  2. Cerebrum - Wikipedia

    en.wikipedia.org/wiki/Cerebrum

    In the human brain, the cerebrum is the uppermost region of the central nervous system. The cerebrum develops prenatally from the forebrain (prosencephalon). In mammals, the dorsal telencephalon, or pallium , develops into the cerebral cortex, and the ventral telencephalon, or subpallium , becomes the basal ganglia .

  3. 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 ...

  4. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    The human brain is the central organ of the 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 system ...

  5. Motor system - Wikipedia

    en.wikipedia.org/wiki/Motor_system

    The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement. [ 1 ] [ 2 ] Peripheral structures may include skeletal muscles and neural connections with muscle tissues. [ 2 ]

  6. Cerebrospinal fluid - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid

    The autonomic nervous system influences choroid plexus CSF secretion, with activation of the sympathetic nervous system decreasing secretion and the parasympathetic nervous system increasing it. [3] Changes in the pH of the blood can affect the activity of carbonic anhydrase , and some drugs (such as furosemide , acting on the Na-K-Cl ...

  7. 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.

  8. Nerve - Wikipedia

    en.wikipedia.org/wiki/Nerve

    The nervous system is the part of an animal that coordinates its actions by transmitting signals to and from different parts of its body. [7] In vertebrates it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain, including the brainstem, and spinal cord.

  9. Neuromuscular junction - Wikipedia

    en.wikipedia.org/wiki/Neuromuscular_junction

    In the neuromuscular system, nerves from the central nervous system and the peripheral nervous system are linked and work together with muscles. [3] Synaptic transmission at the neuromuscular junction begins when an action potential reaches the presynaptic terminal of a motor neuron , which activates voltage-gated calcium channels to allow ...
