PPT-The anterior pituitary comprises primarily glandular

tissuewhile the posterior pituitary is of neural origin There is a close relation between the neural and the endocrine systems which is most obvious in the interaction between the hypothalamus and the two lobes of the pituitary gland. Glandular fever Glandular fever (infective mononucleosis) is a viral infection commonly occurring in young people. Causes A virus called ‘epstein barr’ causes glandular fever.
