The nervous system is composed of neurons and glial cells. Neurons are the excitable cells that carry and process information, whereas the glial cells are the helper cells that protect and support the functions of neurons. The nervous system has two primary components: ...
The Cerebrum:This makes up the majority of the brain and is supported by the brain stem. It is divided into two hemispheres, with each hemisphere controlling the activities of the side of the body opposite that hemisphere. The hemispheres are further divided into the frontal lobe, temporal lobe...
Parts of the Nervous System The vertebrate nervous system is divided into two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain, spinal cord, and retina—the sensory tissue of the visual system. The PNS contains the sensory rece...
In our results, the patients were divided into three groups: PNS (49), AS (34), and PVS (106). No differences were found preoperatively. Intraoperatively, PNS had the shortest operative time and lowest estimated blood loss, and it is the only outpatient procedure. However, it had the ...
The human nervous system, consisting of neurons and support cells, can be divided into the CNS, or central nervous system (which is the brain and spinal cord) and the PNS, or peripheral nervous system (which is everything else). Each has clusters of cell
Because of its direct effect on heart rate, blood pressure, breathing rate, etc., the ANS plays a significant role in the fight-or-flight response. It is further divided into two subsystems, the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). ...
Generally speaking, NP can be subdivided into three categories: sympathetically mediated pain, peripheral NP pain, and central pain. Sympathetically mediated pain arises in a PNS tissue, but is associated with autonomic changes (formerly known as reflex sympathetic dystrophy). Per...
What is heart rate variability (HRV) and why it matters? HRV describes the variations between consecutive inter-beat-intervals or IBIs.
The cell is the smallest unit of life. Cells can be specialized for several different functions as complex organisms consist of various processes throughout their body.Answer and Explanation: The cell surface modification that is made of microtubules is cilia. Cilia are found on various cells, ...
diameter of the fiber is less than 2 mm and the conduction velocity is 2 m/s or less. Non-myelinated C fibers are also heterogeneous. C fiber afferents can be divided into two classes based on their response to mechanical stimuli.
