Nervous system Quiz

Cells that support neurons in ganglia of the PNS are

• Schwann cells

• Satellite cells

• Osteocytes

• Oligodendrocytes

Small, phagocytic neuroglia derived from monocytes are

• Osteocytes

• Oligodendrocytes

• Microglia

• Ependymal cells

These cells form myelin sheath around PNS neurons

• Schwann cells

• Satellite cells

• Osteocytes

• Oligodendrocytes

Impulse receiving portion of neuron is called

• Cell body

• Dendrites

• Axon

• Axon terminal

Neurons that have one process extending from cell body and are always sensory neurons are called

• Unipolar Neuron

• Bipolar Neuron

• Multipolar Neuron

Neuron that have one main dendrite and one axon & are found in retina, inner ear, olfactory area of brain

• Unipolar Neuron

• Bipolar Neuron

• Multipolar Neuron

Neuron having several dendrites and one axon, located in brain or spinal cord

• Unipolar Neuron

• Bipolar Neuron

• Multipolar Neuron

Neuron that transmit sensory nerve impulses from receptors of skin, sense organs to the CNS are called Afferent/Sensory neurons.

• True

• False

It is fine connective tissue containing many blood vessels

• Dura Mater

• Arachnoid Mater

• Pia Mater

It consist of 2 layers of fibrous tissue. Outer layer is on inner surface of skull bone and inner layer provides protective covering for the brain.
