![]() Why not cut your time in half by studying with our upper limb muscle anatomy chart? They'll teach you everything you need to know about attachments, innervations and functions. There's a lot to learn about the anatomy of the upper limb muscles. It is important to note that the scapula does articulate with the acromial end of the clavicle forming the acromioclavicular joint (AC joint), as well as the humeral head with the scapular glenoid cavity (fossa) which forms the glenohumeral joint. The scapula has no direct bony attachments to the thorax, so it is held in place and stabilized through muscular attachment. which stands for supraspinatus, infraspinatus, teres minor, and subscapularis. The acronym for the rotator cuff is S.I.T.S. However, the scapula is integral to the movement of the shoulder via the rotator cuff and additional muscles. It may seem strange that it is included in the anatomy of the upper limb. The scapular region lies on the posterior surface of the thoracic wall. Shoulder joint, Articulatio humeroscapularis We will also discuss the clinical relevance of the upper limb.Įxtensor carpi radialis longus and brevis Human hands are quite special in their anatomy, which allows us to be so dexterous and relies on muscles of the upper limb to help move it through space. The hand (manual region) is the terminal end and focus of the upper limb. In this article we will discuss the gross (structure) and functional anatomy (movement) of the muscles of the upper limb. Mnemonics: ' APB is A Friend Of Police' (thenar muscles include Abductor Pollicis Brevis, Adductor pollicis, Flexor pollicis brevis, Opponens Pollicis) Thenar eminence, Hypothenar eminence, Interossei, Lumbricals Supinator, Extensor digitorum, Extensor carpi ulnaris, Extensor carpi radialis longus and brevis, Extensor indicis proprius, Extensor digiti minimi, Brachioradialis ![]() Mnemonic: ' Pass/ Fail, Pass/ Fail, Faill' Pronator teres, Flexor carpi radialis, Palmaris longus, Flexor carpi ulnaris, Flexor digitorum superficialis, Pronator quadratus, Flexor pollicis longus, Flexor digitorum profundus Pectoralis major, Pectoralis minor, Deltoid, Latissimus dorsiīrachialis, Biceps brachii, Coraco Brachialis, Triceps brachii ![]() Mnemonic for rotator cuff muscles: Rotator cuff SITS on the shoulder Supraspinatus, Infraspinatus, Teres minor, Subscapularis, Teres major, Serratus anterior, Levator scapulae, Rhomboid major, Rhomboid minor, Trapezius Key facts about the upper limb muscles and movements Scapula In that manner of speaking, this article will explain all the anatomical aspects of the muscles of the scapula, arm, forearm and hand. It is best studied broken down into its components: regions, joints, muscles, nerves, and blood vessels.īy looking at all of the upper limbs components separately we can appreciate and compartmentalize the information, then later view the upper limb as a whole and understand how all of its parts work in unison.įor this reason, the anatomy of the upper limb from the aspect of muscles will be reviewed topographically. The upper limb (upper extremity) is truly a complex part of human anatomy.
