Nerves
...  Nerves are an enclosed bundle of peripheral axons. They are cable-like in appearance and they provide the pathway for nerve impulses that are transmitted along the axons. Nerves are found in the Peripheral Nervous System. All nerves have a cordlike structure and contain many axons. Each of these axons are surrounded the endoneurium, these are layers of connective tissues. The axons, in turn,  ...

Spinal Nerves
...  nervous system is the primary control system in the body. It is divided into the central nervous system and the Peripheral Nervous System. The spinal nerves are parts of the Peripheral Nervous System. They receive inputs from the different sensory organs in the body and deliver the information to the central nervous system for processing. Number and Nomenclature The human body has 31 spinal  ...

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  ...

Neurotransmitters
...  manner in the spinal cord and enters the neuron, resulting to Inhibitory Postsynaptic Potential or IPSP. Endorphins You can find these neurotransmitters in both the central nervous system and the Peripheral Nervous System. It is also known as the endogenous morphine because it has almost the same effect as morphine. Morphine acts as an anesthetic agent and induces euphoria and a false sense  ...

Cervical Nerve Plexus
...  that innervate or send sensory data to the neck, the shoulders and the head. It also 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  ...

Abducens Nerve
...  nervous system is divided into two parts: the central nervous system and the Peripheral Nervous System. The Peripheral Nervous System is further subdivided into the autonomic nervous system and the sensory-somatic nervous system. The sensory-somatic system consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves. The sixth pair among these 12 pairs is the abducens nerves. Anatomy  ...

Accessory Nerve
...  of the eleventh pair of the twelve pairs of cranial nerves. There are twelve cranial nerves found in the sensory-somatic system. The sensory-somatic system forms one of the two subdivisions of the Peripheral Nervous System. The Peripheral Nervous System, together with the central nervous system, comprises the nervous system. Now that we have laid the groundwork, let us look into the accessory  ...

Myelination
...  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 the Peripheral Nervous System. Myelin creates the white matter that could be seen in the brain. It is also responsible for the whitish color of the nerves and the spinal cord. In the peripheral nervous  ...

Neurolgia
...  microglia, ependymal, astrocytes and ganglionic gliocytes. Take a look at the characteristics of each. Neurolemmocytes - It makes up the myelin layers, the ones surrounding the axon cells in the Peripheral Nervous System. Oligodendrocytes - It has the same role with the neurolemmocytes, except for the fact that it works in the central nervous system. Microglia - It aids in the debris  ...
