176 PRACTICAL ANATOMY. 



of a loose, net-like arrangement of white, fibrous tissue, 

 presenting many interstices or alveoli, generally filled 

 with fat. The deep fascia, beneath the superficial, con- 

 sists of a white, dense, aponeurotic arrangement of white, 

 fibrous tissue, free from fat and found investing the 

 muscles of the body. 



Connective tissue is the disposition of the fibres of 

 the white fibrous tissue between the different soft struc- 

 tures of the body. Muscles are generally arranged in 

 symmetrical pairs. 



MUSCLES OF THE HEAD. 

 OCCIPITO-FRONTALIS. 



Origin Superior curved line on occipital bone and 

 mastoid portion of temporal bone. 



Insertion It becomes aponeurotic and passes for- 

 ward over the cranium, and is inserted by a fleshy 

 belly into the soft structures above the orbit. 



Nerves Posterior portion by the small occipital and 



facial and anterior portion by facial. 

 ORBICULARIS PALPEBRARUM. 



Origin Internal angular process of frontal, nasal 

 process of superior maxillary and upper edge of 

 tendo oculi. 



Insertion It is a plane of fibres which surround the 

 orbit elliptically, and is inserted into the inferior 

 edge of the tendo oculi and nasal process of supe- 

 rior maxillary. 



Nerve Facial. 



CORRUGATOR SUPERCILII. 



Origin Superciliary ridge near the frontal suture. 

 Insertion Passes outward, and is inserted in the 



under surface of the orbicularis palpebrarum and 



occipito-frontalis. 

 Nerve Facial.
