That of the following neuroanatomical websites is almost certainly resulting in her symptoms? A. Right C5 nerve root B. Right C6 nerve root C. Right C7 nerve root D. Right radial nerve

16. A thirty two year old previously healthy male provides to the clinic of yours with trouble walking, progressive for many seasons. His examination shows natural sensation (no sensory level) as well as weakness of both reduced extremities (distally and proximally). His upper extremity strength and also reflexes are normal. He's hyperreflexia in his ankles and patella. His feet are upgoing on plantar effect. His overall tone is increased. He denies any urinary or perhaps bowel symptoms.

He reports tingling and pain which radiates down the best posterior thigh, posterolateral patent, along with lateral foot. Examination reveals natural strength except for mild correct plantar flexion plus toe flexion weakness. Reflexes are standard except for lacking right ankle jerk. Sensory examination is typical to most modalities despite subjective sensory signs. That of the following neuroanatomical places is likely leading to the patient's symptoms? A. Right S1 nerve root B. Right L5 nerve root C. Right L4 nerve root D. Right Lumbar plexopathy

18. A thirty one year old previously healthy female presents with three times of sore damage of perspective in one eye. Her fundoscopic examination is usual bilaterally. On gentle examination of the pupils of her, the left eye of her responds normally to light. Upon swinging the penlight to the correct eye, her pupil dilates. On recurring examination, these findings are reproducible. Or else, her cranial nerve, motor, sensory, reflexes along with cerebellar examination are typical. That of the following is regarded as the probable reason for her symptoms? A. Demyelinating plaque in her left occipital lobe B. Demyelinating plaque in her best occipital lobe C.

Sensory examination reveals decreased sensation in the 5th digit plus fifty percent the fourth digit, in addition to the medial forearm. That of the following is probably the most probable neuroanatomic place of the individual 's symptoms? A. Ulnar nerve at the elbow B. Ulnar nerve at the wrist C. Posterior cord of the brachial plexus D. Lower trunk of the brachial plexus

20. A thirty eight year old male provided with a best carotid artery dissection observing a handful of days of neck popping. He offered with correct MCA stroke on admission, which includes remaining sensory loss and hemiparesis. He's on anticoagulation. On the next clinic day, he's mentioned to enjoy a neurologic modification with a dilated right pupil on examination. That of the following is the probable etiology of his signs? A. Increased ICP due his big right MCA stroke resulting in papilledema on his best optic nerve. B. Embolic infarct triggering best ophthalmic artery occlusion along with his brand new examination findings. C. Increased edema of his proper MCA ischemic stroke leading to uncal herniation and stress on his ipsilateral right CN III. D. He might have had widespread dissections that have been missed on admission resulting in his innovative neurologic findings."

Question 15: Neuroanatomical location of Symptoms

 A woman aged 40 years with rheumatoid arthritis complains of neck pain with radiation to the right middle finger. On evaluation, there is weakness in the triceps, finger extensors and pronation There is absent right triceps reflex, impaired sensation of the right middle finger,σίας. The flows of current through the neural networks yield measured estimates of when and where the neuroanatomy for each symptom is most likely located.

 Answer: C Right C7 nerve root

 Rationale: Some of the passenger side symptoms probed and established to be associated with C7 nerve root include triceps weakness, finger extensors weakness, and decreased sensation in the right middle finger. C7 nerve root contains the motor and sensory fibers that innervate the triceps, finger extensors, and the skin region in the middle finger. C6 nerve root is innervating the thumb and forearm; C8 nerve root innervating the little finger and intrinsic muscles of the hand. The Radial nerve may also be in contention, however the types of sensory and motor loss is better characteristic of the C7 nerve root (Wipperman & Goerl, 2016).

 Question 16: What will be the next diagnostic done on a patient?

 A thirty-two-year-old male who presented with difficulty in walking, weakness of both lower limbs, bilateral hyper reflexia and up going plantar response, but MRI cervical, lumbosacral and thoracic were normal. What is the second best diagnostic action?

 Answer: D. Lumbar puncture

 Rationale: Since this patient present with neuro symptoms pointing towards CNS involvement with upper motor neuron signs and normal MRI, lumbar puncture is helpful in evaluating for condition such as multiple sclerosis or other inflammatory condition which may not be detected in MRI but can be detected in CSF analysis (Bradley, 2018).

 Question 17: The Neuroanatomical Target for Back Pain and Radiating Signs

 Patient 5 is a 49 Year Male having the following symptoms – Low back pain, tingling and pain in the posterior thigh and lateral foot, mild weakness of plantar flexion and no right ankle jerk was elicited. Where, then, is the likely location in his brain that is eliciting the symptoms?

 Answer: A. Right S1 nerve root

 Rationale: The symptoms such as the pain that goes down the posterior thigh and the lateral foot and reduced capacity to flex the foot, pointing the toes backward and no reflex ankle jerk suggests that S1 nerve root is involved. This nerve root deals with the actions on the posterior and lateral aspect of the leg in addition to involvement in the ankle reflex (Noble et al. , 2017).

 Question Page 18: Likely Reason for Pupil Response

 A thirty-one-year-old female with a complaint of sore vision in the left eye; fundoscopic appearance normal; the right pupil dilated when the light is swung from the left eye. What is the likely explanation of her manifestations?

 Answer: C. Demyelinating plaque in her right optic nerve ||

|| Possible Diagnosis | 1. Multiple Sclerosis | 2. Neuromyelitis Optica |

 Rationale: The results link to Marcus Gunn pupil with impaired afferent pathway of the right eye because of the demyelinating plaque in the optic nerve at the right side. These findings are in accord with optic neuritis that is related to multiple sclerosis which is well described by Beck et al. , (2019).

 Weakness of hand: Neuroanatomic Site for Hand Weakness

 A young female with weakness, pain and numbness in the right hand, with atrophy and weakness of abductor digiti minimi and other intrinsic muscles. Where would one predict her symptoms to originate from?

 Answer: A. Ulnar nerve at elbow

 Rationale: Weakness as well as atrophy of the intrinsic muscles of the hand and sensory loss in the fifth finger and half of the fourth finger suggest ulnar nerve injury which can occur at the elbow common to compression (Lazarus et al. , 2016).

 VKV  20 question: Neurologic changes occurring following Carotid artery dissection

 A man aged thirty-eight years presented with right MCA stroke due to carotid artery dissection, and latest Rolled with dilated right pupil. What is the most likely origin of such symptoms in his case?

 Answer: C. Progression of right MCA ischemic stroke related edema and development of uncal herniation with pressure on right CN III

 Rationale: From the right MCA stroke, edema occurs thus increasing intracranial pressure, and the development of a dilated pupil suggests uncal herniation. This herniation may compress the third cranial nerve – leading to pupillary dilation (Tzeng et al. , 2019).
