Members don't see this ad.

is it muscle spindles or golgi tendons???
also, which of the following is a nucleotide? uracil, adenosine, thymidylate
thanks guys!

 

[confused tooth]

golgi tendon
thymidylate acid

I am not sure why, but this is it .....

Hope this helps,

[aphistis]

golgi tendon
thymidylate acid

Uracil is the nucleotide, not thymidylate.

 

[dds_aspirant]

It should be muscle spindle.
The muscle spindle cell has four assignments, which are 1) control and maintain muscle tone; 2) activate the dynamic stretch reflex mechanism; 3) maintain muscle contraction against the constant force of gravity (the static stretch reflex mechanism); and 4) control fine motor movements. ‘Static’ is in equilibrium, steady, balanced, constant. ‘Dynamic’ and ‘myotatic’ mean the same thing – constantly changing.

The other answer is Uracil

[confused tooth]

Well, if its Uracil, why cant it be Adenosine.......both have apentose sugar and a phosphate group?
Also as I remember, its Golgi tendons which measure tension present in individual muscle fibre.

Guys, Please this confusion is killing me......
Can anybody explain this.....

Thanks in advance

i think u r confusing adenosine with adenine.adenine(A) is present as a nitrogenous base not adenosine.
also,a nucleotide is base+sugar+phosphate.so it should be thymidylate

 

[dds_aspirant]

neucleotides:
Adenine,Guanine,Thymine,Cytosine,Uracil (The ATCG U)

Adenine,Guanine,Thymine,Cytosine,Uracil....these are the nitrogenous base,not nucleotides.
A nucleotide is a chemical compound that consists of a heterocyclic base, a sugar, and one or more phosphate groups. In the most common nucleotides the base is a derivative of purine or pyrimidine, and the sugar is the pentose (five-carbon sugar) deoxyribose or ribose


hope this helps👍

 

[drmon]

is it muscle spindles or golgi tendons???

golgi tendon controls muscle tone through gamma motor system

 

[confused tooth]

Thank you so much for the clarification, yes I was confused(as always ! ) between adenine and adenosine 🙁
Huum, now the answers make sense to me......

Thanks again,

Which of the following vessels contains the highest viscosity blood in the body?
A. aorta
B. vena cava
C. casa recta
Thanks in advance

 

[drmon]

Which of the following vessels contains the highest viscosity blood in the body?
A. aorta
B. vena cava
C. casa recta
Thanks in advance

viscosity is inversely proportional to flow and since the blood flow to vasa recta is slow,viscosity is high.
also,the slow blood flow in vasa recta makes them a likely place of thrombosis in hypercoagulable states.
hope this helps👍

 

[tina1]

but y not uracil then.

 

[tina1]

can anyone please help on this

Glucose is reabsorbed by:
a. co transport with amino acids in the proximal tubule only
b. secondary active transport in the proximal tubule only.

i think this question was in one of the threads but cant locate.
thanx in advance

glucose is reabsorbed by sec.active transport in PCT

is it muscle spindles or golgi tendons???
also, which of the following is a nucleotide? uracil, adenosine, thymidylate
thanks guys!

BASES : adenine,guanine,thymine,cytosine,uracil
NUCLEOSIDES: ADENOSINE ,GUANOSINE,CYTIDINE,THYMIDINE,URIDINE
NUCLEOTIDES:ADENYLATE,GUANYLATE,CYTIDYLATE,THYMIDYLATE,URIDYLATE
so theres no doubt ...answer is thymidilate

 

[deepa k]

then finally wat is the answer for controlling muscle tone??????
is it muscle spindle..

 

[scsux]

thanks meebo...u kno the answer to the muscle tone question..

Thanks a lot drmon for the answer and explanation.

muscle spindle measures muscle length
and
golgi tendon organ measure muscle tension...

(as given in dental decks)

 

[Dr. Ace]

Its still unclear to me...muscle spindle or G. tendon? Muscle spindles have 2 types of fibers, 1) nuclear bag fibers, which measure length and tone of the muscle and 2) nuclear chain fibers, which measure just length. Now, when the muscle is stretched, info is sent to the brain which will send info back to the alfa neurons to stimulate the extrafusal fibers to contract. At this point, the gamma neurons see that the muscle is contracted, letting the muscle spindle know that the stretching of the muscle is not occuring. This, in turn, will cause the muscle to be in its normal state. So...If the muscle is stretched, wouldnt it also have more tonicity? Wouldn't the muscle spindle maintain the tone also? Yes, the tension can be MEASURED by the G. tendon but that doesnt necesarily mean that the tone is.... someone please help me out here. Am I wrong?

I'm writing my exam in 2 weeks and the very fact that soooo many people have no idea how to answer these questions is seriously worrying me. I don't even consider these questions that confusing. Some questions are outright impossible. I'm gonna fail! Someone help me!😱

what controls the musle tone?

muscle spindles

When the muscle is stretched, so is the muscle spindle. The muscle spindle records the change in length (and how fast) and sends signals to the spine which convey this information. This triggers the stretch reflex (also called the myotatic reflex) which attempts to resist the change in muscle length by causing the stretched muscle to contract. The more sudden the change in muscle length, the stronger the muscle contractions will be.Gamma motor neuron regulate sensitivity of spindle afferents to dynamic and static phases of strech.Input through cns via gamma motor neuron regulate musle tone.This basic function of the muscle spindle helps to maintain the muscle tone and to protect the body from injury

golgitendons


When muscles contract (possibly due to the stretch reflex), they produce tension at the point where the muscle is connected to the tendon, where the golgi tendon organ is located. The golgi tendon organ records the change in tension, and the rate of change of the tension, and sends signals to the spine to convey this information. When this tension exceeds a certain threshold, it triggers the lengthening reaction which inhibits the muscles from contracting and causes them to relax.

so,the correct answer is muscle spindles

Hi don't worry! just go for "muscle spindle". I'm pretty sure this is the right answer!!!
