A basic part of the cardiomyocyte is the sarcomere which is made mostly out of contractile proteins and the mitochondria both which help in generating a fuel molecule (adenosine triphosphate, ATP) when oxygen is present. Furthermore, there is a network of tubules (sarcoplasmic reticulum) which are full of calcium ions (Ca2+). These ions are essential for proper muscle contraction to occur. The proteins in the cell are also arranged in parallel bundles- including thick and thin filaments- which together form the physical basis for muscle contraction....The area of overlap between the filaments is darker than the rest of the cell and known as the A-band. The middle of sarcomere contains only thick filaments, as thin filaments don’t extend inward from the two ends (regions known as Z-line) of the sarcomere. The area extending in any direction from the z-lines and towards the adjacent sarcomeres is the I-band.

The cardiac muscle is constantly contracting and then relaxing and is never tired, mitochondria provides the energy needed for all this work.  ]]> 2020-10-27 01:40:51 UTC https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864111539 24tn04181 https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864211776 2020-10-27 02:42:19 UTC https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864211776 24tn04181 https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864216053 Red blood cells and cardiac muscle cells work together very closely. Red blood cells are an important element of the blood which cardiac cells pump throughout the body. Both of them together really help the body function properly and survive. ]]> 2020-10-27 02:44:50 UTC https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864216053 24tn04181 https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864217762 The cardiac muscle cell is responsible for pumping blood throughout the body.  It works to keep the heart pumping through involuntary movements. It performs coordinated contractions which allow the heart to pump blood throughout the circulatory system. The cardiac cell’s job is so significant because it is essential that blood is pumped through our body for our survival because organs and tissues need the oxygen and various nutrients it carries.

The heart is made up of three different parts. The middle layer is known as the myocardium, which is made of largely cardiac muscle cells.  Cardiac muscle cells are specifically found in the heart. They make up the atria (chambers where blood enters the heart) and ventricles (chambers where blood is collected and pumped out of the heart). If it weren’t for the cardiac muscle cells making very important parts of the heart, the heart wouldn’t receive its own blood supply then causing life-threatening problems. The heart needs oxygen and nutrients and the cardiac muscle cells make this possible. ]]> 2020-10-27 02:52:36 UTC https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864228188 24tn04181 https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864306775 Osteoblast cells aren't as important as CARDIAC CELLS. They're an unsuitable candidate. Bone cells may be responsible for the synthesis and mineralization of bone but in order to function and have cell differentiation occur they need a regular blood supply, which is exactly what the cardiac muscle cell does. PUMPING BLOOD THROUGHOUT THE BODY.

Another unsuitable candidate for the presidential cell is the epidermal cell. The epidermal cells function isn't important or big. especially when compared to the cardiac cell. The epidermal cells just make up human skin, whereas cardiac cells make up the HEART. ]]> 2020-10-27 03:47:47 UTC https://padlet.com/24tn04181/uql1ratdrg3he8yc/wish/864306775
