    IX.—ARTICULATIONS OF THE PHALANGES. The preceding remark equally applies to these articula- tions. THE MUSCLES. * Explanation. The — dash divides the origin from the insertion. Nervous supply is indicated by ( ) brackets. Action of muscle is indicated by [ ] brackets, and if a muscle has two points on which it acts, a applies to action from origin on point of insertion, and b applies to action from insertion on point of origin. F signifies that the attachment is fleshy. T ,, ,, tendinous. A ,, ,, aponeurotic. A combination of any of these attachments may occur. MUSCLES AND FASCI.E OF THE HEAD AND NECK. The superficial fascia in the epicranial region and on the face is closely united to the skin, slightly developed, except between bellies of occipito-frontalis muscle. At the back part it becomes continuous with superficial fascia of posterior muscles of the neck, and descends laterally over the temporal fascia, where it envelops the external muscles of auricle, and the superficial temporal vessels and nerves. In the neck it is loose and fatty, as over rest of body. EPICRANIAL REGION. ^'•^ Occipito-frontalis : Frontal part. Has no bony attach- ments, blends with orbicularis palpebrarum, pyramidalis nasi and corrugator supercilii(F)—epicranial aponeurosis(A) (Facial). Occipital part. Outer § superior curved occi- pital lines, mastoid processes(FT)—epicranial aponeurosis, which is attached behind to curved line between fleshy heads(A). (Posterior auricular branch of facial.) [Frontal part wrinkles forehead horizontally. Occipital part removes the wrinkles; acting alternately the two parts move scalp.] Epicranial aponeurosis unites frontal and occipital muscles,
