The word "scapular reflex" is spelled as /ˈskæpjʊlər ˈriːflɛks/. The first part of the word, "scapular," is pronounced with a short "a" sound as in "cat," followed by the syllable "pul" which is pronounced with a short "u" sound as in "cup." The second part, "reflex," is pronounced with a long "e" sound as in "bee," followed by the syllable "-lex," pronounced with a short "e" as in "let." This reflex is tested by tapping the shoulder blade and observing the resulting movement of the arm.
The scapular reflex is an involuntary muscle response that occurs when there is a sudden and unexpected movement or stimulation of the scapula, which is also known as the shoulder blade. This reflex is a protective mechanism of the body that helps maintain balance and stability during unexpected situations.
When the scapular reflex is triggered, the muscles surrounding the scapula contract rapidly and involuntarily, causing the shoulder blade to move in a specific direction. This reflexive response is typically seen in response to sudden jolts, bumps, or other external stimuli that affect the scapula region.
The scapular reflex involves the activation of various muscles, including the rhomboids, trapezius, and serratus anterior. These muscles work together to coordinate the movement and stabilization of the scapula, contributing to the overall mobility and function of the shoulder joint.
The scapular reflex is an important part of the body's protective responses, as it helps to prevent injury and maintain stability during sudden impact or movement. It allows for a quick adjustment of the shoulder blade position to maintain balance and support weight-bearing activities.
In summary, the scapular reflex is an involuntary muscle response to sudden and unexpected movement or stimulation of the scapula. It serves as a protective mechanism that aids in maintaining balance, stability, and overall shoulder joint function.
Contraction of any of the scapular muscles following scratching or otherwise irritating the skin covering them.

The etymology of the word "scapular reflex" can be broken down as follows:
1. Scapular: The term "scapular" comes from the Latin word "scapula", which means shoulder blade. It is derived from the Proto-Indo-European root "skabh-", which means to scrape or scratch. This word refers to the large, flat bone on each side of the upper back that connects the humerus (upper arm bone) with the clavicle (collarbone).
2. Reflex: The word "reflex" is derived from the Latin word "reflexus", which means bending back. It is formed from the prefix "re-", meaning back, and the verb "flectere", which means to bend. In the context of medicine, a reflex refers to an involuntary and automatic response of the body to a specific stimulus.
