  2. ANFO - Wikipedia

    en.wikipedia.org/wiki/ANFO

    ANFO (/ ˈ æ n f oʊ / AN-foh) [1] (or AN/FO, for ammonium nitrate/fuel oil) is a widely used bulk industrial high explosive. It consists of 94% porous prilled ammonium nitrate (NH 4 NO 3 ) (AN), which acts as the oxidizing agent and absorbent for the fuel, and 6% number 2 fuel oil (FO). [ 2 ]

  3. Autonomic nervous system - Wikipedia

    en.wikipedia.org/wiki/Autonomic_nervous_system

    Autonomic nervous system, showing splanchnic nerves in middle, and the vagus nerve as "X" in blue. The heart and organs below in list to right are regarded as viscera. The autonomic nervous system has been classically divided into the sympathetic nervous system and parasympathetic nervous system only (i.e., exclusively motor).

  4. Subfornical organ - Wikipedia

    en.wikipedia.org/wiki/Subfornical_organ

    The impact of the SFO on the cardiovascular system is mostly mediated through its influence on fluid balance. [1] The SFO plays a role in vasopressin regulation. Vasopressin is a hormone that, when bound to receptors in the kidneys, increases water retention by decreasing the amount of fluid transferred from blood to urine by the kidneys.

  5. 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 ...

  6. Cerebral autoregulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_autoregulation

    Cerebral autoregulation is a process in mammals that aims to maintain adequate and stable cerebral blood flow. While most systems of the body show some degree of autoregulation, [1] the brain is very sensitive to over- and underperfusion. Cerebral autoregulation plays an important role in maintaining an appropriate blood flow to that region.

  7. Neurotransmitter - Wikipedia

    en.wikipedia.org/wiki/Neurotransmitter

    By regulating extracellular neurotransmitter levels, astrocytes help maintain proper synaptic function. This bidirectional communication between astrocytes and neurons add complexity to brain signaling, with implications for brain function and neurological disorders.

  8. Neural coding - Wikipedia

    en.wikipedia.org/wiki/Neural_coding

    The brain must obtain a large quantity of information based on a relatively short neural response. Additionally, if low firing rates on the order of ten spikes per second must be distinguished from arbitrarily close rate coding for different stimuli, then a neuron trying to discriminate these two stimuli may need to wait for a second or more to ...

  9. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    The head segment contains the brain, also known as the supraesophageal ganglion. In the insect nervous system, the brain is anatomically divided into the protocerebrum, deutocerebrum, and tritocerebrum. Immediately behind the brain is the subesophageal ganglion, which is composed of three pairs of
