1. Tendon : attaches muscle to bone

2. Fascia : encloses muscles and separates them into groups

3. Ligament : attaches bone to bone or bone to cartilage

4. Origin : the less movable of the two points of attachment. Attaches to the fixed part of the skeleton

5. Insertion : the point of attachment by a muscle

8. Muscle cells

9. Skeletal muscle: also called voluntary muscle because they are controlled at will. Also called striated because they have a striped microscopic appearance. When muscles contract the fibers become shorter and thicker

10. striated

11. Smooth Muscle: also called visceral, nonstriated or involuntary muscle. Many of the internal organs are made of smooth muscle including:

13. bladder

14. uterus

15. Smooth muscle vs skeletal muscle

16. Cardiac muscle is involuntary but does show very fine striations

17. cardiac striated smooth

18. Muscle Attachments: attachment to tendons (eg phalanges) results in movement and reduces bulk. Voluntary muscles usually attach to bone.

19. Muscles may also be attached to skin, mucous membranes or the fascia of other muscles.
