If haemoglobin is not present in body, how much time |

Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body. If your hemoglobin levels are abnormal, it may be a sign that you have a blood disorder. Other names: Hb, Hgb What is it used for? A hemoglobin test is often used to CHECK for anemia, a CONDITION in which your body has fewer red blood cells than normal. If you have anemia, your cells don't get all the oxygen they need. Hemoglobin tests are ALSO frequently performed with other tests, such as: Hematocrit, which measures the percentage of red blood cells in your blood Complete blood count, which measures the number and type of cells in your blood Why do I need a hemoglobin test? Your HEALTH care provider may have ordered the test as part of a routine exam, or if you have: SYMPTOMS of anemia, which include weakness, dizziness, pale skin, and cold hands and feet A family history of thalassemia, sickle cell anemia, or other inherited blood disorder A diet low in iron and minerals A long-term infection Excessive blood loss from an injury or surgical procedure What happens during a hemoglobin test? A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes. |

Which of the following is not a part of CNS |
|
Answer» here The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because it INTEGRATES the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric animals—i.e., all multicellular animals except sponges and radially symmetric animals such as jellyfish—and it contains the majority of the nervous system. The CNS also includes the RETINA[2] and the optic nerve (cranial nerve II),[3][4] as well as the olfactory nerves (cranial nerve I) and olfactory epithelium[5] as parts of the CNS, synapsing directly on brain tissue WITHOUT intermediate ganglia. As such, the olfactory epithelium is the only central nervous tissue in direct CONTACT with the environment, which opens up for therapeutic treatments. [5] The CNS is contained within the dorsal body cavity, with the brain housed in the cranial cavity and the spinal cord in the spinal canal. In vertebrates, the brain is protected by the skull, while the spinal cord is protected by the vertebrae.[6] The brain and spinal cord are both enclosed in the meninges.[6] Within the CNS, the interneuronal space is filled with a large amount of supporting non-nervous cells called neuroglia or glia from the Greek for "glue".[Explanation: |
