    en.wikipedia.org/wiki/Striated_muscle_tissue

    Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres.The presence of sarcomeres manifests as a series of bands visible along the muscle fibers, which is responsible for the striated appearance observed in microscopic images of this tissue.

  4. Sarcomere - Wikipedia

    en.wikipedia.org/wiki/Sarcomere

    A sarcomere is defined as the segment between two neighbouring Z-lines (or Z-discs). In electron micrographs of cross-striated muscle, the Z-line (from the German "zwischen" meaning between) appears in between the I-bands as a dark line that anchors the actin myofilaments. Surrounding the Z-line is the region of the I-band (for isotropic). I ...

  5. Striatum - Wikipedia

    en.wikipedia.org/wiki/Striatum

    The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.

  6. Skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Skeletal_muscle

    While the muscle fiber does not have smooth endoplasmic cisternae, it contains sarcoplasmic reticulum. The sarcoplasmic reticulum surrounds the myofibrils and holds a reserve of the calcium ions needed to cause a muscle contraction. Periodically, it has dilated end sacs known as terminal cisternae. These cross the muscle fiber from one side to ...

    Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle.It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart.
