Document Summary

* muscles are in compartments that are surrounded by deep fascia. Muscles in the same compartment are surrounded by fascia to allow them to move relative to each other/have a similar function or the same function (in general they have the same innervation) * muscles in different compartments are encased in fascia to allow them to move across each other. * fascia can be specialised fascia of the arm: brachial fascia. * interosseous membrane binds radius and ulna together. * retinaculae binds down tendons (prevents bow stringing) * flexor retinaculum forms roof of the carpal tunnel. Contents: tendons (& synovial sheath), median nerve. * superficial (extrinsic muscles of the back) (cid:374)ot (cid:858)true(cid:859) (cid:271)a(cid:272)k (cid:373)us(cid:272)les. All attach to and act on the upper limb. * these muscles attach to the trunk and attach to the scapula or humerus to move the shoulder girdle. * latissimus dorsi involved in extension of the arm -attach the humerous.
