What else can I help you with?
What is the muscular portion of the cardiac wall?
The muscular portion of the cardiac wall is called the myocardium. It is responsible for contracting and pumping blood throughout the body. The myocardium is made up of cardiac muscle cells that are interconnected to allow for coordinated contraction of the heart.
What phase of the cardiac cycle is longest?
Atria Diastole is the longest (0.7sec)
Which tissue has intercalated discs?
Cardiac muscle tissue has intercalated discs, which are specialized structures that help with communication and coordination of muscle contractions in 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 muscle cells commonly branch?
the cell tissue is not in fact muscle tissue its penis tissue
What kind of tissue makes up contracting organs?
The kind of tissue that makes up contracting organs is muscle tissue: cardiac, smooth and skeletal muscle.
What contracts faster cardiac or skeletal muscle?
Cardiac. Think about it ur heartbeat is constantly contracting and releasing while ur skeletal muscle on ur arms can only go so fast
Which type of muscle is the heart made of?
cardiac
What is the specific function of the cardiac muscle?
contraction of the atria and ventricle of the heart, causes beating of heart.
What is the muscle tissue found in the heart?
Smooth cardiac muscle.
Muscle tissue that has intercalated disks?
cardiac muscle cells are joined by intercalated disks.
How do you describe the cardiac muscle?
Cardiac muscle is involuntary striated muscle. The cells of cardiac muscle have only one nucleus. The layer of the heart that contains cardiac muscle is called the myocardium.
What is the muscular portion of the cardiac wall?
The muscular portion of the cardiac wall is called the myocardium. It is responsible for contracting and pumping blood throughout the body. The myocardium is made up of cardiac muscle cells that are interconnected to allow for coordinated contraction of the heart.
Is the Cardiac muscle appears striated and is completely voluntary?
cardiac muscle is striated cardiac muscle is not voluntary
What does the cardiac muscle look like?
It depends on the type of muscle. We have three kinds, smooth, cardiac, and skeletal. The skeletal ones are called striated because they have bands that divide the smallest contracting units called sarcomeres. Skeletal muscles look much like long cords, cardiac are 'Y' or 'H' shaped, and smooth muscle are spindle shaped.
Which type of muscle tissue is autorhythmic?
cardiac muscle
What are similarities between skeletal muscle and cardiac muscle?
cardiac is cardiac and skeletal is skeletal.
