The ____________ is sometimes called the "funny bone" because of the tingling sensation (pain) one feels if the ____________ is
Alex

Answer:

<u>Ulnar nerve</u> is also called funny bone and feels tingling sensation if <u>humerus </u>is bumbed. <u>Medial epicondyle</u> passes underneath this bony structure.

Explanation:

The funny bone isn't actually a bone, its actually a nerve that touches your humerus.It is the ulnar nerve, which travels down the arm posteriorly and eventually reaches the "cubital tunnel" and at this location (between the trochlea and medial epicondyle of humerus),  ulnar nerve is called funny bone.

The nerve is relatively unprotected at this place.

A blow here may produce a tingling or a numbing sensation throughout the forearm and hand.

Hence, <u>Ulnar nerve</u> is also called funny bone and feels tingling sensation if <u>humerus </u>is bumbed. <u>Medial epicondyle</u> passes underneath this bony structure.
