OBE Nervous System CNS I 2020

Central nervous system is made up of:

I. autonomic motor nerves

II. cranial nerves

III. spinal cord

IV. brain

• I and II

• II and III

• III and IV

• I and IV

Brainstem is made up of

• Thalamus and hypothalamus

• Epithalamus and cerebrum

• Mesencephalon and pons varolli

• Basal ganglia and cerebellum

Diencephalon is made up of

• Cerebrum and cerebellum

• Mesencephalon and pons

• Thalamus and epithalamus

• Spinal cord and medulla oblongata

The function of dendrite in the neuron is

• integrate the impulse received by neuron

• store neurotransmitters

• receive impulse from outside of neuron

• control all activity in the neuron

What is the function of sensory neuron?

• allow impulses to pass through it

• carry impulse from the CNS to the effectors (muscles and glands)

• carry sensory input from receptors to the CNS

Which of the following is NOT a neuroglia ?

• unipolar

• astrocytes

• microglia

• satellite cells

Neuroglia that produce myelin sheath are

• unipolar and astrocytes

• satellite cells and microglia

• oligodendrocytes and Schwann cells

• Satellite cells and ependymal cells

Neuroglia which provide nutrition to the neurons in CNS is

• microglia

• astrocytes

• satellite cells

• oligodendrocytes

Neuroglia which phagocytes invading pathogens and damaged tissues is

• microglia

• astrocytes

• ependymal cells

• oligodendrocytes

Which neuroglia helps in the circulation of cerebrospinal fluid (CSF)?

• oligodendrocytes

• ependymal cells
