What type of muscle cell is highlighted?

Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sacromere, produces these striations. In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.

What muscle structure is continuous with the Perimysium?

It is also continuous with tendons, where it becomes thicker and collagenous. In anatomy, a muscle fascicle is a bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue.

What are the 4 properties of muscles?

All muscle tissues have 4 characteristics in common:
  • excitability.
  • contractility.
  • extensibility - they can be stretched.
  • elasticity - they return to normal length after stretching.

What are three different types of muscles?

The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.

What does striation mean?

Medical Definition of striation 1 : the fact or state of being striated. 2 : a minute groove, scratch, or channel especially when one of a parallel series. 3 : any of the alternate dark and light cross bands of a myofibril of striated muscle.

What are the 7 steps of muscle contraction?

Terms in this set (7)
  • Action potential generated, which stimulates muscle. ...
  • Ca2+ released. ...
  • Ca2+ binds to troponin, shifting the actin filaments, which exposes binding sites. ...
  • Myosin cross bridges attach & detach, pulling actin filaments toward center (requires ATP) ...
  • Muscle contracts.
  • What are the steps of a muscle contraction?

    The process of muscular contraction occurs over a number of key steps, including:
    • Depolarisation and calcium ion release.
    • Actin and myosin cross-bridge formation.
    • Sliding mechanism of actin and myosin filaments.
    • Sarcomere shortening (muscle contraction)

    What is the process of muscle contraction?

    Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.

    Which structure is highlighted in the heart?

    Which structure is highlighted dense regular connective tissue?

    Dense Regular Connective Tissue In this type of tissue, the collagen fibres are densely packed, and arranged in parallel. This type of tissue is found in ligaments (which link bone to bone at joints) and tendons (connections between bones or cartilage and muscle).

    What is the Hypodermis?

    The hypodermis is the innermost (or deepest) and thickest layer of skin. It is also known as the subcutaneous layer or subcutaneous tissue. The layers of the skin include the epidermis (the outermost layer), the dermis (the next layer which is loaded with blood vessels and nerves), and then the hypodermis.
