                                 CANCER CELLS.          Cancer cells  are cells that divide relentlessly, forming solid tumors or flooding the blood with abnormal cells.  Cell division  is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of aging or damage. Healthy cells stop dividing when there is no longer a need for more daughter cells, but cancer cells continue to produce copies. They are also able to spread from one part of the body to another in a process known as  metastasis . There are different categories of cancer cell, defined according to the cell type from which they originate. [2] Carcinoma , the majority of cancer cells are  epithelial  in origin, beginning in the membra...

Recent research has helped to solidify the link between the proper function of the vertebral arteries and vertigo. The researchers specifically focused on a rare condition called loop formation. It is a disorder where small loops form in the vertebral arteries, thereby restricting blood flow. When a cross-section of vertigo patients was studied, this condition seemed to be more common. What else can cause kinks in the vertebral arteries leading to reduced blood flow? Does understanding of the conditions that bring vertigo provide information into a natural way to find relief? Read on to learn more. What Can Reduce Vertebral Blood Flow and Lead to Vertigo? The upper cervical vertebrae play a major role in facilitating blood flow to the brain. Misalignment of the C1 and C2 vertebrae can result in reduced blood flow. Vertigo is not the only possible condition that may result from this scenario. Migraines are also common when these circumstances exist. This explains why it is s...

            Why do we get hiccups (उचक्या /हिचकी) ?      Hiccups are caused by involuntary contractions of your diaphragm — the muscle that separates your chest from your abdomen and plays an important role in breathing. This involuntary contraction causes your vocal cords to close very briefly, which produces the characteristic sound of a hiccup. Hiccups can be annoying but they’re usually short-lived. However, some people may experience recurrent episodes of persistent hiccups. Persistent hiccups, also known as chronic hiccups, are defined as episodes that last longer than 48 hoursTrusted Source. At its most basic, a hiccup is a reflex. It happens when a sudden contraction of your diaphragm causes the muscles of your chest and abdomen to shake. Then, the glottis, or the part of your throat where your vocal cords are located, closes. This creates the noise of air expelled from your lungs, or the “hic” sound that feels involuntary...

                                   BIOLOGY 🧬              Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.Despite the complexity of the science, certain unifying concepts consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis.              Sub-disciplines of biology are defined by the research methods employed and the kind of system studi...
