    • 6.1: Introduction to Muscle Tissue
      This page discusses the three muscle tissue types: skeletal (voluntary, attached to the skeleton), smooth (lines hollow organs), and cardiac (involuntary, forms heart walls). It highlights learning objectives for identifying muscle structures at both microscopic and gross levels, detailing the functions of myofibrils, myofilaments, and intercalated discs in cardiac muscle.
    • 6.2: Structures of Muscle Tissue
      This page covers the three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscle is large, striated, and responsible for voluntary movements, while cardiac muscle is striated and involuntary, pumping blood. Smooth muscle is spindle-shaped, non-striated, and also involuntary, supporting movement in hollow organs. Each type has unique structural and functional features.
    • 6.3: Microscope Slides - Muscle Tissue
      This page provides instructions for observing and labeling skeletal, cardiac, and smooth muscle tissues using a microscope. Students learn to identify specific structures, including muscle fibers and nuclei, while adhering to microscopy techniques. The exercise aims to deepen understanding of muscle tissue organization, with each labeled structure contributing to a total score.
    • 6.4: Questions and Review - Muscle Tissue
      This page covers muscle tissue, detailing definitions and identification exercises for various muscle types, such as skeletal, cardiac, and smooth muscles. It explains the sarcomere as the contractile unit of skeletal muscle and introduces muscle cells (myocytes), along with the roles of the sarcoplasmic reticulum and sarcolemma. Labeling tasks for sarcomere structures enhance understanding of muscle tissue identification.
