Exam 3: The Plasma Membrane and Membrane Potential

Which of these is NOT a function of astrocytes?

Which of these types of neuroglial cells line the ventricles of the brain?

Which of the following is NOT a function of the basal ganglia?

The ____________________ serves as a relay station and a synaptic integrating centre for preliminary processing of all sensory input on its way to the cortex.

Match the lobes, labelled a. through d., to their descriptions. (Options may be used more than once or not at all.) a.occipital lobes b.temporal lobes c.parietal lobes d.frontal lobes -located to the rear of the central sulcus

Which neuromodulator is implicated as a neural sleep factor?

The limbic association cortex is involved with motivation and emotion.

The brain lacks plasticity of functions.

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

Which of these statements applies to the cerebellum?

Match the lobes, labelled a. through d., to their descriptions. (Options may be used more than once or not at all.) a.occipital lobes b.temporal lobes c.parietal lobes d.frontal lobes -contain the region responsible for personality traits

Match the following functions, labelled a. through f., to their cranial nerves. a.hearing; body balance b.sense of smell c.sensory and motor function to facial regions; chewing d.controls many internal organs in the ventral body cavity e.moves the eye f.sense of vision -optic

Match the lobes, labelled a. through d., to their descriptions. (Options may be used more than once or not at all.) a.occipital lobes b.temporal lobes c.parietal lobes d.frontal lobes -located at the back of the head

Describe the structure and functions of the spinal cord.

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 -tract that terminates in the cerebellum

The cerebellum is important in coordinating voluntary movements.

Match these brain structures, labelled a. through e., with their associated descriptions. (Options may be used more than once or not at all.) a.cerebellum b.hypothalamus c.brain stem d.basal nuclei e.cerebral cortex -damage to this structure is associated with a resting tremor

Which statement does NOT correctly describe the brain stem?

Match the following structures, labelled a. through f., to their descriptions. a.dorsal horn b.dorsal root c.dorsal root ganglion d.ventral horn e.ventral root f.lateral horn -Afferent fibres enter the spinal cord through this structure.

A central bundle of interneuronal axons is called a tract, whereas a peripheral bundle of afferent and efferent neuronal axons is called a nerve.
