1.
Concussion
Correct Answer
C. Produced by pressure on the cord
Explanation
The correct answer suggests that a concussion is produced by pressure on the spinal cord. This means that the injury to the spinal cord is caused by external force or compression, leading to a disruption in the normal functioning of the cord. This pressure can result in the loss of sensory or motor function below the level of the injury. It is important to note that a concussion is different from bleeding or tearing in the spinal column, as mentioned in the other options.
2.
Contusion
Correct Answer
B. Bleeding in the spinal column
Explanation
The correct answer is bleeding in the spinal column. A contusion is a bruise, and in this context, it refers to an injury to the spinal cord caused by pressure. Bleeding in the spinal column can occur as a result of this injury and can further damage the spinal cord, leading to loss of sensory or motor function below the level of the injury. Direct injury may also cause bleeding in the spinal column, exacerbating the contusion.
3.
Which is not an indirect lesion?
Correct Answer
D. No sensory or motor function below level of lesion
Explanation
The absence of sensory or motor function below the level of the lesion is not an indirect lesion. This means that there is no loss of sensation or movement in areas of the body that are located below the site of the injury. Indirect lesions typically refer to conditions that affect the spinal cord, such as impingement, dislocation, compression, or contusion. Concussion, although not specifically mentioned as an indirect lesion, can also be considered as it refers to a temporary loss of brain function due to a head injury.
4.
Anterior longitudinal ligament stretched or ruptured, central cord injury, ligamentum flavum.
Correct Answer
B. Hyperextension
Explanation
The correct answer is hyperextension. Hyperextension refers to the excessive backward movement of a joint or body part beyond its normal range of motion. In the context of the given options, hyperextension can lead to the stretching or rupture of the anterior longitudinal ligament, which is a common injury in the spine. This can result in a central cord injury, where the spinal cord is damaged in the center, causing neurological deficits. Other options such as anterior cord syndrome, posterior cord syndrome, and flexion-rotation are not directly related to hyperextension.
5.
Which is not included in hyperflexion?
Correct Answer
D. Posterior cord syndrome
Explanation
Posterior cord syndrome is a condition that occurs when there is damage to the posterior spinal cord, resulting in loss of proprioception, vibration sense, and fine touch. Hyperflexion of the spine can cause compression and damage to the spinal cord, leading to various syndromes such as anterior cord syndrome or central cord syndrome. However, posterior cord syndrome is not typically associated with hyperflexion. Therefore, it is the option that is not included in hyperflexion.
6.
Spinal shock causes rigidity in the joints.
Correct Answer
B. False
Explanation
Spinal shock is a temporary condition that occurs immediately after a spinal cord injury. It is characterized by a loss of reflexes, muscle flaccidity, and decreased muscle tone, rather than rigidity in the joints. Therefore, the statement that spinal shock causes rigidity in the joints is false.
7.
What does not belong concerning spinal shock
Correct Answer
B. No loss of sensation below level of injury
Explanation
Spinal shock refers to a temporary loss of reflexes and muscle function that occurs immediately after a spinal cord injury. During this period, there may be a complete absence of reflexes and flaccidity (limpness) in the muscles below the level of injury. However, sensation may still be preserved, meaning that the person can still feel touch, pain, and temperature below the level of injury. The absence of loss of sensation below the level of injury is not characteristic of spinal shock.
8.
What is not true of cauda equina lesions
Correct Answer
A. Fractures or disloxcations below S1
Explanation
below L1
9.
Anterior cord syndrome - what is right
Correct Answer
E. Damage to anterior portion of cord
Explanation
Anterior cord syndrome is a condition characterized by damage to the anterior portion of the spinal cord. It is an extremely rare condition that typically results from a rupture of the posterior spinal ligament. The syndrome is associated with a wide steppage gait and affects motor cord function, as well as the sense of pain and light touch.
10.
Anterior cord syndrome - what is wrong
Correct Answer
E. Keep motor cord funciton sense of pain and light touch
Explanation
The correct answer is "damage to the anterior portion of the cord." In anterior cord syndrome, there is damage to the front portion of the spinal cord, specifically the anterior spinal artery. This can occur due to a flexion injury of the cervical spine. The result is a loss of motor function and sensation for pain and temperature, while preserving motor function and sense of light touch.
11.
Brown sequard - which one is wrong?
Correct Answer
C. Keep proprioception kinesthesia and vibratory sense on side of lesion
Explanation
The correct answer is "keep proprioception kinesthesia and vibratory sense on side of lesion." This answer is incorrect because in Brown-Sequard syndrome, there is a hemisection (half-section) of the spinal cord. This results in the loss of motor function, proprioception, and vibratory sense on the side of the lesion. Therefore, the correct statement would be that these senses are lost on the side of the lesion, not kept.
12.
Brown sequard syndrome presents itself with loss of pain and temperaturesensation on opposite side of lesion
Correct Answer
A. True
Explanation
Brown-Sequard syndrome is a neurological condition caused by damage to one half of the spinal cord. It typically results in a loss of pain and temperature sensation on the opposite side of the lesion, while preserving touch and proprioception. This is due to the crossing of sensory pathways in the spinal cord. Therefore, the given statement is true.
13.
In a flexion-rotation injury the lower vertebra is displaced under the vertebra above
Correct Answer
B. False
Explanation
upper most vertebrae displaced over vertebrae below
14.
Central cord syndrome - which is right
Correct Answer
B. Hyperextension
Explanation
Hyperextension refers to the excessive backward bending of a joint or body part. In the context of central cord syndrome, hyperextension can cause damage to the anterior portion of the spinal cord. This can occur when the neck or back is forcefully extended beyond its normal range of motion, leading to compression or injury to the spinal cord. The symptoms of central cord syndrome, such as a wide steppage gait, are consistent with the damage caused by hyperextension. Therefore, hyperextension is the most likely cause of central cord syndrome in this scenario.
15.
Posterior cord syndrome - which is wrong
Correct Answer
B. Common
Explanation
The given answer states that posterior cord syndrome is common. Posterior cord syndrome is a rare neurological condition caused by damage to the posterior spinal cord. It is characterized by the loss of proprioception below the level of injury, which refers to the body's ability to sense its position in space. Additionally, individuals with posterior cord syndrome may experience a wide-steppage gait and a loss of two-point discrimination below the level of injury. Therefore, the statement that posterior cord syndrome is common is incorrect.
16.
Sacral sparing - which is wrong
Correct Answer
D. Small amount of centrally located sacral trunk is spared
Explanation
The given answer suggests that in an incomplete cervical lesion, a small amount of the centrally located sacral trunk is spared. This means that despite the lesion, there is still some preservation of sensation in the saddle area. This is in contrast to a complete cervical lesion where there would be no sacral sparing and loss of sensation in the saddle area. Therefore, sacral sparing is considered a sign of an incomplete cervical lesion.
17.
Nerve roots can not regenerate
Correct Answer
B. False
Explanation
Nerve roots have the ability to regenerate to some extent. While they may not regenerate fully, they can undergo a process called neuroregeneration, where damaged nerve fibers can regrow and reconnect with the appropriate target cells. This process can be facilitated through various treatments and therapies. Therefore, the statement that nerve roots cannot regenerate is false.
18.
Root escape is the loss of function of nerve roots at or near level of lesion
Correct Answer
B. False
Explanation
The statement is incorrect. Root escape refers to the preservation of nerve root function despite the presence of a lesion at or near the level of the nerve root. Therefore, the correct answer is false.
19.
In an upper motor neuron lesion flaccidity develops
Correct Answer
B. False
Explanation
In an upper motor neuron lesion, flaccidity does not develop. Flaccidity refers to a lack of muscle tone and weakness, which is typically seen in lower motor neuron lesions. In upper motor neuron lesions, there is usually hypertonia (increased muscle tone) and spasticity due to the disruption of the descending motor pathways. Therefore, the statement "In an upper motor neuron lesion, flaccidity develops" is false.
20.
T9-T11 innervate the......
Correct Answer
C. Lower abdominals
Explanation
T9-T11 innervate the lower abdominals. This means that the nerves originating from the spinal levels T9, T10, and T11 are responsible for supplying the lower abdominal muscles with the necessary nerve signals for contraction and movement. The external intercostals are innervated by different nerves, while the upper abdominals are not specifically mentioned in relation to T9-T11 innervation. Therefore, the correct answer is lower abdominals.
21.
The spinal center for urination is in the conus medularis which is located S2-S4
Correct Answer
A. True
Explanation
The spinal center for urination is indeed located in the conus medullaris, which is found in the S2-S4 region of the spinal cord. This region contains the nerves responsible for controlling the bladder and coordinating the process of urination.
22.
Most quadriplegics die from poor blood circulation
Correct Answer
B. False
Explanation
lung complications or infection
23.
Lesions above S2-S4 cause a non-reflexive bladder and needs catheterization
Correct Answer
B. False
Explanation
The statement "lesions above S2-S4 cause a non-reflexive bladder and needs catheterization" is false. Lesions above S2-S4 actually cause a reflexive bladder, meaning that the bladder can still empty itself without the need for catheterization.
24.
During spinal shock the bladder is contracted
Correct Answer
B. False
Explanation
During spinal shock, the bladder is actually flaccid or relaxed, not contracted. Spinal shock is a temporary condition that occurs after a spinal cord injury, where there is a loss of reflexes and sensation below the level of injury. This includes the loss of bladder control and the inability to empty the bladder voluntarily. As a result, the bladder becomes flaccid and overfills with urine, leading to urinary retention. Therefore, the correct answer is false.
