| Question | Answer |
|---|---|
| What special covering membranes protect and support the spinal cord and brain? | Meninges |
| Name the three cranial meninges | Arachnoid mater, dura mater and pia mater |
| Which layer covers the brain and spinal cord containing dural septa? | Dura mater |

| which type of neuron conducts nerve impulses toward the central nervous system? | sensory |
| Bublike structure at the distal ends of axon terminals that contain storage saves for neurotransmitters are called what? | synaptic ends bulbs |
| which neuroglials cell is phagocytic? | microglial cell |
| A neuron that contains several dendrites and one axon is classified as a what? | multipolar |
| the portion of a neuron that contains the nucleus and cytoplasam is called what? | celly body |
| the lipid and portion covering aroudn many peripheral axon is called what? | myelin sheath |
| the two types of cells taht compose the nervous system are neurons and what? | neurogila |
| neurons with one dendrite and one axon are classified as what? | bipolar |
| the functional contract between two neurons or between a neuron and and effector is called what? | synapse |
| rami | short spinal nerves branch into three or four mixed distal rami. |
| what are the 4 rami? | small dorsal ramus, largest ventral ramus, tiny meningeal branch and rami communicantes |
| what is one rami called? | ramu |
| nerve plexuses are found where? | cervical, brachial, lumbar, and sacral regions |
