The hilum of the lymph nodes is the primary point of entry for.

The lymph nodes of the head and neck can be divided into two groups. Together the trabeculae and reticular fibers form a support network for immune cells that are packed in like grapes. The superficial lymph nodes of the head and neck receive lymph from the scalp face and neck.

Stretched between the trabeculae is a meshwork of thinner walls called reticular fibers. Generallyoval bean shaped structures scattered throughout body along lymphvesselsusually. Anatomy of lymph node 1.
