This book describes Smooth Muscles, Functions, Diseases, Diagnosis and Treatment and Related Diseases
Learning muscle contraction can be quite a beast
Complex and detailed, to say the least
But with this poem, you are sure to learn
How the muscles work, why at times they burn

Intimidating, I know, but it is not to worry
Just keep on reading and you'll learn in a hurry
All is launched by an Action Potential
Traveling in a neuron to a voltage gated channel

This tells the Calcium to move on in
And trigger the ACH that it's ready to begin
ACH crosses the cleft to enter the cell
And calls up the Sodium to come in as well

This changes the charge inside the fiber
The charge is a key and the muscle the driver
If threshold is reached, Action Potential is sent
It moves down the membrane, straight and not bent

T-tubules are next in the APs passage
And our hero calcium is back to send quite a message
Calcium is a bouncer bumping troponin from the club
Typtomysoin is troponin's friend, also dubbed a scrub

They are taken off actin so myosin can bind
And begin the cross bridge cycling all in a line
This is what causes the muscle contraction
The heads moving quickly in concerted action

But this cycle cannot continue forever
The muscle must relax or enter rigor
So to keep you from becoming a stiff
ATP comes along like a Christmas gift

The perfect amount to release myosin heads
And let them return home to rest in their beds
Now what I just detailed is only one type of muscle
We have 3 different kinds all helping us hustle

Skeletal, smooth, and cardiac are the 3. Each make us move
They keep our hearts beating and let our legs groove
Cardiac and smooth function differently then described
They have unique physiologies by which they abide

Smooth muscles does not use troponin to go
Cardiac muscles do, but their rate of potential is slow
This happens because their calcium channels are left open
To keep the heart contracting and the muscles not frozen

Smooth and Cardiac muscle cells both have gap junctions
To call each other on the phone and invite friends to functions
One says, "hey lets move. There's a burrito coming down."
And the others join in immediately to churn the lunch around

There are many more details and information to describe
But this poem is enough to understand how muscles work inside

By Anna Taylor
Smooth 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 body
Life and death of a smooth muscle
My 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 uterus
One 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 muscle
We smooth muscle cells may be organized in...
