  2. Perlia's nucleus - Wikipedia

    en.wikipedia.org/wiki/Perlia's_nucleus

    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.

  3. Edinger–Westphal nucleus - Wikipedia

    en.wikipedia.org/wiki/Edinger–Westphal_nucleus

    The Edinger–Westphal nucleus refers to the adjacent population of non-preganglionic neurons that do not project to the ciliary ganglion, but rather project to the spinal cord, dorsal raphe nucleus, lateral septal nuclei, lateral hypothalamic area and the central nucleus of the amygdala, among other regions.

  4. Head and neck anatomy - Wikipedia

    en.wikipedia.org/wiki/Head_and_neck_anatomy

    The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine.

  5. Diagnosis of myocardial infarction - Wikipedia

    en.wikipedia.org/wiki/Diagnosis_of_myocardial...

    The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period. Because these enzyme levels are not elevated immediately following a heart attack, patients ...

  6. Zona incerta - Wikipedia

    en.wikipedia.org/wiki/Zona_incerta

    The zona incerta receives pain input through the spinothalamic tract and this has been shown to control the activity of the pain transmission pathway in the posterior thalamus. [15] Electrical or chemical stimulation of the zona incerta creates limbic-related movements, such as those associated with defense orientation and copulation. [28]

  7. Headache - Wikipedia

    en.wikipedia.org/wiki/Headache

    Cardiac cephalgia [93] is a rare type of headache occurring during myocardial infarction, characterized by sudden, severe head pain that typically develops during or immediately following a heart attack. The pain is usually located in the occipital or frontal regions and can be accompanied by other cardiac symptoms like chest pain, shortness of ...

  8. Cardiac stress test - Wikipedia

    en.wikipedia.org/wiki/Cardiac_stress_test

    By showing the relative amounts of radioisotope within the heart muscle, the nuclear stress tests more accurately identify regional areas of reduced blood flow. [ 12 ] Stress and potential cardiac damage from exercise during the test is a problem in patients with ECG abnormalities at rest or in patients with severe motor disability.

  9. Nucleus accumbens - Wikipedia

    en.wikipedia.org/wiki/Nucleus_accumbens

    The nucleus accumbens (NAc or NAcc; also known as the accumbens nucleus, or formerly as the nucleus accumbens septi, Latin for 'nucleus adjacent to the septum') is a region in the basal forebrain rostral to the preoptic area of the hypothalamus. [1] The nucleus accumbens and the olfactory tubercle collectively form the ventral striatum.
