Loose diffuse
Definition
Term
dense diffuse
Definition
primary nodule
secondary nodule with germinal center
Term
palatine tonsil
Definition
-covered by stratified squamous epithelium (lingual too)
-crypts (palatine)

cortex within trabeculae has nodes
medulla contains medullary cords
Term
Lymph node sinuses
Definition
subscapular, peritrabecular, medullary
Term
Afferent lymphatic vessels
Definition
enter in subscapular sinus --> peritrabecular --> medullary sinus
some goes through slow route --> through medullary sinus
