And now an unfinished song.

a prechorus, chorus and part of a bridge

" In between the bones with tendons at both ends is an overworked and underrated contractile tissue friend" 

" My muscles move and groove me, guard entrances and exits, produce the heat that keeps me warm." 

" My muscles support soft tissues, maintain my body's posture, help me run to shelter in the time of storm."

" Muscles I am grateful for you! Yeah yeah yeah, when you don't know what to sing you sing yeah yeah yeah."

​Muscle is considered to be contractile tissue because it works by getting shorter.

(like a ratchet strap that ratchets super fast.)

Muscles can only pull, they can't push.

If you are pushing something, it is because muscles are pulling and getting shorter.

​The three most important things about a muscle.

​Origin - attachment of a muscle to a stationary

(non-moving) bone.

Insertion - attachment of a muscle to a moving bone.

Action​ - motion carried out by a muscle.

Where the ratchet straps attach and what bone moves when the muscle gets shorter.

Flexion - Decrease the angle between bones

Extension - Increase the angle between bones

Rotation - Spinning on an axis (not all the way)

Abduction - Move away from the midline

Adduction - Move toward the midline​

Plantar Flexion - Pointing toe (like a calf raise)
