Of the 40 to 100 lymph nodes demonstrable in the dissection of the normal human neck, a few are always palpable through the skin in normal living adults. Important decisions in medicine often depend on the results of such palpation.
Size. Nodes are generally considered to be normal if they are up to 1 cm in diameter; however, some authors suggest that epitrochlear nodes larger than 0.5 cm or inguinal nodes larger than 1.5 cm should be considered abnormal.

Normal Nodes.Lymph nodes can always be felt in the neck and groin. They are about the size of a bean.
Size. Nodes are generally considered to be normal if they are up to 1 cm in diameter; however, some authors suggest that epitrochlear nodes larger than 0.5 cm or inguinal nodes larger than 1.5 cm should be considered abnormal.
Cervical lymph nodes are located in the sides and back of the neck. These glands are usually very small. However, when a lymph node is greater than 1 centimeter in diameter, it is enlarged. The cervical lymph nodes sit deep inside the neck.
Healthy lymph nodes are typically pea-sized. You should not normally be able to feel them. Lymph nodes that are just below the skin may be easier to feel when they become swollen as they will become larger.
Epitrochlear nodes are best sought with the patient's elbow flexed to about 90°. The right epitrochlear area is approached by inserting the examiner's left hand from behind the patient's elbow while the examiner's right hand grasps the right wrist of the patient, supporting the forearm, as in Figure 149.2B.
Lymph nodes can be mistaken for a muscle (or artery). You must be able to roll a lymph node in two directions; up and down and from left to right.
The lymph nodes are usually painless, firm, rubbery, and movable in the surrounding tissue.
