It is made of interconnecting cells, whose cell surface membranes are very tightly joined together.
2. Single central nucleus
3. striated like skeletal muscle
4.This close contact between the muscle cells allows waves of electrical excitation to pass easily between them, which is a very important feature of cardiac muscle.]]> 2018-10-27 18:05:33 UTC https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297673359 1169696947 https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297673557 2018-10-27 18:08:02 UTC https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297673557 FONCTION tracyhung7201 https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297698344 1.

2. Branching cells connect at intercalated disks which allow contractions to occur faster.]]> 2018-10-27 23:44:19 UTC https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297698344 tracyhung7201 https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297699075 2018-10-28 00:01:32 UTC https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297699075 tracyhung7201 https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297699410 -Found in digestive system or respiratory system

-Attached to bones and move our skeleton]]> 2018-10-28 23:35:30 UTC https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297825530 STRUCTURE tracyhung7201 https://padlet.com/tracyhung7201/iym87w8su2u6/wish/297825637 1. Striated muscle 
2. Voluntary
3. More than one nucleus
4. Long, thin and cylindrical
5. Refers to multiple bundles (fascicles) of cells joined together called muscle fibers. The fibers and muscles are surrounded by connective tissue layers called fasciae.
6. Composed of myofibrils. The myofibrils are composed of actin, myosin and titin 
7. Repeated in units called sarcomeres.
8. The sarcomere is responsible for the striated appearance of skeletal muscle, and forms the basic machinery necessary for muscle contraction.
9. new fibers are produced by stem cells
10. Striations -- cross stripes (bands) run perpendicular to the cells
11. Blood vessels and nerves run through the connective tissue supplying muscle cells with oxygen and nerve impulses that allow for muscle contraction.

Provide movements by muscle contraction
2. contraction of skeletal muscle produce heat which help to maintain the body temperature
3. add stability to joints that have poor reinforcement
4. voluntary movement(e.g. limb,toe  neck, leg)
