Musculature of the face. Wikigallery - the largest virtaul gallery in the world with more than 150000 on display. Always open and always free. These muscles are also called Mimetic muscles.

The facial muscles are concerned with an array of facial expressions other functions. These muscles are different from other muscle organizations in lacking of deep fascia beneath the skin of face. Neck connects the head to the trunk.

Somatic muscle fibers to the muscles of the face scalp and outer ear enabling the muscle movements that comprise facial expressions. The sensory part of the nerve enables and augments some aspects of taste and sound Standring 20052 The facial nerve receives impulses from. Underlying the subcutaneous tissue is the musculoaponeurotic layer.

This in essence is the layer of mimetic musculature of the face enclosed in its fibrous muscle fascia on the superficial and deep surfaces. In areas where the muscles have undergone fibrous involution the SMAS remains as the fibrous aponeurotic component only. 1 All are inserted into the skin of the face 2 All are supplied by the muscular branches of the facial nerve 3 All produce facial expression 3.

The craniofacial muscles receive their innervations from the branches of the FACIAL NERVE. They are grouped as. The surface anatomy doesnt always reveal the musculature beneath depending on the thickness of subcutaneous fat especially on the cheeks.

The muscles come most into play in expression and you will also observe the connection between muscle groups and expression lines or wrinkles.

With two additional plates. And explanatory notes by William Robertson. The human face has the greatest mobility and facial display repertoire among all primates.

However the variables that account for this are not clear. Humans and other anthropoids have remarkably similar mimetic musculature. This suggests that differences among the mimetic muscles alone may not account for the increased mobility and facial display.

Over time chronic clenching of the jaw leads to hypertrophy of masseters and temporalis musculature causing the face to take on a masculine and square appearance. Patients commonly present to dermatology cosmetic practices wishing to have a more slim softer appearing face. Locations for botulinum toxin injection in the face.

INTRODUCTION The facial musculature is a three-dimensional 3-D assem-blyofmultiplesmallmusclebundlesandsheetlikemusclefiber arrays Fig. The independently controlled subcomponents of this complex muscle system are of great importance for the.

The objective of this study was to systematically characterize motor units MUs of the musculature of the lower face. MU endplate positions and principal muscle fiber orientations relative to facial landmarks were identified. This was done by the analysis of motor unit action potentials MUAPs in the surface electromyogram.

81 have a similar facial musculature but the former lack two muscles that are usually present in the latter the sphincter colli superficialis and the mandibulo- auricularis. Mammals Figure 1 in contrast to other terrestrial vertebrates possess facial muscles that directly insert at the outer ears the vibrissae and the skin allowing for active signaling and thus direct facial communication.
