Muscles of upper limbs from "summary" of Bd Chaurasia's Human Anatomy, Volume 1 by B. D. Chaurasia
The upper limbs of the human body contain various muscles that are responsible for movement and stability. These muscles can be categorized into different groups based on their location, function, and attachment points. The muscles of the upper limbs can be broadly classified into two main groups: extrinsic and intrinsic muscles. The extrinsic muscles originate from outside the upper limb and insert into various bones of the limb, while the intrinsic muscles are located entirely within the upper limb itself. The extrinsic muscles of the upper limb include muscles such as the deltoid, pectoralis major, and latissimus dorsi. These muscles are responsible for movements of the shoulder joint, arm, and forearm. They play a crucial role in activities such as lifting, pushing, and pulling. On the other hand, the intrinsic muscles of the upper limb are responsible for fine movements and precision. These muscles are located within the hand and wrist and include muscles such as the flexor digitorum superficialis, extensor pollicis longus, and abductor pollicis brevis. These muscles work together to allow for intricate movements of the fingers and thumb. Additionally, the muscles of the upper limb can also be categorized based on their actions. For example, muscles that flex the elbow joint are known as flexors, while muscles that extend the elbow joint are known as extensors. Similarly, muscles that abduct the arm are known as abductors, while muscles that adduct the arm are known as adductors.- The muscles of the upper limbs are essential for various activities and movements of the arm, forearm, hand, and fingers. These muscles work together to provide strength, stability, and dexterity to the upper limb, allowing for a wide range of movements and functions.
