Peripheral Ganglia
...  Ganglia are a group of cells found in the Peripheral Nervous System or PNS. The PNS is found in the periphery of the Central Nervous System or CNS. This exists outside the spinal cord and the brain and is not enclosed with any protective structure. The peripheral Ganglia have the following characteristics: Major Function The major function of the peripheral Ganglia is to connect the  ...

Parasympathetic Division
...  cannot function properly, though, without these essential related parts. Axons 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  ...

Sympathetic Division
...  the abdominal area. Sometimes, in extreme instances, people are prompted to urinate or defecate because of this. The sympathetic nervous system or division works through both the sympathetic chain Ganglia and the collateral Ganglia, which is responsible for a person’s response to these situations. Because of this, a person who could not ordinarily carry a refrigerator can now carry one  ...

Cerebrum
...  to other regions of the brain. The cerebrum is actually responsible for all the complex behaviours in human beings. The cerebrum is composed of three sub-regions; the cerebral cortex, basal Ganglia and the limbic system. The functions of the cerebrum are outlined in detail below: The cerebrum is primarily responsible for the volitional motor functions of the body. These movements come  ...

Diencephalon
...  Several nuclei make up each of the lobes of the organ. The basis of their naming depends on their position. You can have names such as the medial, lateral or central nuclei. Together with the basal Ganglia and cerebellum, this part of the diencephalon is responsible for the movement coordination of the brain. Hypothalamus The hypothalamus lies just beneath the thalamus. It is the lower part of  ...

Myelination
...  has a myelin coating. However, not all have an adequate amount of it. Myelin supports conduction of the cells. It is known as the white lipid protein that supports myelination of a certain Ganglia. Myelination, on the other hand, is a process in which the neurolemmocyte or oligodendrocyte surrounds a certain part of the axon or dendrite. It occurs both in the central nervous system and  ...

Neurons
...  transport in the cell. The endoplasmic reticulum on the other hand aids the action of the protein synthesis. Cells in the CNS are grouped together, calling it a nuclei, and they are also found in a Ganglia. - Dendrites are the small branches that reach out from the cell. It helps determine which stimuli to respond to (for the cells). It also aids the impulse conduction in the cell body. It is  ...

Parathyroid Glands
...  However, the innervation of the parathyroid glands differ from that of the thyroids. Vagus nerves branch into pharyngeal branches to deliver the neurons to the parathyroids. The cervical sympathetic Ganglia also drive neurons to the parathyroid glands. The parathyroid glands only secrete one hormone - the parathyroid hormone. A hormone called calcitonin that is designed to decrease blood calcium  ...

Thyroid Gland
...  cells are known as parafollicular cells, and they secrete calcitonin and thyrocalcitonin. Innervation to the thyroid gland comes from the postganglionic neurons from the superior and middle cervical Ganglia. Additional innervation is supplied by the second to the seventh segment of the spinal cord with their preganglionic neurons. The thyroid is the gland that produces the hormones thyroxine and  ...
