Cells Interacting:

Astrocytoma in its cancerous form is a situation in which a malignant tumor starts in Astrocyte cells, which have the purpose of protecting nerve cells. As the tumor grows invasively into these cells, it presses on the nerve cells and other parts of the brain. Cancerous astrocytoma will grow very quickly, spreading into other sections of brain tissue. As it does this, it will start to push on the brain itself and stop it from functioning properly. ….

Function: The astrocyte cell is a type of glial cell, very common in the Central nervous system, and present for the purpose of providing structure and insulation for neurons. The astrocyte itself has the function of keeping nerve cells in place and protecting them, as

Astrocytoma is classified as a type of glioma, which is a tumors forming in glial tissue in the Central Nervous System. Astrocytomas specifically form in cerebrum, the cerebellum, the brainstem, the hypothalamus, the visual pathway, and occasionally the spinal cord. Astrocytoma comes in two forms, benign and malignant, with the malignant being the more serious of the two and spreading to other parts of the brain, while a benign case of astrocytoma would not grow to parts of the brain other than where it started. In its cancerous form, the tumor starts out in the astrocyte but continues to grow, eventually growing out of the original cells and into other tissue, which will push against the brain and stop it from functioning in the fashion which it is supposed …show more content…
this only changes concentration of sodium within a few molecules of the cell membrane. doesn’t have significant impact after action potential, to restore positive charge, potassium leaks out...not enough to change potassium concentration outside the cell except for in immediate vicinity of the membrane itself when there are millions of neurons firing frequently, electrolytes can become imbalanced, and there can be too much potassium in the membrane astrocytes cleanup by soaking up the extra potassium ions potassium ions can spread out through network so they can be dissipated, and if there is too much potassium for the network, it can be dumped in capillary network since astrocyte is connected to that

    Ammonia has direct access to the circulatory system and it is able to reach the brain. Only a small amount can leak through the blood-brain barrier , but if the levels of NH3 in blood are very high, then more of it will enter. An excess of ammonia is toxic and causes neurological disorders and damages, leading to a condition called Encephalopathy. As listed in the case, possible symptoms are disorientation, lethargy, slurred speech, behavior change and also motor skills impairments such as Asterixis and hyperreflexia. Brain hyperammonemia initiates a series of reactions with major consequences: swelling of astrocytes (glial cells) with related communication problems between neurons, and disruption of cerebral metabolism and energy production.…
