| A | B |
| spinal cord | collection of neurons and supportive tissue running from the base of the brain down the center of the back, protected by a column of bones (spinal column) |
| CNS | The portion of the nervous system consisting of the brain and the spinal cord |
| Biological Psychology | is the field that relates behavior to bodily processes, especially the workings of the brain |
| Spinal Nerves | 31 pairs arising from ganglia in the spinal cord |
| Cranial Nerves | 12 pairs arising directly from the brain; innervate target located largely in the head |
| Meninges | layers of connective tissue lying under the skull and on the brain |
| Dura Mater (hard mother) | part of the Meninges immediately under the bone |
| Arachanoid (spider) | membrane between the two others; contains cerebrospinal fluid |
| Pia Mater (soft mother) | adheres to the brain |
| Ventricular System | Series of 4 cavities filled with cerebrospinal fluid (CSF) |
| 2 lateral ventricles | side ventricles in the ventricular systm |
| 3rd ventricle | midbrain ventricle |
| 4th ventricle | ventricle anterior to the cerebellum |
| Cerebrospinal Fluid | Filtered blood plasma that is produced from inside the ventricles by tissue called the choroid plexus |
| PNS | all portions of the nervous system outside the brain and spinal cord; it includes sensory and motor nerves |
| somatic nervous system | subdivision of PNS that connects to sensory receptors and to skeletal muscles; sometimes called the skeletal nervous system |
| autonomic nervous system | subdivision of PNS that regulates the internal organs and glands |
| biofeedback | method for learning to control bodily functions, including ones usually though to be involuntary, by attending feedback from an instrument that monitors the function and signals changes in it |
| Motor Nerves | carry message from CNS to muscles, glands, and visceral organs |
| Sensory Nerves | carry messages from receptors in the perhipheal organs to the CNS |
