| Middle layer of the three membranes(meninges) that surround the brain and spinal cord. | Arachnoid membrane |
| Type of glial(neuroglial) cell that transports water and salts from capillaries. | Astrocyte |
| Nerves that control involuntary body functions of muscles,glands,and internal organs. | Autonomic nervous system |
| Microscopic fiber that carries the nervous impulse along a nerve cell. | Axon |
| Blood vessels(capillaries) that selectively let cartain substances enter the brain tissue and keep other substances out. | Blood-brain barrier |
| Lower portion of the brain that connects the cerebrum with the spinal cord;includes the pons and medulla oblongata. | brainstem |
| Collection of spinal nerves below the end of the spinal cord | Cauda equina |
| Part of a nerve cell that contains the nucleus. | Cell Body |
| Brain and the spinal cord. | Central Nervous System (CNS) |
| Posterior part of the brain that coordinates muscle movements and maintains balance. | Cerebellum |
| Outer Reigon of the cerebrum, containing sheets of nerve cells;gray matter of the brain. | Cerebral Cortex |
| Circulates throughout the brain and spinal cord. | Cerebrospinal Fluid (CSF) |
| Largest part of the brain; responsible for voluntary muscular activity,vision,speech,taste,hearing,thought,and memory. | Cerebrum |
| Twelve pairs of nerves that carry messages to and from the brain withregard to the head and neck (except the vagus nerve). | Cranial Nerves |
| Microscopic branching fiber of a nerve cell that is the first part to receice the nervous impulse. | Dendrite |
| Thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord. (Latin for "hard mother") | Dura Mater |
| Carries messages away from the brain and spinal cord;motor nerve. | Efferent Nerve |
| Glial cell that lines membranes within the brain and spinal cord and helps form cerebrospinal fluid. | Ependymal Cell |
| Collection of nerve cell bodies in the peripheral nervous system. | Ganglion (plural:ganglia) |
| Supportive and connective nerve cell that does not carry nervous impulses. Examples are Astrocytes,Microglial cells,ependymal cells, and Oligodendrocytes. | Glial Cell (neuroglial cell) |
| Sheet of nerve cells that produces a rounded ridge on the surface of the cerebral cortex,convolution | Gyrus (plural:gyri) |
| Portion of the brain beneath the Thalamus,controls sleep,appetite,body temperature, and secretions fromt he pituitary gland. | Hypothalamus |
| Part of the brain just above the spinal cord;controls breathing,heartbeat,and the size of blood vessels;nerve fiber cross over here. | Medulla Oblongata |
| Three protective membranes the aurround the brain and spinal cord. | Meninges |
| Phagocytic glial cell the removes waste products from the central nervous system. | Microglial Cell |
| Carries messages away from the brain and spinal cord to muscles and organs,efferent nerve. | Motor Nerve |
| Covering of white fatty tisue that surrounds and insulates the axon of a nerve cell.Myelin speeds impulse conduction along axons. | Myelin Sheath |
| Macroscopic cord-like collection of fibers(axons and dendrites) that carry electrical impulses. | Nerve |
| Nerve cell that carries impulses throughout the body. | Neuron |
| Chemical messenger released at the end of a nerve cell.It stimulates or inhibits another cell,which can be a nerve cell,muscle cell,or gland cell.Exaples of neurotransmitters are acetylcholine,norepinephrine,dopamine, and serotonin. | Neurotransmitter |
| Glial cell that forms the myelin sheath covering axons.Also called oligodendrocyte. | Oligodendroglial cell |
| Involuntary,autonomic nerves that regulate normal body functions such as heart rate, breathing,and muscles of the gastrointestinal tract. | Parasympathetic nerves |
| Essential,disinguishing tissue of any organ or system.The parenchyma of the nervous system includes the brain,spinal cord,and neurons.Parenchymalcells of the liver are hepatocytes,pasrenchymaltissue of the kidney includes the nephrons.whereurine is formed | Parenchyma |
| Nerves outside the brain and spinal cord;cranial,spinal.and autonomic nerves. | Peripheral Nervous System |
| Thin,delicate inner membrane of the meninges. | Pia Mater |
| Large,interlacing network of nerves.EX:lumbosacral,cervical,and brachial(brachi/o menas arm) plexuses. | Plexus (plural;plexuses) |
| Part of the brain anterior to the crebellum and between the medull and the rest of the midbrain.It is a bridge connecting various parts of the brain. | Pons |
| Organ the recieves a nervous stimulus and passes it on to afferent nerves.The skin,eyes,ears,and taste buds | Receptor |
| Nerve extending from the base of the spine down the thigh,lower leg,and foot.Sciatica is pain or inflammation along the course of the nerve. | Sciatic nerve |
| Carries messages toward the brain and spinal cord from a receptor;afferent nerve. | Sensory nerve |
| Thirty one pairs of nerves arising from the spinal cord. | Spinal nerves |
| Agent of change(light,sound,touch) in the internal or external environment that evokes a response. | Stimulus(plural:stimuli) |
| Connective and supporting tissue of an organ.Glial cells are the stromal tissue of the brain. | Stroma |
| Depression or grooove in the surface of the cerebral cortex;fissure. | Sulcus (plural:sulci) |
| Autonomic nerves that influence bodyily functions involuntarily in times of stress. | Sympathetic Nerves |
| Space through which a nervous impulse travels between nerve cells or between nerve and muscle or gladular cells. | Synapse |
| Main relay center of the brain.It conducts impulses between the spinal cord and the cerebrum;imcoming sensory messages are relayed through the thalamus to appropriate centers in the cerebrum. | Thalamus |
| Thenth cranial nerve (cranial nerve x); its branches reach to the larynx,trachea,bronchi,lungs,aorta,esophagus, and stomach. | Vagus Nerve |
| Canals in the brain that contain cerebrospinal fluid. | Ventricles of the Brain |
