  2. Outline of the human nervous system - Wikipedia

    en.wikipedia.org/wiki/Outline_of_the_human...

    Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body. The human nervous system consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord.

  3. Peripheral nervous system - Wikipedia

    en.wikipedia.org/wiki/Peripheral_nervous_system

    The peripheral nervous system (PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS). The PNS consists of nerves and ganglia , which lie outside the brain and the spinal cord . [ 1 ]

  4. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    The peripheral nervous system (PNS) is a collective term for the nervous system structures that do not lie within the CNS. [17] The large majority of the axon bundles called nerves are considered to belong to the PNS, even when the cell bodies of the neurons to which they belong reside within the brain or spinal cord.

  5. Neuroanatomy - Wikipedia

    en.wikipedia.org/wiki/Neuroanatomy

    The vertebrate nervous system is divided into the central and peripheral nervous systems. The central nervous system (CNS) consists of the brain, retina, and spinal cord, while the peripheral nervous system (PNS) is made up of all the nerves and ganglia (packets of peripheral neurons) outside of the CNS that connect it to the rest of the body ...

  6. Central nervous system - Wikipedia

    en.wikipedia.org/wiki/Central_nervous_system

    The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.

  7. Redlich–Obersteiner's zone - Wikipedia

    en.wikipedia.org/wiki/Redlich–Obersteiner's_Zone

    The Redlich–Obersteiner's zone, also known as the root entry zone, is a boundary between the central nervous system (CNS) and the peripheral nervous system (PNS). [1] The Redlich–Obersteiner's zone is located at the point of entry of either between cranial nerves and the brain or spinal nerves and the spinal cord. This narrow zone is ...

  8. Classification of peripheral nerves - Wikipedia

    en.wikipedia.org/wiki/Classification_of...

    The classification of peripheral nerves in the peripheral nervous system (PNS) groups the nerves into two main groups, the somatic and the autonomic nervous systems. [1] Together, these two systems provide information regarding the location and status of the limbs, organs, and the remainder of the body to the central nervous system (CNS) via ...

  9. Group C nerve fiber - Wikipedia

    en.wikipedia.org/wiki/Group_C_nerve_fiber

    Group C nerve fibers are one of three classes of nerve fiber in the central nervous system (CNS) and peripheral nervous system (PNS). The Group C fibers are unmyelinated and have a small diameter and low conduction velocity, whereas Groups A and B are myelinated.
