<span>Neuroendocrine cells of the hypothalamus release releasing hormones into the bloodstream.</span>
Releasing or hypothalamic hormones have a stimulatory or inhibitory effect on the release of the pituary hormones. The main hormones are:
<span><span>· </span>Gonadotropin-releasing hormone (GnRH) stimulates the pituitary to release gonadotropin.
</span> <span><span>· </span>Thyrotropin-releasing hormone (TRH) stimulates the pituitary to release thyrotropin.</span>
<span><span>· </span>Growth hormone–releasing hormone (GHRH) stimulates the pituitary to release somatotropin.
</span> <span><span>· </span>Corticotropin-releasing hormone (CRH) stimulates the pituitary to release corticotropin.</span>
<span><span>· </span>Somatostatin which inhibit the release of somatotropin from pituitary and inhibits the release of some gastrointestinal hormones.</span>
Answer: Consumers.
Explanation: I don't like cockroaches your lucky I even looked at your question let alone answered it.
Answer:
The pollen grain is creating a tube down the style of the flower. <u>It is necessary as that is how the pollen is able to travel down the style into the ovary where the baby seed is located. This is how the seed is fertilized, and is ready for reproduction.</u>
Explanation:
The myelin sheath, lipoprotein structure deposited around axons selected in inner nodules, interrupted periodically by Ranvier nodules, allows saltatory, rapid and effective conduction in the nervous system of vertebrates. The cells that construct myelin are the oligodendrocyte in the nervous central nervous system (CNS) and the Schwann cells in the peripheral nervous system. An oligonucleotide myelinates one or more axons, while the Schwann always forms a single myelin internodule. The process of myelination begins when a cell-sheath projection involves the axon and a loose spiral shape around it. Over time the formed layers are compacted by the expulsion of the cytoplasm and the formation of a lamellar structure with thick electrodes bands - derived from the apposition of the cytoplasmic phases of the membranes - and fewer electrodes - derived of the external phases of the membranes.
