All About Muscles DVD

Understand muscle structure, functions and actions for AS and A2

This action animated DVD, suitable for AS/A2 students provides a detailed examination of the structure, function and action of muscles.

The DVD set including teacher's guide and photocopiable diagrams deals with the following topics and shows you:

• Muscle functions - voluntary and involuntary muscles; muscles having many different functions (e.g. facilitating movement, maintaining posture and regulating body heat)
• Types of muscle and muscle physiology (Part 1) - characteristics and functions of smooth, cardiac and skeletal muscles; structure and action of skeletal muscle (explains origin, moving end/ insertion, epimysium, tendons, fibres, fasciculi, perimysium, sarcolemma/sarcoplasm)
• Types of muscle and muscle physiology (Part 2) - explains structure and action of muscle fibre, looking at myofibrils, sarcomeres, actin and myosin filaments; three types of skeletal muscle - fusiform, pennate and radiate muscles; three types of joint (immovable fibrous, slightly movable cartilaginous, and synovial joints); bones connected by cartilage and protected by ligaments
• Muscle fibres - characteristics and functions of slow twitch and fast twitch muscle fibres
• Muscular contractions - muscles working in pairs (agonist and antagonist); three types of muscle contraction - isotonic (concentric/eccentric), isometric and isokinetic
• Inside the muscles - nervous control responsible for muscle contractions; role of sensory and motor neurons; outline of biochemical process for releasing energy to contract muscle.
