Arteriovenous anastomosis (Sucquet-Hoyer corpuscle) in dermis

Title: Arteriovenous anastomosis (Sucquet-Hoyer corpuscle) in dermis
Description:
(A): Fingertip, Indian ink perfusion-eosin (black-white print), human. The ink perfusion displays the vascularization
pattern as well their anastomoses (so-called Sucquet-Hoyer corpuscles) (left area) in the dermis of the finger.
(B): Skin of finger, stain hematoylin-eosin, human. (1) Lumen of Sucquet-Hoyer canal with epitheloid muscular cells.
(2) Longitudinal section of arteriole.
Background: Arteriolovenular anastomosis forms a thin nodular focus (glomus) in a.o. pads of fingers, toes, ears, feet.
The afferent arteriole becomes devoid of the internal elastic membrane, develops a thick epitheloid muscular wall around
a small lumen and is connected to short thin-walled veins. Innervation occurs by sympathetic, myelinated nerves.
Glomera cutanea in stratum reticulare are also called Sucquet-Hoyer corpuscles (about 150-200 micrometer).
The glomus functions as a shunt-or bypass-regulating mechanism in the flow of blood, indirect control of blood pressure,
and temperature and conservation of heat.
