Are adenohypophysis cells and other related secretory cells (such as gonadotroph) neurons or are they different kinds of endocrine cells?
I often read "gonadotroph neurons" but I also saw a review (see underneath) that clearly mention that "gonadotroph are not neurons" so I am trying to clear my mind on it.
Thank you for your help !

Edit: thank you for your answer. I was confused about gonadotroph (cells secreting LH and FSH from the adenohypophysis) and gonadotropin-releasing neurons (releasing GnRH) which soma are in the hypothalamus but they project to the adenohypophysis.
Sheikh Mohd Saleem, I understand cells exhibiting axons and dendrites that could project in various areas and that are excitable (having a resting potential, exhibiting action potentials etc)
Cells forming glands within the brain are neuroendocrine cells. They are not Neurons. On staining, they take acidophilic or basophilic stain.
Anterior and middle lobes of hypophisis are called adenohypophisis and posterior lobe is called neuro hypophisis.
Hi.
The anterior pituitary gland is called the adenohypophysis and has an epithelial origin, while the posterior pituitary gland is called the neurohypophysis and originates from the hypothalamus(neural ectoderm). Hormone-secreting cells in the anterior pituitary gland, unlike the posterior pituitary gland, do not appear to be neurons.
