Question

one of the last areas of the cns to mature is the hypothalamus, which contains centers for regulating body temperature. for this reason, premature babies usually have problems (1. ) their loss of body heat and must be carefully monitored. the nervous system grows and matures all through childhood, largely as a result of myelination that goes on during this period. a good indication of the degree of myelination of particular neural ( 2. ) is the level of neuromuscular control in that body area. neuromuscular coordination progresses in a superior to inferior direction and in a proximal to distal direction, and ( 3. ) occurs in the same sequence (as described in chapter 6).
the brain reaches its maximum weight in the young adult. over the next 60 years or so, neurons are (4. ) and die, and brain weight and volume steadily decline. however, a nearly unlimited number of neural pathways is always available and ready to be (5. ), allowing us to continue to learn throughout life.

5. pathways 2. myelination 3. damaged 4. developed 5. controlling

Explanation:

• For the first blank, "controlling" makes sense as premature babies need to manage (control) heat loss.
• "Pathways" fits the second blank as we are talking about neural pathways.
• "Myelination" occurs in the same sequence as neuromuscular coordination (superior - inferior, proximal - distal).
• Neurons get "damaged" over time (as they die).
• Neural pathways are "developed" to allow learning.
