Neurological 2
| Question | Answer |
|---|---|
| What does Central nervous system contain? | brain, spinal cord |
| what consists peripheral nervous system? | sensory nerves, motor nerves, autonomic nerves |
| what consists autonomic division of peripheral nervous system? | sympathetic, parasympathetic |
| What kind of cells make up central nerve system? | neuron, glial cells |
| What is the function of glial cells? | provide support and nutrition and oxygen, maintain homeostasis, form myelin, signal transmission, destroy pathogens |
| which type of glial cells are specialized macrophages and exists all reions of brain and spinal cord, multiply when there is damage, and mobile within the brain? | microglia |
| which type of glial cells provide the insulation to axons in the central nervous system? | oligodendroglia |
| which type of glial cells clean up brain "debris", transport nutrients to neurons, hold neurons in place, digest parts of dead neurons, and regulate content of extracellular space? | astrocytes |
| Which type of glial cells line the cavities of the CNS, make up the walls of the ventricles, secrete CSF, beat their cilia to help circulate CSF? | ependymal cells |
| List glial cells in CNS | microglia, oligodendroglia, astrocytes, ependymal cells |
| which type of glial cells are similar to oligodendrocytes, but provide myelination to azons in the PNS, also have phagocytic chapabilities? | Schwann cells |
| which type of glial cells are small cells that line the exterior surface of PNS neurons and help regulate external chemical environment? | satellite cells |
| which type of glial cells are related to gastrointestinal motor activity? | enteric glial cells |
| neurons have axons and dentrites, and glial cells have ________. | axons |
| neurons can generate action potentials and glial cells __________, but they have a _______________. | cannot, resting potential |
| Neurons have ______ that use neurotransmitters, and glial cells do not have those. | synapses |
| what is the process that the part of the axon separated from the neuron's cell nucleus will degenerate if a nerve fiber is cut or crushed? | Wallerian degeneration of axons |
| what is the abnormalities of peripheral nerves which can be secondary to damage of the Schwann cells? | segmental demyelination |
| All axons in the peripheral nervous system are surrounded by a continuous living sheath of Schwann cells. What is this called? | neurolemma |
| Neurolimma play a role in ____________. | axon regeneration |
| axon regeneration only occurs in PNS not CNS. Why? | because there are no Schwann cells in CNS. |
