Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Supporting cells in nervous tissue are called
A
neurons
B
neuroglia
C
myofibrils
D
None of the above
Explanation: 

Detailed explanation-1: -These are the glial cells (neuroglial cells), together termed the neuroglia. Supporting, or glia, cells bind neurons together and insulate the neurons. Some are phagocytic and protect against bacterial invasion, while others provide nutrients by binding blood vessels to the neurons.

Detailed explanation-2: -Glial (Neuroglial) cells do not conduct nerve impulses, but, instead, support, nourish, and protect the neurons. Glial cells are far more numerous than neurons and, unlike neurons, are capable of mitosis.

Detailed explanation-3: -Neuroglia are a large class of neural cells of ectodermal (astroglia, oligodendroglia, and peripheral glial cells) and mesodermal (microglia) origin. Neuroglial cells provide homeostatic support, protection, and defense to the nervous tissue.
