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 ]
Diagnosis is based on the symptoms. Other conditions that may produce similar symptoms include angina, pericarditis, pleurisy, and chest trauma. [1] Treatment is usually via reassurance, as the pain generally resolves without any specific treatment. Precordial catch syndrome is relatively common, and children between the ages of 6 and 12 are ...
Among women who experience a heart attack, many do not have any prior chest pain. [19] Due to alterations in sensory pathways, diabetic and elderly individuals also may present without any chest pain and may have atypical symptoms similar to those seen in women. [8] This type of ischemia is also known as silent ischemia. [21] [22] [23] [24]
However, women may have longer and more severe cluster headaches. [11] The onset of an attack is rapid and typically without an aura. Preliminary sensations of pain in the general area of attack, referred to as "shadows", may signal an imminent cluster headache, or these symptoms may linger after an attack has passed, or between attacks. [12]
Symptoms of postperfusion syndrome are subtle and include defects associated with attention, concentration, short-term memory, fine motor function, and speed of mental and motor responses. [1] Studies have shown a high incidence of neurocognitive deficit soon after surgery, but the deficits are often transient with no permanent neurological ...
An upper motor neuron lesion (also known as pyramidal insufficiency) Is an injury or abnormality that occurs in the neural pathway above the anterior horn cell of the spinal cord or motor nuclei of the cranial nerves.
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.
