The large triangular muscle of the shoulder -- the deltoid -- is one of great strength, as in fact are all the muscles of the arm.  If you grasp the arm tightly just above the elbow joint, and then bend the forearm, you will feel the biceps muscle of the arm become firm, hard and prominent; now straighten it again and it becomes relaxed, whilst the muscles on the back of the arm become hard and prominent. The muscles of the forearm are the flexors and pronators; that is, they flex the arm and turn the palm downward.  In each upper extremity or arm there are fifty-three muscles, and we observe here the nicest and most economical method of packing away the muscles that could be improvised, securing strength, giving elegance to its form and shape and facilitating its mobility.

Additional Articles from the Book of Medicine:

• Duty of the Throat
  
  

  Duty of the Throat.- the muscular bands of the throat now grasp it and pass it down the gullet into the stomach, beyond our control.  Here it comes into contact with the gastric juice, undergoes the churning motion of the stomach, discarded over by the pylorus, thoroughly saturated in mixed before entering into the intestinal tract, where it is subjected to the action of the file, the pancreatic juice and the intestinal fluid each with its special duty to perform.

   

  Again nothing terribly exciting here in this section but the next one will take us into “Nature’s Treasures Opened to Man”.

• Healthy Locations
  
  

  We are just scratching the surface of our review into the History of the Book of Medicine, literally covering the foundation perspective. As we move more into the diagnosis areas and more we will really start to get to some peculiar aspects of the views from the past.

  One thing I’m interested to see and learn is whether or not medical doctors suggested healthy climates. Today, we often see people moving to Florida or Phoenix even for their health. Snow birds from Canada fly south for the winter to escape the cold and get some sun to metabolize vitamin D, escaping to luxurious and inexpensive Orlando vacation rentals selecting condos or villas that are air conditioned but close to all the local attractions.

  Its the weather and climate that keep people flocking back, hoping to get a reprieve and at least feel healthier. So I will be keenly interested to learn if this perspective is new.

• Muscles of the Thigh and Leg
  
  

  Muscles of the Thigh and Leg.-turning to the next colored illustration, with a graphic of a full view of the deeper muscular arrangements play together with a striking his harvests applied to the lower extremity.  Delete these beautiful, silvery threads are the wires which carry the behest of the will to the muscular lovers, and whose commands the muscles probably obey; and give to the leg is wonderful and diversified endowments.  To stand erect is a very difficult and complex attack, in the process of forming is a no less difficult for complex function.  Few persons ever realize the peril involved in walking, and it has only become safe by constant practice.

  We are finally finishing up the last sections of the first book and I will be glad to get beyond the basic descriptions of images of the human body and move onto the last century view on weight loss pills (or roots) and other pragmatic cures for the common and uncommon ailments of humans.
