Introduction to Nervous System

What is the basic function of Central Nervous System?

• Receives sensory input

• Generate motor output

• Integration

• Differentiation

What structure can you found in this multipolar neuron?

• Soma

• Dendritic

• Receptors

• Axon

Based on the sagittal section of brain, can you tell me the direction of central nervous system?

Is the Grey matter and White matter in central nervous system located at the same position such as deep and superficial?

• Yes, both grey matter located at the superficial and white matter at deep

• No, in brain, superficial matter located at the superficial (cerebral cortex), but in spinal cord located at the deep.

• I think basal ganglia (several mass grey matter) located at the white matter

• All of the above correct.

The meninges that cover the brain?

• Dura

• Falx cerebri

• Arachnoid

• Pia meter

Brain consists of 3 parts, what is it?

• Presencephalon

• Metencephalon

• Mesencephalon

• Rhombocephalon

Peripheral Nervous System (PNS) composed of 4 types of nerves, do you know what is it?

• Spinal Nerves, Cranial Nerves, Ganglia, Nerve Plexus

• Radial Nerve, Ulnar Nerve, Tract, Brachial Plexus

• Spinal Nerve, Fascial Nerves, Ganglia, Nerve Plexus

• Trigeminal Nerve, Fascial Nerve, Ganglia, Nerve Plexus

There are 31 segments on Spinal Nerves, and 12 pairs on Cranial Nerves. So what Cranial Nerves that are not part of PNS? And also which pairs of Cranial Nerves that is not supply head and neck?

• Optic Nerve, Fascial Nerve

• Optic Nerve, Accessory Nerve

• Vagus Nerve, Olfactory Nerve

• Optic Nerve, Vagus Nerve

There are two parts of ganglia, can you help me to know?

• Dorsal root ganglion

• Sensory ganglion

• Trigeminal ganglion

• Autonomic ganglion
