Question 1

If the athlete has fallen on the field and a neck or spine injury is suspected, have the athlete lie there moving his extremities slowly.

Accepted Answer

If a neck or spine injury is suspected, it is important to keep the athlete still and call for medical help immediately. Moving the extremities could make the injury worse.

Question 2

The vagus nerve, cranial nerve ____, is responsible for activities involving the throat and for regulating the heart rate; it also affects the smooth muscle of the digestive tract.

Accepted Answer

The vagus nerve is the 10th cranial nerve and is responsible for controlling many important bodily functions, including regulating heart rate, breathing, and digestion. It also plays a role in the parasympathetic nervous system, which is responsible for the body's rest and digest response.

Question 3

____ vertebrae are associated with the lower back.

Accepted Answer

The five lumbar vertebrae are located in the lower back, between the thoracic vertebrae (which are associated with the chest) and the sacral vertebrae (which are part of the pelvis). The cervical vertebrae are in the neck, and the coccygeal vertebrae are at the base of the spine.

Question 4

There are approximately 1 ____ neurons in a human spinal cord.

Accepted Answer

The answer of There are approximately 1 ____ neurons in...

Question 5

An athlete with a compression fracture will usually not be able to move around or walk.

Accepted Answer

While a compression fracture can be extremely painful and limit movement, athletes with this injury may still be able to walk or move around. It depends on the severity of the fracture and the individual's pain tolerance. However, it is important to seek medical attention if a compression fracture is suspected, as further damage can occur if left untreated.

Question 6

____ is narrowing of the spine.

Accepted Answer

Stenosis is the narrowing of the spine, which can compress the spinal cord or nerve roots and cause symptoms such as pain or weakness. Neuropraxia refers to a reversible injury to a nerve, quadriparesis is weakness or paralysis of all four limbs, and paresthesia is an abnormal sensation such as numbness or tingling.

Question 7

A spinal cord contusion can cause swelling within the cord, resulting in various degrees of temporary or permanent damage.

Accepted Answer

A spinal cord contusion can cause swelling within the cord, resulting in various degrees of temporary or permanent damage.

Question 8

The first rule of management for an athlete who is on the field with a neck injury is to stabilize the neck.

Accepted Answer

Stabilizing the neck is crucial in preventing further injury to the spinal cord or vertebrae in cases of suspected or confirmed neck injuries in athletes on the field.

Question 9

The parasympathetic nerves are not strongly influenced by emotion.

Accepted Answer

The parasympathetic nerves can be influenced by emotions such as relaxation, pleasure, and contentment, which can activate the "rest and digest" response.

Question 10

It is estimated that ____% of neurologic injuries are created after the initial traumatic event.

Accepted Answer

Approximately 50% of neurologic injuries occur after the initial traumatic event due to secondary injury mechanisms such as swelling, bleeding, and inflammation.

Question 11

____ is a defect in the pars interarticularis of the vertebrae.

Accepted Answer

Spondylolysis is a defect in the pars interarticularis, which is a small section of bone located between the facet joints in the back of the vertebrae. Disk herniation refers to a condition in which the spongy disk between the vertebrae ruptures or bulges, leading to nerve compression and pain. Contusion refers to a bruise or injury to a muscle, bone, or other internal tissue. Neuropraxia is a nerve injury resulting in temporary loss of function.

Question 12

Intervertebral herniated disks should be treated by a physician.

Accepted Answer

Intervertebral herniated disks require medical attention and treatment by a physician. Self-treatment can potentially worsen the condition and lead to further injury.

Question 13

The functions of the peripheral nervous system include which of the following?

Accepted Answer

The peripheral nervous system includes sensory receptors, nerves, and ganglia outside of the brain and spinal cord. One of its functions is to act as the reflex center of the body, which allows for quick, automatic responses to stimuli without involving the brain. It does not limit electrical impulses or prevent involuntary actions, nor does it separate the body from the central nervous system (which is actually interconnected with the peripheral nervous system).

Question 14

The cranial nerves are ____ nerve pairs that begin in areas of the brain.

Accepted Answer

The cranial nerves are 12 nerve pairs that originate in specific areas of the brain and mainly control sensory and motor functions of the head and neck.

Question 15

Cervical vertebrae are located in the chest area.

Accepted Answer

Cervical vertebrae are located in the neck area, not the chest area.

Question 16

The sympathetic nervous system is often referred to as the "____ system."

Accepted Answer

The sympathetic nervous system is often referred to as the "fight or flight" system because it prepares the body for rapid physical activity in response to a perceived threat or danger. This response includes an increase in heart rate and breathing rate, dilation of pupils, and increased blood flow to muscles.

Question 17

The cranial and spinal nerves make up half of the peripheral nervous system.

Accepted Answer

The cranial and spinal nerves together make up the entire peripheral nervous system, not just half of it.

Question 18

The nervous system is the body's information gatherer, storage center, and control system.

Accepted Answer

This is a true statement. The nervous system is responsible for receiving sensory input from the environment, processing and storing that information, and then coordinating the body's response to that stimuli. It is considered the body's control system because it regulates and controls all bodily functions, such as movement, sensation, and thought.

Question 19

There are no neurologic signs of a sacroiliac sprain.

Accepted Answer

A sacroiliac sprain typically causes pain and discomfort in the lower back and buttocks but does not typically result in any neurologic signs or symptoms. Neurologic signs would suggest a more serious underlying condition.

Question 20

Like the brain, the spinal cord is submerged in cerebrospinal fluid and is surrounded by the ____ meninges (membranes).

Accepted Answer

The spinal cord is surrounded by three layers of protective meninges: dura mater, arachnoid mater, and pia mater.

Quiz 24: The Spine
