SYSTEMATIC SYNTHESIS OF TISSUES INTO ORGANS. 243 



481. THE HAND THAT SWINGS A GATE BY ACTING 

 NEAR THE HINGE, moves but a very short distance ; so 

 the muscle contracts but a little to produce much motion. 



482. A MUSCLE CAN CONTRACT but a small part of its 

 length with profit, while the exertion necessary to pro- 

 duce the effect can be made in an instant, and much time 

 saved in producing motion. 



483. Inf. THE WHOLE BODY is CONSTRUCTED with reference to sav- 

 ing time in doing that which is merely mechanical 



484. IT ALSO IMPROVES PERSONAL APPEARANCE to 



have muscles in many instances attached near the joint, 

 since thus a compact and graceful form is exhibited. 



485. Remark. We may now hastily take a view of the muscles 

 of the different members of the Body, for the purpose of noticing any- 

 thing particularly interesting, and for the purpose of illustrating some 

 of the facts already stated. But it will not be worth while to enter 

 into a detailed description of all the muscles, as nearly all of them are 

 illustrated by the plates, and the description of them in connection with 

 the plates is sufficient for all ordinary purposes. 



SPECIAL MUSCLES. 



Muscles of the Head. 



486. THE MUSCLES OF THE HEAD ARE DIVIDED into 

 those of the Cranium, Facium, and Organs of Sense. 



Remark. Those that move the head upon the spinal column are 

 classed with those of the neck. 



487. THE OCCIPITO FRONTALIS is the name of a 

 broad thin muscle that extends from the back of the 

 cranium to the front of it, having two fleshy parts, one 

 at the back and the other in the forehead, the connecting 

 part being a broad aponeurosis, some of the fibres of 

 which closely connect with those of the scalp, on ac- 

 count of which this muscle can move the scalp. The 

 contraction of the front part of it wrinkles the forehead. 

 It has a line of tendon extending from front to back,
