Ques:Answer the following question given this paragraph: White Columns Just as the gray matter is separated into horns, the white matter of the spinal cord is separated into columns. Ascending tracts of nervous system fibers in these columns carry sensory information up to the brain, whereas descending tracts carry motor commands from the brain. Looking at the spinal cord longitudinally, the columns extend along its length as continuous bands of white matter. Between the two posterior horns of gray matter are the posterior columns. Between the two anterior horns, and bounded by the axons of motor neurons emerging from that gray matter area, are the anterior columns. The white matter on either side of the spinal cord, between the posterior horn and the axons of the anterior horn neurons, are the lateral columns. The posterior columns are composed of axons of ascending tracts. The anterior and lateral columns are composed of many different groups of axons of both ascending and descending tractsthe latter carrying motor commands down from the brain to the spinal cord to control output to the periphery. Q: The brain is said to contain gray matter, while what related structure contains white matter separated into columns? Choices: - brain stem - amygdala - orbital lobe - spinal cord A:

Ans:spinal cord

Ques:Answer the following question given this paragraph: Other than infant reflexes, human behaviors are mainly learned rather than innate behaviors. Learned behavior is behavior that occurs only after experience or practice. Did you ever teach a dog to sit on command? That's an example of a learned behavior. The dog wasn't born knowing that it should sit when it hears the word sit. The dog had to learn the behavior. Q: What kind of behavior occurs only after experience or practice and describes most human behaviors? Choices: - innate behavior - inherited behavior - practiced behavior - learned behavior A:

Ans:
learned behavior
