The human elbow is a synovial hinge joint that allows for bending and straightening of the arm, a motion controlled by a fascinating push-pull relationship between muscle pairs. Understanding what is the agonist and antagonist of the elbow is key to grasping the mechanics of how our bodies move and function efficiently. This article will delve into this crucial biomechanical partnership.

According to biomechanics experts, rotation is a body movement where a bone moves around a central axis, with specific movements categorized based on direction. This guide will explore **what are the four types of rotation**, examining how this fundamental concept varies across different scientific and medical disciplines.

In anatomy, movement is meticulously defined by its relationship to the body's midline, or central axis. This standardized directional terminology is precisely why a rotational movement toward the center of the body is called internal rotation, distinguishing it from all other motions.

The scapula, or shoulder blade, is anchored in place by a complex network of muscles, allowing for its remarkable mobility. This critical bone forms the foundation for two primary joints that are essential for arm movement, prompting the question: What are the two main articulations of the scapula?
