Final answer:
Feeling nervous is common for university freshers due to the natural stress response of the nervous system. While transient nervousness is typical, persistent or severe anxiety may indicate a nervous system disorder which affects millions and is the focus of ongoing research for better prevention and treatment.
Step-by-step explanation:
The statement that feelings of nerves are common to all university freshers can be considered true since it's very typical for new students to experience some level of nervousness upon entering university. This response to a new and potentially challenging environment is part of the natural human stress response, which involves the nervous system. The nervous system helps us move when needed, ensures that memories are formed and stored and that emotions are well regulated. While most individuals experience transient nervousness, others may have more significant reactions that can interfere with daily life. It's important to recognize that while nerves are common, extreme or persistent anxiety could be indicative of a nervous system disorder, a situation that affects millions annually in the United States. Researchers are continuously working to find better ways to prevent and treat nervous system disorders.
