1 touch receptors most numerous site in mucosa ?
a palate
b uvula
c tongue tip
d buccal vestibule
e attached gingiva

2 Developing heart is ?
a ant to prochordal plate
b post to prochordal plate
c due to notochord stimulation

3 Stab wound of LEFT lung causing pneumothorax usually
causing collapse of
a right lung
b left lung
c both

anyone who know the answer to these questions help me out
thank you

🙁 😕

 

[swavas]

hi the answers according to old question papers are:
1) attached gingiva

2)ant to prochordal plate

3)left lung

hope this helps
all the best

well i checked internet it says pneumothorax complication due to deep wounds on left lung causing right lung compression and deviation towards right i am not sure if this is right ,but in the question there is a phrase usually so....only god knows and hope this is a curving question
A stab wound sustained to the chest area may cause tension pneumothorax, open pneumothorax, massive hemothorax, sucking chest wound, flail chest due to fractured ribs, and pericardial tamponade. The victim can also suffer from severe respiratory distress due to hypoxia, which results from:

Diminished blood volume due to bleeding.

Contusion of the lungs leading to ventilation failure.

Changes in the pressure relationship within the pleural space leading to displacement of mediastinal structures and collapse of the lungs.

Since hypoxia is the most important feature of chest injury, early intervention is designed to ensure that an adequate amount of oxygen is delivered to the portions of the lung capable of normal ventilation and perfusion. Tension pneumothorax develops when a one-way valve air leak occurs, either from the lung or through the chest wall. The presence of air in the thoracic cavity causes collapse of the lung, mediastinal shift to the opposite side causing interference with venous return, and compression of ventilation to the other lung

thanks for reply

Hey,
1- attached gingiva.
2- ant to prochordal plate .
3- left lung.
good luck

 

[mekha]

the answer attached gingiva is wrong , after extensive research i think i have the answer

answer is 1) finger tip has most receptors then comes lip then soft palate alveolar ridge and thenar region in the order

so i think answer should be palate .

Hi,
I tried searching and this is what i found out..

The experience a subject reports when he is touched lightly is called pressure or touch. The amount of pressure required to produce this experience varies greatly for different parts of the body. For example the tip of the tongue, the lips, fingers, and hands are more sensitive than arms and legs.

so..answer can be the tip of the tongue as well..am nt sure

Sense of Touch
==============
The least sensitive part of your body is the middle of your back.
The most sensitive areas of your body are your hands, lips, face,
neck, tongue, fingertips and feet.
There are about 100 touch receptors in each of your fingertips.

part1 july 1989 anatomy question 97s key is wrong
Question
which of the following arteries is not derived from the celiac trunk or its branches?
1) left gastric
2) short "
3) gastroduedanal
4)left gastroepiploic
5)inf pancreaticoduedonal


answer given in key is 4 ie left gastroepiploic

left gastroepiploic is a branch of splenic artery which is a br of celiac trunk

but the real answer is 5
inf pancreaticoduedanal br of Superior mesenteric artery which is not a br of celiac .


The superior mesenteric artery arises from the anterior surface of the aorta just inferior to the origin of the celiac trunk, and supplies the intestine from the duodenum and pancreas to the left colic flexure.
Just after the superior mesenteric artery passes behind the neck of the pancreas it starts giving off its branches
* inferior pancreaticoduodenal
* middle colic - to the transverse colon
* right colic - to ascending colon
* ileocecal - to last part of ileum, cecum, and appendix
* intestinal branches - to jejunum and ileum

most prominent mechanism of spread of varicella zoster in suceptible population is by which routes
1direct skin to skin contact
2respiratory
3parentrally

peptic ulcer's complication accounting for majority of deaths
1) bleeding
2) perforation
3)obstruction

well checking web sites VZ route seems direct skin to skin and respiratory

for peptic ulcer too says bleeding perforration and obst

closest what i assume is
1direct skin to skin for VZ
and bleeding for peptic ulcer

is this right answers ? help me out 😕
thank you

1)warning sign of impending artheroscelrotic brain infarct
1berry aneurysm rupture
2transient ischemic attack
3angina pectoris

2)60 yr man had atrial fibrillation for two years
following myocardial infarct ,later he experienced right
flank and hematuria,paralysisof right side
of body and sharply demarcated ischemia in left foot
these signs and symptoms are most likely due to
1arterial emboli
2venous thrombi
3venous emboli

3 characteristic feature of negative stranded virus

a virion RNA complimentary to viral messenger rna
b genome is segmented always
c virion RNAis messenger for protient synthesis
d virion protient synthesised in eqimolar quantity
if anyone know the answer with explanation to these questions

help me out
thank you

the answer attached gingiva is wrong , after extensive research i think i have the answer

answer is 1) finger tip has most receptors then comes lip then soft palate alveolar ridge and thenar region in the order

so i think answer should be palate .

the answer according to one of the asda released papers is attached gingiva.

hi
i think the ans' should be
1) 1

2) 1

3) a- given in the decks that the viral rna with -ve polarity has a base sequence that is complimentary to the mRNA i.e. if mRNA has C-U-G-A then the the viral rna with +ve polarity will have the same sequence and -ve polarity will have the complimentay G-A-C-U
