Nervous System Review

This chapter delves into key concepts of neuroglia functions and nervous system structure, focusing on the roles of different neuroglia cells, including astrocytes, oligodendrocytes, and microglia. It discusses axon depolarization, the function of the brachial plexus, and the mixed nature of spinal nerves. Additionally, the chapter highlights critical brain centers that govern autonomic functions, sensory processing, and emotional memory. Key anatomical structures such as ventricle connections and cranial nerves are also examined, providing a comprehensive review of nervous system components.

  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
