överarmsvävnaden

Overarmsvävnaden, often translated as upper arm tissue, refers to the collection of biological materials that constitute the human upper arm. This includes the skin, subcutaneous fat, muscles, bones, nerves, and blood vessels found in this region. The primary muscles of the upper arm are the biceps brachii, triceps brachii, and brachialis, which are responsible for flexion and extension of the elbow joint and contribute to shoulder movement. The humerus is the single bone of the upper arm.

The skin of the upper arm provides a protective outer layer and contains sweat glands and hair follicles. Beneath the skin lies the subcutaneous fat, which varies in amount and distribution among individuals and contributes to insulation and energy storage. The muscles are responsible for movement and are crucial for activities involving lifting, pushing, and pulling. Nerves, such as the radial, ulnar, and median nerves, innervate the upper arm muscles and transmit sensory information from the skin to the brain. A rich network of blood vessels, including the brachial artery and vein, supplies oxygen and nutrients to the tissues and removes waste products.

Injuries to the overarmsvävnaden can range from minor bruises and muscle strains to more severe fractures of the humerus or nerve damage. Conditions affecting this tissue can impact a person's ability to perform everyday tasks and may require medical intervention for diagnosis and treatment. The composition and health of the overarmsvävnaden are influenced by factors such as age, genetics, diet, and physical activity levels.
