Which of the following statements about concussion is true? aA concussion is a type of traumatic brain injury. bIt is safe for a person who may have a concussion to immediately resume whatever activity they were doing when the injury occurred. cA person must have to be hit with a great deal of force to sustain a concussion. dA person with a concussion will always lose consciousness briefly.

What is the main idea of this text?Concussions are a serious problem for young people playing sports, and coaches and teams are adjusting policies to better protect players.NFL players Andrew Luck and Rob Gronkowski both quit football before the age of 30 because they were concerned about concussions.Concussions can cause a variety of symptoms, including headaches, memory loss, dizziness, and vision difficulties.Traumatic brain injury is a serious problem for athletes, but doctors don’t know enough about it to correctly diagnose it.

A 54-year-old female with symptoms of persistent fatigue and impaired cognitive function was examined by her physician.  During the exam, the patient expressed concern over increased body fat and, under questioning, reported having suffered a concussion during a soccer match in college.  Based upon the patient's symptoms and responses to questions, the physician ordered a panel of tests.A concussion is a mild traumatic brain injury (TBI) that results from impact to the skull.  TBI occurs most frequently in male patients, typically due to accidents; however, there is growing appreciation that TBI also occurs in male and female athletes during sporting events.  In addition, previously unrecognized chronic responses to TBI (eg, hormonal deficiencies) are now better understood.As part of the examination, the patient underwent a test to evaluate growth hormone (GH) secretion.  The brain participates in regulating GH secretion, and roughly half of the GH secreted into the blood is bound to a binding protein that increases the half-life of GH by inhibiting its urinary elimination.  Furthermore, lipid-soluble sex hormones, such as estradiol, augment GH secretion.During the GH secretion test, GH-releasing hormone (GHRH) was administered to the patient along with arginine.  GHRH is an endogenous stimulator of GH secretion, and arginine inhibits secretion of somatostatin, an endogenous inhibitor of GH secretion.  When administered together in healthy individuals, GHRH and arginine strongly stimulate GH secretion into the blood.  However, this patient exhibited an abnormally small response to GHRH and arginine, leading the physician to start the patient on GH therapy.  After a year, the patient's symptoms had improved, and body composition testing showed that her lean body mass had increased. Question 36Based on the passage, a likely mechanism by which GH therapy relieves chronic symptoms associated with TBI is by:A.stimulating protein synthesis in multiple tissues.B.inhibiting protein synthesis in multiple tissues.C.stimulating GHRH release by the pituitary.D.inhibiting GHRH release by the pituitary.

Who can determine if a student-athlete might have sustained a concussion during practice or competition? A coach A physician All answers are correct A licensed health care professional

4Why are many people so worried about concussions in student athletes?because younger people are less concerned about their brainsbecause younger people are more vulnerable to concussionsbecause student athletes can’t perform well in school with a concussionbecause younger people’s brains are being affected by technology
