2020, Annals of AnatomyCitation Excerpt :In our opinion, regarding its function in transferring mimic muscle contraction to the skin SMAS three dimensional multiplanar fibro-adipose meshwork concept described by this study results is justified. The platysma is a multifunctional mimic muscle that covers the cervical area with histochemical constitutional similarities to the zygomaticus major, depressor anguli oris, levator labii superioris and levator anguli oris muscles, reflecting the phasic activity that occurs during the expression of fast emotional reactions (Happak et al., 1988; May et al., 2018; Som and Laitman, 2017). The space between the platysma muscle and the skin was described in former investigation as the superficial fascia (Lindner, 1986).
The facial motor system
2014, Neuroscience and Biobehavioral ReviewsCitation Excerpt :On the other end of the spectrum, facial muscles with the highest representation of slow-twitch fiber types (around 50% of the total pool of fibers) are the frontalis, the corrugator supercilii and the depressor labii inferioris (Freilinger et al., 1990; Goodmurphy and Ovalle, 1999; Happak et al., 1988). The remaining muscles, namely the platysma, the mentalis, the depressor anguli oris, the orbicularis oris, the levator anguli oris, the zygomatici, and the levator labii superioris have an approximate fast-slow fiber type ratio of 2:1 (Dittert and Bardosi, 1989; Freilinger et al., 1990; Happak et al., 1988; Schwarting et al., 1982; Stål et al., 1987, 1990). One peculiarity of facial muscles of unclear functional significance that was described for the the zygomatici and the orbicularis oris muscles is the presence of fibers with intermediate staining characteristics between type IIA and type IIB fibers, which have been named type IIAB (Stål et al., 1987, 1994) and which are characterized by a myosin heavy chain isoform that is unique to facial muscles (Stål et al., 1994).
Denervation pattern of three mimic muscles in Bell's palsy
2006, Neurophysiologie CliniqueCitation Excerpt :The selective sparing of these fibers can be attributed to their relatively smaller diameter and/or to their central intraneural topography, which are both known to act protectively [1,15]. However, the first point is supported only by an indirect indication concerning the very small diameter of the OO muscle fibers compared to that of the other mimic muscles [6], and, despite some earlier opinions favoring a central intraneural course of these facial nerve fibers [14,3], most authors agree that they are diffusely distributed [8,19,16,13]. In this study absence of fibrillation in OO, was found to be correlated with a better prognosis of the palsy and with a significantly better CMAP ratio in all three muscles tested.
