what are the two parts of the skull?
skull roof
the skull is a bony structure that forms the head in vertebrates. it supports the structures of the face and provides a protective cavity for the brain. the skull is composed of two parts: the cranium and the mandible. in humans, these two parts are the neurocranium and the viscerocranium or facial skeleton that includes the mandible as its largest bone. the skull forms the anterior most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. in humans these sensory structures are part of the facial skeleton.

latex masks are generally made in several stages. the first stage may begin with a clay-sculpted 'positive' or 'male mold' of the character. a plaster mold is then made of the sculpture, capturing all of the detail. the plaster mold is generally made in two-pieces for a full-head mask. another popular method of creating such masks is to make a life mold of the subject in which he or she reclines in a chair, has his or her hair protected by a skull cap, and has alginate placed over the head (breathing facilitated, typically, through straws placed in the nostrils). this is usually done in two parts—front and back. the division may be established through the use of a template of the top-to-bottom outline of the head and neck of the person being 'cast,' with a parting compound such as a lubricant being placed on the template to enable the easy separation and removal of the two parts of alginate. after the two parts have been removed and have been allowed to dry, they are re-united to form a 'female' mold into which plaster may be poured to re-create the image of the original cast head and features, in 'male' or 'positive' form.
