| 6531804857 | Characteristics & Functions of Nervous Tissue | Sensory Input | Intergration | Motor Output 1) Responsive 2) Long-lived, mostly amitotic 3) Conductive 4) Secretory | 0 | |
| 6531807676 | Types of Neuroglia CNS (Specific Support Roles) | 1) Astrocytes: control capillary permeability, control chemical enviornment around neurons, promote neuron growth and synapse formation, form scar tissue around damaged neurons 2) Microglia: type of macrophage 3) Ependymal cells: ciliated cells lining cavities of brain and spinal cord Makes the cerebrospinal fluid (CSF) 4) Oligodendrocytes - produce myelin sheaths (octopus shaped) | 1 | |
| 6532063863 | Types of Neuroglia PNS (Specific Support Roles) | 1) Satellite cells: surround cell bodies in ganglia-establish a neuron friendly environment 2) Schwann cells: form myelin sheath, regenerate peripheral nerve fibers | 2 | |
| 6531810768 | Differences in Type (from the CNS to the PNS) | Central Nervous System: Brain & Spinal Cord Peripheral Nervous System: Bundles of axons and ganglia outside of CNS In CNS - clusters called nuclei In PNS - clusters called ganglia | 3 | |
| 6531813497 | Divisions of the Nervous System | Afferent: Sensory - somatic and Visceral Efferent: Motor - CNS to muscles, glands (effectors) - somatic (voluntary), visceral (sympathetic & parasympathetic) |  | 4 |
| 6531816101 | Type of Neurons (structure based differences and where each is most likely to be found) | 1) Multipolar - most neurons are this type 2) Bipolar - receptor cells (olfactory receptors) 3) Unipolar - mainly sensory in ganglia of PNS peripheral fiber has receptive ending, central fiber enters CNS (carry signals to spinal cord) 4) Anaxonic - dendrites only, quick communication and processing, brain, retina, adrenal medulla | 5 | |
| 6531819750 | Membranes Surrounding the CNS | Dura Mater (Outer) [extends to S2] Arachnoid (Middle) [extends to S2] Pia Mater (Inner) [continues to posterior coccyx] = Meninges | 6 | |
| 6531822926 | The Tracts (Fasciculi) | 1.) Motor Tracts (Lateral Corticospinal) Sensory for movement and command from brain to spinal cord 2.) Sensory Tracts (Lateral & Anterior) Pain and Temperature, spinothalamic, from skin 3.) Sensory Tracts (Dorsal) light touch, deep pressure, proprioceptive senses [Fasciculus Gracilis] from sacral and lumbar body areas up to the brain [Fasciculus Cuneatus] from thoracic and cervical body areas up to the brain | 7 | |
| 6531824931 | 1st, 2nd, and 3rd Order Neurons (begin, end, & where specific tracts dessucate) | Ascending Pathways 1st order neurons from receptors to spinal cord or brain stem, synapse with 2nd order,(decussate here) transmits to cerebellum or thalamus 3rd order, from thalamus to somatosensory area cerebral cortex (Pain Receptors 3 steps) | 8 | |
| 6531826740 | Major Plexuses (Sections of the body they cover) | 1.) Cervical Plexus (Head, neck, shoulders) 2.) Brachial Plexus (Chest, shoulders, arms, hands) 3.) Lumbar Plexus (Back, adbomen, groin, thighs, knees, calves) 4.) Sacral Plexus (Pelvis, butt, genitals, thighs, calves, feet) 5.) Coccygeal Plexus (small region over coccyx) | 9 | |
| 6531833913 | Structures found on the Brain (Gyri and Sulci) | Rostral (Front hemisphere) Caudal (Back) Cerebrum - interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement. Longitudinal Fissure Corpus Callosum Cerebellum - located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance. Brainstem - includes the midbrain, pons, and medulla. It acts as a relay center connecting the cerebrum and cerebellum to the spinal cord (automatic functions) Diencephalon |  | 10 |
| 6531833914 | Sections of the Brain & How they are Connected | Prosencephalon [forebrain] - Cerebrum, cerebral, cortex, white matter, thalamus, hypothalamus, retina Mesencephalon [midbrain] - Brain Stem, Midbrain Rhombencephalon [hindbrain] - Pons, Cerebellum, Medulla Oblongata | 11 | |
| 6531844727 | Disorders & Diseases Concerning the Nervous Tissue, Brain, & Spinal Cord | Multiple Sclerosis Tay-Sachs disease Flaccid Paralysis Spastic Paralysis Paraplegia Quadriplegia Poliomyelitis Spina Bifida Cystica Meningitis - Inflammation of Meninges Parkinson - degeneration of dopamine-releasing neurons in substantia nigra | 12 | |
| 6531853650 | Neurotransmitters discussed in class (and their functions) | ACh - a chemical released by nerve cells to send signals to other cells | 13 | |
| 6544242791 | Sympathetic System | prepares the body for fight or flight reactions. Action of this system results in accelerated heart rate, increased blood pressure and blood flow away from the periphery and digestive system toward the brain, heart and skeletal muscles. It also causes adrenaline to be released, temporarily increasing physical strength. | 14 | |
| 6544245324 | Parasympathetic System | brings the body back to a state of equilibrium. It slows heart rate and decreases the release of hormones into the blood stream. The activity of the parasympathetic system causes more localized reactions than does the sympathetic system as much of its output is to specific organs. | 15 | |
