Supplies Motor Fibers To The Muscles Of The Tongue
Supplies Motor Fibers To The Muscles Of The Tongue. The superior fibres draw the tip back and down. The tongue is a muscular organ situated in the floor of the mouth.
The intrinsic tongue muscles alter the shape of the tongue and are innervated by the The palatoglossus muscle is however supplied by the glossopharyngeal nerve (IX) and vagus nerve. This muscle fibre composition of the tongue differs from those of limb, orofacial and masticatory muscles, probably reflecting genotypic as well as. The glossopharyngeal nerve supplies motor fibers to the parotid salivary gland and muscles in the pharynx (throat), larynx (voice box), and soft palate.
The soft palate is composed entirely of various muscle fibers, meaning it doesn't have any bony structure.
The musculature is comprised of five main structures including the musculus uvulae, the tensor veli palatini, the levator veli palatini, the Muscles of the Tongue
When alpha motor neurons die, the muscle fibers that they innervate become deprived of necessary trophic factors and eventually the muscle itself It is characterized by involuntary movements of the tongue, face, arms, lips, and other body parts. Of these, four extrinsic muscle sets (connecting the tongue to the surrounding bones) move the tongue in virtually any direction, with fine shape If the motor nerve supplying the muscle fibers of a muscle, the lower motor neuron (LMN), is severed so that the muscle is deprived of innervation. Upper fibres: tip of the tongue.
