  1. Nervous System Review Chapter 12, 13 & 14

  2. Which Neuroglia cell is responsible for cleaning up around neurons? • Astrocytes • Oligodendrocytes • Microglia • Ependymal cells

  3. Which Neuroglia cell Produce Myelin sheaths in the CNS? • Astrocytes • Oligodendrocytes • Microglia • Ependymal cells

  4. Depolarization of the Axon shifts the membrane potential towards …. • -90mV • -85mV • -70mV • 0 mV

  5. The brachial plexus serves the following areas: • Neck & Shoulder Girdle • Shoulder Girdle & Arm • Neck & Arm • Thorax & Arm

  6. The Synaptic vesicles attach to the pre-synaptic membrane after: • Calcium ions leave the cytoplasm • Calcium entering the synaptic terminal • Reabsorption of calcium in the endoplasmic reticulum • Active transport of calcium into the synaptic vesicles

  7. Spinal nerves are mixed nerves when they contain: • White matter and gray matter • Both dorsal and ventral roots • Both sensory and motor fibers • Ascending and descending pathways

  8. Spinal nerves from the sacral region of the cord communicate with the ________ muscles. • Shoulder • Intercostal • Abdominal • Leg

  9. Damage to the ventral root of a spinal nerve: • Blocks the output of the skeletal muscle • Disables the spinal cord to process information • Blocks the sensory input • Disables the brain to communicate with the spinal cord

  10. Autonomic center that controls blood pressure, heart rate and digestion: • Medulla Oblongata • Pons • Mesencephalon • Cerebellum

  11. Sensory information is processed and relayed to the cerebrum by the: • Midbrain • Thalamus • Pons • Cerebellum

  12. What connects the third & Fourth Ventricle? • Central Canal • Interventricle foramina • Cerebral aquaduct • Tentorium cerebelli

  13. Which of the following 2nd Ventricles will form the Medulla Oblongata? • Diencephalon • Mesencephalon • Myelencephalon • Telencephalon

  14. CSF …. • Is secreted by the choroid plexus • Is formed by a passive process • Contains blood cells and blood plasma • Is normally produced twice as fast as it is removed

  15. The auditory cortex is in the … • Frontal Lobe • Temporal Lobe • Parietal Lobe • Occipital Lobe

  16. Which system of the brain deals with memory and emotions? • The Prefrontal lobe • The Limbic system • The Thalamus • The Temporal Lobe

  17. How many pairs of spinal nerves do we have? • 31 • 6 • 12 • 22

  18. Vision problems occur if the _______ nerve is damaged. • Optic • Oculomotor • Trochlear • Abducens

  19. Cranial Nerve X controls the Heart, Lungs, Liver, Stomach and intestines. • Facial • Trigeminal • Vagus • Olfactory

  20. The surface of the post-central gyrus (Humunculus) contains the …… • Primary motor cortex • Visual cortex • Olfactory cortex • Primary sensory cortex

  21. The Third Ventricle is located… • Within the hemispheres of the cerebrum • Between cerebellum and pons • In the Diencephalon

  22. Neuroglia … • Conduct impulses • Are helper cells • Send messages • Break down neurotransmitters

  23. The transmembrane potential within the Axolemma in a resting neuron is • Positive • Negative • Zero

  24. The Axon is connected to the Soma at the • Dendrites • Axon hillock • Synaptic terminal • Synaptic vesicle

  25. Neurotransmitter are stored within… • The axon • The Axon terminal • The vesicles • Within the Synaptic cleft

  26. When Sodium channels open up the Axon … • Repolarizes • Depolarizes • Neutralizes • Hyperpolarizes

  27. The cerebellum & Pons develop from the …. • Metencephalon • Telencephalon • Myelencephalon • Diencephalon

  28. Which Neuroglia is found in the PNS? • Astrocyte • Satellite cell • Oligodendrocyte • Microglia

  29. The Motor Humunculus is in the • Occipital lobe • Temporal lobe • Frontal lobe • Parietal lobe
