comprehensive Questions and Answers with 100%
Correct Answers | Latest Version
Question 1.
Which tissue shares a developmental origin with brain? A.Skull B.Skin C.Intestine D.Muscle
Kidney
Correct Answer: skin; both are derivatives of the embryonic ectoderm
Question 2.
Which neural cells do not normally proliferate in the adult CNS? A.Neurons B.Astrocytes
C.Oligodendrocytes D.Neurons and Oligodendrocytes E.Neurons and Astrocytes
Correct Answer: neurons and oligodendrocytes; both are post-mitotic cells; these are
polarized cells with complex structures, they die when stimulated to proliferate
Question 3.
Which of the following is a type of neuronal cell death? A.Excitotoxicity B.Apoptosis
C.Necrosis D.Anoikis E.All of the above
Correct Answer: all of the above
Question 4.
Which of these is a neurotrophin? A.Serotonin B.Acetylcholine C.BDNF D.IL-1 E.Insulin
Correct Answer: BDNF (brain derived neurotrophic factor)
Question 5.
What is a neurotrophin?
Correct Answer: a molecule that nourishes, protects, and/or guides a neuron or its
processes
Question 6.
Which of the remaining choices are arguably neurotrophins? serotonin, acetylcholine, IL-1,
or insulin
Correct Answer: serotonin: promotes survival of adult neurons; insulin: promotes
survival of neurons in development and adult life
