Document Summary
Long distance communication: communication between nonadjacent cells is enabled by a number of chemical substances. Neuro-endocrine signaling: nerve cells can be sources of hormones, i. e. the hypothalamus is an important source, posterior pituitary, a neurological extension of hypothalamus, is also an important source of hormones. Thus, the nervous system is responsive to both electrical and hormonal inputs. Anterior pituitary: adrenocorticotrophic hormone (acth, thyroid-stimulating hormone (tsh, luteinizing hormone (lh, follicle-stimulating hormone (fsh, prolactin (prl, growth hormone (gh, melanocyte-stimulating hormone (msh) Autocrine signaling: classical view of endocrinology, endocrine signaling: long distance signaling organ in one part of the. Hormonal signaling body produced a signal that went into the bloodstream and found a target organ elsewhere: however, hormones do short term communication. They can send signals to nearby targets: paracrine signaling: like cell type a stepping outside to talk to its neighbor cell type b.
