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 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 diagonally

My death is by apostosis or necrosis
