Question 1

Meningiomas typically arise from

Accepted Answer

Meningiomas arise from the meninges, which are the membranes covering the brain.

Question 2

Tumors in the nervous system arise from

Accepted Answer

Tumors in the nervous system typically arise from glial cells and the meninges, as neurons generally do not divide and thus are less likely to form tumors.

Question 3

Which of the following individuals is the most likely to have chronic traumatic brain injury (CTBI)?

Accepted Answer

Contact sports such as soccer are associated with higher risk for head injury and CTBI compared to other sports like sprinting or swimming. Ballet dancing does not involve contact with other individuals, so the risk for head injury is lower.

Question 4

Symptoms of tumors include

Accepted Answer

Tumors can cause general symptoms such as increased pressure and specific symptoms related to the location of the tumor. Increased heart rate and increased amounts of cerebrospinal fluid are not necessarily symptoms of tumors. Loss of the ability to plan behavior is a symptom that may be specific to a tumor in certain parts of the brain.

Question 5

Gliomas typically arise from

Accepted Answer

Gliomas are tumors that originate from glial cells, which include astrocytes and oligodendrocytes. Neurons, Schwann cells, and the membranes covering the brain do not give rise to gliomas.

Question 6

Tumors that lack boundaries and are likely to recur following removal are known as

Accepted Answer

Tumors that lack boundaries and are likely to invade and recur following removal are known as infiltrating or malignant tumors. Encapsulated tumors, on the other hand, have distinct boundaries and are more likely to be benign.

Question 7

Tumors with distinct boundaries that are unlikely to recur following removal are known as

Accepted Answer

Tumors that have distinct boundaries and are unlikely to recur following removal are often encapsulated, meaning they are surrounded by a capsule or wall of fibrous tissue that separates them from the surrounding tissue. Encapsulated tumors are more likely to be benign, as they are usually contained and do not invade neighboring tissue. Therefore, choice C is the best choice.

Question 8

Thalidomide may be useful in treating tumors due to its ability to

Accepted Answer

Thalidomide has been shown to be effective in reducing the blood supply (angiogenesis) used by tumors, which hinders tumor growth and survival. It does not directly destroy tumor cells or prevent metastasis, nor does it promote encapsulation.

Question 9

Meningiomas typically

Accepted Answer

Meningiomas are typically slow-growing tumors that arise from the meninges, the protective membranes surrounding the brain and spinal cord. They are usually benign and confined to the surface of the brain, making them more easily surgically removed. Meningiomas are rare malignant, and they have a low risk of metastasizing to other organs.

Question 10

The best predictor of the development of chronic traumatic brain injury (CTBI)in boxers is

Accepted Answer

The best predictor of the development of CTBI in boxers is their genetic makeup. Studies have shown that certain genetic variants may increase susceptibility to brain injury and worsen outcomes, such as chronic traumatic encephalopathy (CTE). Protective headgear and weight class may decrease the risk of acute injuries, but do not necessarily prevent the long-term effects of repetitive head trauma. Win-loss records do not have a direct correlation with the development of CTBI.

Question 11

Your physician soberly informs you that you have been diagnosed with a Grade I tumor and will require surgery.What does this mean?

Accepted Answer

Grade I tumors are usually benign and respond well to surgery, so the chances of survival are relatively good. Options A and B are incorrect as Grade I tumors are not rapidly fatal and require removal through surgery, respectively. Option C is partially correct but does not provide a full understanding of the situation as it implies the tumors tend to recur, but it does not suggest that recurrence is associated with adverse outcomes.

Question 12

The use of chemotherapy for brain tumors is complicated by the fact that

Accepted Answer

The blood-brain barrier is a protective mechanism that prevents many substances from entering the brain. Therefore, many substances used in traditional chemotherapy cannot cross the blood-brain barrier and reach the brain tumor. However, there are some drugs that can pass through the barrier and are used in chemotherapy for certain types of brain tumors.

Question 13

Symptoms of chronic traumatic brain injury (CTBI)include

Accepted Answer

Chronic traumatic brain injury (CTBI) can cause slurred speech and personality changes as the brain is permanently damaged. Inability to feel pain and unrealistic euphoric mood may be a symptom of other conditions, not specific to CTBI. High blood pressure may also be caused by various factors and is not a specific symptom of CTBI.

Question 14

Independent growths of new tissue that lack purpose are known as

Accepted Answer

Tumors are independent growths of new tissue that lack purpose, whereas the other options involve abnormalities or malformations of existing blood vessels or structures.

Question 15

Which of the following could not be an accurate statement?

Accepted Answer

A benign tumor cannot spread to other parts of the body, so the statement that Tom has a benign tumor that has spread to his liver is not accurate.

Question 18

In a study of concussions occurring in the National Football League (NFL),losing consciousness for more than one minute was highly correlated with the athlete's needing more than a week of rest to recover.From this,we can infer that

Accepted Answer

The answer of In a study of concussions occurring in...

Question 19

The process in which tumors shed cells that travel to another part of the body,where they initiate new tumor growth,is known as:

Accepted Answer

Metastasis is the process in which cancer cells detach from the primary tumor and travel to other parts of the body, where they initiate the growth of new tumors. Infiltration refers to the spread of cancer cells into the surrounding tissues, while encapsulation refers to the formation of a capsule around a tumor. Malformation is not a term commonly used in relation to cancer growth and spreading.

Question 20

Following a concussion,an athlete should

Accepted Answer

The American Academy of Neurology has specific criteria for when an athlete can safely return to play after a concussion. These criteria include being symptom-free, having normal neurological exam and balance testing, and completing a graduated exercise program. It is important to follow these guidelines to ensure the athlete's safety and prevent further injury.
