Attempt the Quiz - Neural Development

Here are a few simple Quiz questions that relate to Neural development and abnormalities from the lecture. Some questions may require some additional research. 1 The process called "apoptosis":   is a pathological form of cell death   results from acute cellular injury   is characterised by cell swelling and lysis   is involved in programmed cell death for normal tissue turnover   all of the above are correct 2 Which of the following endocrine components originates from neural ectoderm?   neurohypophysis   adenohypophysis   adrenal cortex   thyroid   parathyroid 3 During early development, the neural tube is bent at three locations, and the pontine flexure is located in the:   telencephalon   diencephalon   mesencephalon   metencephalon   myelencephalon 4 Segmentation of the brain into functionally distinct domains is known as:   primary neurulation   secondary neurulation   primary brain vesicles   secondary brain vesicles   neuromeres 5 The central nervous system (CNS) cells that share lineage with monocytes are the:   cerebral granular cells   microglia cells   oligodendroglia cells   astrocytes   Schwann cells 6 Closure of the neural pores:   begins at the 4th somite and then progresses rostrally and caudally   is essential for further differentiation of the neural tube   causes formation of brain vesicles   is influenced by the notochord   all of the above 7 The myelin sheath of a peripheral nerve fiber is formed by the cells that originate from:   mesenchymal cells   neuroblasts   the neural crest   glioblasts   primitive blood cells 8 Hydrocephaly results from:   aqueduct stenosis   choroidal plexus papilloma   chronic meningitis   hydromyelin   subarachnoid hemorrhage 9 In spina bifida occulta:   the vertebral arches in the affected area are underdeveloped but the defect is covered by the skin   the neural groove fails to close   a cyst, containing neural tissue, leptomeninges and glial tissue, appears   only the meninges are present in the cyst   all of the above are present 10 The a-fetoprotein levels in amniotic fluid are increased in:   neural tube defects   hydatidiform mole   an omphalocele   multiple pregnancies   all of the above Additional Information:
