Ultrastructural Study of the Outer Cortex, Deep Cortex and Medulla of Mesenteric Lymph Node in Adult Goats

A mesenteric lymph node in the sub pyloric region which is the longest among all mesenteric lymph nodes in adult goats was identified for study under the scanning electron microscope.

The outer cortical, deep cortical and medullary parenchyma of the collected lymph nodes was thoroughly screened under VEGA3 TESCAN. The outer cortical parenchyma revealed T lymphocytes, B lymphocytes, sinus lining cells (SLC) and sinus reticular cells (SRC) at a magnification of 9600x. The deep cortical parenchyma revealed reticular cells, T lymphocytes and Interdigitating cells (IDC) at 8000x magnification.

The medullary parenchyma revealed T lymphocytes, B lymphocytes, sinus lining cells (SLC), fibrous reticular cells (FRC) and medullary sinuses at a magnification of 8500x. Plasma cells and lymphocytes also remained in the sinus. The morphology and relations of the cells observed were recorded.
