Types and structure
This muscle is found in the heart
Cardiac
This runs the length of the muscle fiber, shortens muscle during contraction
Myofibrils
This organ sends the signal to the muscle
Brain
What is the phrase that explains the all or nothing part of muscle contraction
Motor unit recruitment
The immune system attacks ACH receptors on the muscle
Myasthenia Gravis
muscle that lines the organs
Smooth
Functional unit of muscle contraction
Sarcomere
This releases calcium into the muscle
Sarcoplasmic reticulum
The place where a nerve cell meets a muscle cell
Neuromuscular junction
This produces a toxin that prevents the muscle from relaxing
Tetanus
Bicep is what type of muscle
Skeletal
Cell membrane of the muscle fiber
Sarcolemma
These 2 work together to move the electric signal along
Sarcolemma and T Tubules
This is the chemical messenger that tells a muscle to contract
acetylcholine
This blocks ACH receptors and is a poison
Curare
Muscle has how many layers
3 Fascia, Fascicles and Tendon
Tiny tunnels that go deep into the muscle fiber
T Tubules
Myocin gabs this to further the process
Actin
If ACH is the "key" what is the "lock"
Receptor sites
This toxin is used to reduce fine lines and wrinkes
Botulism
This attaches muscle to bone
Tendon
Storage area for Calcium
Sarcoplasmic Reticulum
This shortens to cause a contraction
Sarcomere
This is released by the sarcoplasmic reticulum
Calcium
This disease results from the dysfunction of dystrophin resulting in massive muscle fiber death
Muscular Dystrophy
