deltoideuslihakset

Deltoideuslihakset, also known as the deltoid muscles, are a group of three muscles located in the shoulder region of the upper body. They are named for their triangular shape and are responsible for a wide range of movements, including shoulder abduction, flexion, and extension. The deltoid muscles are composed of three distinct heads: the anterior, lateral, and posterior deltoid. The anterior deltoid is responsible for shoulder flexion, the lateral deltoid for shoulder abduction, and the posterior deltoid for shoulder extension. These muscles are innervated by the axillary nerve and are a key component of the shoulder's rotator cuff. The deltoid muscles play a crucial role in various daily activities, such as lifting objects, throwing, and reaching. They are also a common target for physical therapy and rehabilitation exercises due to their involvement in many shoulder-related injuries and conditions. Proper strength and function of the deltoid muscles are essential for maintaining overall shoulder health and mobility.
