Smooth Vs Striated Muscle
It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more
There are 3 types of: Muscle, skeletal-compose of our muscle mass attach to the skeleton; smooth-located in the walls of hollow visceral organs except the heart; cardiac or striated. In practice, the term is sometimes used to refer exclusively to cardiac when distinguishing it from smooth muscle. Other dictionaries called striated muscle to skeletal muscle. Good question! ...Read more
Muscle fibers forming pacemaker are less striated than other muscle fibers. But does it help the pacemaker conduct impulse faster, how?
Not clear?: No muscle fibers make the pacemaker. Pacemaker is an artificial device implanted in one's heart. The leas of a pacemaker are not in the muscle but in one of the heart vessels. ...Read more
Mucocele left sphenoethmoidal recess causing mild smooth compression upon inferior and medial recti muscles?
This means: You have sinus process pressing on the muscles that control eye movement. ...Read more
Smooth muscle is an involuntary non-striated muscle. It is divided into two sub-groups; the single-unit (unitary) and multiunit smooth muscle.
Smooth muscle is found within the walls of blood vessels. Smooth muscle is also found in lymphatic vessels, the urinary bladder, uterus, male and female reproductive tracts, gastrointestinal tract, respiratory tract, arrector pili of skin, and other places. ...Read more

What is the name of the smooth muscular structure that courses obliquely and medially superficial to the psoas muscles?
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. ...Read more
Why nitrate drugs only use for vescle smooth muscle? And they do not use for other human's body smooth muscle such as geastrointestinal?

Why is there a need for immunohistochemistry: smooth muscle actin after I got the diagnosis: cellular spindle cell lesion favor nodular fascitis?
To help diagnosis: Pathologists often use immunohistochemistry to help in arriving at a diagnosis. For softn tissue tumors immunohistochemistry can help better characterize the type of tumor...For example if is smooth muscle derived or a neural tumor etc. In terms of nodular fasciitis, it can morphologically appear similar to some smooth muscle tumors and some other fibroblastic tumors so ihc may be used. ...Read more
1. What percentage of the time does cidp or gb present without significant associated muscle weakness. 2. How can cidp or gb effect smooth muscle.?
See below: Commonly gbs starts with numbness and tingling that is bilateral and starting at the toes (variants of the disease differ in symptoms). Weakness has to be present for it to be gbs. Cidp is less predictable: weakness may not be present for a couple years. In these diseases peripheral nerves are stripped of myelin (the coating that allows for nerve transmission). Smooth muscle is not affected. ...Read more
Hi, my mastodis process seems asymmetrical. One on the left is more prominent and not as smooth as a other one. It does not hurt and it has no lumps, just feel to touch like it has more bumps. Also my scm muscle is tight could all this be linked?
Normal variant: This is likely a normal variant. Your mastoid processes do not have to be symmetric. Likely not related to your SCM. ...Read more
No: Concerta is methylphenidate, exactly the same molecule as ritalin. Concerta is formulated to be released into your bloodstream slowly so it lasts for 6 to 8 hours with a steady blood level, whereas Ritalin is absorbed rapidly and your blood level rises to a peak in about two hours and then declines, and is active for a total of about 4 hours. Same medication - same effects. ...Read more
What is a smooth muscle ab blood test and a titer test for, and what does it mean if they're positive?
I have mctd (+ana, rnp). Recent test when I was unwell + anti ro, sm/rnp, anti smooth muscle, antichromatin-low titres of most. What does all this mean? Is my disease progressive? I am terrified.
Dietary modification: Consult a comlementary dietitian or md to modify this. Very little remedy in western medicine. ...Read more

Electrolytes?: First thing to do is to rule out electrolyte abnormalities and other readily treatable conditions. We typically see fasciculations of the tongue with ALS. Another condition that can produce diffuse muscle twitching is hyperthyroidism. After excluding toxic / metabolic problems see a neurologist for an EMG and check of spinal fluid. (ALS and related disorders) ...Read more
Achalasia a name for: A behavior, not the reality of what is happening. Except for heart, no muscle cells in body contract without 0.001 sec nerve impulses to each muscle cell releasing neurotransmitter to trigger activation & contraction. Meds do not address, much less solve the real problems which are brain+neuromuscular. Since this is too complex for disease medicine, Docs focus only on aspects of end-body behavior. ...Read more
