Connections between the facial and trigeminal nerves: Anatomical basis for facial muscle proprioception [PDF]

JPRAS Open, 2017
Proprioception is a quality of sensibility that originates in specialized sensory organs (proprioceptors) that inform the central nervous system about static and dynamic conditions of muscles and joints.

Human faces are slower than chimpanzee faces. [PDF]

PLoS ONE, 2014
While humans (like other primates) communicate with facial expressions, the evolution of speech added a new function to the facial muscles (facial expression muscles).

Congenital partial absence of the facial muscles

British Journal of Plastic Surgery, 1998
Facial asymmetry in a newborn infant suggests various diagnoses, including birth trauma and congenital hemifacial microsomia. But congenital absence or hypoplasia of facial muscles has not been known except for the depressor anguli oris muscle (DAOM). The authors' experience with surgical treatment of congenital hypoplasia of the risorius, zygomaticus ...

High-resolution surface electromyographic activities of facial muscles during mimic movements in healthy adults: A prospective observational study

Frontiers in Human Neuroscience, 2022
ObjectivesSurface electromyography (sEMG) is a standard tool in clinical routine and clinical or psychosocial experiments also including speech research and orthodontics to measure the activity of selected facial muscles to objectify facial movements ...

Ultrasound Imaging of the Facial Muscles and Relevance with Botulinum Toxin Injections: A Pictorial Essay and Narrative Review

Toxins, 2022
High-resolution ultrasound is preferred as the first-line imaging modality for evaluation of superficial soft tissues, such as the facial muscles. In contrast to magnetic resonance imaging and computed tomography, which require specifically designated ...

Keeping up appearances: Don’t frown upon the effects of botulinum toxin injections in facial muscles

Clinical Neurophysiology Practice, 2023
Aesthetic use of low doses of Botulinum toxin (BoNT) injections into the facial muscles has become a leading non-surgical aesthetic treatment worldwide to reduce facial wrinkles, including glabellar lines, forehead lines, and periorbital wrinkles. Within

Atlas of voluntary facial muscle activation: Visualization of surface electromyographic activities of facial muscles during mimic exercises.

PLoS ONE, 2021
Complex facial muscle movements are essential for many motoric and emotional functions. Facial muscles are unique in the musculoskeletal system as they are interwoven, so that the contraction of one muscle influences the contractility characteristic of ...

Electromyography of Extrinsic and Intrinsic Ear Muscles in Healthy Probands and Patients with Unilateral Postparalytic Facial Synkinesis

Diagnostics, 2022
There are currently no data on the electromyography (EMG) of all intrinsic and extrinsic ear muscles. The aim of this work was to develop a standardized protocol for a reliable surface EMG examination of all nine ear muscles in twelve healthy ...

Newly identified axon types of the facial nerve unveil supplemental neural pathways in the innervation of the face

Journal of Advanced Research, 2023
Introduction: Neuromuscular control of the facial expressions is provided exclusively via the facial nerve. Facial muscles are amongst the most finely tuned effectors in the human motor system, which coordinate facial expressions.
