Exam 3: The Plasma Membrane and Membrane Potential

Efferent neurons are motor neurons.

Nerves of the autonomic nervous system control skeletal muscle responses.

If neuronal pathways present at birth are not used during sensitive developmental periods, they may be eliminated.

Match the spinal tracts, labelled a. through e., with their characteristics. (Options may be used more than once or not at all.) a.ventral spinocerebellar b.rubrospinal c.lateral corticospinal d.fasciculus cuneatus e.lateral spinothalamic -sensory tract for pain and temperature

The blood-brain barrier prevents an increase in the concentration of potassium ions in the ECF surrounding brain cells.

Microglia are phagocytic cells delivered by the blood to the central nervous system.

Efferent neurons lie primarily in the central nervous system.

The ____________________ lobes of the cerebral cortex are responsible for initial processing of visual input.

Different parts of the body are not represented by equal areas of the sensory homunculus of the parietal lobe.

Which statement correctly describes the peripheral nervous system?

Which of these statements is correct for procedural memories?

Which of the following statements applies correctly to brain cells?

The inability to recall recent past events following a traumatic event is known as ____________________, whereas the inability to store new memories for later retrieval is called ____________________.

Which part of the brain controls thirst and urine output, food intake, and body temperature, among other things?

Ninety percent of the cells within the CNS are neurons.

A(n) ____________________ is a bundle of neuronal axons of similar function within the CNS.

Which of the following is NOT accomplished by the cerebral cortex?

Match the glial cells, labelled a. through d., with their descriptions. a.astrocytes b.oligodendrocytes c.ependymal cells d.microglia -line the brain ventricles

Which of these statements describes the blood-brain barrier?
