Smooth muscle distribution in the capsule and trabeculae of the caprine superficial cervical lymph node.

This study centers around the dichotomy found in the literature concerning the presence of smooth muscle cells in the trabeculae and capsule of lymph nodes. Various superficial lymph nodes (mammary, mandibular, popliteal, subiliac, and superficial cervical) of the goat were collected and examined by light and electron microscopy. Smooth muscle cells were demonstrated in the capsule and trabeculae of lymph nodes independent of the blood and lymph vessels.
