What does the tongue do in the nervous system?
Muscles of the tongue are innervated by the hypoglossal nerve (the twelfth cranial nerve, or CN XII). Touch sensation from the anterior two-thirds of the tongue is carried by the trigeminal nerve (CN V), and from the posterior one-third by the glossopharyngeal nerve (CN IX). Taste sensation from the anterior two-thirds of the tongue is from the facial nerve (CN VII), and from the posterior one-third via the glossopharyngeal nerve.

Nerve that passes through the internal acoustic meatus?
The facial nerve (cranial nerve VII) passes through the internal acoustic meatus. It carries motor fibers to the muscles of facial expression and also carries taste sensations from the anterior two-thirds of the tongue.
Which taste sensations could be lost after damage to the facial nerve?
Loss of taste sensations that could result from damage to the facial nerve include the inability to taste sweetness on the anterior two-thirds of the tongue due to dysfunction of the chorda tympani branch of the facial nerve, which carries taste information. This can lead to a reduced ability to detect sweet flavors on that part of the tongue.
What nerve sends messages to the brain from the tongue?
The "Lingual Nerve"The lingual nerve is a branch of the mandibular nerve (CN V3), itself a branch of the trigeminal nerve, which supplies sensory innervation to the tongue. It also carries fibers from the facial nerve, which return taste information from the anterior two thirds of the tongue.Source:- http://en.wikipedia.org/wiki/Lingual_nerve
Why tongue is attached anterior?
The tongue is attached anteriorly to the floor of the mouth and the mandible to provide stability and support for its various functions, such as speaking, swallowing, and tasting. This anterior attachment allows for a greater range of motion and control as it moves to manipulate food and produce sounds. Additionally, the tongue's structure and muscle arrangement enable it to effectively assist in the processes of digestion and communication.
What areas do the submandibular lymph nodes drain from?
Lower face and anterior two thirds of the tongue.
Which one of the following nerves serves the anterior tongue's?
The chorda tympani nerve, a branch of the facial nerve, serves the anterior two-thirds of the tongue for taste sensation.
What is Nerve supply of tip of the tongue?
The tip of the tongue is supplied by the lingual nerve, a branch of the mandibular division of the trigeminal nerve (CN V3). It provides sensory innervation to the anterior two-thirds of the tongue, including the tip.
Two cranial nerves involved in taste are?
facial nerve`s branch - Chorda tympani provides parasympathetic innervation to submandibular gland and sublingual gland and special sensory taste fibers for the anterior 2/3 of the tongue glossopharyngeal nerve whitch receives special sensory fibers (taste) from the posterior one-third of the tongue

What is cranial nerve 7?
Cranial nerve 7 is also referred to as the facial nerve. It has both sensory and motor components. Its sensory portion is responsible for taste on the anterior two thirds of the tongue as well as sensation for a small patch of skin by the ear. Its motor component is responsible for innervating the muscles of facial expression.
Explain How the muscles of the tongue and anterior neck are named?
The tongue and the anterior neck muscles were named from Latin roots. This is the case with much of the human anatomy.
The --- is located in the lower anterior floor of the mouth?
tongue
Which nerve affects your sense of taste and facial expressions?
The facial nerve (cranial nerve VII) affects your sense of taste for the anterior two-thirds of the tongue and is responsible for controlling facial expressions through its motor functions.
What connects the anterior portion of the tongue to the underlying epithelium?
The anterior portion of the tongue is connected to the underlying epithelium by a layer of specialized connective tissue called the lamina propria. This layer helps support the taste buds and allows for movements of the tongue during speech and eating.
