The right hemisphere is usually dominant in right-handed persons.

Information as to whether a finger was touching an ice cube or being hit by a hammer would be carried to the brain in different ascending tracts within the spinal cord.

Match the structure to its proper description. a.dorsal horn b.dorsal root c.dorsal root ganglion d.ventral horn e.ventral root f.lateral horn -Contains cell bodies of interneurons upon which afferent neurons terminate

Match the following lobes to its descriptions: a.occipital lobes b.temporal lobes c.parietal lobes d.frontal lobes -Responsible for personality traits

Match spinal tract with correct characteristic. a.lateral spinothalamic b.rubrospinal c.lateral corticospinal d.ventral spinothalamic e.ventral spinocerebellar -Conducts impulses that allow the brain to perceive pain and temperature

Which of the following statements about cerebrospinal fluid is incorrect?

Hydrocephalus is caused by insufficient cerebrospinal fluid.

Cells that normally protect the brain but may also be responsible for certain neurodegenerative diseases are

Which of the following does not participate in control of skeletal muscle activity?

What part of the brain plays a vital role in short-term memory involving the integration of various related stimuli and is also crucial for consolidation into long-term memory?

Skeletal muscles are stimulated by the ____________________ nervous system, which is within the ____________________ division of the peripheral nervous system.

Distinguish between how short-term memory is stored and how long-term memory is stored.

The initial storage of complex memory involving modifications that take place by increased use at a given preexisting synapses is called ____________________.

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

A chemical secreted from astrocytes that can trigger synapse formation is

The spinocerebellum enhances muscle tone and coordinates skilled movements, while the cerebrocerebellum is important in maintaining balance and controlling eye movements.

____________________ are tumors of the meninges.

Disorders of the cerebellum are characterized by a resting tremor.
