Answer to: Schwann cells form the myelin sheath around multiple axons at once and the neurilemma which aids in axon regeneration after injury. a...
13. Glutamatergic signaling has been shown to stimulate the surface expression of glucose transporter 1 (GLUT1) in OLs, suggesting that axonal activity might regulate the metabolic support provided by OLs to axons10. Metabolite supply could be facilitated by cytosolic channels within the myelin sheat...
When a neuron is inactive, more of which of the following exist INSIDE the neuron? a. negative ions b. positive ions c. neuropeptides d. myelin sheaths Looking at a string of neurons, you'll see that axons are linked to dendrites across a junction called a/an ...
The structure of a neuron: The above image shows the basic structural components of an average neuron, including thedendrite, cell body, nucleus, Node of Ranvier, myelin sheath, Schwann cell, and axon terminal. What is the main function of dendrite? The functions of dendrites areto receive si...
NKCC was found in both the axoplasm and in the membrane region of axons, as well as in three well-defined regions of the Schwann cell: the external surface along the internodal segment (paranode), the nodal–paranodal region (myelin sheath attachment segment) and the incisures of Schmidt-...
The MFGM structure includes two particular types of lipid –sphingomyelinandgangliosides– that are beneficial for central nervous system health and function. They’re used by your body to construct themyelin sheath[18,19]that helps insulate axons from electrical disruption,[20,21]thus supporting ...
The broad stippled region is compact myelin surrounded by cytoplasmic channels that remain open even after compact myelin has formed, allowing an exchange of materials among the myelin sheath, the Schwann cell cytoplasm, and perhaps the axon as well. The major integral membrane protein of peripheral...
Answer true or false: Saltatory conduction is fast because action potentials only occur at the myelin sheath gaps and sodium ions transfer energy quickly inside myelinated segments. State True or False. Due to collateral branching of neuron axons, one neuron can aff...
a. myelin sheaths. b. ion channels. c. dendrite arcs. d. axon terminals. Glial cells are the \\ a. chemicals released by a neuron that alter activity in other neurons. b. electrically charged molecules found inside each neuron. c. cells that support neu...
The myelin sheath in the central nervous system is made up of: a. neurotransmitters b. GABA c. dendrites d. glial cells Sensory neuron is to motor neuron as a. afferent neuron is to efferent neuron. b. efferent neuron is to aff...
