Although they are both striated muscles, that is the biggest thing they have in common. The skeletal muscle is controlled by the somatic nervous system, while the cardiac muscle is not. In fact, it is involuntary, therefore without a control center. Another difference is where they are located in the body.

Step-by-step answer
P Answered by PhD 51
The mentioned characteristics of the Cardiovascular system in this exercise are:
- One nucleus
- Striated
- Involuntary
- Intercalated Disks
Explanation:
All right, let's explain why all those characteristics are from the cardiovascular system.
First of all, the majority of the cardiovascular cells are build by only 1 nucleus. therefore, TThe cardiovascular system alls into the first one nuclei characteristic. Second, the cardiovascular system is managed involuntarily because we don't decide how to pump the blood and distribute it in the body, also it is controlled by the medulla oblongata in the brainstem right under the hypothalamus. These parts of the brain control the involuntary functions of our body. The cardiovascular tissue is also striated because its organization is defined by the I, and A bands which are layers of cell constituted by different proteins which provide them different colors. granting it the striated appearance. Finally, it also looks like an intercalated disk because the cells that build the cardiovascular tissue are inside collagen fibers and other substances so it can develop it's contraction movements.

why the daughter cells resulting from mitosis are genetically identical to each other and to the original cell.
Step-by-step answer
P Answered by PhD
Answer and explanation: Mitosis is an indirect cell division, the most common way of reproduction of eukaryotic cells. The biological significance of mitosis lies in the strictly equal distribution of chromosomes between daughter nuclei, which ensures the formation of genetically identical daughter cells and maintains continuity in a number of cell generations. The daughter cells resulting from mitosis are genetically identical to each other and to the original cell because they are exact copies of the chromosomes of the father cell.

What processes do the kelp perform to make their food molecules and break them down for energy ?
Step-by-step answer
P Answered by PhD 1
Answer: photosynthesis, using sunlight, water, carbon dioxide, or other chemicals
Explanation: Photoautotrophs include green plants, algae, cyanobacteria, etc. In the process of photosynthesis, with the help of special pigments, they absorb light energy and convert it into the energy of chemical bonds of organic substances. The starting material for the synthesis of organic compounds are inorganic substances such as carbon dioxide and water. Thus, photosynthesis is the process of formation of organic substances from carbon dioxide and water, proceeding with the absorption of light energy with the participation of photosynthetic pigments. In plants and algae, photosynthesis takes place in chloroplasts: the light phase is on the membranes of thylakoids and only in the light, the dark phase is in the stroma, regardless of the presence of light. In the light phase, light is absorbed by pigments, photolysis of water, synthesis of ATP and reduction of NADP. One of the products of this phase is oxygen released into the environment.

FAQs
What is a characteristic of cardiac muscle that is not true of skeletal muscle? ›
Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility. However, unlike skeletal muscle, cardiac muscle is under involuntary control. The cardiac muscle is responsible for the contractility of the heart and, therefore, the pumping action.
What characteristic differentiates cardiac muscle from skeletal muscle? ›Cardiac muscle differs from skeletal muscle in that it exhibits rhythmic contractions and is not under voluntary control. The rhythmic contraction of cardiac muscle is regulated by the sinoatrial node of the heart, which serves as the heart's pacemaker.
Which of these characteristics applies to cardiac muscle but not to skeletal muscle? ›Like skeletal muscle, cardiac muscle is striated, but unlike skeletal muscle, cardiac muscle cannot be consciously controlled and is called involuntary muscle. It has one nucleus per cell, is branched, and is distinguished by the presence of intercalated disks.
What is the main difference between cardiac muscle and skeletal muscle quizlet? ›how do cardiac muscles differ from skeletal muscle cells? Cardiac muscle is involuntary and found only in the heart. Cardiac muscle is striated, but the bundles are connected at branching, irregular angles called intercalated discs. Skeletal muscle is striated in regular, parallel bundles of sarcomeres.
What is a major difference between skeletal muscle and cardiac muscle quizlet? ›Unlike skeletal muscle, cardiac muscle does not use a sliding filament mechanism for contraction. Unlike skeletal muscle, cardiac muscle is not striated. Unlike skeletal muscle cells, cardiac muscle cells can be autorhythmic.
What does cardiac muscle have that skeletal muscle does not? ›One other distinct feature of cardiac muscle fibers is that they have their own auto rhythmicity. Unlike smooth or skeletal muscle which require neural input for contraction, cardiac fibers have their own pacemaker cells like the sinoatrial (SA) node that spontaneously depolarizes.
What is the difference between skeletal muscle smooth muscle and cardiac muscle? ›Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
What is a unique characteristic of cardiac muscle? ›One feature unique to cardiac muscle is the presence of intercalated discs. These were originally believed to be another type of striation or stripe. From studies of these bands with the electron microscope it can be seen that these discs represent the end-to-end junction of adjacent cardiac muscle cells.
What is not a difference between cardiac and skeletal muscle? ›Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility. However, unlike skeletal muscle, cardiac muscle is under involuntary control. The cardiac muscle is responsible for the contractility of the heart and, therefore, the pumping action.

What are 3 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.
What are the major structural differences between cardiac and skeletal muscle tissues? ›While skeletal muscle consists of parallel linear fibers, the cardiac muscle cells (cardiomyocytes) are arranged in fibers exhibiting cross-striations formed by alternating segments of thick and thin protein filaments.
What is one major difference between the action potential of skeletal muscle and the cardiac muscle? ›One major difference is in the duration of the action potentials. In a typical nerve, the action potential duration is about 1 ms. In skeletal muscle cells, the action potential duration is approximately 2-5 ms. In contrast, the duration of cardiac action potentials ranges from 200 to 400 ms.
What are the differences between cardiac and skeletal muscle in terms of histology and physiology? ›Skeletal muscle is striated. That is, it has an alternating pattern of light and darks bands that will be described later. Cardiac muscle cells are not as long as skeletal muscles cells and often are branched cells. Cardiac muscle cells may be mononucleated or binucleated.
Which of the following statements is true of cardiac muscle and not skeletal muscle? ›The correct answer is (c) cells are connected to one another by intercalated discs.
How is cardiac muscle structurally different from smooth muscle? ›smooth muscle cells are fusiform-shaped(spindle like shape), but cardiac muscle cells are long and cylindrical.
What is the difference between skeletal muscle and cardiac muscle histology? ›Cardiac muscle is striated, like skeletal muscle, as the actin and myosin are arranged in sarcomeres, just as in skeletal muscle. However, cardiac muscle is involuntary. Cardiac muscle cells usually have a single (central) nucleus. The cells are often branched, and are tightly connected by specialised junctions.
What are two unique characteristics of cardiac muscle relative to skeletal muscle? ›Cardiac muscle cells are much smaller (10–20 μm in diameter and 50–100 μm in length) in comparison to skeletal muscle cells. Also unique to the cardiac muscle are intercalated discs that connect cardiac muscle cells to each other.
Which characteristic is unique to cardiac muscle quizlet? ›Cardiac muscle is often branched. Which characteristic is unique to cardiac muscle? The answer is B. In smooth muscle calcium released by the smooth ER initiates contraction by binding to calmodulin.

Which characteristic differentiates skeletal muscle from both cardiac and smooth muscle? ›
Skeletal muscle is voluntary and striated, cardiac muscle is involuntary and straited and smooth muscle is involuntary and non-striated.
How to tell the difference between skeletal and cardiac muscle histology? ›Skeletal muscle is striated. That is, it has an alternating pattern of light and darks bands that will be described later. Cardiac muscle cells are not as long as skeletal muscles cells and often are branched cells. Cardiac muscle cells may be mononucleated or binucleated.
What is the main difference between an action potential in cardiac muscle and skeletal muscle? ›One major difference is in the duration of the action potentials. In a typical nerve, the action potential duration is about 1 ms. In skeletal muscle cells, the action potential duration is approximately 2-5 ms. In contrast, the duration of cardiac action potentials ranges from 200 to 400 ms.
What is the characteristic only of cardiac muscle? ›One other distinct feature of cardiac muscle fibers is that they have their own auto rhythmicity. Unlike smooth or skeletal muscle which require neural input for contraction, cardiac fibers have their own pacemaker cells like the sinoatrial (SA) node that spontaneously depolarizes.
What is the only characteristic feature of cardiac muscle? ›Cardiac muscles are specialized muscle cells in the heart that are slightly striated and have a single nucleus in the centre of the cell. It particularly aids in the blood pumping action of the heart. Cardiac muscles are branched, which is their unique feature.
What are three major differences between skeletal smooth and cardiac muscle tissue? ›Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
