# Types of Muscle Fibres - **Red Muscle Fibres:** - More myoglobin (O2 store) giving reddish appearance - More blood capillaries - Mitochondria more - Aerobic respiration - Less 'SR' - Slow contraction - Example: Human back muscle - **White Muscle Fibre:** - Less myoglobin (whitish appearance) - Less blood capillaries - Mitochondria less - Anaerobic respiration - Lactic acid accumulation - More SR - Fast contraction, easily fatigue - Example: Eye muscle # Human Skeletal System - Skeletal connective tissue - Mainly bones - Matrix: Solid, hard & pliable - Calcium
