DEFINITION:
- vas sinusoideum
-
Sinusoid: a form of terminal blood channel consisting of a large, irregular anastomosing vessel, having a lining of reticuloendothelium but little or no adventitia; sinusoids are found in the liver, adrenals, heart, parathyroid, carotid gland, spleen, hemolymph glands, and pancreas. Those in the anterior pituitary gland, adrenal cortex, and islets of Langerhans have a continuous basal lamina and a thin endothelium penetrated by pores closed by thin diaphragms (fenestrated sinusoids); in many mammals the endothelial cells lining those of the liver meet and overlap in some areas, while there are gaps between the cells in other areas (discontinuous sinusoids). Called also "sinusoidal capillary."
