Neuroendocrine cells neurosecretory cells are cells that receive neuronal input neurotransmitters released by nerve cells and, as a consequence of this input, release message molecules hormones to the blood. In this way they bring about an integration between the nervous system and the endocrine system , a process known as neuroendocrine integration. An example of a neuroendocrine cell is the cell of the adrenal medulla innermost part of the adrenal gland which releases adrenalin to the blood. The adrenal medullary cells are controlled by the sympathetic nervous system sympathetic division of the autonomic nervous system . These cells are modified postganglionic neuron s. Autonomic nerve fibers lead directly to them from the central nervous system. The adrenal medullary hormones are kept in vesicles much in the same way neurotransmitters are kept in neuronal vesicles. Hormonal effects can last up to ten times longer than those of neurotransmitters. Sympathetic nerve fiber impulses stimulate the release of adrenal medullary hormones. In this way the sympathetic division of the autonomic nervous system and the medullary secretions function together. The major center of neuroendocrine ... are released directly to the peripheral circulation.

Transarterial chemoembolization TACE , also called hepatic artery chemoembolization HACE , is a technique in which small embosphere s particles designed to block blood vessel s coated with chemotherapeutic drugs are injected directly into an artery supplying a tumor . This leads to two synergistic effects the injected emboli restrict the tumor s arterial blood supply, and the chemotherapeutic agent is delivered directly to the target tissue. As an added benefit, the chemotherapeutic side effects of this treatment are greatly diminished compared to systemic chemotherapy , as the chemotherapeutic agent is locally concentrated in the area of the tumor. TACE is used for several types of hepatic tumors, most notably hepatoblastoma s and neuroendocrine tumor s.
