This set of Tissue Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Neural Tissue Engineering using Stem Cells”.
1. The majority of neural tissue found in the CNS consists of two cell types, neuronal cells, and ____________
a) red blood cells
b) adherent cells
c) stem cells
d) glial cells
Explanation: The CNS comprises of the mind and the spinal string with the blood-cerebrum obstruction confining the kinds of biomolecules that can achieve these organs. Most of the neural tissue found in the CNS comprises of two cell types: neuronal cells and glial cells.
2. _______________ produce the myelin sheath insulating neuronal axons.
Explanation: Oligodendrocytes are a kind of huge glial cell found in the focal sensory system. Oligodendrocytes produce the myelin sheath protecting neuronal axons (undifferentiated from Schwann cells in the fringe sensory system), in spite of the fact that some oligodendrocytes (called satellite oligodendrocytes) are not engaged with myelination.
3. ___________ is a progressive nervous system disorder that affects movement.
d) Parkinson’s disease
Explanation: Parkinson’s disease is a dynamic sensory system issue that influences development. Side effects begin step by step, now and again beginning with a scarcely discernible tremor in only one hand. Tremors are normal, yet the turmoil likewise regularly causes firmness or easing back of the development.
4. Dopaminergic neurons of the midbrain are the main source of dopamine.
Explanation: Dopaminergic neurons of the midbrain are the principle wellspring of dopamine (DA) in the mammalian focal sensory system. Their misfortune is related to one of the most unmistakable human neurological issues, Parkinson’s disease (PD).
5. ____________ is rare, inherited neurodegenerative disorder characterized by a loss of medium spiny projection neurons in the striatum.
a) Huntington’s disease (HD)
b) Parkinson’s Disease
c) Cardiac myopathy
d) Alzheimer’s Disease
Explanation: Huntington’s disease (HD) is an uncommon, acquired neuro-degenerative turmoil portrayed by lost medium barbed projection neurons in the striatum. Side effects incorporate loss of solid coordination alongside dynamic psychological decrease.
