2. Skeletal Muscle - Attached to bone via tendons -Voluntary/conscious - Stimulated by motor neuron to contract - A muscle (eg. biceps) are made of several long cells called muscle fibres. - Each muscle fibre has many nuclei as it is made from several cells fused together. (nuclei found just beneath plasma membrane with mitochondria) - Striated (due to myosin and actin filaments)

3. Cardiac Muscle - Involuntary (not under conscious control - Striated (myosin, actin filaments – sliding filament theory) - Fibres are short and thin that branch & interconnect with each other - Fibres consist of individual cells connected by intercalated disks & gap junctions to allow the flow of electrical impulses between cells - Each muscle cell is called a myocyte - 1 Nucleus per cell (found centrally) - Lots of mitochondria

5. Your task Compare skeletal muscle with cardiac muscle as two tissues. –Explain how both tissues have a similar function and how they each carry out that function –Describe the differences between the tissue structure –Include details on the cells components (eg. nucleus, mitochondria) and their role in the tissue function. –Illustrations of the tissues and their structure would be useful in this comparison. REMEMBER…Compare means discuss both the SIMILARITIES and DIFFERENCES!
