Question 1

how much ischemia or partial ischemia can muscles handle before permanent damage is done? i.e. skeletal muscle like lower leg

Accepted Answer

Varies : The overall blood flow is the key. Muscles develop pain when the bloodflow is inadequate. That is the signal that ischemia is developing.

Question 2

what is the name of the smooth muscular structure that courses obliquely and medially superficial to the psoas muscles?

Accepted Answer

Sartorius: The sartorius runs superficial to the psoas in the direction you are describing, so that is the most likely possibility.  There are other structures in that area as we.

Question 3

doctors,i feel my head is so small.can i grow muscles around it to get a nice structure..and face    muscles.tnx in advance.

Accepted Answer

No: Once skull bones have fused, there is no easy way to enlarge/change size of head, short of major surgery. I'm not aware of any exercises, aside from smiling, to grow muscles already present on head &amp; face, unlike those on limbs. Of course, you may want to ask a plastic surgeon in your area but I'm pretty sure you'd get same answer. If this still bothers you, go see your doc who can refer to Psych

Question 4

to control premature ejaculation, stop and start technique is recommended but isn't doing that affects penis muscles or any structure responsible for sperm/semen release? what happens to the semen which was about to release but forcefully stopped???

Accepted Answer

: The semen wait until it is time to be released. They really don't have much of a choice.

Question 5

runner. high arches. i find my hip flexor  and soleus muscles hypertrophied. can anyone relate foot structure to biomechanics?

Accepted Answer

See an orthopaedist: High arches themselves are common and do not necessarily correlate with problems.  Consult with an orthopaedic surgeon and consider an evaluation with a physical therapist to see with their are aspects of your running style that need modifications.

Question 6

i was wondering what are the differences between cardiac (heart) and skeletal muscle contractile tissue?

Accepted Answer

Cardiac vs Skeletal: It is difficult to describe in this limited space. Refer to the site:

Question 7

i had a fnac on enlarged axillary lymph node, neg. ca. biopsy showed , fibroadipose tissue, and rare skeletal muscle fragments? u/s in cpl. mo.

Accepted Answer

Unclear question: From what you described you did not have an enlarge node, but a fibro-fatty mass, and you do not have cancer in the armpit.

Question 8

skeletal muscle are voluntary or involuntary?

Accepted Answer

Voluntary: For the most part, if you have a body part composed of skeletal / striated muscle, you can move it. Not everyone can wiggle their ears or contract skeletal muscle that helps position the testis.

Question 9

why do i have extreme high levels of ck (skeletal muscle enzymes) be the result of?

Accepted Answer

CPK: Creatine (phospho)kinase. This enzyme will be elevated generally in disorders that injure muscle or when muscles are not working right.  Extremes of exercise or injury can cause this, as can disorders of the muscles themselves, some hereditary.  There are other forms of the enzyme that can come from other parts of the body, so this should be evaluated by a practitioner.

Question 10

what is it called when skeletal muscle fibers break down?

Accepted Answer

Apoptosis, due to: either ischemia or mechanical stress beyond what the phospholipid+cholesterol bilipid layer membranes of the muscle cell can endure without inducing cell death. When large quantities of muscle fibers die, commonly used terms include:  rhabdomyolysis, myocardial infarction, ischemic infarction of bowel, etc., etc.
