submental
inguinal
superficial cervical
superficial cubital

Explanation:

• Question 26: The thymus is a primary lymphatic organ. It is where T - lymphocytes mature. The thalamus is part of the brain (not lymphatic), the thyroid is an endocrine gland (not primary lymphatic), and the spleen is a secondary lymphatic organ.
• Question 27: The superficial cubital nodes (also known as the epitrochlear nodes) drain lymph from the hand and forearm, including the thumb. Submental nodes drain the chin and lower lip area, inguinal nodes drain the lower limb and external genitalia, and superficial cervical nodes drain the neck region.

Answer:

• Question 26: thymus
• Question 27: superficial cubital
