Abnormal sensations such as prickling, tingling, itching, burning or cold, skin crawling or impaired sensationsâare all called parasthesia. These symptoms usually arise from nerve damage (neuropathy). Continued nerve damage can lead to numbness (lost of sensation) or paralysis (loss of movement and sensation). Paresthesia is one of the symptoms of Hypervitaminosis-D.
Hemoglobin and hemoglobin-like molecules are also found in many invertebrates, fungi, and plants. In these organisms, hemoglobins may carry oxygen, or they may act to transport and regulate other things such as carbon dioxide, nitric oxide, hydrogen sulfide and sulfide.emoglobin deficiency can be caused either by a decreased amount of hemoglobin molecules, as in anemia, or by decreased ability of each molecule to bind oxygen at the same partial pressure of oxygen.
Hemoglobin is present in red blood cells and is an essential chemical which carries oxygen from lungs to other parts of the body. It is metalloprotein having quarternary structure which contains iron and performs the important function of transporting oxygen via RBCs in blood in mammals as well as other animals.he name hemoglobin is made from the blend of heme and globin. Globin is the globular protein in which heme-an iron atom is embedded which is the main chemical binding oxygen. The common type of hemoglobin consists of four subunits:
