1) The reticular activating system at the core of the brainstem modulates cycles forest and activity by
A. Conducting motor commands from the brain to the body
B. Coordinating muscle activity and maintaining balance
C. Monitoring incoming sensory information, and promoting
wakefulness or allowing sleep in higher brain regions.
D. Balancing incoming sensory information with
physiological functions.
E. Tracking hormone levels in the bloodstream
2.Which of the following statements about BPG is false?
A. It results from metabolism of glucose
B. Its production increases with altitude
C. Its production increases with exercise
D. It stands for 2,3-bisphosphoglyceric acid
E. It causes a left-shifted O2-binding/dissociation curve
in adult hemoglobin.
3.The spinal cord
A. communicates information between the brain and the rest of the body
B. processes and integrates much information
C. can issues some commands to the body with input from the brain
D. develops from a hollow dorsal neural tube
E. All of the above
4. Evolutionary change has resulted in the brains of some vertebrate species being larger than would be predicted by their body size. The
larger brain size is mostly due to an increase in surface are and is made possible by the convolutions of the cerebral cortex. This
contributes primarily to
A. increased intellectual ability
B. increased running ability
C. decreased energy needs
D. less association cortex
E. a larger brainstem
