muscles and movement


1.Explain the three types of muscle tissue- Cardiac/Skeletal/Smooth

Skeletal muscles: these muscles are voluntary so for example if you flex your bicep your ,radius, and ulnar will move as well.

Cardiac muscles: this muscle is involuntary so it will contract with out the brain telling is to contract for example the heart.

Smooth muscles: these muscles are involuntary for example this would be found in the digestive system and would help push the food through the gastrointestinal tract. 

2.Where would you find examples of all three types

You would find the skeletal muscle in the bicep by flexing the bicep the ulnar and radius with move as the muscle is contracting.

The cardiac muscle would be the heart because its involuntary by contracting without the brain telling it to contract.

The smooth muscle would be found in the digestive system to push food through.
