    00:01 Welcome to this presentation on Facial Muscles and Muscles of Mastication.

    00:06 We'll begin by looking at the four groups or categories of facial muscles.

    00:13 The first group is referred to as the epicranial group.

    00:16 This would include the occipitalfrontalis muscle.

    00:20 Then we have the circumorbital and palpebral a group of facial muscles.

    00:25 This would that include the orbicularis occuli and the corrugator supercilii.

    00:32 The third category or group of facial muscles is the nasal group.

    00:36 This would include the procerus, nasalis, and depressor septi.

    00:42 And then the largest group of facial muscles falls into the buccolabial group.

    00:50 Here we have the levator labii superioris alaeque nasi, labii superioris, zygomaticus major and minor, levator anguli oris, mentalis, risorius, depressor labii inferioris, depressor anguli oris, the buccinator, orbicularis oris, and then the last muscle that falls into the buccolabial group is the platysma.
