(b) The cervico-auricularis profundus major arises from the ligamentum nucha, partly beneath and partly behind the preceding muscle. It is directed outward and is inserted into the postero-lateral aspect of the base of the ear, partly under cover of the parotido-auricularis.

The parotido-aiuricularis (s. M. auricularis inferior) is a ribbon-like muscle which lies on the parotid gland. It is thin and wide at its origin from the fascia on the lower part of the parotid gland, and becomes somewhat narrower and thicker as it ascends. It is inserted into the
