What is not true about glial cellsa) modified glial cell called Schwann cell secrets myelin sheath b) assist in nourishment of neurons C) modulate nerve impulse d) secrete neurotransmitters that facilitate synaptic transmission

Dear student

The Glial cells are also known as Nueroglia and provide nourishment to the neurons. They are modified glial cell called Schwann cell secrets myelin sheath and help in modulation of nerve impulse. Glial cells do not secrete neurotransmitters. Hence, option d is incorrect.

D) Secrete neurotransmitters that facilioate synaptic transmission. Neurotransmitters are made in the cell body of the neuron and then transported down the axon to the axon terminal. Molecules of neurotransmitters are stored in small "packages" called vesicles.
