What are specialized cells that do all the support activities for the nervous system?
Neuroglia are the supporting cells of the NS. There are four types in the central nervous system (CNS) and two types in the peripheral nervous system (PNS). They all have functions that contribute to the overall health of neuron cells.
Which of the following PNS neuroglia help to form myelin sheaths around larger nerve fibers in the PNS?
The Schwann cells in the peripheral nervous system (PNS) help to form myelin sheaths around larger nerve fibers. These cells wrap around the nerve fibers to provide insulation and support for faster nerve impulse conduction.
Which of the following cell types insulates neurons in the PNS?
neurona;
What type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
Are nerves more myelinated or unmyelinated in the CNS?
Nope. They can be found in the PNS as well. The myelinated ones in the CNS are made my Schwann cells. And the ones made in the PNS are made by oligodendrocytes.
What are the types of neuroglia?
There are 6 different types CNS: astrocytes, microglia, ependymal, and oligodendrocytes, PNS: satellite cells, and schwann cells
What are specialized cells that do all the support activities for the nervous system?
Neuroglia are the supporting cells of the NS. There are four types in the central nervous system (CNS) and two types in the peripheral nervous system (PNS). They all have functions that contribute to the overall health of neuron cells.
What cells os only found in the PNS?
Satellite cells are only found in the peripheral nervous system (PNS). These cells provide support and nutrients to the neurons in the PNS.
Which of the following PNS neuroglia help to form myelin sheaths around larger nerve fibers in the PNS?
The Schwann cells in the peripheral nervous system (PNS) help to form myelin sheaths around larger nerve fibers. These cells wrap around the nerve fibers to provide insulation and support for faster nerve impulse conduction.
Are neurons and neuroglia found in connective tissue?
No, there are four types of tissue; muscular, epithelial, connective and nervous tissue. Neurons are categorised in the nervous tissue.
Which of the following cell types insulates neurons in the PNS?
neurona;
What is able to divide neurons or neuroglia?
Neuroglia
Is cerebrospinal fluid found in the cavity of PNS?
No, CSF is found only in the central nervous system.
Cell type found in nervous tissue?
The main cell type found in nervous tissue is the neuron. Neurons are responsible for transmitting electrical signals within the nervous system and are specialized for communication through both electrical and chemical signals.
What type of neuroglia forms the myelin sheath?
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
Are nerves more myelinated or unmyelinated in the CNS?
Nope. They can be found in the PNS as well. The myelinated ones in the CNS are made my Schwann cells. And the ones made in the PNS are made by oligodendrocytes.
Involuntary muscle is controlled by which organ?
All muscle types are controlled by the nervous system (CNS and/or the PNS).
