nervous tissue
structure and function
| Question | Answer |
|---|---|
| support, insulate, and protect cells | Neuroglia |
| Demonstrate irritability and conductivity, and thus transmit electrical messages from one area of the body to another area | neurons |
| Release neurotransmitters | Neurons |
| Are amitotic | Neurons |
| Able to divide; therefore are responsible for most brain neoplasms | Neuroglia |
| Releases neurotransmitters | Axonal terminal |
| Conducts electrical currents toward the cell body | Dendrite |
| Increases the speed of impulse transmission | Myelin sheath |
| Location of the nucleus | Cell body |
| Generally conducts impulses away from the cell body | Axon |
| Contains primary motor area, which controls voluntary motions | frontal lube |
| Contains primary somatosensory area,which receives information from the skin and skeletal muscles. | parietal lobe |
| Contains a primary visual area. | occipital lobe |
| contains a primary auditory area. | temporal lobe |
| contains a primary association area. | all lobes |
| carries on higher mental functions such as reasoning and critical thinking. | frontal lobe |
