Baclofen

...  is a generic drug that is used to treat some ill health conditions of the central nervous system. Disorders that are related to spinal cord injuries are treated with this drug. Also, it is helpful for people who are suffering from spastic diplegia (a certain type of cerebral palsy), multiple sclerosis (a chronic disease that inflames the nervous system), amyotrophic lateral sclerosis  ...

Nerves

...  to and from the central nervous system. Nerves can be further categorized 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.  ...

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  ...

Axon

...  axon is a vital part of the motor neuron, which is responsible for conducting action potentials from one part of the spinal cord or brain to another portion. It is an elongated structure extending from the neuron. Without the axon, the neurons will not be able to perform their physiologic functions. These axons come in two types; the axons that render action potentials towards the central  ...

Neurotransmitters

...  and the platelets, is responsible for sleep induction and good mood. When the concentrations are elevated, it is often associated with delusions and schizophrenia. Glycine Glycine is found in the spinal cord and the brain. This acts in an inhibitory manner in the spinal cord and enters the neuron, resulting to Inhibitory Postsynaptic Potential or IPSP. Endorphins You can find these  ...

Cerebrum

...  of human interaction, speech and learning works in humans through the complex processes that occur in these areas. The olfactory, limbic and motor systems send fibres from the cerebrum to the spinal cord and brainstem; the volitive and cognitive systems, in turn, sends fibres from the cerebrum to the thalamus to other regions of the brain. The cerebrum is actually responsible for all the  ...

Cervical Nerve Plexus

...  extends to the pharynx. It is embedded deep in the side of the neck. The cervical nerve plexus is a part of the Peripheral Nervous System or PNS; a part of the nervous system which is outside of the spinal cord and the brain. Ways to care for the cervical nerve plexus The cervical plexus nerves can be injured due to sports, hard manual work or accidents. The compression of the nerves or  ...

Blood Supply to the Brain

...  artery, a component found at the base of the neck. For the blood supply to enter the brain, these arteries pass through the foramen magnum. This is an opening at the base of the skull where the spinal cord merges with the brain region of the medulla oblongata. The arteries are conjoined once they have penetrated the cranium to form the basilar artery. This artery, in turn, serves as the  ...

Medulla Oblongata

...  in the pons. It is also connected posteriorly in the spinal cord. Medulla oblongata is situated at the same level as with foramen magnum. When it is viewed externally, it would look similar to the spinal cord except for the pyramids. On the other hand, the pyramids seen in the spinal cord are elevated elements having a triangular shape. The space near the medulla oblongata is the fourth  ...

Meninges

...  convulsion and the spinal cord’s irregularities. It also consists of a specially modified connective tissue, and is intended to be vascular to support the nourishment of the brain cells, the spinal cord and other parts that surround it. The pia mater also works with the arachnoid to help build one of the components of the ventricles- the roofs. It also contributes to the formation of  ...
