  2. Haemodynamic response - Wikipedia

    en.wikipedia.org/wiki/Haemodynamic_response

    Vasoactive mediators, such as nitric oxide and prostacyclin, along with overexpression of vasoconstrictors not only affect vascular tone but also promote vascular remodeling. PAH deals with increase blood pressure in pulmonary arteries, which leads to shortness of breath, dizziness, fainting, rarely hemoptysis , and many other symptoms.

  3. Vasoconstriction - Wikipedia

    en.wikipedia.org/wiki/Vasoconstriction

    Moreover, impaired blood flow resulting from abnormal vasoconstriction may contribute to tissue ischemia, which can be observed in conditions like Raynaud's disease. Understanding the pathology of vasoconstriction is crucial for developing targeted therapeutic strategies to manage conditions associated with abnormal vascular tone. [17]

  4. Basal body - Wikipedia

    en.wikipedia.org/wiki/Basal_body

    Basal bodies originate from and have a substructure similar to that of centrioles, with nine peripheral microtubule triplets (see structure at bottom center of image). A basal body (synonymous with basal granule , kinetosome , and in older cytological literature with blepharoplast ) is a protein structure found at the base of a eukaryotic ...

  5. Myogenic mechanism - Wikipedia

    en.wikipedia.org/wiki/Myogenic_mechanism

    Bayliss effect or Bayliss myogenic response is a special manifestation of the myogenic tone in the vasculature. [3] [4] The Bayliss effect in vascular smooth muscles cells is a response to stretch. This is especially relevant in arterioles of the body. When blood pressure is increased in the blood vessels and the blood vessels distend, they ...

  7. Vagal tone - Wikipedia

    en.wikipedia.org/wiki/Vagal_tone

    Vagal tone research has the potential to offer insight into social behavior, social interactions, and human psychology. Much of this work has been focused on newborns and children . [ 26 ] Baseline vagal tone can be used either as a potential predictor of behavior or as a signal of mental health (particularly emotion regulation , anxiety , and ...

  8. Neurovascular unit - Wikipedia

    en.wikipedia.org/wiki/Neurovascular_unit

    Vascular risk factors can result in dysregulation of the neurovascular unit and hypoxia. Destruction of the organization of the blood–brain barrier, decreased cerebral blood flow, and the establishment of an inflammatory context often result in neuronal damage since these factors promote the aggregation of β-amyloid peptide in the brain.

  9. Basal cell - Wikipedia

    en.wikipedia.org/wiki/Basal_cell

    A basal cell is a general cell type that is present in many forms of epithelial tissue throughout the body. Basal cells are located between the basement membrane and the remainder of the epithelium, effectively functioning as an anchor for the epithelial layer and an important mechanism in the maintenance of intraorgan homeostasis.
