Where is the location of the thymus gland?
The thymus gland is in the chest, between the lungs and behind the breastbone (sternum). It is just in front of, and above, the heart. The thymus makes white blood cells called T lymphocytes (also called T cells). These are an important part of the body's immune system, which helps us to fight infection.
What is the size of the thymus gland?
At birth it is about 4–6 cm long, 2.5–5 cm wide, and about 1 cm thick. It increases in size until puberty, where it may have a size of about 40–50 g, following which it decreases in size in a process known as involution.
Where is the thyroid is located relative to the thymus?
Other than having similar-sounding names, there is absolutely no connection or similarity between the function of the thyroid and the thymus glands. The thyroid is an endocrine gland that makes thyroid hormone. The thyroid is a butterfly-shaped gland located in the lower front of the neck.
What is thymus and its function?
The thymus is located in the chest behind the breastbone. It plays a key role in immunity by producing immune cells. The organ's primary function is maturing T cells, or T lymphocytes. These are white blood cells responsible for fighting infections. ... The thymus also synthesizes hormones such as insulin and melatonin.
Where is the thymus gland located Mcq?
the thymus gland lies in the upper part of the mediastinum and extends upward till the neck.
Where is the thymus gland located mediastinum?
Location. The thymus gland is a soft bilobed organ which is encapsulated. It lies in the superior mediastinum and in the anterior part of the inferior mediastinum, close to the pericardium. The thymus sits anterior to the great vessels of the heart and deep to the sternum.
What is thymus gland?
The thymus gland is a small organ that lies in the upper chest under the breastbone. It makes white blood cells, called lymphocytes, which protect the body against infections.
Why is the thymus larger in infants?
They found that the more often the infants were breastfed, the higher the interleukin-7 levels in breastmilk, the larger the thymus size and CD3+ lymphocyte output. The partially breastfed infants had larger thymuses than the formula fed infants.
Can you live without a thymus?
The thymus rests on the heart and functions as a "schoolhouse" for immune cells. As cells pass through the thymus they are trained to become T cells, white blood cells that fight infection. A person without a thymus does not produce these T cells and, therefore, is at great risk for developing infections.
What is the location of the thyroid gland?
The thyroid gland lies in the front of your neck in a position just below your Adam's apple. It is made up of two lobes - the right lobe and the left lobe, each about the size of a plum cut in half - and these two lobes are joined by a small bridge of thyroid tissue called the isthmus.
Where is the location of the thyroid gland?
The thyroid is a butterfly-shaped gland that sits low on the front of the neck. Your thyroid lies below your Adam's apple, along the front of the windpipe. The thyroid has two side lobes, connected by a bridge (isthmus) in the middle.
Where is the location of the thyroid?
Your thyroid gland is located at the base of your neck, just below the Adam's apple.
Why is thymus reduced in size?
A new study reveals that thymus atrophy may stem from a decline in its ability to protect against DNA damage from free radicals. ... But starting around the time of puberty, the thymus rapidly decreases in size and loses its capacity to produce enough new T cells.
What causes the thymus gland to enlarge?
The lymphofollicular thymic hyperplasia is associated with autoimmune diseases like myasthenia gravis, Graves disease, or collagen vascular disorders. Patients with these autoimmune disorders can present with varying signs and symptoms depending upon the underlying disorder.
How important is thymus gland?
The thymus serves a vital role in the training and development of T-lymphocytes or T cells, an extremely important type of white blood cell. T cells defend the body from potentially deadly pathogens such as bacteria, viruses, and fungi.
