An Anatomical Study of the Facial Artery [PDF]

open access: yesInternational Journal of Morphology, 2019
SUMMARY: The facial artery (a branch of the external carotid artery) is the main artery of the face. It gives rise to seven branches viz. inferior labial, superior labial, inferior alar, superior alar, lateral nasal and angular arteries, which are variable. This study included a dissection of twenty embalmed adult cadaveric head and neck specimens. The

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...
