ANATOMY AND PHYSIOLOGY. 
Anatomy is simply a description of the body and its several 
parts. The human system may for the better understanding 
be classed into seven’ divisions; 1. the bones; 2. ligaments ; 
3. muscles; 4. blood.and lymph vessels ; 5. nerves and centres ; 
6. organs; 7. skin and appendices. The bones number 200, 
and are arranged as follows: in the spine, 26; in the head 
and face, 22; the ribs, breast-bone, and a smaller one 
beneath the root of thetongue, called the hyoid, 26 ; in the upper 
extremities, 64; in the lower, 62. There arethree very small 
bones in the ear, and some developed in the tendons, with the 
teethandare not included inthisnumber. Bonesare divided into 
four classes—long, short, flat, and irregular. The long ones 
are the levers and supports of the body; the short ones give 
strength and compactness to the joints; the flat for protection 
of vital parts and attachments of muscles; and the irregular, 
as the vertrebree, for strength, muscular attachment, and 
protection of the spinal cord. The bones that form the skull 
and face are in adult life so closely united that a superficial 
observer would conclude that these were but two, the skull and 
lower jaw. Closer inspection, however, will show the line of 
junction called sutures, the edges of which are serrated like 
the teeth of a saw, so that the bones dovetail into each other. 
The outside bones of the skull are six, and are named the 
frontal or brow bone, the temporal, which contains the organs 
of hearing, the sides and top of the head are formed by the two 
parietal bones; while the occipital forms the back and lower 
portion of the head, it rests upon the spine and transmits the 
cord and its membrane. Inside the skull are the sphenoid 
and ethmoid; they, with the occipital, unite to form its
