• Schwann cells

What is the function of microglia in the CNS?

• To carry out phagocytosis in inflamed brain tissue

• To transfer nutrients from the blood to the neurons

• To hold nerve fibers together and produce the myelin sheath

• To support nerve fibers and form myelin sheaths

Which type of glial cells are found only in the peripheral nervous system?

What is the function of dendrites in a neuron?

• To conduct impulses to the CNS from the receptor

• To conduct impulses from the CNS to effectors

• To branch from the cell body and act as receptors

What is the function of axons in a neuron?

• To conduct impulses to the CNS from the receptor

• To conduct impulses from the CNS to effectors

• To branch from the cell body and act as receptors

What is the function of the input zone in a neuron?

• To conduct impulses to the CNS from the receptor

• To conduct impulses from the CNS to effectors

• To summate impulses at the axon hillock

• To transmit impulses to the telodendria and synaptic knobs
