Nervous Tissue and Nerve
| Question | Answer |
|---|---|
| Sheath of Schwann cell containing cytoplasm and nucleus that encloses myelin | Neurilemma |
| Corresponds to rough endoplasmic reticulum in other cells | Chromatophilic Substance (Nissl bodies) |
| Network of fine threads extending into nerve fiber | Neurofibrils |
| Substance of Schwann cell composed of lipoprotein that insulates axons and increases impulse speed | Myelin Sheath |
| Neuron process with many branches that conducts an impulse toward the cell body | Dendrites |
| Branch of an axon | Collateral |
| Star-shaped neuroglia between neurons and blood vessels | Astrocyte |
| Nerve fiber arising from a slight elevation of the cell body that conducts an impulse away from the cell body | Axon |
| Transmits impulse from sensory to motor neuron within central nervous system | Interneuron |
| Transmits impulse out of the brain or spinal cord to effectors (muscles and glands) | Motor (efferent neuron) |
| Transmits impulse into brain or spinal cord from receptors | Sensory (afferent neuron) |
| Myelin-forming neuroglia in brain and spinal cord | Oligodendrocyte |
| Phagocytic neuroglia in central nervous system | Microglia |
| Structure capable of responding to motor impulse | Effector |
| Specialized mass of neuron cell bodies outside the brain or spinal cord | Ganglion |
| Cells that cover the inside spaces of the brain ventricles and help regulate cerebrospinal fluid | Ependymal cell |
