Thus, the fingers are flexed and extended by muscles whose bodies are located in the forearm, and whose contractions are transmitted to the finger bones by tendons attached to the bones at one end and to the muscles at the other. The extensor tendons on the back of the hand can be readily followed to their origin and insertion. It is evident that such an arrangement gives much greater delicacy and ease of manipulation to the hand than would be the case if each finger were attached directly to a muscle. This tendon method of attachment is especially noticeable in the limbs where bulkiness is most undesirable. If we boil a piece of the 'â ' dissected muscle or a piece of lean beef (the bellied muscle of a beef creature), it readily separates into a series of smaller prism- shaped bundles, and these may be easily picked apart. Examination of one of these prism-shaped bundles shows it to be covered with the same sheathlike perimysium which in fact is merely a partitionlike extension of the outer peri-. 1^âBundles of striated muscles cut across ;/,/, several bundles bound togetber to make up tbe main Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Eddy, Walter Hollis, b. 1877.
