a. genial tubercle
b.left condyolar neck
c.right condylar neck
d.left mental foramen

I think it's the Biceps brachii and pectoralis major.

It's pectoralis minor. The coracoid process is the site of origin for Coracobrachialis M and the short head of Biceps Brachii M and site of insertion for Pectoralis minor M.
Pectoralis major inserts on the Humerus.

sorry was bit confused the ans for q 130 i s b

and abt the sangers method http://www.bio.davidson.edu/Courses/Molbio/MolStudents/spring2003/Obenr ader/sanger_method_page.htm

thanks for the info.i just checked it out... however i think it sums up to "transcription" because it says"These modified nucleotides, when integrated into a sequence, prevent the addition of further nucleotides"
won't nucleotides be integrated in transcription??
what do you say???
and could you explain Q130
i somehow feel ans shd. be "b" but am not sure.
let me know

hi what is sustentacular cells?..

...since in anat decks its location is internal ear, taste buds....and in physio decks it is sertoli cells...i am confused 😕

-thanks

 

[wise146]

A sustentacular cell is a biological cell that is part of an epithelium and that supports other cells. Examples of sustentacular cells are Sertoli cells, which support germ cells in the seminiferous tubules, or the cells of the olfactory epithelium, which help in olfaction

E. Fibrinogen


Which of the following sweetners is non-nutritive as well
as non-cariogenic?
A. D-fructose
B. Saccharin
C. Galactose
D. Sorbitol

I was wondering why the answers to the above were
not (C) and (D) respectively.

A. D-fructose
B. Saccharin
C. Galactose
D. Sorbitol

...

Saccharin (calorie-free sweetener) has no nutritional value and is excreted unchanged by the body

 

[dat_student]

...
I was wondering why the answers to the above were
not (C) and (D) respectively.
...

I apologize. I didn't see that part of the question the 1st time I read it:

Galactose is also called "brain sugar." It is found in dairy products

Sorbitol is an artificial sweetener often used in diet foods (including diet drinks). It is called a "nutritive sweetener" because it provides 2.6 calories

P.S.
Many studies have shown a correlation between saccharin consumption and increased cancer (especially bladder cancer) and others have shown no such correlation.
According to saccharin.org, "Concerns over saccharin's safety were first raised twenty years ago after a flawed study that administered huge quantities of the sweetener to laboratory rats produced bladder tumors in rats. New and better scientific research has decisively shown that the earlier rat studies are not at all applicable to humans."

I have my exam in a couple of days & i need help with some ques.Pls. gve any input you can

explain it to me in a few words.

2.Mass movement occur in the large intenstine when
food enters which of the following?

d. Hypertension.
e. Hyperkalemia.

I think answer is E

since cortisol has anabolic effect on protein and aldosterone causes increased excretion of K in renal tubules. so der ll be no hyperkalamia

correct me if i am wrong

Cushing's Syndrome causes the following:

1) mobilization of fat
2) excess secretion of steroids
3) Hypertension
4) increased blood glucose concentration
5) protein catabolism
6) osteoporosis (loss of minerals)

The exception is "a. Increased protein anabolism.
" So, "A" is the correct answer.

 

[dat_student]

plasma colloidal pressure is equal to?


rocknsun

In blood plasma, the dissolved compounds have an osmotic pressure. A small portion of the total osmotic pressure is due to the presence of large protein molecules; this is known as the colloidal osmotic pressure, or oncotic pressure. Because large plasma proteins can't easily cross through the capillary walls, their effect on the osmotic pressure of the capillary interiors will, to some extent, balance out the tendency for fluid to leak out of the capillaries

Can anyone help me.........
Q Which of the the following do striated M, skeletal M and cardia M have in common?
A. Hyperplasia of these elements is common
B. They have a limited capacity to regenerate
C. Hypertrophy is a common response to injury.
D. They need a constant high O2 concentration to function.

One of the Q papers has B as answer and other has D. I am confused as both of them are right.

i think its not D bcoz skeletal muscles produce lactic acid under low oxygen tension,though cannot be carried for long,but still

so its B

plz correct me if i am wrong

 

[Anushri]

i think answer is B too.

After an automobile accident , a patient's chin deviates to the left on opening mouth widely.His mandible is probably fractured at which of the following points?

a. genial tubercle
b.left condyolar neck
c.right condylar neck
d.left mental foramen
e.right mental foramen

post the correct anwer and justify it with right explanation

hi,the answer is ,right condylar neck. forces applied by the muscles, keep the mandible in position.when,a fracture occurs ,muscles cannot exert their forces on the fractured side,where as in the unaffected side,that is the right side,the muscles r in contact with the condyle and they pull the condyle ,causing the mandible to deviate to the unaffected side.

regards,
nikhitha
