Skeletal Muscle

Skeletal muscle is one of the three types of muscle in the body. The tissue attaches itself to bone and represents a large portion of body weight on a human body.

The contraction of these muscles is responsible for movement in the body.

Muscle tissue

Muscle tissue is a contractile body tissue as well as the force behind all bodily movement. It's specialized to contract or shorten forcefully and is classified under three types: skeletal, cardiac, and smooth. The classification is according to the anatomic location and function of the muscle.

When classified by appearance, muscle can be striated (with thin parallel streaks) or nonstriated (without thin parallel streaks). When classified by function, it is voluntary (consciously controlled) or involuntary (not normally consciously controlled).

Let's go over the three types again, but further in depth:
Voluntary striated (skeletal)
Involuntary striated (cardiac)
Involuntary nonstriated (smooth)

Person 1: *existing*
Person 2: "Did you know that muscle tissue makes up a large portion of your body weight?"
Person 1: "Literally NOONE asked"

Valentines Beer Muscle

A special kind of muscle that can only be created by a few men in this world. To grow the type muscle you must drink many many bud lights whether it be keg can or bottle beer, as long as it's bud light. The only twist is that you have to be born on valentines day. In this case all the bud light that's consumed will become Beer Muscle because of all the 12 ounce curls and the females love it.

"Check out that guys muscles. I heard he doesn't even work out."
"He doesn't, he just drinks Bud Light every day and developed beautiful Valentines Beer Muscle"
