If we review the etymological evolution of arm, we will notice that the journey begins in the Greek term brachíōn, which derived from the Latin word brachĭum before reaching our language.
According to DigoPaul, the concept is used to name the body limb that goes from the shoulder to the hand. In some cases, the notion specifically refers to the sector that extends between the shoulder and the elbow.
For example: “Today I had to carry several heavy bags and now my arms hurt”, “When the man grabbed her arm, the girl started screaming”, “The referee should have taken a penalty since the ball hit her arm right of the American defender ”.
If we focus on the arm as said segment of the upper limb, we can say that it is formed by the humerus bone (articulated with the ulna, radius and scapula) and by muscles such as the pectoralis minor, the pectoralis major, the trapezius, the deltoids, biceps brachii, and triceps brachii, among others.
Specifically, we have to show that the skeleton of the arm is made up of three clearly differentiated parts:
-The arm, where the humerus bone is found, as well as muscles such as the triceps and biceps.
-Forearm. It “joins” the previous one through what is the elbow. It is made up of two bones such as the ulna and the radius.
-The hand, which is made up of four different parts: the carpus, metacarpus, palm of the hand and the phalanges.
There are many injuries and illnesses that can affect the arm. However, among the most common are the following:
-Tendinitis, which occurs when an inflammation of the tendon occurs. It usually affects, above all, the wrist and they are really common among certain athletes. Thus, for example, one speaks of the “tennis elbow”.
-Fracture. Without a doubt, this other situation that affects the arm is also very common, which is a break in one of its bones. A fall, an accident or even a sports injury are some of the causes that can lead to it.
Also known as arms to support with chairs, the branches of trees and candlesticks holding lights a spider: “Joan poured a glass of juice on the arm of the chair”, “An arm of the tree detached and fell on a car “, ” This spider has twenty arms.
In a symbolic sense, one speaks of an arm to make mention of different types of ramifications or divisions: “The boat sank in one of the arms of the Paraná River”, “In those years, the Communist Party had an armed arm”, “The The judicial branch is the state power that generates the most mistrust in the population ”.
One of the most popular expressions that exist in Spanish makes use of the term that now occupies us. We are referring to “give the arm to twist”. Apparently this same has its origin in the game of “pulse” and means that someone gives. An example of use is the following: After the advantages of the merger were exposed to her, the owner of the company gave her arm to twist and accepted the agreement.
