Mammalian facial muscles contain muscle spindles

The Anatomical Record, 2023
AbstractMuscle spindles are sensory receptors in skeletal muscle that provide information on muscle length and velocity of contraction. Previous studies noted that facial muscles lack muscle spindles, but recent reports indicate that the human platysma muscle and “buccal” muscles contain spindles.

Photogrammetry of the Muscles of Facial Expression

Cells Tissues Organs, 1988
The present study has attempted to determine the volume, square measure as well as length, width and thickness of the individual muscles of facial expression by photogrammetry. 15 fresh male head specimens were employed for a careful dissection of muscle layers. The volume was measured using the immersion procedure.

Quantitative ultrasonography of facial muscles

Muscle & Nerve, 2013
Introduction: There is no standardized method for examination of facial muscles with ultrasound. The purpose of this study was to identify those facial muscles accessible for reliable identification and to provide reference data. Methods: In healthy subjects all facial muscles were screened for visibility, separation from adjacent muscles, and ...

Sonoanatomy of the muscles of facial expression

Surgical and Radiologic Anatomy, 1988
Primary anatomic studies served for identification and differentiation of the individual mimetic muscles. As a second step, we investigated the clinical potential of ultrasound imaging to visualize the mimetic musculature in 15 volunteers. This examination technique was used to diagnose pathological alterations, especially associated with facial palsy.

Effect of Unilateral Partial Facial Paralysis on Periosteal Growth at the Muscle-Bone Interface of Facial Muscles and Facial Bones

Plastic and Reconstructive Surgery, 2003
In a previous study, the influence of the midfacial musculature upon growth and development of the maxilla and mandible was established macroscopically. Dry skull measurements revealed a reduced premaxillary, maxillary, mandibular, and anterior corpus length with a simultaneous increase in mandibular ramal height on the paralyzed side.

Muscle-Nerve-Muscle Grafting for Facial Reanimation in Rats

Annals of Otology, Rhinology & Laryngology, 2017
Objective: Facial paralysis is a devastating condition leaving patients with a myriad of aesthetic and functional consequences. Muscle-nerve-muscle (MNM) neurotization is a reinnervation technique that involves implanting an autogenous nerve graft as a conduit between an innervated “donor” muscle and a denervated “recipient” muscle. We investigated the

Myoglobinopathy affecting facial and oropharyngeal muscles

Neuromuscular Disorders, 2022
Myoglobinopathy is a rare autosomal dominant myopathy that manifests in adulthood with proximal and axial weakness and variable respiratory and cardiac failure. Muscle pathology features associated with myoglobinopathy include characteristic sarcoplasmic bodies in skeletal and cardiac muscles.

Facial muscle spasms: An Australian study

Australian and New Zealand Journal of Ophthalmology, 1998
Abstract Purpose: A group of patients suffering from blepharospasm, hemifacial spasm and Meige's syndrome were surveyed to determine the delay from the onset of their condition until a correct diagnosis was reached, the attitudes of practitioners towards them and their condition, the effect of their condition on their lifestyle and the effects of ...

Morphology of Denervated Human Facial Muscles

ORL, 1984
17 biopsies of denervated facial muscles, the zygomatic, the orbicularis oris and the levator labii muscles, showed atrophic myofibers in most cases. There was loss of fiber typability when applying the NADH, the MAG and the alkaline ATPase reactions.

Searching for proprioceptors in human facial muscles

Neuroscience Letters, 2017
The human craniofacial muscles innervated by the facial nerve typically lack muscle spindles. However these muscles have proprioception that participates in the coordination of facial movements. A functional substitution of facial proprioceptors by cutaneous mechanoreceptors has been proposed but at present this alternative has not been demonstrated ...
