Question

What is the Specific Function of the Cardiac Muscle?

Answer 1

Hint: Cardiac muscle looks like striated and which is longer like tendons, which gives tight bonding between tissues and strong support to build in, capable of pumping blood consistently throughout the body.

Complete Answer:
- A muscle structurally characterised as striated, non nucleated when microscopically observed it poses a striated form basically matching to that of skeletal muscle is known as Cardiac muscle.
- Invertebrates are also called Myocardium. It also shares the features with skeletal muscle many like ultrastructural elements.
- In general, both kinds of muscle are individual muscle fibres, which contain several, substituting thick and thin contractile filaments, which give each cell type its unique striated appearances.

Core functions of Cardiac Muscle:
Cardiac muscle tissue works to keep heart pumping through uncontrolled activities. This is one feature that distinguishes it from skeletal muscle tissue, which you can control. It makes this through specific cells known as pacemaker cells, these control the contractions of your heart. The nervous system sends signals to pacemaker cells that induce them to either speed up or slow down your heart rate.

Note: The cardiac muscles appear in structured and striated formats which are like skeletal muscle. These muscles act and work to keep the heart pumping the blood throughout the body. Certain types of cardiac muscle known as pacemaker cells which control the contractions of the heart, simultaneously sends the signal to the nervous system to increase or decrease the heart rate.
