3 types of muscle tissue
Smooth muscle tissue- Found associated with numerous other organs and tissue systems such as the digestive system or respiratory system. It plays an important role in the regulation of flow in such tissues in aiding the movement of food through the digestive system.
Non-striated, although it contains the same myofilaments they are just organized differently, and involuntary. Smooth muscle myocytes are spindle shaped with a single centrally located nucleus.
Cardiac Muscle Tissue- found only in the heart where cardiac contractions pump blood throughout the body and maintain blood pressure.
Striated but not consciously controlled and is involuntary. It can be further differentiated from skeletal muscle by the intercalated discs which control the contraction of cardiac tissues. Cardiac myocytes are shorter than skeletal equivalents and contain only one or two centrally located nuclei.
Skeletal muscle tissue-Skeletal muscle mainly attaches to the skeletal system through tendons to maintain posture and control movement.
Some skeletal muscle can attach directly to other muscles or the skin.
Is under voluntary control, but can be subconscious when maintaining posture or balance. Skeletal myocytes are elongated and tubular and appear striated with multiple peripheral nuclei.
