What are some characteristics of cardiac muscle fibers quizlet?
- Small cells with single nucleus.
- Intercalated discs- allows for gaps in between cells to deliver messages.
- Automaticity- has the ability to contract without neural stimulation.
- Pacemaker cells- set the pace for cardiac muscle cell contraction.

What are the 4 differences between cardiac and skeletal muscle?
Cardiac Muscles are found in the Heart and are involuntary muscles. Skeletal Muscles are attached to the bones and are voluntary in nature. Cardiac Muscles are only found in the heart wall of vertebrates. Skeletal Muscles can be found all over the body, attached with the help of Tendons.
