  2. Nervous tissue - Wikipedia

    en.wikipedia.org/wiki/Nervous_tissue

    Nervous tissue, also called neural tissue, is the main tissue component of the nervous system.The nervous system regulates and controls body functions and activity. It consists of two parts: the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the branching peripheral nerves.

  3. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system. The brain integrates the instructions sent to the rest of the body. The cerebrum, the largest part of the human brain, consists of two cerebral hemispheres.

  4. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. [1]

    The central nervous system is responsible for controlling the body's movements, but it has been understandably hard for scientists to see the network in action until now. For the first time, a ...

  6. 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.

  7. Spinal cord - Wikipedia

    en.wikipedia.org/wiki/Spinal_cord

    The spinal cord (and brain) are protected by three layers of tissue or membranes called meninges, that surround the canal. The dura mater is the outermost layer, and it forms a tough protective coating. Between the dura mater and the surrounding bone of the vertebrae is a space called the epidural space.

  8. Brain cell - Wikipedia

    en.wikipedia.org/wiki/Brain_cell

    Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges, blood vessels, and ducts. The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells, also known as neuroglia. [1]

  9. 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.
