Muscle Part 2 – Muscle Groups Julie Watson Muscle Groups There are three main muscle groups: Striated or Skeletal Non Striated or Smooth or Visceral Cardiac 2 Muscle Groups 3 Striated/Skeletal Muscle Contracts to move limbs Each skeletal muscle fibre Maintains posture is roughly cylindrical in shape Both ends of muscle Fibre arrangement articulate the skeleton depends on the function of Attached to the bones by the muscle tendons Each muscle fibre has a Has blood vessels and long cylindrical shape nerves associated with it measuring between 0.02 to Under voluntary control 0.08 mm in diameter They vary in length Skeletal Muscle 5 Skeletal Muscle 6 Non Striated/Smooth/Visceral Muscle Found where movement of Only relaxes for short soft tissues structures is periods of time required e.g. Contraction of smooth Walls of blood and muscle can be sustained lymphatic vessels for long periods if required Alimentary canal The cells are long and Cells are spindle shaped narrow and spindle shaped with one centrally place Under the autonomic nucleus nervous system They are 0.005mm to 0.01mm in diameter and Smooth Muscle 8 Smooth Muscle 9 Cardiac Muscle Only found in the wall of Each fibre is roughly the heart rectangular in shape Exhibits rhythmic Has an intrinsic pacemaker contractions system Under the autonomic Has intercalated discs nervous system Cardiac Muscle 11 Cardiac Muscle 12 Comparison of Muscle Types 13 Comparisons Microscopically 14 Further Reading https://www.verywellhealth.com/atp-6374347 https://www.youtube.com/watch?v=loXOdSmP1tA https://www.youtube.com/watch?v=Ktv-CaOt6UQ https://www.youtube.com/watch?v=I80Xx7pA9hQ 15  https:// www.bbc.co.uk/bitesize/guides/zxkr82p/revision/1 https://www.youtube.com/watch?v=MZJ6kTKDFmw Youtube.com/watch?v=yzmCUHcYqNE Muscle Tissues Chapter 9 by Dr Michael Sliman Thank You For Your Attention 17
