Document Summary

Muscle properties: skeletal (striated) muscle, force producing, cause and control movements of our body segments. Needs an intact nerve supply to contract. Relies on conscious direction form the brain. Location and organization of the skeletal muscle tissue relative to the bones and articulations dictate movements. All skeletal muscle have at least 2 attachments. Origin: attachment of the muscle to the bone, more proximal attachment, on the more stable bone. Insertion: distal attachment, usually tendinous, attached to the more moveable bone. Important biomechanical characteristic: location of attachment, angle of attachment, number of articulations crossed. Muscle group is named off the joint movement that the muscles are able to cause. Factors in naming a muscle: their situation, brachialis, pectoralis, supraspinatus, their direction, rectus, o(cid:271)li(cid:395)ue(cid:859)s, transverse abdominis, their action, flexors, extensors, their shape, deltoideus, trapezius, rhomboideus, the number of division, biceps, triceps, quadriceps, point of attachment, sternocleidomastoids.
