The enteric nervous system (ENS) or intrinsic nervous system is one of the main divisions of theautonomic nervous system (ANS)and consists of a mesh-like system of neurons that governs the function of the gastrointestinal tract.[1] It is capable of acting independently of the sympathetic and ...
The Nervous System - CNS & PNS How does the nervous system function? 點擊卡片即可翻轉 👆 Sensory info travels from spinal cord posteriorly with real-world info Sensory/afferent info used to "make decisions" of how to respond Motor/efferent info descends spinal cord and exits via muscles or ...

Describe the structure and function of the four types of glial cells within the CNS and the two types of glial cells of the PNS. How is an interneuron different from a motor neuron or a sensory neuron? What are the different classes of neurons and their functions? Clas...
CNS function acts as control center for nervous system; processes information; provides short-term control over activities of other systems Peripheral Nervous System Components (PNS) the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body. PNS function ...
What is the difference in function between CNS gray matter and CNS white matter? Where are these tissues located in the brain and spinal cord? What structure is found surrounding axons in both the CNS and the PNS? a. myelin sheath b. neurilemma c. Nodes of Ranvier d. plasma membrane e...
Despite a general lack of stabilising fibrillar collagenous and elastic structures in the CNS/PNS, a sophisticated dynamic extracellular matrix is nevertheless important in tissue form and function. Conclusions: This review provides examples of the sophistication of the CNS/PNS extracellular matrix, ...
To gain insights into the differential responses of CNS and PNS neurons to reduced neurofibromin function, we designed a series of experiments to define the molecular mechanism(s) underlying the unique CNS neuronal sensitivity to Nf1 heterozygosity. First, Nf1 heterozygosity decreases cAMP levels in...

Thus, individual NEP cells are multipotent and can differentiate into most major types of cell in the CNS and PNS and that PNS differentiation involves a transition from a NEP stem to another more limited, p75-immunoreactive, neural crest stem cell....
