Glioblastoma Multiforme
...  loss of sensation (when the parietal lobe is involved) generalized body weakness cognitive impairment loss of vision It rarely happens, but it is possible that GBM will develop in an adult’s brainstem. This will lead to experiencing decreased level of consciousness, one-sided body weakness, and progressive and persistent headaches. Standard GBM Diagnostic Examinations There are several  ...

Nerves
...  based on where they are connected. The two categories are: Spinal nerves that are connected through the spinal column to the spinal cord and Cranial nerves that are directly connected to the brainstem. Spinal nerves are given letter and number designations whereas cranial nerves are assigned roman numerals from 1 to 12. Nerves transmit information through electrochemical impulses or what  ...

Parasympathetic Division
...  are found in preganglionic neurons to form a connection between spinal and cranial nerves, all the way to the terminal ganglia. The preganglions are cell bodies located in the oculomotor nerve, brainstem, vagus nerve, facial nerve, glossopharyngeal nerve, and in the spinal cord. The terminal ganglia are found in the walls of the target organs at the pelvis, thorax and abdomen or in the  ...

Neurotransmitters
...  of neurotransmitter substances are serotonin, glycine, endorphins, gamma amino butyric acid (GABA), acetylcholine, norepinephrine, and dopamine. Serotonin This substance, which is found in the brainstem, the gastrointestinal tract and the platelets, is responsible for sleep induction and good mood. When the concentrations are elevated, it is often associated with delusions and  ...

Cerebrum
...  cerebrum is the largest part of the brain that constitutes the forebrain. It is the part of the brain that is responsible for all the voluntary actions of the body. It is located on top of the brainstem and is considered the most developed part of the brain. The cerebrum is the newest structure in the brain, phylogenetically speaking. This part of the brain is most-developed in mammals among  ...

Diencephalon
...  part of the brain. Even with only the size of an apricot, its function is so enormous that you cannot live normally when it is defective. This part is in the core center of the brain, above the brainstem. The complexity of the structure associates well with its functions. Here are the parts of this tiny tissue. Thalamus The thalamus comprises the upper and majority parts of the  ...

Abducens Nerve
...  Where can you find the abducens nerve? There are two abducens nerves in the body, one for each eye. This pair is the sixth of the cranial nerves and it is composed of motor fibers. It leaves the brainstem at the junction of the medulla and pons. It is located medial to the facial nerve. For it to reach the eye, it runs upward and then bends forward. How does the nerve work? After emerging  ...
