Layers

1- Skin 2- Connective tissue 3- Aponeurosis Note: Epicranial aponeurosis=occipitofrontalis Muscle+ the

galea aponeurotica .4- Loose connective tissue 5- Periosteum

Note:- the superficial 3 layers are firmly united to each other and move

as one layer.

formed of 4 bellies

**2 frontal bellies: lies anteriorly origin: from epicranial

aponeurosis Insertion: into skin of forehead

**2 occipital bellies: lies posteriorly

origin: from highest nuchal lines

insertion: into epicranial aponeurosis
