    The autonomic nervous system is apart of the nervous system that receives instructions from the brain. It has two parts which are the sympathetic and parasympathetic. The sympathetic nervous system controls the bodes response to a perceived threat and is responsible for the fight, flight or freeze response. Where as the parasympathetic nervous system function is to control the homeostasis and the bodies rest and digest response. The sympathetic nervous system has a thoraco-lumbar outflow from…

    The human body is extremely complex and made up of various systems and organs that must work together. When one part does not function the way it is suppose to, it can slow down the functions of the other parts, which can be detrimental . A quote by Doris Lessing states that when one’s body malfunctions or contains chemical imbalances, “It makes you aware of the knife-edge we live on”. In order for the human body to function correctly, the central nervous system, endocrine, and peripheral…

    (The nervous system Louisa Idzal) The nervous system is all connected because it’s a web of nerve cells and fibers that all send nerve impulses throughout and between body parts. The nervous system is really important because it’s in charge of sending messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the…

    Synapses are the basic functional units in Central Nervous System (CNS). The synapses enable neuron-to-neuron communication via releasing and uptake of neurotransmitters. The synapse formation is modulated by specialized CNS cell type, glia. The glia modulates neuronal function via synapse formation, modification and elimination and, the glia even affects reorganization of neuronal circuit. Understanding cellular and molecular interactions of these glial cells is of great importance because they…

    I believe the first thing your body will do is hear the phone ring, which is a disruption in activity. So, the sympathetic nervous system will kick into alert. The pupil will dilate to allow the person to see more, the heart rate will increase so the blood will be supplied to areas that needs the glucose and use it for energy in case any muscles need to be contracted for moving. Then the person look at the phone after hearing a sound, the cones and rods in the retina will send a signal to the…
