Epilepsy Epilepsy, a neurological disorder characterized by recurrent seizures, has long captivated the curiosity of medical professionals and researchers alike. Despite its prevalence and impact on millions of lives worldwide, epilepsy remains shrouded in misconceptions and stigmas. Let's delve into the intricacies of this condition, exploring its mechanisms, manifestations, and avenues for support and treatment. The Spectrum of Seizures: Epilepsy manifests across a broad spectrum of seizure types, each with its unique characteristics and implications. Seizures can range from focal seizures, which originate in a specific area of the brain, to generalized seizures, which involve widespread neuronal activity. These seizures may present as convulsions, staring spells, unusual sensations, or alterations in consciousness, underscoring the diverse ways in which epilepsy can affect individuals. Unraveling the Neurological Underpinnings: At its core, epilepsy arises from disruptions in th...

Cirrhosis: A Silent Threat to Liver Health Cirrhosis is a condition that affects the liver, often silently progressing until it reaches an advanced stage. This chronic liver disease is characterized by the replacement of healthy liver tissue with scar tissue, which impairs liver function over time. While the liver has a remarkable ability to regenerate, cirrhosis represents irreversible damage, posing significant health risks if left untreated. What Causes Cirrhosis? Chronic alcoholism: Excessive alcohol consumption over time can lead to liver damage and cirrhosis. Hepatitis B and C: Chronic infection with these viruses can cause inflammation and liver damage, eventually leading to cirrhosis. Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH): These conditions, often associated with obesity and metabolic syndrome, can progress to cirrhosis. Autoimmune hepatitis: The body's immune system attacks the liver, leading to inflammation and scarring. Biliary...

Spleen Spleen is bean-shaped organ present below the diaphragm on the left side inside the rib which is 9 and 11. Our left kidney is present below the spleen. The tail of pancreas touches the spleen. Splenic artery, splenic vein and lymphatic vessels enter and leave the spleen through hilum.  Functions of spleen Spleen produces red blood cells in case of anemia and at fetus journey inside mother's womb.  In adults, its main function is blood filtration and adaptive immune response.  There are two types of tissues in spleen which is white pulp and red pulp. Red  pulp is composed of splenic cords and venous sinuses, It filtrates our blood circulation by detecting old and damaged red blood cells. Inside red pulp, unhealthy RBC'S leave blood Vessels and enter a system called 'Open Circulation' where macrophages engulf unhealthy cells. Through Venous Sinuses, healthy red blood cells bend and move very quickly while old ones are fragile and can't so destroyed by macroph...

Liver And Its Parts Liver Liver is the main and most active organ of human body which is situated on the right side at the top of stomach below the diaphragm. It is dark-reddish brown organ which weighs around 3 pounds. Liver can regenerate itself in humans. Parts of Liver  It contains 4 lobes. We can see first two lobes but remaining two lobes cannot be seen from front side. Each lobe contains 8 segments, and each segment contains 1000 of lobules. Lobules contain hepatocytes which are endothelial cells performing numerous functions inside liver. Right lobe of liver is larger then left lobe. Gallbladder is present just below the right lobe of liver which stores bile.  Liver contains hepatic artery, hepatic vein and hepatic duct. Hepatic artery carries oxygenated blood from heart while Hepatic vein carries de-oxygenated blood from small intestine, pancreas and spleen. Hepatic duct or bile duct carries bile from gallbladder into GI tract. Hepatocytes are the functional cells of ...

BRAIN AND ITS FUNCTIONS Brain  Brain is the main organ of our body and controls Voluntary as well as Involuntary functions. Whatever we think, feel and performed all due to our brain working. You know shape of our brain is like Walnut which is dry fruit and boosts our brain function. If any part of our brain will destroy, then body will affect from it. Cerebrum Cerebrum is wrinkled part of brain which shows intelligence of person, if person has more wrinkled cerebrum it means he has more surface area. More the surface area, more the person will be intelligent.  Cerebrum is divided into two parts which are right and left cerebral Hemispheres. Left side for  recognition of  words and right for recognition of colors, if both works consecutively confliction occurs. Right and Left Cerebrum are connected with nerve fiber known as Corpus Callosum. Lobes of Brain Brain is divided into four lobes which are part of cerebrum. Frontal Parietal Temporal Occipital Frontal Lobe ,...
