What is the myocardium? The myocardium is the heart muscle, the working muscles of the heart. It is striated like skeletal muscle, but thinner and with a special structure: The surface of the cardiac muscle fibers is covered by a lattice fiber network, and the nuclei are longer than in skeletal muscle cells and are … Myocardium
The threshold potential describes a specific charge difference at the membrane of excitable cells. When the membrane potential attenuates to a certain value in the course of depolarization, an action potential is induced via the opening of voltage-dependent ion channels. The value to be reached in each case, which is necessary for the generation of … Threshold Potential: Function, Tasks, Role & Diseases
The elastic protein titin consists of approximately 30,000 amino acids, making it the largest known human protein. As a component of sarcomeres, the smallest contractile unit of skeletal and cardiac muscles, titin provides the elastic connection between Z-disks and myosin heads in the form of filaments. Titin filaments are passively preloaded and retract the myosin … Titin: Structure, Function & Diseases
Senescence describes the degenerative process that accompanies natural aging. It is not a synonym for aging itself, but merely encompasses its degenerative aspects. What is senescence? Senescence describes the degenerative process that accompanies natural aging. Every living thing ages. The aging process is accompanied by senescence of its cells: that is, they do not divide … Senescence: Function, Tasks, Role & Diseases
Foxglove is a poisonous plant that is protected by law. Already in the 18th century, it found medical use against heart failure. In traditional medicine, ingredients of foxglove are still a proven remedy for heart disease today. Occurrence and cultivation of foxglove Foxglove grows as a biennial, herbaceous plant and grows up to two meters … Foxglove: Applications, Treatments, Health Benefits
Skeletal muscle refers to all muscles that are responsible for voluntary movements. This includes not only muscles that are directly adjacent to the skeleton. For example, the arm, leg, and shoulder muscles also fall under the umbrella term. What is skeletal muscle? Muscles that enable active movement of the body are part of the skeletal … Skeletal Muscle: Structure, Function & Diseases
Enchondral ossification is the indirect ossification from within, which occurs through the intermediate stage of cartilage. Connective tissue and mesenchyme are the basic materials for ossification. If the connective tissue is altered in structure, then it can cause severe ossification disorders. What is enchondral ossification? Enchondral ossification is the indirect ossification from within, which occurs … Enchondral Ossification: Function, Role & Diseases
Skin muscles are striated muscles between fascia and skin, which are rather underdeveloped in humans. The main function of the muscle form is skin movement, in humans mainly facial expression. Like all other muscles of the body, skin muscles can be affected by paralysis, such as peripheral facial nerve palsy. What is a skin muscle? … Skin Muscle: Structure, Function & Diseases
The mesenchyme envelops the fetus as embryonic connective tissue with a protective envelope and is relevant for morphogenesis. Multipotent mesenchymal cells differentiate into connective tissue, muscle, blood, and fat cells, among others, during embryogenesis. Because of its high division rate, mesenchyme is susceptible to tumors. What is the mesenchyme? During the embryonic period, the supporting … Mesenchyme: Structure, Function & Diseases
Soft tissues include all soft tissues except epithelia, internal organs, and glial tissue. Thus, adipose tissue, muscle tissue, and connective tissue are included in soft tissues. What is soft tissue? Soft tissue refers to a collection of differentiated cells including their extracellular matrix. Soft tissues are usually composed of collagen, elastin, and a ground substance. … Soft Tissue: Structure, Function & Diseases
