Scientists discover new organ in the throat | thecbsesolver | New organ 2020 | interstitium

By


Scientists have discovered a new organ: a set of salivary glands set deep in the upper part of the throat. 

 


This nasopharynx region — behind the nose, was not thought to host anything but microscopic, diffuse, salivary glands; but the newly discovered set are about 1.5 inches (3.9 centimetres) in length on average. Till now it is known that there are only three main Salivary Glands in human body but, this new organ “interstitium” claimed to be. The country where it’s found that is Netherlands and the institute is Netherlands Cancer Institute.

 

Parotid Gland: 

It is the largest  gland of our body and secretes nearly 20 - 30 % of saliva in the body. It is present near last molars that is ears and it is also a exocrine gland which secrets it secretion through ducts to the last second molars.

 

Submandibular Gland:

It is the second largest gland of our body and secretes nearly 65 - 70 % of saliva in the body. It is present below the tongue that is ears and it is also a exocrine gland which secrets it secretion through ducts.


Sublingual Gland:

It is the smallest gland of our body and secretes nearly 5 - 10 % of saliva in the body. It is present near the tongue and it is a exocrine gland.

 


Discovery: “Interstitium”

This kind of discovery  in human body is made after 30 years. The discovery was accidental. Researchers at the Netherlands Cancer Institute were using a combination of CT scans and positron emission tomography (PET) scans called PSMA PET-CT to study prostate cancer. In PSMA PET-CT scanning, doctors inject a radioactive "tracer" into the patient. This tracer binds well to the protein PSMA, which is elevated in prostate cancer cells. Clinical trials have found that PSMA PET-CT scanning is better than conventional imaging at detecting metastasized prostate cancer.

Soap vs Hand Sanitizer | Which is better: Soap or hand sanitizer? | TCS - TheCBSESolver

By
  Which is better: Soap or hand sanitizer? Soap vs Hand Sanitizer.  Your hands are anything but smooth. With peaks and valleys, folds and rifts, there are plenty of hiding places for a virus to stick. If you then touch your face, the virus can infect you. But there are two extraordinarily simple ways you can keep that from happening: soap and water, and hand sanitizer. So which is better? The corona virus that causes COVID-19 is one of many viruses whose protective outer surface is made of a lipid bi-layer. These lipids are pin shaped molecules whose heads are attracted to water, and tails are repulsed by it. So in water-rich environments, lipids naturally form a shell like this, with the heads outside and the tails inside. Their shared reaction to water makes the lipids stick loosely together— this is called the hydrophobic effect. This outer structure helps the molecular machinery of the virus break through cellular membranes and hijacks our cells. But it has thou...

Earthquake | Why earthquake happens | Why are earthquakes so hard to predict? | TCS - The CBSE Solver

By
  Early Story:- In 132 CE, Chinese polymath Zhang Heng presented the Han court with his latest invention. This large vase, he claimed, could tell them whenever an earthquake occurred in their kingdom– including the direction they should send aid. The court was somewhat skeptical, especially when the device triggered on a seemingly quiet afternoon. But when messengers came for help days later, their doubts turned to gratitude. Today, we no longer rely on pots to identify seismic events, but earthquakes still offer a unique challenge to those trying to track them. So why are earthquakes so hard to anticipate, and how could we get better at predicting them?   Earth’s structure: To answer that, we need to understand some theories behind how earthquakes occur. Earth’s crust is made from several vast, jagged slabs of rock called tectonic plates , each riding on a hot, partially molten layer of Earth’s mantle . This causes the plates to spread very slowly, at anywhere from ...
