Nervous Tissue Histology & Glial Cells — Practice

A microbiology resident examines a haematoxylin and eosin stained section of an endocrine organ. The slide shows a thin connective-tissue capsule, an outer cortex with cells arranged in a superficial thin zone of clusters (zona glomerulosa), a thick middle zone of cells in straight cords (zona fasciculata), and a deeper anastomosing network (zona reticularis), surrounding a central medulla of chromaffin cells.
