Most fascia of the body that attach to bones attach by which of the following mechanisms?
Blending with the covering periosteum
Inserting deeply into the cancellous bone
Inserting deeply into the cartilage
Inserting deeply into the diaphysis

Most fascia of the body that attach to bones attach by which of the following mechanisms?
Blending with the covering periosteum..............answer
Inserting deeply into the cancellous bone
Inserting deeply into the cartilage
Inserting deeply into the diaphysis

With this in mind, let us look more closely at what fascia is. Fascia is the fibrous material that gives the ultimate structure of our bodies. Every muscle is surrounded by fascia, and the outer layer of the bones, called the periosteum, is also fascia. In fact, the fibers that surround the muscle are continuous through the tendon to the periosteum, as illustrated below.
The fibers of the fascia are continuous from around the muscle through the outer layer of bone

[Autoclave12]

Can u explain why not it is apoptosis
3. A tissue which is not responded to cell replication & growth
a. necrosis
b. apoptosis----ANSWER

..

 

[bratdoc]

Can u explain why not it is apoptosis
3. A tissue which is not responded to cell replication & growth
a. necrosis
b. apoptosis----ANSWER

Because necrosis is premature cell death due to causes external to the cell....

Apoptosis is programmed cell death by the internal structures of cell itself..
so since the question asks if a cell does not respond to cell replication and growth... might be of no use to the tissue anymore or may have completed its growth and fulfilled its function-- it is internally lysed by the process of apoptosis

 

[Autoclave12]

bratdoc,
I think the answer is vertebral fracture because pt with hysterectomy has estrogen deficiency which may lead to osteoporosis i.e., vertebral fracture. what do u think??
5. Pt with hysterectomy is more prone to
a. vertebral fracture
b. renal failure----ANSWER...Uterus removal causes Urinary incontinence
c. lung cancer

..

 

[anniemirza]

@bratdoc
5. Pt with hysterectomy is more prone to
a. vertebral fracture-MY ANSR
b. renal failure----ANSWER...Uterus removal causes Urinary incontinence??????????
c. lung cancer
Hysterectomy causes weakening of the bones leading to fractures and osteoporosis which is usually seen in lumbar and thoracic vertebra.


@autoclave...
proteins are present in serum which increases in edema due outflow of liquid in the interstitial spaces causing "increase in protein concentration inside " and not decrease as given in the options.

 

[bratdoc]

bratdoc,

5. Pt with hysterectomy is more prone to
a. vertebral fracture
b. renal failure----ANSWER...Uterus removal causes Urinary incontinence
c. lung cancer

Estrogen is produced mainly in the ovaries by the developing follicles and the corpus luteum!! and ovaries are not removed in hysterectomy!!!

You are confusing this with postmenopausal estrogen deficiency...

btw what is the original answer in the answer key?

 

[pb2007]

pb2007,
can u explain the answers u marked

apoptosis is programmed cell death so there are irreversible cell damage like pyknosis ,karryolysis..... so there is no chance of its regeneration .

sorry starvation ques was answered wrong by me.

 

[bratdoc]

Autoclave12 be sure to post the correct answers here also...... not too sure about renal failure or fracture

 

[anniemirza]

@BRATDOC
urinary incontinence like u said above is ofcourse there but nowhere it is stated that it causes kidney failure in hysterectomies.urinary incontinence can be treated wid medicines and generally fades away....not leading to kidney failure...

[bratdoc]

1. Pt jaw is deviating to right. which is effected?
a. Rt lateral pterygoid on rotation---ANSWER
b. Rt lateral pterygoid on translation
c. Lft lateral pterygoid on rotation----my answer
d. Lft lateral pterygoid on translation
The lateral pterygoid muscle is responsible for moving the lower jaw from side to side when the right or left lateral pterygoid is active separately. Contraction of the right lateral pterygoid muscle moves the jaw to the left, and contraction of the left draws the jaw to the right. It is also responsible, in combination with the digastric muscle for opening the lower jaw during the translation phase of opening. It is shaped a bit like a partly unfolded fan.
waiting for the answer key...

Just remember both the lateral pterygoids move simultaneously to depress the jaw and protrude it... so if the lateral pterygoid muscle on oneside is not working the jaw will not be able complete its movement on the same side hence the deviation seen on the same side, as on the other side the muscle is functioning normally to carry out the normal depression and protrusion..... same is for condyle fracture also... jaw deviates towards the side of lesion..... jaw deviation is a very common question on the ASDAs and other question papers.. kindly check

u answered the sex hormones are not produced by adipose tissue. breast which is an adipose tissue produces sex hormones right. does adrenal medulla produces any sex hormones? it only produces catecholamines.Plz shed some light on this

[elmos]

i think it's vertebral fracture,
When only the uterus is removed there is a three times greater risk of cardiovascular disease. If the ovaries are removed the risk is seven times greater. Several studies have found that osteoporosis (decrease in bone density) and increased risk of bone fractures are associated with hysterectomies.[31][32][33][34][35][36] This has been attributed to the modulatory effect of estrogen on calcium metabolism and the drop in serum estrogen levels after menopause can cause excessive loss of calcium leading to bone wasting.

for antibodies structure kaplan mentions sturctural differences in constant region of heavy chain account for their biological behaviour.
for goblet cell luk at this link

i think air spaces never increase in asthma its a feature of emphysema .
lets see what others have to say on this .

for mitral valve have a look at this link .

need to confirm this fact
came across a ques frm packet E anatomy ,ques no 31 which is related to how bifid uvula results n answer given is faliure of complete fusion of palatine shelves which makes sense but was lookin in wikipedia which say its coz of incomplete fusion of medial nasal and maxillary process.

i think the answer is E as well. i think you can have hyperplasia of goblet cells (which leads to the blockage of mucous). hope this helps.

mandibular canine for sure
remember this fact ...mandibular canine is the anterior tooth most likely to have a bifurcated root .

mandibular canine for sure
remember this fact ...mandibular canine is the anterior tooth most likely to have a bifurcated root .

i've heard that before... but i've seen soooooo many mandibular incisors that have bifurcated roots so i was very unsure 🙁

the mesiolingual cusp resides in central fossa n distolingual of maxillary resides between marginal ridges of 1st and 2nd molar so so may be it should be lingual surface of maxillary distofacial cusp.will wait to hear from others

have another doubt .
ques no 52 frm anatomy series F mentions that portion of hard palate located directly posterior to maxillary central incisors is derieved from the
median nasal process but i read that palate is fromed by fusion of primitive palate {frontonasal process } with palatal process of maxillary bone .

i'm confused if between frontonasal n palatal part of maxillary bone medial nasal too comes.pz clarify if anybody has idea abt this .
