  2. Pons - Wikipedia

    en.wikipedia.org/wiki/Pons

    Cross-section of lower pons, axons shown in blue, grey matter in light grey. Anterior is down and posterior is up. A number of cranial nerve nuclei are present in the pons: mid-pons: the principal sensory nucleus of the trigeminal nerve (V) mid-pons: the motor nucleus for the trigeminal nerve (V) lower down in the pons: abducens nucleus (VI)

  3. Pontine tegmentum - Wikipedia

    en.wikipedia.org/wiki/Pontine_tegmentum

    The pontine nuclei are located within the basilar pons. Also nearby are the raphe nuclei and the locus coeruleus, nuclei of cranial nerves 9-12, and the dorsal respiratory group, which are located further caudally in the brainstem. The dorsal respiratory group are connected to the pneumotaxic and apneustic centres of the pontine tegmentum.

  4. Pontine nuclei - Wikipedia

    en.wikipedia.org/wiki/Pontine_nuclei

    Pontocerebellar fibers are the sole efferent pathway of the pontine nuclei. The fibers mostly decussate within the pons to pass through the (contralateral) middle cerebellar peduncle to terminate in the contralateral cerebellum as mossy fibers; they form terminal synapses in the cerebellar cortex, but also issue collaterals to the cerebellar nuclei.

  5. Table of cranial nerves - Wikipedia

    en.wikipedia.org/wiki/Table_of_cranial_nerves

    A major function: controls muscles for voice and resonance and the soft palate. Symptoms of damage: dysphagia (swallowing problems), velopharyngeal insufficiency. This nerve is involved (together with nerve IX) in the pharyngeal reflex or gag reflex. XI Accessory. Sometimes: cranial accessory, spinal accessory. Mainly motor Cranial and Spinal Roots

  6. Cranial nerves - Wikipedia

    en.wikipedia.org/wiki/Cranial_nerves

    Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck , including the special senses of vision , taste , smell , and hearing .

  7. Abducens nerve - Wikipedia

    en.wikipedia.org/wiki/Abducens_nerve

    Axial section of the Brainstem (Pons) at the level of the Facial Colliculus. The abducens nucleus is located in the pons, on the floor of the fourth ventricle, at the level of the facial colliculus. Axons from the facial nerve loop around the abducens nucleus, creating a slight bulge (the facial colliculus) that is visible on the dorsal surface ...

  8. Trigeminal nerve nuclei - Wikipedia

    en.wikipedia.org/wiki/Trigeminal_nerve_nuclei

    The sensory trigeminal nerve nuclei are the largest of the cranial nerve nuclei, and extend through the whole of the midbrain, pons and medulla, and into the upper cervical spinal cord. The nucleus is divided into three parts, from rostral to caudal (top to bottom in humans): The mesencephalic nucleus; The principal sensory nucleus

  9. Salivatory nuclei - Wikipedia

    en.wikipedia.org/wiki/Salivatory_nuclei

    The salivatory nuclei are two general visceral efferent nuclei located in the caudal pons, dorsal and lateral to the facial nucleus. Their neurons give rise to preganglionic parasympathetic nerve fibers in the control of salivation. [1] [2] The superior salivatory nucleus supplies fibers to the intermediate nerve (part of the facial nerve (CN VII).
