How does striated visceral muscles differ from striated cardiac muscles?
it has a different embryonic origin - it is neither cardiac nor skeletal muscle. it is often found in the head and neck.
How do skeletal and cardiac muscles differ?
cardiac is uni/binucleate, has intercalated discs, and is has branching fibers, skeletal is multinucleate and is long and cylindrically shaped.Skeletal muscle is found in the arms and legs and also other parts of your body. For skeletal muscle to contract it needs to be independly stimulated by a nerve ending. Cardiac muscle is a involantry muscle within the heart which automaticly contracts because of its self- excitable cells. It is a muscle which does NOT produce lactic acide ( normally) and it does not need a nerve to stimulate it to contract
How cardiac muscle fibers differ from the fibrs of skeletal muscle?
Both cardiac and skeletal muscle cells are striated and contract by the sliding filament mechanism. However, cardiac muscles cells are short, fat, branched, and interconnected unlike the long, cylindrical, multinucleate of skeletal muscle fibers.
What are the three types of muscles and how do they differ in terms of structure and function?
The three types of muscles are skeletal, smooth, and cardiac muscles. Skeletal muscles are attached to bones and are responsible for voluntary movements. They have a striped appearance due to their organized structure of muscle fibers. Smooth muscles are found in organs and blood vessels, and they are responsible for involuntary movements. They have a smooth appearance and are not under conscious control. Cardiac muscles are found in the heart and are responsible for pumping blood throughout the body. They have a unique branching structure and can contract rhythmically without fatigue.
In what three ways can muscle cells be classified?
Muscle cells can be classified based on their structure as either skeletal, smooth, or cardiac muscle cells. These types of muscle cells differ in their appearance and function. Skeletal muscles are attached to bones and help with voluntary movements, smooth muscles are found in the walls of organs and blood vessels, and cardiac muscles are unique to the heart.
How are the muscular and the skeletal systems different?
The muscular system is made up of muscles, the Skeletal system is made up of bones
What are the three different types of muscle found in the human body?
Cardiac muscle tissue forms the bulk of the wall of the heart. Like skeletal muscle tissue, it is striated (the muscle fibers contain alternating light and dark bands (striations) that are perpendicular to the long axes of the fibers). Unlike skeletal muscle tissue, its contraction is usually not under conscious control (involuntary). Smooth muscle tissue is located in the walls of hollow internal structures such as blood vessels, the stomach, intestines, and urinary bladder. Smooth muscle fibers are usually involuntary (not under conscious control), and they are nonstriated (smooth). Smooth muscle tissue, like skeletal and cardiac muscle tissue, can undergo hypertrophy. In addition, certain smooth muscle fibers, such as those in the uterus, retain their capacity for division and can grow by hyperplasia. Skeletal muscle tissue is named for its location - attached to bones. It is striated; that is, the fibers (cells) contain alternating light and dark bands (striations) that are perpendicular to the long axes of the fibers. Skeletal muscle tissue can be made to contract or relax by conscious control (voluntary). All skeletal muscle fibres are not alike in structure or function. For example, skeletal muscle fibres vary in colour depending on their content of myoglobin (myoglobin stores oxygen until needed by the mitochondria). Skeletal muscle fibers contract with different velocities, depending on their ability to split Adenosine Triphosphate (ATP). Faster contracting fibers have greater ability to split ATP. In addition, skeletal muscle fibers vary with respect to the metabolic processes they use to generate ATP. They also differ in terms of the onset of fatigue. Based on various structural and functional characteristics, skeletal muscle fibres are classified into three types: Type I fibres, Type II B fibres and type II A fibers.
What type of cells does the heart have?
The heart contains cardiac muscle cells. The cells are striated (the muscle fibers contain alternating light and dark bands). They differ from skeletal muscle in that it is an involuntary contraction, but they are similar in that they both have striations.
What are the differences between smooth muscle and striated muscle in terms of their structure and function?
Smooth muscle and striated muscle differ in their structure and function. Smooth muscle lacks striations and is found in organs like the intestines and blood vessels, where it contracts involuntarily. Striated muscle, like skeletal and cardiac muscle, has a striped appearance and is under voluntary control. Skeletal muscle is responsible for movement, while cardiac muscle pumps blood throughout the body.
How does the appearance of smooth muscle differ from that of skeletal mucsle?
They are all in different places. Skeletal muscles are striated and are the muscles that are in voluntary control. These include biceps(arm), pectoralis major(chest) and other muscles that you can move. These muscles are striated and has many nuclei. Smooth muscles are not striated and are the muscles that are not in voluntary control. These include organs and blood vessels, excluding heart. These muscles are unstriated with one nucleus. Smooth muscles has only one nucleus. There is only one place where cardiac muscle is found: the heart. Also called myocardium, this muscle is striated and has one nucleus. Cardiac muscle also contains intercalated disc, which acts as a junction between the two muscle cells.
How does the appearance of smooth muscle differ from that of skeletal muscle when viewed with a microscope?
i need the same answer...-.-
How does chest pain associated with a respiratory disorder differ from chest pain of cardiac origin?
Cardiac pain may go along your left arm. Respiratory pain does not. I think cardiac pain is cosidered much sharper too.
