What else can I help you with?
What will happen if only 1 muscle is used to bend and straighten the arm?
Two muscles are needed, one to extend the other to close
Is cardiac muscle multinucleate or uninucleate?
It is uninucleate not because it has one cell, but because each cell in that muscle has 1 nucleus.
How many muscles work together move one bone 1 2 3 or 4?
Typically, two or more muscles work together to move a single bone. Muscles operate in pairs: one muscle contracts while the other relaxes to facilitate movement. For example, when bending the elbow, the biceps contract while the triceps relax. This coordinated action allows for smooth and controlled movement.
What is the fast muscle in the human body?
The retinal muscle group, (can change positions in 1/128 of one second).
How long are ahl contracts?
AHL contracts are usually 1 year but can be as long as NHL contracts usually depending on how old or what team the player is drafted too.
Which muscle cells have multiple nuclei?
The type of muscle tissue that have only one or two nuclei per cell are cardiac muscle cells. Their nuclei are located in the center of a cell.
What is nuclei in the skeletal muscle?
Skeletal muscles (the ones in arms, legs and other moving parts of the body) have large numbers of nuclei. They are formed during development by the fusion of many single nucleus myoblastcells . Other muscle cells, like the cardiac muscle cells in the heart or smooth cells in the gut, do not fuse and have only one nucleus. For more information see "Molecular Biology of the Cell" published by Garland Press.
The calf is made of what two major muscle?
The 2 Main muscles are: (1.) Gastrocnemius is the muscle on the back of your calf, as well as the (2.) soleus muscle which lies under the gastrocnemius muscle. (The tibalis anterior and peroneus longus are also calf muscles.)
The different types of muscle tissue differ from each other by?
1) Whether they have striations2) Whether they are voluntary or involuntary3) Whether they are uninucleate (single nucleus) or multinucleate (more than one nucleus)
Muscle weighs more than fat but how much more?
"...One liter of muscle would weight 1.06 kg (1060 grams) and one liter of fat would weight 0.9 kg (900 grams). In other words, muscle is about 18% denser than fat. ..." Interestingly, 1 litre of water weighs 1 kg. So muscle weighs more than water.
What is the difference between visceral muscle and skeletal muscle?
1) skeletal muscle is voluntary 1) visceral muscle is involuntary 2) it is striated . 2) it is non striated 3) highly organized muscle. 3) less organized muscle
How is smooth muscle and cardiac muscle different from skeletal muscle?
Cardiac muscle is a type of involuntary striated muscle found in the walls and histologic foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. The cells that comprise cardiac muscle, called myocardiocyteal muscle cells, are mononuclear, like smooth muscle cells.[1]Coordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems. This complex of actions makes up the systole of the heartSkeletal muscle is a form of striated muscle tissue existing under control of the somatic nervous system. As its name suggests, most skeletal muscle is attached to bones by bundles of collagen fibers known as tendons.Smooth muscle is an involuntary non-striated muscle. It is divided into two sub-groups; the single-unit (unitary) and multiunit smooth muscle. Within single-unit smooth muscle tissues, the autonomic nervous system innervates a single cell within a sheet or bundle and the action potential is propagated by gap junctions to neighboring cells such that the whole bundle or sheet contracts as a syncytium (i.e., a multinucleate mass of cytoplasm that is not separated into cells). Multiunit smooth muscle tissues innervate individual cells; as such, they allow for fine control and gradual responses, much like motor unit recruitment in skeletal muscle.
