Cranial nerve 12: hypoglossal nerve: Anatomy and function – Kenhub
3 nov. 2023The hypoglossal nucleus is a thin and long nucleus lies in the ventral portion of the medulla, near the midline. Its rostral portion belongs to an area called the hypoglossal trigone . The neurons of this nucleus are multipolar and they send efferent fibers that extend anteriorly and laterally.
Spinal Nerves
There are 31 bilateral pairs of spinal nerves, named from the vertebra they correspond to. For the most part, the spinal nerves exit the vertebral canal through the intervertebral foramen below their corresponding vertebra. Therefore, there are 12 pairs of thoracic spinal nerves, 5 pairs of lumbar spinal nerves, 5 pairs of sacral spinal nerves, and a coccygeal nerve.
Vagus Nerve
The vagus nerve, or the 10th cranial nerve (CN X), is primarily associated with the parasympathetic division of the autonomic nervous system, however, it also has some sympathetic influence through peripheral chemoreceptors.The vagus nerve is a mixed nerve, as it contains both afferent (sensory) and efferent (motor) fibers.This means it is responsible for not only carrying motor signals to the …
Trigeminal Nerve Cn V
The principal regulator of the sensory modalities of the head is the trigeminal nerve.This is the fifth of twelve pairs of cranial nerves that are responsible for transmitting numerous motor, sensory, and autonomous stimuli to structures of the head and neck.. While the trigeminal nerve (CN V) is largely a sensory nerve, it also mingles in the realm of motor supply.
Nucleus
Descending from the fovea, there is a sulcus that runs obliquely towards the middle line. That sulcus divides the medial eminence into two triangles – the hypoglossal trigone (which houses the cranial nerve nuclei called hypoglossal nuclei), medially; and the vagal trigone (housing the vagal nuclei), laterally
Glossopharyngeal Nerve
Nucleus ambiguus. This is a group of motor neurons located deep in the medullary reticular formation.Besides the glossopharyngeal nerve, this nucleus is common for the vagus nerve and the accessory nerve.. This nucleus contains neurons that provide motor innervation to several muscles of the soft palate, the pharynx, the larynx and the upper part of the esophagus.
Accessory Nerve
Nuclei of the accessory nerve. Motor neurons from each of the five upper cervical segments give rise to neuronal rootlets that protrude from the anterior surface of the spinal cord. This spinal accessory nucleus (also called the accessory nucleus proper) rarely extends beyond C5 but has been observed as low as C7. The rootlets eventually coalesce to form a solitary nerve fiber known as the …

The hypoglossal nerve, also known as the twelfth cranial nerve, cranial nerve XII, or simply CN XII, is a cranial nerve that innervates all the extrinsic and intrinsic muscles of the tongue except for the palatoglossus, which is innervated by the vagus nerve. [a] CN XII is a nerve with a sole motor function.
