Perlia's nucleus, also known as nucleus of Perlia and abbreviated as NP, is a spindle-shaped nucleus located in the mesencephalon, a subdivision of the Edinger-Westphal nucleus [1] [2] situated between the right and left oculomotor nuclei. It is implicated in parasympathetic oculomotor functions, possibly including input to the iris and ciliary.
The Edinger–Westphal nucleus also called the accessory or visceral oculomotor nerve, is one of the two nuclei of the oculomotor nerve (CN III) located in the midbrain. [ 1 ] [ 2 ] [ 3 ] It receives afferents from both pretectal nuclei (which have in turn received afferents from the optic tract ). [ 4 ]
Perlia's nucleus (Nucleus of Perlia) Piotrowski signs: Yes signs of organic brain damage Brain Overclaim Syndrome: Corpora bigemina: Embryology of superior and inferior colliculi Shooting pain: Take a look at Types of pain, ie dull pain and sharp pain.
The sensory decussation or decussation of the lemnisci is a decussation (a crossing over) of axons from the gracile nucleus and cuneate nucleus, known together as the dorsal column nuclei. The dorsal column nuclei are responsible for fine touch, vibration, proprioception and two-point discrimination.
The subparabrachial nucleus (also known as the Kölliker-Fuse nucleus, or diffuse reticular nucleus) regulates the breathing rate. It receives signals from the caudal , cardio-respiratory part of the solitary nucleus and sends signals to the lower medulla oblongata , the spinal cord , the amygdala and the lateral hypothalamus .
Perlia's nucleus; Principal sensory nucleus of trigeminal nerve; S. Salivatory nuclei; Solitary nucleus; Spinal accessory nucleus; Spinal trigeminal nucleus;
The medial lemniscus carries axons from most of the body and terminates by synapsing with third-order neurons in the ventral posterolateral nucleus of the thalamus. [3] at the level of the mamillary bodies. Sensory axons transmitting information from the head and neck via the trigeminal nerve synapse at the ventral posteromedial nucleus of the ...
The ventral posterior nucleus is divided into: Ventral posterolateral nucleus, which receives sensory information from the body via the medial lemniscus, and spinothalamic tracts. Ventral posteromedial nucleus, which receives sensory information from the head and face via the trigeminal nerve.
