Nervous Tissue and Nerve Question Answer Sheath of Schwann cell containing cytoplasm and nucleus that encloses myelin Neurilemma Chromatophilic Substance (Nissl Corresponds to rough endoplasmic reticulum in other cells bodies) Network of fine threads extending into nerve fiber Neurofibrils Substance of Schwann cell composed of lipoprotein that insulates axons and Myelin Sheath increases impulse speed Neuron process with many branches that conducts an impulse toward the cell Dendrites body 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 Axon impulse away from the cell body 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 Motor (efferent neuron) glands) 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 Ependymal cell cerebrospinal fluid
