Skeletal Muscle/Voluntary Muscle
![card image](http://stevegallik.org/sites/histologyolm.stevegallik.org/images/SkeletalMuscle_2.jpg)
-attaches to the skeleton
-shapes the body and gives you the ability to move
-most of the muscle tissue in the body
-consciously controlled
-striated
Fibers
![card image](http://media.tumblr.com/b1880c52e4464f99c7c39e4161adffaf/tumblr_inline_mhq3dd3ctL1qz4rgp.jpg)
-large, long cylindrical cells that makes up skeletal muscle
-multinucleated
Sarcolemma
![card image](http://people.eku.edu/ritchisong/musclecell.jpg)
-membrane enclosing a striated muscle fiber
Myofibrils
![card image](http://people.eku.edu/ritchisong/musclecell.jpg)
-a contractile fibril of skeletal muscle
-made up of myofilaments
Myofilaments
![card image](http://classconnection.s3.amazonaws.com/959/flashcards/1239959/jpg/myofilament1350278068423.jpg)
-composed of actin and myosin, which slide past each other during muscle activity to bring about shortening and contracting of the muscle cells
Sarcomere
![card image](http://www.pradeepluther.com/pklwork19may02/images/Sarcomere_diagram.jpg)
-contractile units of muscle
-extends from the middle of one I band (its Z disc) to the middle of the next along the length of the myofibrils
Transverse Tubule (t tubule)
![card image](http://s3.amazonaws.com/rapgenius/1379383737_54i1hk.png)
-deep invagination of the sarcolemma
Terminal Cisterns
![card image](http://classconnection.s3.amazonaws.com/947/flashcards/1037947/png/terminal_cisterna1323998195057.png)
-pairs of tranversely oriented channels that are confluent with the sarcotubules, which together with an intermediate T tubule constitute a triad of skeletal muscle
Triads
![card image](http://upload.wikimedia.org/wikipedia/commons/thumb/9/94/1023_T-tubule.jpg/400px-1023_T-tubule.jpg)
-regions where the sarcoplasmic reticulum terminal borders a t tubule on each side.
Endomysium
![card image](http://upload.wikimedia.org/wikipedia/commons/8/89/Illu_muscle_structure.jpg)
-delicate areolar connective tissue that encloses each muscle fiber
Perimysium
![card image](http://upload.wikimedia.org/wikipedia/commons/8/89/Illu_muscle_structure.jpg)
-collagenic membrane surrounding several muscle fibers
Fascicle
![card image](http://upload.wikimedia.org/wikipedia/commons/8/89/Illu_muscle_structure.jpg)
-bundle of fibers
Epimysium
![card image](http://upload.wikimedia.org/wikipedia/commons/8/89/Illu_muscle_structure.jpg)
- large number of fascicles bounded together by dense connective tissue
Deep Fascia
-coarser sheets of dense connective tissue that bind muscles into functional groups
Insertion
![card image](http://legacy.owensboro.kctcs.edu/gcaplan/anat/images/Image283.gif)
-a muscles more movable attachment
Origin
![card image](http://legacy.owensboro.kctcs.edu/gcaplan/anat/images/Image283.gif)
- a muscles immovable attachment
Neuromuscular/Myoneural Junction
![card image](http://www.unm.edu/~lkravitz/MEDIA2/Neuro2.gif)
- junction between an axon of a motor neuron and a muscle cell
Motor Unit
![card image](http://upload.wikimedia.org/wikipedia/en/8/8b/Anatomical_diagram_of_the_motor_unit.jpg)
-a neuron and all the muscle fibers it stimulates
Synaptic Cleft

-small fluid-filled gap separating the neuron and muscle fiber membranes
