| ANS | Consist of ganglia on either side of the spinal cord. |
| ANS | Nerves that control the involuntary actions of the body, such as heartbeat, pupil size and rate of breathing |
| ANS | Divided into the Sympathetic and Parasympathetic NS |
| Arachnoid Membrane | Second or middle layer of the meninges |
| Autonomic Nervous System | ANS |
| Axon | Extends away from the cell body and conducts impulses away from the nerve cell |
| Brainstem | Made up of the midbrain, pons and medulla oblongata. |
| Brainstem | Connects the cerebral hemispheres with the spinal cord. |
| CNS | Consists of the brain and spinal cord protected by the meinges and cerebrospinal fluid |
| CSF | Cerebrospinal fluid |
| Central Nervous System | CNS |
| Cerebellum | Located at the back of the head below the cerebrum. |
| Cerebellum | Maintains balance and coordination and is responsible for voluntary movement. |
| Cerebral Cortex | Outer layer of the cerebrum |
| Cerebrospinal Fluid | CSF - clear, watery fluid that cushions the brain and spinal cord. |
| Cerebrum | Largest part of the brain |
| Cerebrum | Part of the brain responsible for intelligence, learning, judgment, memory, emotion association and discrimination. |
| Cerebrum | Part of the brain containing the hemispheres and lobes |
| Convolutions | Gyri; the elevated portions of the cerebrum |
| Cranial nerves | There are 12 pairs of these orginating in the brainstem. They control the activities of the face and head. |
| Dendrite | Root like structures that receive impulses and conduct them to the cell body. |
| Dura Mater | Outside layer of the meninges |
| Fissures | Sulci; the depressions in the cerebrum |
| Frontal Lobe | Part of the brain that controls motor function |
| Ganglia | Masses of nervous tissue located outside the brain and spinal cord usually located in the wrist area |
| Hypothalamus | Controls vital body functions (heart rate, BP, respiratory rate, digestive tract activity, emotional responses/behavior. Regulates: body temperature, hunger sensations, water balance & thirst, sleep and endocrine activity |
| Impulse | Wave of excitation transmitted through nerve fibers and neurons. |
| Medulla Oblongata | The most vital part of the brain, controls basic life functions including muscles of respiration, heart rate, and blood pressure. |
| Meninges | Three layers of connective tissue membrane that enclose the brain and spinal cord. |
| Myelin Sheath | Fatty tissue that surrounds and protects the axon of a nerve cell of the brain and spinal cord. |
| Myelogram | Record of the spinal cord |
| Nerve | One or more bundle of impulse-carrying fibers that connect the brain and spinal cord with other parts of the body. |
| Neuron | Individual nerve cell. |
| Occipital Lobe | Part of brain that controls eyesight |
| PNS | Consists of the cranial nerves (extending from the brain) and the spinal nerves (extending from the spine) |
| Parietal Lobe | Part of the brain that receives and interprets nerve impulses from the sensory receptors |
| Peripheral Nervous System | PNS |
| Pia Mater | Layer of the meninges that is closest to the brain and spinal cord containing blood vessels |
| Pituitary gland | Master gland (controlling center) located in the brain. |
| Plexus | A large network of nerves |
| Pons | Bridge tissue connecting two parts of an organ. |
| Reflex | Autonomic, involuntary response to some change, either inside or outside the body. |
| Spinal cord | Conducts sensory and motor impulses to and from the brain. |
| Spinal Nerves | 31 pairs of these are enclosed in the spinal cord. |
| Temporal Lobe | Part of brain that controls the senses of hearing and smell. |
| Terminal End Fibers | Branching fibers of the neuron that lead the nervous impulse away from the axon and toward the synapse |
| Thalamus | Monitors sensory stimuli |
