Here are the answers
Ans.1:The correct answer is C.
This is a classic presentation of a patient with carpal tunnel syndrome, which typically affects females between the ages of 40 and 60 who chronically perform repetitive tasks that involve movement of the structures that pass through the carpal tunnel. One important structure that passes through the carpal tunnel is the median nerve. Patients often note a tingling, a loss of sensation, or diminished sensation in the digits. There is also often a loss of coordination and strength in the thumb, because the median nerve also sends fibers to the abductor pollicis brevis, flexor pollicis brevis, and the opponens pollicis. A final function of the median nerve distal to the carpal tunnel is control of the first and second lumbricals which function to flex digits two and three at the metacarpophalangeal joints and extend interphalangeal joints of the same digits.
Abduction of the fifth digit (choice A) is a function controlled by the ulnar nerve, which does not pass through the carpal tunnel.
Adduction of the thumb (choice B) is a function of the adductor pollicis, which is the only short thumb muscle that is not innervated by the median nerve, but rather by the deep branch of the ulnar nerve.
Sensation of the lateral half of the dorsum of the hand (choice D) is mediated by the radial nerve, which also does not pass through the carpal tunnel.
Sensation over the lateral aspect of the palm (choice E) is mediated by the median nerve, however the branch innervating the palm (palmar cutaneous branch of the median nerve) passes superficial to the carpal tunnel.
Sensation over the medial aspect of the dorsum of the hand (choice F) is mediated by the ulnar nerve.
Sensation over the medial aspect of the palm (choice G) is mediated by the ulnar nerve.
Ans 2:The correct answer is D.
The smooth part of the right atrium (the sinus venarum) is derived from the sinus venosus. The coronary sinus and the oblique vein of the left atrium also derive from the sinus venosus.
The bulbus cordis (choice A) gives rise to the smooth part of the right ventricle (conus arteriosus) and the smooth part of the left ventricle (aortic vestibule).
The primitive atrium (choice B) gives rise to the trabeculated part of the right and left atria.
The primitive ventricle (choice C) gives rise to the trabeculated part of the right and left ventricles.
The truncus arteriosus (choice E) gives rise to the proximal part of the aorta and the proximal part of the pulmonary artery.
Ans. 3 :The correct answer is A.
Chronic lymphocytic leukemia (CLL) is typically a disease of the elderly, with 90% of cases occurring after the age of 50; the median age is 65. Patients will typically present with a complaint of chronic fatigue and/or lymphadenopathy. Approximately 50% of all patients with CLL present with an enlarged liver and/or spleen. CLL typically pursues an indolent course but can occasionally present as a rapidly progressive disease. The hallmark of CLL is the isolated lymphocytosis in which the white blood cell count is usually greater than 20,000/mL and between 75% and 98% of the circulating cells are small "mature" lymphocytes. Chlorambucil is classified as a nitrogen mustard, a subcategory of the alkylating agents. It is primarily used to treat chronic lymphocytic leukemia and ovarian carcinoma; it can also be used to treat Hodgkin's disease and various other lymphomas.
Cisplatin (choice B) is an alkylating agent indicated for the treatment of metastatic testicular and ovarian tumors in combination with other agents.
Dacarbazine (choice C) is a cytotoxic agent with alkylating properties. It is used as a single agent or in combination with other antineoplastics in the treatment of metastatic malignant melanoma, refractory Hodgkin's disease, and various sarcomas.
Tamoxifen (choice D) is an antiestrogen hormone used in the palliative treatment of breast cancer in patients with estrogen-receptor-positive breast cancer.
Vinblastine (choice E) is a mitotic inhibitor antineoplastic agent indicated for the treatment of Hodgkin's disease and non-Hodgkin's lymphomas, choriocarcinoma, lymphosarcoma, and neuroblastoma, as well as various other types of cancer.
Ans. 4 :The correct answer is E.
The mediastinum is divided into four regions. The region above the manubriosternal junction (level of fourth thoracic vertebra) is the superior mediastinum. The region below the manubriosternal junction is divided into the anterior mediastinum (anterior to the pericardium), the middle mediastinum (within the pericardium), and the posterior mediastinum (posterior to the pericardium). The thoracic duct enters the thorax through the aortic hiatus of the diaphragm. At this point it lies in the posterior mediastinum, the region posterior to the pericardium. As it ascends through the thorax and passes the level of the fourth thoracic vertebra, it enters the superior mediastinum.
The anterior mediastinum (choices A and B) contains the thymus and fatty connective tissue.
The middle mediastinum (choices A, C, and D) contains the heart and the roots of the great vessels.
In addition to the thoracic duct, the superior mediastinum (choices B, D, and E) contains the ascending aorta, aortic arch, branches of the aortic arch, descending aorta, superior vena cava, brachiocephalic veins, thymus, trachea and esophagus.
In addition to the thoracic duct, the posterior mediastinum (choices C and E) contains the descending aorta, azygos vein, hemiazygos vein and the esophagus
Ans 5: The correct answer is C.
This is deja vu ("seen before"), which is the experience of an event, person, or thing as familiar, even though it has never previously been experienced. Severe cases often accompany an underlying neurologic problem.
Anterograde amnesia (choice A) is the inability to learn new facts. Most commonly, it involves both verbal and nonverbal material, but it can involve one or the other.
In confabulation (choice B), a patient reports "memories" of events that did not take place at the time in question.
In jamais vu (choice D), a patient fails to recognize familiar events that have been encountered before.
In retrograde amnesia (choice E), a patient fails to remember facts or events that occurred before the onset of amnesia.

ok buddies here are 5 questions from QBank unanswered....
1.1 .An increase in which of the following best explains the mechanism
by which the cardiac output increases in severe anemia?
A. Arteriolar diameter
B. Blood viscosity
C. Peripheral vascular resistance
D. Splanchnic blood flow
E. Tissue oxygen tension
2.An 80-year-old woman dies after a long history of progressive memory loss,
apraxia, and recurrent episodes of confusion. In the last months of life she
was bedridden and unable to recognize familiar faces and objects. The
pathologist identifies numerous flame-shaped intracytoplasmic inclusions
in neurons of the neocortex and hippocampus. These consist of paired
helical filaments (PHFs) on electron microscopy. Which of the following
biochemical changes most likely accounts for the development of PHFs in
this condition?
A. Abnormal degradation of amyloid precursor protein (APP)
B. Abnormal phosphorylation of tau
C. Accumulation of advanced glycosylation end (AGE) products
D. Increased expression of APP
E. Precipitation of insoluble a-tubulin
3.A 71-year-old man has been in excellent health, and practicing
competently as an attorney. He is brought to the emergency room
following a motor vehicle accident. A workup, including imaging of
the spine, thorax, and head, is negative, but the patient is admitted
for overnight observation. His injuries include several lacerations to
the face and extremities as well as several contusions to the thorax.
Three weeks later, he is admitted to the hospital for confusion.
A neurologic exam is normal except that he is not oriented to time
or place, and can recall only 1 out of 6 objects after 3 minutes.
Which of the following is the most likely diagnosis?
A. Alzheimer's disease
B. Brain metastases
C. Epidural hematoma
D. Normal pressure hydrocephalus
E. Subdural hematoma
4.A 36-year-old female is brought to the emergency room by her
husband who says that she "complained of a severe headache then lost
consciousness." She has a history of hypertension and had been on several
different medications. The examining physician notes that she is unable
to move her arms and legs, but can blink her eyes. When the physician asks
her to blink twice if she can hear him, she promptly does so. In which of
the following structures is this woman's lesion most likely located?
A. Cervical spinal cord
B. Medulla oblongata
C. Midbrain
D. Pons
E. Thalamus
5.A 45-year-old man presents to the emergency department with severe
headache and vomiting. A CT scan shows a well-circumscribed cystic lesion
within the 3rd ventricle; there is no calcium deposition. The cyst is
surgically removed. On histologic examination, the wall of the cyst
consists of a single layer of mucin-producing columnar epithelium with
a ciliated apical surface. Which of the following is the most likely
diagnosis?
A. Colloid cyst
B. Craniopharyngioma
C. Cysticercosis
D. Echinococcus cyst
E. Pilocytic astrocytoma
NB-->with atleast one line explanation to ur choosen ans....they are easy...lets finish qbank's unans questions this way...

Keepgoing , you chose almost every q from NA . I have not read NA yet . Well I will be guessing on all except the first one
1: A , as arteriolar diameter increases and leads to increased CO in severe anemia.
2: B Wild guess
3: E , cannot be Elzeimer's or metastasis . Epidural hemarrhage is usually acute and more severe as it is arterial bleeding. Not sure between D and E but choose E.
4: D again a guess
5: A , B is found in the pituatiry ,C is multiple cysts, D is not found in the brain , have no idea about E .

Thanks Keepgoing. I will hide that bucket of candies from my kids and will eat all the candies myself
As we do not have answers for these qs, why don't you also give your answers and a little bit of explanation too. It will help me understand things better. I hope others will also try after the weekend.

Which gandaa sa subject is this? i think CNS patho Ok.. i can't answer all of them accurately n confidently but i ll try on the basis of my limited knowledge frm neuroanat n what i cn recollect frm medicine.
1-Dunno.. A or D .. ok D..bcoz i know its due to inc in preload.. but will be able to say clearly when i hv done CVS physio.
2- Dunno again.. Tukka is A .. coz i think its alzheimer's
3- D Normal pressure hydrocephalus presents with very slowly progressing dementia
4- B Bilateral Lesion below cochlear nuclei..probably medulla .. Q not well designed.. vagus should have been tested.
5- A Age+symptoms of hydrocephalus+location r classic.

okay.. so nnl, focus, mytime n i discussed these qs in detail.. n this is what we arrived at..
1- A as everyone's agreeing

3- E small leak of emmisary vein presents as chronic subdural hematoma
4- B ok.. mytime n focus don't agree wth us but nnl n i have discussed this at length n are preeeeettyyyyy sure its medulla.. can't explain here though.. its too long n won't make sense anyway
5- A Classic presentation.. again as everyone agrees..
