| Question | Answer |
|---|---|
| A star-shaped glial cell with the numerous processes that run in all directions | Astrocyte |
| The part of the peripheral nervous system that supplies neural connections to galnds and to smooth muscles of internal organs | Autonomic nervous system |
| A branch of an axon from a single neuron | Axon collateral |
| The transportation of materials from the neuron cell body to distant regions in the dendrites and axons and from the axon terminals back to the cell body | Axonal transport |
| The spherical central structure of a cell that contains the chromosomes | Cell Nucleus |
| Referring to the topmost 8 segments of the spinal cord in the neck region | Cervical |
| Reffering to the lowesr spinal vertebra (a.k.a. tailbone) | Coccygeal |
| One of the extensions of the cell body that are the receptive surfaces of the neuron | Dendrite |
| The branch of a spinal nerve entering the dorsal horn of the spinal cord that carries sensory information from the peripheral nervous system to the spinal cord | Dorsal root |
| Nonneural brain cells that provide structural nutritional and other types of support to the brain | Glial Cells |
| The study of tissue structure | Histology |
| Reffering to the 5 spinal segments that make up the upper part of the lower back | Lumbar |
| A cellular organelle the provides metabolic energy for the cell's processes | Mitochondrion |
| A nerve cell that has many dendrites and a single axon | Multipolar neuron |
| The ability of the nervous system to change in response to experience or the environment | neural plasticity |
| The hypothesis that the brain is composed of seperate cells that are distinct structurally metabolically and functionally | Neuron Doctrine |
| The study of the life processes of neurons | Neurophysiology |
| A type of glial cell that is commonly associated with nerve cell bodies | Oligodendrocyte |
| The portion of the nervous system that includes all the nerves and neurons outside the brain and spinal cord | Peripheral nervous system |
| Reffering to neurons in the autonomic nervous system that run from the central nervous system to the autonomic ganglia | Preganglionic |
| Structures in the cell body where genetic information is translated (proteins are produced) | Ribosomes |
| The accessory cell that forms myelin in the peripheral nervous system | Schwann cell |
| One of two systems that compose the autonomic nervous system. Arises from the thoracic and lumbar spinal cord | Sympathetic nervous system |
| Referring to the 12 spinal segments below the cervical portion of the spinal cord corresponding to the chest | Thoracic |
