Smooth Muscles, Functions, Diseases, A Simple Guide To The Condition, Diagnosis, Treatment And Related Conditions

This book describes Smooth Muscles, Functions, Diseases, Diagnosis and Treatment and Related DiseasesLearning muscle contraction can be quite a beastComplex and detailed, to say the leastBut with this poem, you are sure to learnHow the muscles work, why at times they burnIntimidating, I know, but it is not to worryJust keep on reading and you'll learn in a hurryAll is launched by an Action PotentialTraveling in a neuron to a voltage gated channelThis tells the Calcium to move on inAnd trigger the ACH that it's ready to beginACH crosses the cleft to enter the cellAnd calls up the Sodium to come in as wellThis changes the charge inside the fiberThe charge is a key and the muscle the driverIf threshold is reached, Action Potential is sentIt moves down the membrane, straight and not bentT-tubules are next in the APs passageAnd our hero calcium is back to send quite a messageCalcium is a bouncer bumping troponin from the clubTyptomysoin is troponin's friend, also dubbed a scrubThey are taken off actin so myosin can bindAnd begin the cross bridge cycling all in a lineThis is what causes the muscle contractionThe heads moving quickly in concerted actionBut this cycle cannot continue foreverThe muscle must relax or enter rigorSo to keep you from becoming a stiffATP comes along like a Christmas giftThe perfect amount to release myosin headsAnd let them return home to rest in their bedsNow what I just detailed is only one type of muscleWe have 3 different kinds all helping us hustleSkeletal, smooth, and cardiac are the 3.
Each make us moveThey keep our hearts beating and let our legs grooveCardiac and smooth function differently then describedThey have unique physiologies by which they abideSmooth muscles does not use troponin to goCardiac muscles do, but their rate of potential is slowThis happens because their calcium channels are left openTo keep the heart contracting and the muscles not frozenSmooth and Cardiac muscle cells both have gap junctionsTo call each other on the phone and invite friends to functionsOne says, "hey lets move.
There's a burrito coming down."And the others join in immediately to churn the lunch aroundThere are many more details and information to describeBut this poem is enough to understand how muscles work insideBy Anna TaylorSmooth muscle is non-striated, uni-nucleate, and under involuntary control regulated by the autonomic nervous system. Smooth muscles are muscle tissue present in the walls of hollow organs, e.g.
blood vessels, the digestive tract, the uterus, etc. Smooth muscles, which can not be voluntarily regulated, normally happen in sheets or layers, one layer of muscle behind another. These muscles function all over the bodyLife and death of a smooth muscleMy name is Smooth Man the smooth muscle cell. I was named Smooth Man by my friends who feel that I am a very smooth character. My body is smooth and spindle shape.
My body can glide within the walls of the gut, blood vessel, urinary tract and uterusOne way to distinguish us smooth muscle from striated muscle is the absence of the regular pattern of sarcomeres (no A, I bands or Z lines). We Smooth muscle cells can be distinguished from connective tissue by our organized appearance. We smooth muscles are divided into two sub-groups:The single-unit (unitary)The multiunit smooth muscleWe smooth muscle cells may be organized in 2-3 layers.
One layer may run circularly around the lumen;Another layer may be running longitudinally along the length of the organ. In the stomach, there is a layer that runs more diagonallyMy death is by apostosis or necrosisTABLE O...
