Thymus : structure of the thymus gland-role of the thymus gland


 What Is Thymus?

The thymus is located in the chest, behind the breastbone. It is an important part of the lymphatic system and is where T-cells mature. The thymus is especially active during childhood and adolescence but shrinks with age. Scientists believe that the thymus may play a role in aging and in the development of some age-related diseases.

What Is Thymus

Lymphatic system

The structure of the thymus gland

  • The thymus gland is divided into four distinct lobules. The anterior and posterior lobes are separated by the superior and inferior poles, and the medial and lateral lobules are separated by the hilus. Each pole has an indentation, or sinus, which is the point of entry for the blood vessels and nerves. The thymus is surrounded by a thin connective tissue capsule, and it is located in the mediastinum, in front of the heart and behind the sternum.

  • The thymus gland is pretty huge in toddlers and children. It reaches its largest weight of about 1 ounce throughout puberty. After puberty, it starts off evolved to reduce, and in older adults, it’s instead small.

  • The thymus gland is pinkish-gray. It is made from two irregularly shaped components (lobes). The lobes have lots of small bumps called lobules at the floor.

What is the role of the thymus gland?

The thymus gland is an important organ in the immune system. It is located in the chest, behind the breastbone. The thymus gland makes white blood cells called T-cells. These cells fight infection and disease.

The number one function of the thymus gland is to educate special white blood cells referred to as T-lymphocytes or T-cells. White blood cells (lymphocytes) journey out of your bone marrow for your thymus. The lymphocytes mature and grow to be specialized T-cells to your thymus.

After the T-cells have matured, they enter your bloodstream. They journey for your lymph nodes (companies of cells) and other organs for your lymphatic system, in which they assist your immune device fight disease and contamination.

Your thymus gland is likewise a part of your endocrine system. Your endocrine machine makes and releases hormones that manipulate the functions of your body. Your thymus produces and releases numerous hormones consisting of:


  • Thymopoietin: fuels the production of T-cells and tells the pituitary gland to release hormones.

  • Thymosin and thymulin: help make specialized types of T-cells.

  • Thymic humoral thing: keeps your immune system running nicely.

Symptoms of the thymus gland

The thymus gland is a key player in the immune system. It helps to create antibodies and activates the body’s natural defenses. When it doesn’t function properly, it can lead to a number of health problems.       Some common symptoms of a dysfunctional thymus gland include: poor immune system function, allergies, and asthma.

The most common signs of thymus most cancers encompass:

The function of the thymus gland is not well understood. However, there are indications that it may play an important role in the health of the individual. The thymus gland plays a role in the development of the immune system and in the regulation of T-cell activity. It is also known to play a role in the development of T-cell immunity.

The purpose of this paper is to describe the effects that have been observed in the thymus gland due to various lifestyle changes.

These issues include:


  • DiGeorge syndrome: A congenital (present at delivery) ailment in which the thymus is lacking or underdeveloped. Children born with DiGeorge syndrome have extreme immunodeficiency (failure of immune device) and are at a higher danger for infections.

  • Graft-as opposed to-host-ailment: When a thymus gland is transplanted from a stillborn toddler to a toddler born with DiGeorge syndrome, it may help restore the toddler’s immune gadget. However, the transplanted thymus might also create cells that attack the recipient’s cells.

  • Mediastinal hundreds: Masses can encompass tumors, fluid-stuffed sacs (cysts) or other abnormalities to your mediastinal organs, which consist of the thymus. The loads may also or may not be cancerous.

  • Thymoma and thymic carcinoma (thymus cancer): Thymoma and thymic carcinoma are  rare kinds of cancer that could shape in the cells protecting the outdoor floor of your thymus. Thymomas appear like normal thymus cells, grow slowly and don’t commonly unfold beyond your thymus. Thymic carcinoma doesn’t seem like regular thymus cells, grows faster and unfolds greater regularly to different components of your body. Thymoma is easier to treat than thymic carcinoma.

  • Myasthenia gravis: An autoimmune ailment in which your immune gadget forms antibodies that prevent your nerves from passing alerts to your muscle groups, causing muscle weak spots.

  • Pure crimson cellular aplasia: A uncommon autoimmune sickness wherein your body can’t produce new crimson blood cells, leading to extreme anemia.

  • Hypogammaglobulinemia: A ailment wherein your frame produces low tiers of antibodies.

Maintaining the health of the thymus gland

  1. The thymus gland is an important organ in the body that helps to keep the immune system healthy by producing T-cells. The thymus gland starts to decline around the age of eighteen and can disappear completely by the age of thirty-five. Maintaining the health of the thymus gland is important because it can help prevent autoimmune diseases such as Crohn’s disease and multiple sclerosis.

  2. The thymus gland is one of the most important organs in the body. It’s responsible for the development of the immune system. If you want to keep your immune system strong, you need to keep your thymus gland healthy.
