Appendicular muscles refer to a series of muscles located in the limbs, specifically the arms and legs, that support and facilitate movement and stability in these areas. These muscles are a vital component of the musculoskeletal system, playing a crucial role in the execution of various bodily movements such as walking, running, gripping, and lifting.
In the upper limbs, the appendicular muscles encompass the muscles of the shoulder, upper arm, forearm, and hand. These include muscles like the deltoid, biceps, triceps, forearm flexors and extensors, and the intrinsic hand muscles. Collectively, these muscles allow for a wide range of movements including reaching, throwing, and grasping objects.
On the other hand, the appendicular muscles in the lower limbs are responsible for movements such as walking, running, jumping, and squatting. This group includes muscles such as the quadriceps, hamstring muscles, calf muscles, and the muscles of the foot. These muscles provide stability, balance, and coordination during various locomotor activities and help maintain an upright posture.
The appendicular muscles work in tandem with the axial muscles, which consist of the core muscles of the body, including those located in the back, abdomen, and hips. Together, the appendicular and axial muscles collaborate to generate and control movements throughout the body, supporting overall physical function and mobility.
