This guide explores the three main types of muscle tissue in the human body, their functions, and properties.
Location: Found in the digestive, reproductive, circulatory, and urinary systems.
Function: Operates involuntarily, controlling various internal processes.
Location: Exclusive to the heart.
Function: Regulated by the sinoatrial node to maintain a heart rhythm, typically around 72 beats per minute in a resting, healthy person.
Characteristic: Exhibits autorhythmicity, a specific heart contraction pattern.
Function: Facilitates movement by attaching muscles to joints via tendons, controlled voluntarily by the somatic nervous system.
Roles: Includes locomotion, posture maintenance, and internal substance transportation like glycogen.
Muscles generally possess four key properties:
