The human body contains over 650 skeletal muscles, each with a specific name and function. The prominent and important muscle that rounds the cap of the shoulder, often referred to as the muscle on the outside of your upper arm, is the deltoid.

The upper extremity contains 30 bones, a third of all the bones in the human body, from the shoulder to the fingertips. This intricate structure allows for a wide range of movement, so when asked, "**What is an example of an upper extremity?**", the answer includes the shoulder, arm, forearm, wrist, and hand.
