  2. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    The enteric nervous system functions to control the gastrointestinal system. Nerves that exit from the brain are called cranial nerves while those exiting from the spinal cord are called spinal nerves. The nervous system consists of nervous tissue which, at a cellular level, is defined by the presence of a special type of cell, called the ...

  3. Outline of the human nervous system - Wikipedia

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

    The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. 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 ...

  4. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    The human brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous ...

  5. Brain - Wikipedia

    en.wikipedia.org/wiki/Brain

    The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction.

  6. Biological system - Wikipedia

    The lymphatic system includes functions including immune responses and development of antibodies. Immune system: protects the organism from foreign bodies. Nervous system: collecting, transferring and processing information with brain, spinal cord, peripheral nervous system and sense organs.

  7. Nerve net - Wikipedia

    en.wikipedia.org/wiki/Nerve_net

    The nerve net is the simplest form of a nervous system found in multicellular organisms. Unlike central nervous systems, where neurons are typically grouped together, neurons found in nerve nets are spread apart. This nervous system allows cnidarians to respond to physical contact. They can detect food and other chemicals in a rudimentary way.

  8. 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 and spinal cord.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.

  9. Development of the nervous system in humans - Wikipedia

    en.wikipedia.org/wiki/Development_of_the_nervous...

    The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
