Final answer:
Jerry, being seventy years old, should not expect regeneration of worn, damaged nervous tissues such as those in the brain and spinal cord, due to the minimal regenerative capacity of these tissues as one ages.
Step-by-step explanation:
As individuals age, the body undergoes various changes that affect its ability to regenerate tissues. In a seventy-year-old individual such as Jerry, the capability for certain tissues to repair themselves diminishes significantly. Notably, muscles and nervous tissue do not regenerate effectively in older adults. Muscles atrophy and may be replaced by connective tissue, resulting in a loss of contractile function. Nervous tissue, including that found in the brain and spinal cord, exhibits minimal regenerative capacity, which can lead to lasting damage after injury. While skin and some organs show a reduced but continued ability to heal, bones can heal but become more brittle and prone to fractures with advancing age.
Given these aspects of aging, Jerry should not expect the regeneration of worn, damaged nervous tissues, leading to diminished healing abilities and potential for permanent deficits. Therefore, the correct answer is that Jerry should NOT expect regeneration of worn, damaged nervous tissues.
