WebSep 24, 2024 · Myogenic vasoconstriction is an autoregulatory function of small arteries. Recently, G-protein-coupled receptors have been involved in myogenic vasoconstriction, but the downstream signalling mechanisms and the in-vivo-function of this myogenic autoregulation are poorly understood.

Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture, the passageway from the lower neck to the armpit, also known as the thoracic outlet. There are three main types: neurogenic, venous, and arterial.

After birth, the satellite cell population accounts for ∼30% of sublaminar muscle nuclei in neonatal hindlimb skeletal muscle ( 12 ). WebIn myogenic ptosis, the levator muscle is weakened due to a systemic disorder that causes muscle weakness. These conditions may include chronic progressive external ophthalmoplegia and types of muscular dystrophy.
