Lymphoid tissue that appears as a swelling of the mucosa in the oral cavity is called a(n) .

There are choices for this question namely: 

A) tonsil
B) thymus
C) Peyer's patch
D) appendix

The correct answer is "tonsil". Tonsils are lymphoid tissue that is found in the oral mucosa. The tonsils are arranged in a ring-like fashion called the Waldeyer's ring. This ring comprises of two tubal tonsils, two palatine tonsils, one adenoid tonsil, and one lingual tonsils. In cases of infection involving the oral mucosa and the pharynx, the tonsils become inflamed as well and the condition is called acute tonsillopharyngitis.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
