文档介绍：SELF-ASSESSMENT IN HISTOLOGY QUESTIONS 七,NERVOUS TISSUES 1Bipolar neurones have one major dendrite which arises from the cell body at the side opposite to the origin of the axon.(T) 2The Nissl substance seen in light microscopy represents the numerous mitochondria found in the neurone cell body.(F) 3Dispersed chromatin and aprominent nucleolus are characteristic features of neurone nuclei.(T) 4Motor neurones are an example of pseudo-unipolar neurones.(F) 5With the electron microscope, the neurone cell body is characteristically packed with microtubules and microfilaments but these do not extend into the axon hillock or axon.(F) 6Non-myelinated axons in peripheral nerves are supported by Schwann cells.(T) 7The nodes Ranvier seen with light microscopy are equivalent to the mesaxons seen by electron microscopy.(F) 8In humans, the process of myelination pleted by birth.(F) 9Myelin sheaths are formed by oligodendrocytes in the central nervous system and by Schwann cells in peripheral verves.(T) 10 Schwann cells produce myelin by wrapping axons in essive layers of smooth endoplasmic reticulum.(F) 11 Synaptic transmission is believed to involve release of aquantum of neurotransmitter into the synaptic cleft, thereby initiating an action potential at the post-synaptic membrane.(T) 12 Terminal boutons contain prolific rough endoplasmic reticulum for wynthesis of neurotransmitter substan
