Bone Marrow Real Pictures, Images and Photos

There are two main types of bone marrow: Red marrow and Yellow marrow. The composition and functions of these types differ, and they are found in different locations within the body.

1. Red Bone Marrow: It is also known as myeloid tissue and it is the active haematopoietic tissue responsible for blood cell production (red blood cells, white blood cells, and platelets).
   1. It is most commonly present in flat bones like the sternum (breastbone), pelvis, ribs, skull, and vertebrae. It is also found towards the end of long bones like the femur and humerus.
   2. Red marrow is plentiful in young people but becomes less so as they get older.
   3. Red marrow is composed of various cell types, blood vessels, and a supportive matrix. 
2. Yellow Bone Marrow: Yellow marrow, also known as fatty marrow, is primarily composed of adipocytes or fat cells.
   It contains fewer hematopoietic stem cells and precursor cells compared to red marrow.
   1. It is found mainly in the long bones, such as the femur (thigh bone) and humerus (upper arm bone). 
   2. Yellow marrow is more prevalent in adults than in children.
   3. In severe blood loss or injury conditions, yellow bone marrow can convert back to the red bone marrow to replenish blood cells.

A red bone marrow picture might show dark, spongy tissue with lots of blood vessels, while a picture of yellow bone marrow might show a fatty, yellowish substance. 

By visualising the bone marrow images, we can better understand the accurate structure and function of each type of bone marrow.

The structure of bone marrow is intricate and consists of various components that support its functions. Here is a detailed overview of the bone marrow structure:

1. Trabecular Bone: Sometimes referred to as cancellous or spongy bone, has voids that home the bone marrow. 
   1. An open lattice-like structure is formed by the network of bony struts that make up trabecular bone. 
   2. The bone marrow is supported and kept structurally sound by these trabeculae.
2. Bone Marrow Cavity: Within the trabecular bone, bone marrow cavities are present. Bone marrow is housed in these cavities, which are confined chambers. 
   1. Adult long bones like the femur (thigh bone) and humerus (upper arm bone), as well as flat bones like the sternum (breastbone), pelvis, ribs, skull, and vertebrae, are where the bone marrow cavities are most frequently found.
3. Red Marrow: The core portion of the bone marrow cavities is occupied by the red marrow.
   
   It has a lot of blood vessels and produces blood cells through a process called hematopoiesis. Red marrow consists of the following components:
   1. Hematopoietic Stem Cells: These undifferentiated cells have the capacity to generate several blood cell subtypes.
      1. Lymphoid Cells: These cells develop into immune cells. This includes T cells, B cells, and natural killer cells.
      2. Megakaryocytes: These cells produce platelets, which help with blood clotting.
      3. Erythroblasts: These cells produce red blood cells, which carry oxygen throughout the body.
   2. Precursor Cells: Hematopoietic stem cells give rise to precursor cells, also referred to as progenitor cells.
      
      They proceed through differentiation and maturation to make platelets, white blood cells, and red blood cells.
   3. Adipocytes: A limited number of fat cells, or adipocytes, are present in red marrow. They are not as prevalent as yellow marrow, though.
   4. Reticular Cells: The bone marrow's structural integrity is supported by a network of reticular fibers that are produced by reticular cells.
4. Yellow Marrow: Yellow marrow is found in the peripheral region of the bone marrow cavities, surrounding the red marrow. 
   1. Adipose tissue, which is made up of fat cells called adipocytes, makes up the majority of it. 
   2. Triglycerides are stored in yellow marrow, which gives the body access to reserves of energy.
5. Blood Vessels: The bone marrow has a dense network of blood arteries running through it, making it highly vascularized. 
   1. The oxygen, nutrients, and hormones that are needed by the bone marrow are delivered through blood vessels such as arteries, veins, and capillaries. 
   2. Additionally, they eliminate waste items produced during hematopoiesis.
6. Reticular Network: Reticulated cells that create reticular fibers are found in the bone marrow.
   
   These fibers create a network of support throughout the marrow, giving the numerous cells and components structural support and anchoring.
7. Endosteum: The inner surface of the bone marrow cavity is lined with a thin layer of connective tissue called the endosteum.
   
   It contains cells that contribute to bone remodeling and controls the actions of bone-forming cells.

The bone marrow is responsible for essential functions that are vital for the proper functioning of the body. This section talks about these vital functions of bone marrow. 

1. Hematopoiesis: It is the process of producing distinct blood cell types. It is carried out by the bone marrow.
   
   It creates platelets (thrombocytes), which help blood clot, leukocytes, which fight infections, and red blood cells (erythrocytes), which deliver oxygen.
2. Oxygenation and Carbon Dioxide Removal: Haemoglobin, a component of red blood cells made in the bone marrow, binds to oxygen in the lungs and carries it to tissues all over the body.
   
   The waste product carbon dioxide is simultaneously removed and sent back to the lungs for expiration.
3. Immune Function: Different types of white blood cells, such as lymphocytes, monocytes, neutrophils, eosinophils, and basophils, are produced by the bone marrow.
   
   Through their defense against infections, viruses, bacteria, and other hazardous agents, these cells serve crucial roles in the immune system.
4. Blood Clotting: Blood clotting depends on the bone marrow-derived platelets. In order to create a clot and stop excessive bleeding, platelets gather and attach to the site of a blood vessel injury.
5. Stem Cell Maintenance: Haematopoietic stem cells, which may divide and develop into numerous types of blood cells, are found in the bone marrow.
   
   Throughout life, these stem cells aid in maintaining a steady flow of fresh blood cells.

There is no denying that any disturbances in the normal functioning of bone marrow can impose many serious problems on a person's health.
