What else can I help you with?
Which muscle contract about 70 times a minute?
cardiac muscle
What muscle is slow to contract and relax?
cardiac
What muscle can contract without the need for the nervous stimulation?
Smooth & cardiac muscle.
Which type of muscle can contract without being stimulated by the nervous system?
cardiac muscle tissue
What type of muscle tissue makes up wall of heart?
Cardiac muscle tissue forms the walls of the heart.
How is cardiac muscle similer to both smooth and skeletal muscle?
All of them contract to perform the specific functions.
Which type of muscle is the heart made of?
cardiac
What characteristic does not describe cardiac muscle tissue?
Cardiac muscle tissue is specifically muscle tissue of the heart. It is smooth just like skeletal muscle tissue but has special characteristics that help it to contract at fast, steady rates.
What type of muscle tissue has a gap junction?
Cardiac muscle tissue has gap junctions to allow impulses to travel quickly though the tissue so the two atria can contract as one and the two ventricles can contract as one.
What is the function of a cardiac cell?
Cardiac cells are muscle cells that make up the heart (cardiac tissues). When the muscles contract, they force blood out of the ventricles of the heart.
How does the contraction mechanism of smooth muscle compare to that of skeletal muscle and cardiac muscle?
Smooth muscle, skeletal muscle, and cardiac muscle all contract in response to signals from the nervous system or hormones. However, the contraction mechanism of smooth muscle is different from that of skeletal and cardiac muscle. Smooth muscle contracts more slowly and can sustain contractions for longer periods of time compared to skeletal and cardiac muscle. Additionally, smooth muscle does not have striations like skeletal and cardiac muscle, which gives it a more uniform appearance.
Which type of muscles causes the heart to contract and relax?
auto-rhythmic cardiac muscle
