back 32 -one very short process which divides into peripheral and central processes, extends from cell body | back 31 Oligodendrocytes |
back 34 -many processes | back 33 -have two processes attached to the cell body
|
back 36 -carry impulses only away from the CNS | back 35 - conduct impulses only toward the CNS |
back 38 -delicate connective tissue enveloping individual nerve fibers | back 37 -nerves carrying both sensory and motor fibers |
back 40 sheath of connective tissue around all fascicles of nerve fibers | back 39 -sheath of connective tissue enclosing a bundle of nerve fibers
|
back 22 -branch off of the main axon forming more processes | back 21 Axon |
back 24 club-shaped endings by which axons make synaptic contacts with other nerve cells or effector cells
| back 23 -conical area of origin of the axon from the nerve cell body |
back 26 -specialized synapses between neurons and skeletal muscles | back 25 - a narrow extracellular cleft between the presynaptic and postsynaptic membranes |
back 28 Schwann Cells | back 27 -long nerve fibers that are covered by fatty material (myelin) |
back 30 -gaps or indentations in the myelin sheath | back 29 -wrap themselves tightly around the axon in jelly roll fashion, this wrapping is the myelin sheath |
back 12 -cluster of neuron cell bodies in PNS | back 11 -cluster of neuron cell bodies in CNS |
back 14 -provide support for the cell and a means to transport substances throughout the neuron | back 13 Neurofibrils and Chromatophilic Substance |
back 16 1.Dendrites
| back 15 -an elaborate type of rough endoplasmic reticulum involved in the metabolic activities of the cell |
back 18 -form the impulse generating and conducting region of the neuron
| back 17 -receptive regions that bear receptors for neurotransmitters released by the axon terminals of other neurons |
back 20 -bundles of axons in PNS | back 19 -bundles of axons in the CNS |
back 2 -consists of brain and spinal cord | back 1 -the master integrating and coordinating system
|
back 4 -made up of neurons and neuroglia cells | back 3 -includes all nervous elements located outside the central nervous system
|
back 6 -acts as phagocytes | back 5 -serves the needs of the delicate neurons by bracing and protecting them
|
back 8 -play a role in capillary-neuron exchanges and control the chemical environment around neurons | back 7 -myelinate the cytoplasmic extensions of the neurons |
back 10 -slender processes extend
| back 9 -basic functional units of nervous tissue
