Transplantation Potential: Bone marrow transplantation, also known as hematopoietic stem cell transplantation, is a life-saving procedure for individuals with certain cancers, genetic disorders, or bone marrow failure. It involves replacing damaged or diseased bone marrow with healthy stem cells to restore blood cell production.
When it form lining the cavity of heart, blood vessels and lymph vessels, it is called endothelium. Coelomic cavity is lined with coelomic epithelium or mesothelium, when it form covering around visceral organs it is called peritoneum and while lining bone marrow it is called endosteum. The squamous epithelium is of two kinds:
Statement I : Bone marrow is the main lymphoid organ where all blood cells including lymphocytes are produced. Statement II : Both bone marrow and thymus provide micro environments for the development and maturation of T-lymphocytes. In the light of above statements, choose the most appropriate answer from the options given below (NEET 2024)
A site for red blood cell production in the bone marrow. Storage for minerals like calcium and phosphorus. The framework for movement, allowing for a wide range of motion when muscles attached to the bones contract. b. The vertebral column, or backbone, is composed of 33 bones called vertebrae.
The skeletal system is not just a rigid structure; it serves as a framework for the body, providing support and protection to internal organs such as the heart, lungs, and brain. Additionally, bones play a vital role in the production of red blood cells, white blood cells, and platelets in the bone marrow.
4. The hip bone protects organs like the kidneys and the bladder. 5. The eyeballs are protected by the bony eye sockets. It helps to move our body with the help of the muscles. Red blood cells and white blood cells are produced in the bone marrow. Bones also store minerals like calcium and phosphorus.
Ball and socket joint allows the maximum movement in all the directions. Hinge joint provides back and forth movement in one plane similar to door hinges. Pivot joint allows one bone to rotate over the other. The only movable bone in skull is the lower jaw bone. Birds have hollow bones that make them light weight and help to fly.
Ans. The main functions of the skeletal system include providing structure and support to the body, protecting vital organs, facilitating movement by serving as attachment points for muscles, producing blood cells in the bone marrow, and storing essential minerals such as calcium and phosphorus.
A bone marrow transplant (also known as a stem cell transplant) can potentially cure SCD. Additional treatments focus on alleviating symptoms, reducing complications, and extending the patient's lifespan. Gene therapy is also being explored as a promising treatment option. The UK recently became the first country to approve gene therapy for SCD.
Leukemia: A group of cancers starting in the bone marrow, resulting in high numbers of abnormal white blood cells. Sarcoma: Cancer of connective tissue. Oncology: The study of cancer.
