Anatomy
| Question | Answer |
|---|---|
| Sarcoplasmic reticulum | Contain network of tubules and sacs |
| Myofibrils | Bundles of fine cytoskeletal filaments that extend lengthwise along a skeletal muscle fiber |
| Sarcomere | Segment of myofibrils |
| ATP | produces muscle energy |
| Glia | Supports the function of neurons |
| Microglia | Small cells found in the CNA |
| Oligodendrocytes | Help hold nerve fiber together |
| Dendrites | Receive stimuli and conduct electrical signals toward the cell body and axon of the neuron. |
| Axon | Conduct nerve impulses away from the body |
| Synapse | where nerve information is transmitted from one neuron to another |
| Fasciicles | Bundles of nerve fibers |
| Synaptic cleft | e space between a synaptic knob and the plasma membrane of a postsynaptic neuron |
| acetylcholine | Neurotransmitter |
| Cholecystokinin (CCK | Mostly excitatory; transmits pain information |
| Central sulcus | groove between the fron-tal and parietal lobe |
| Gray | Integration of spinal reflexes and filtering of information going to higher centers (as in gated pain control) |
| White matter | Ascending tracts conduct sensory information to higher CNS centers; descending tracts conduct motor information from higher CNS centers |
