Thymus is found in human body_.
Correct answer: B. In the mediastinum of the upper thorax
- A. In the medulla oblongata
- B. In the mediastinum of the upper thorax
- C. Both A & B
- D. None
Explanation
Yes, the thymus gland is located in the mediastinum, which is the central compartment of the thoracic cavity. It sits just behind the sternum and in front of the heart, extending from the base of the throat to the front of the heart. It plays a crucial role in the development of the immune system, particularly in the production and maturation of T-lymphocytes (T-cells), which are vital for adaptive immunity. The activity and size of the thymus are greatest during childhood and adolescence, after which it gradually shrinks and is replaced by fatty tissue.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
