What is NOT true of embryonic neuron formation? Neuron formation begins in the spinal cord. 3. What terms means "below" when referring to the human brain? inferior 4. A _______ section through the spinal cord is parallel to the ground, and a _______ section made through the human brain and is parallel to the ground transverse; horizontal 5. Assume that electrical stimulation of the right motor cortex elicits arm movements on the left side of the body. In this instance, we would describe this as a(n) _______ organization of the motor cortex and the muscles of the body. contralateral 6. Neurons within the cortex are arranged in columns in part because cells within the column travelled along the same radial glial fiber. 7. What is FALSE of the evolution of the human brain? The human brain is smaller than that of any other primate. 8. What is true of embryonic neuron formation? A progenitor cell forms a neuron and another founder cell during asymmetrical division. 9. What is true of the human cerebral cortex? The human cortex is about 3 mm in thickness. 10. What is comprised of the pons and the cerebellum? metencephalon 11. What is an argument that supports the idea that experiences can modify brain development? The development of the neural circuits for depth perception require input from both eyes during a critical period. 12. Neurons that are formed during embryonic development are likely to die if they are unable to form synaptic contacts with other neurons. 13. You have just become a neurologist. (Congratulations!) Your first patient is partially paralyzed on the left side of his body. You might suspect that he has suffered damage to what area of the cerebral cortex? the right frontal lobe 14.

What is a result of a stoppage of CSF flow? hydrocephalus 16. CSF is reabsorbed into the blood supply via the arachnoid granulations. 17. Postganglionic sympathetic fibers secrete the neurotransmitter _________, while preganglionic sympathetic fibers secrete _________. norepinephrine; acetylcholine 18. Control of ______________ is a function of the autonomic nervous system "vegetative" processes 19. The _______ make up the autonomic nervous system. sympathetic and parasympathetic divisions 20. What is true regarding the functions performed by the left and right hemispheres? The left hemisphere is adept at the analysis of information. 21. The _______ region of cortex lies buried within a fissure between the _______ and the _______ lobes. insular; frontal; temporal 22. The motor association cortex is located just rostral to primary motor cortex. 23. What terms and shapes are not a correct match? fornix; "breast-­‐shaped" 24.

Axons that make up the _______ connect the mammillary bodies and the hippocampus. fornix 27. The midbrain is comprised of the tectum and tegmentum. 28. The spinal cord is contained within an aperture of the vertebrae called the spinal foramens. 29. An anesthetic drug injected near the dura around the cauda equina would deaden pain sensation in the pelvic region 30. What belongs together? oxytocin; stimulation of milk ejection from the breast 31. The term "rostral" means toward the beak or snout. 32. In which view of the brain would one be able to observe a specific structure in both hemispheres? coronal 33.

Which brain region is NOT part of the limbic system? putamen 36. The four hollow and interconnected spaces within the brain form the ventricles. 37. The middle layer of the meninges is the arachnoid membrane 38. What is correct regarding CSF? Drainage of CSF would result in compression of brain tissue onto the ventral skull surface. 39. The _______ branch of the nervous system is under involuntary, unconscious control. autonomic 40. This type of neuron carries information toward the brain Afferent 41. A _______ refers to a small groove on the surface of the human cortex. sulcus 42. What most accurately describes the general functions performed by the left and right hemispheres?
