Analgesic (pain reliever) ✅ Antipyretic (fever reducer) ✅ Anti-inflammatory The Journey 🗺️ 1️⃣ Stomach – Tablet mixes with gastric juices (stomach acid, enzymes, mucus) → starts dissolving → releases active ingredients. Small amount absorbed through stomach lining (seen here!) 2️⃣ Small Intestine – Where the MAJORITY gets absorbed! Tons of blood vessels to absorb nutrients (or in this case, medication) 3️⃣ Bloodstream – Now it circulates throughout your entire body! Timeline: 30-60 minutes for absorption to start taking effect! ⏱️ But how does ibuprofen ACTUALLY work once it's in your bloodstream?

Heart Valve Problems: Leaky vs. Stiff 🫀⚠️ Ever heard of someone having a "leaky valve" or a valve that's "too stiff"? Let's break down what that actually means! What Valves Do ✅ Check out this pulmonary trunk with one of the heart's 4 valves—see those semi-lunar flaps of tissue? Valves allow blood to travel in ONE direction only—we don't want backflow! In this case: Blood leaves right ventricle → pulmonary trunk. Those flaps catch any blood trying to leak back in! The 2 Main Valve Problems 🚨 1. Regurgitation (Leaky Valve) 💧 The valve leaks—blood flows back in the wrong direction! Examples: Aortic regurgitation, mitral regurgitation Problem: Heart has to pump blood it already pumped → constant congestion/buildup downstream → heart works HARDER! 2. Stenosis (Stiff/Narrow Valve) 🚧 The valve won't open enough—it's too narrow or stiff! Examples: Aortic stenosis, mitral stenosis Problem: Heart has to contract MORE forcefully to pump blood through the narrow opening → heart works HARDER! The Takeaway 💡 Either condition forces your heart to work overtime! Whether it's pumping the same blood twice (regurgitation) or forcing blood through a tight opening (stenosis), the heart pays the price. 💔 Follow for More Anatomical Awesomeness! 🧠✨ #heartvalve #regurgitation #stenosis #aorticvalve #mitralvalve #cardiology #heartdisease #pulmonarytrunk #cardiovascular #humananatomy #cadaverlab #anatomyeducation #medstudent #premed

Hernias Explained: Part 3 - Treatment & Prevention! 🏥 Femoral Hernia: Contents push through femoral canal (more common in females but only 3-5% of all hernias). Inguinal hernias = 75% of all hernias! Treatment Options 🩺 Asymptomatic hernias (no pain, reducible) → sometimes no treatment needed, just monitoring Painful hernias → concern for incarceration (stuck, can't push back) → leads to strangulation (blood cut off) → MEDICAL EMERGENCY! Needs immediate surgery + mesh repair. Prevention 🛡️ ✅ Maintain healthy weight (less visceral fat = less abdominal pressure) ✅ Eat fiber + drink water (prevent straining!) ✅ Core exercises (strengthen abdominal wall) The Takeaway: Reduce pressure, strengthen your core, stay healthy! 💪 Follow for More Anatomical Awesomeness! 🧠✨ #hernias #femoralhernia #incarceratedhernia #prevention #coreexercises #humananatomy #anatomyeducation

Not All Fat Is Created Equal: The Dangerous Kind ⚠️🫀 Let's break down fat types—because location matters! White Fat (Adipose Tissue) 🔬 What you see on this cadaver is white fat (looks yellow from embalming—normally white/light yellow in living people). Stores energy, provides padding & insulation, builds up under skin OR around organs. The 2 Types 📍 1. Subcutaneous Fat – Under skin, on top of muscles. Hides your abs! Ranges from millimeters to inches thick. 2. Visceral Fat – Wraps around organs (heart, liver, intestines) Check the difference: This body has healthy levels vs. this body with excessive visceral fat. Why Visceral Fat = "The Dangerous Fat" 🚨 Excess visceral fat strongly linked to: 💔 Type 2 diabetes 💔 Heart disease 💔 High blood pressure 💔 Inflammation 💔 Reduced insulin sensitivity The Takeaway: WHERE your fat is located matters as much as how much you have! 🧠 Watch the full breakdown—link in bio! 🎥 #subcutaneousfat #visceralfat #bodyfat #health #diabetes #heartdisease #humananatomy #cadaverlab #anatomyeducation

Hernias Explained: Part 2 - Why Males Get Groin Hernias More! 🏋️‍♂️ Ventral Subtypes: Umbilical (at belly button) or Epigastric (elsewhere on linea alba) Why Males Get Groin Hernias More 🤔 Testes descent story: Testes start by kidneys, descend down, then herniate through the inguinal canal to outside the body! What they bring: Veins, arteries, nerves Vas deferens Muscle All form the spermatic cord → testes push into skin → create scrotum! The Result: This natural herniation makes the inguinal canal LARGER in males → much more likely to develop inguinal (groin) hernias! Inguinal hernia = fat/intestine pushes through inguinal canal Check out this cadaver—see that bulge? That's an inguinal hernia we found during dissection! 🔬 Part 3: Treatment & prevention!

Your Ankle Has Its Own "Carpal Tunnel Syndrome"! 🦶⚡ Looking at the inside (medial aspect) of the left ankle—see those tendons running behind your "ankle nubby"? That nubby = medial malleolus! 🦴 You've Heard of Carpal Tunnel... 👋 But there's also TARSAL TUNNEL SYNDROME! 🦶 The tarsal tunnel runs right behind the medial malleolus. Normally, retinacular tissue (connective tissue) holds and binds the tendons down. The Problem ⚠️ If there's inflammation, that retinacular tissue doesn't allow for expansion → the tibial nerve gets compressed! What Happens? 😖 Pinching the nerve there sends: Tingling sensations to bottom of foot Potential weakness in intrinsic foot muscles Follow for More Anatomical Awesomeness! ✨ #tarsaltunnel #tarsaltunnelsyndrome #tibialnerve #sciatica #anklepain #medialmalleolus #footpain #nervepain #sciaticnerve #humananatomy #cadaverlab #anatomyeducation #medstudent #premed #physiotherapy

Hernias Explained: Part 1 - You DON'T Want a Bulge Here! 😬 Over 1 million hernia repairs yearly in the US! Risk: 👨 Males: 27% lifetime risk (groin hernias) 👩 Females: 3% (different hernia types) What IS a Hernia? Organ/tissue protruding through abdominal wall (could be fat or intestine pushing through!) The 2 Types: 1️⃣ Ventral hernia (affects females more) 2️⃣ Groin hernia (affects males more) The Key Player: Linea Alba 📍 Vertical "white line" dividing the rectus abdominis (six-pack muscle). The Problem: Pregnancy or obesity can stretch the linea alba (diastasis recti) → weakness in abdominal wall → higher hernia risk! See this cadaver? Linea alba is wider than normal!

Not All Fat Is Created Equal: Subcutaneous vs. Visceral Fat 🫀📏 Let's review key facts about fat—because understanding the difference could save your life! White Adipose Tissue (White Fat) 🔬 What you're seeing on this cadaver is white fat (looks yellow due to embalming—in living people it's white to light yellow). Functions: ✅ Stores energy ✅ Provides padding & insulation ✅ Builds up under skin OR around organs The 2 Locations Matter! 📍 1. Subcutaneous Fat – Just under skin, on top of muscles This hides your abs and muscles if thick enough! Can range from millimeters (like this leg) to many centimeters/inches(like this abdomen)! 2. Visceral Fat – Deeper inside, wrapping around organs (heart, liver, intestines) Check the difference: This body has thinner visceral fat (healthier level) vs. this body with much more visceral fat (unhealthy amount). Why "Healthy" vs "Unhealthy"? ⚠️ Visceral fat = "the more dangerous fat" Excess visceral fat is strongly linked to: 💔 Type 2 diabetes 💔 Heart disease 💔 High blood pressure 💔 Increased inflammation 💔 Reduced insulin sensitivity The Takeaway: Where your fat is located matters as much (or more!) than how much you have! 🧠 Want the full breakdown?

C-Sections Explained: Part 3 - Inside the Abdominal Cavity 👶✂️ Let's finally see what happens after cutting through the linea alba! Inside the Abdominal Cavity 🔬 After separating the rectus abdominis muscle heads, surgeons encounter the peritoneum (thin serous membrane)—they go through this too! What's Inside? 🫃 ✅ Greater omentum – Fatty apron-like tissue draping over intestines (but in full-term pregnancy, it's pushed out of the way!) ✅ Small intestine – Also pushed aside/behind the uterus during pregnancy ✅ Uterus – There it is! (This one is small since she was in her 90s—imagine it full-term size!) ✅ Ovary – Connected to the uterine tube! The C-Section Cut ✂️ After cutting through the peritoneum, the uterus is right there jutting out! Surgeons make a transverse incision in the rough position of the infant's head → birth the infant + placenta (have to remove placenta, amniotic fluid, everything!) Closing Up 🧵 Some techniques pull the uterus out to stitch it, then rotate it back into the cavity. The uterus is smaller now (no baby inside!) but still pretty big.

C-Sections Explained: Part 2 - Getting to the Uterus Without Cutting Muscle! 💪✂️ After cutting through the hypodermis (fat layer), surgeons stop using the scalpel and switch to blunt dissection (using hands and blunt instruments). Why? 🤔 Cutting through muscle = longer recovery + more complications! Blunt dissection carefully reveals deeper tissues without severing blood vessels. The Anatomy Revealed 🔬 Rectus abdominis (your "six-pack"—actually 8 blocks for most people! 😅) Rectus sheath – White connective tissue covering the muscle (seen on left side of this dissection) What forms the rectus sheath? Fusion of aponeuroses (sheet-like tendons) from 3 lateral muscles: External oblique Internal oblique Transversus abdominis The Linea Alba 📍 The rectus sheath from the right + left sides meet in the midline, creating the linea alba (Latin for "white line")—that vertical line on defined abs! The Smart Surgical Move ✂️ Instead of cutting transversely through muscle, surgeons make a vertical cut through the linea alba to expose the abdominal cavity! Why this matters: ✅ Horizontal skin cut = hidden by swimsuit ("bikini cut") ✅ Vertical linea alba cut = spares muscle from excessive damage ✅ Faster recovery, fewer complications! 💯 Part 3: What's inside the abdominal cavity!

C-Sections Explained: Part 1 - The First Incision ✂️👶 20-30% of all births are C-sections—and that number is rising! Since they're so common, let's break down what ACTUALLY happens layer by layer. The Landmarks 📍 Using Jeffrey the Skeleton to show where incisions are made: Most common: 2-5 cm above the pubic symphysis (avoids bladder/pelvic structures) Goes from one ASIS (hip bone prominence) across to the other—stopping a few cm before each side. The First Incision ✂️ Here's what's interesting: The initial cut does NOT go all the way to the uterus! They avoid cutting transversely through the rectus abdominis (six-pack muscle).
