THE MUSCULAE SYSTEM. 



2. Movements of the Head. The movements of the head are flexion and extension, at the 

 occipito-atlaiitoid articulation ; lateral movement and rotation at the atlanto-epistropheal joint. 



Movements of the Pelvis. The movements of the pelvis (as in locomotion) are partly 

 caused by certain of the muscles of the back. Those muscles, which are attached to the vertebral 

 column or the ribs on the one hand, and to the hip bone on the other, produce the movements 

 (flexion, extension, and lateral movement) of the whole pelvis. In addition, the muscles passing 

 between the hip bone and femur, in certain positions of the lower limb, assist in these 

 movements. 



THE FASCIAE AND MUSCLES OF THE HEAD 



AND NECK. 



FASCLE. 



The superficial fascia of the head and neck possesses certain features of special 

 interest. Over the scalp it is closely adherent to the skin and subjacent gales 

 aponeurotica and contains the superficial vessels and nerves. Beneath the skin o 

 the eyelids it is loose and thin and contains no fat. Over the face and at the sid* 

 of the neck it is separated from the deep fascia by the facial muscles and the 

 platysma. Between the buccinator and the masseter it is continuous with a pa( 

 of fat (corpus adiposum buccce} occupying the interval between those muscles.
