Yläraajalihakset

Yläraajalihakset, also known as upper body muscles, are a group of muscles located in the upper part of the human body. They play a crucial role in various movements and activities, including pushing, pulling, and lifting. The upper body muscles can be further categorized into two main groups: the upper body proper and the shoulder girdle.

The upper body proper includes the muscles of the chest, back, arms, and shoulders. The chest muscles, also known as the pectoral muscles, are responsible for movements such as pushing and lifting. The back muscles, including the latissimus dorsi and rhomboids, are involved in pulling movements and maintaining posture. The arm muscles, such as the biceps and triceps, are essential for gripping and manipulating objects. The shoulder muscles, including the deltoids and rotator cuff muscles, are responsible for shoulder movement and stability.

The shoulder girdle, also known as the pectoral girdle, consists of the clavicle (collarbone) and the scapula (shoulder blade). These bones provide a stable base for the upper body muscles and allow for a wide range of movements. The shoulder girdle muscles, including the rhomboids and serratus anterior, are responsible for stabilizing and moving the shoulder blade.

Yläraajalihakset are an essential part of the human body, providing the strength and mobility needed for daily activities and athletic performance. Proper exercise and nutrition are important for maintaining the health and function of the upper body muscles.
