How many types of muscles in human body are not under voluntary control?
There are two types of muscles which are NOT under your control. They are smooth muscles present in many tubular organs present in your body. Second type is present in heart called as cardiac muscles.
What are the only two types of cells that have excitable membranes?
The only two types of cells that have excitable membranes are neurons and muscle cells. Neurons transmit electrical signals in the nervous system, while muscle cells generate electrical signals that lead to muscle contraction.
What are the two contractile proteins of muscle?
The two contractile proteins of muscle are actin and myosin. Actin is a thin filament, while myosin is a thick filament. They interact with each other to generate the force required for muscle contraction.
What muscle actions would be classified as isotonic contractions?
Isotonic contractions involve muscle actions where the muscle length changes as it contracts against a constant load. There are two types: concentric contractions (shortening of the muscle during contraction) and eccentric contractions (lengthening of the muscle during contraction).
What are the differences between the two types of protein and how do they impact muscle growth and recovery?
There are two main types of protein: fast-digesting and slow-digesting. Fast-digesting proteins like whey are quickly absorbed by the body, making them ideal for post-workout muscle recovery. Slow-digesting proteins like casein release amino acids slowly, providing a steady supply for muscle growth and repair throughout the day and night. Both types of protein are important for muscle growth and recovery, but the timing of consumption can impact their effectiveness.
Which types of muscles are involuntary?
Of the three types of muscle, the two that are involuntary are cardiac muscle and smooth muscle.
What are the two muscle types?
One type of muscle is called smooth muscle. A smooth muscle works involuntarily. The other type of muscle is called skeletal muscle. Skeletal muscle only works with a command.

Uncontrolled muscle contractions the same as skeletal muscle contractions?
Uhh, no uncontrolled muscle contraction occurs in smooth and cardiac muscles... there are many differences between these two types of muscles; controlled and uncontrolled muscle contraction.....
Types of muscle are involuntary?
Of the three types of muscle, the two that are involuntary are cardiac muscle and smooth muscle.
Are voluntarily controlled by skeletal or cardiac or smooth?
Voluntary muscles are controlled by the skeletal muscle system, while cardiac and smooth muscles are involuntary and regulated by the autonomic nervous system. Skeletal muscles are under conscious control for movement, posture, and facial expressions, while cardiac muscles control the heart's contractions and smooth muscles regulate internal organ functions.
Compare and contrast the three types of muscles?
There are three types of muscle tissue found in the human body. There are visceral muscles, which consist of smooth muscle tissue, which is controlled by the autonomic nervous system and responds to both hormones and neural stimulation. Smooth muscles have no striations, as the nucleus is centrally located. Thus, they are involuntarily controlled. Then, there is cardiac muscle, which is only found in the heart and is also stimulated by neural activity and hormones. Lastly, there are skeletal muscles, which aid in the movement of the body and is mostly attached to bones by means of tendons. These muscles are striated, and are voluntarily controlled. Skeletal muscles can further be sub-divided into two categories: red and white muscles. Red skeletal muscle tissue consists of a chemical not found in the white skeletal muscle called myoglobin. Myoglobin is a protein-like molecule, which aids in the storage of oxygen, which is essential to its function. Thus, this extra molecule is responsible for giving red muscles their coloring.
Are there times when skeletal muscle function involuntarily?
Absolutely. Some examples include shivering, muscle spasms, muscle cramps, changing body positions during sleep, and breathing (which is voluntary up to a point, then it happens involuntarily to keep you from dying). There are also two different skeletal muscles in your middle ear that are completely under autonomic (involuntary) control.
What muscle is controlled by two nerves?
All of them....or do you mean the autonomic nervous system?
Muscle sphincters are composed of what two types of muscle fibers?
Smooth Muscle Fiber
What are three different muscle types?
There are three types of muscle tissue found in the human body. There are visceral muscles, which consist of smooth muscle tissue, which is controlled by the autonomic nervous system and responds to both hormones and neural stimulation. Smooth muscles have no striations, as the nucleus is centrally located. Thus, they are involuntarily controlled.

What are two types of scientific investigations that scientist use when a controlled experiment is not practical?
When a controlled experiment is not possible or practical, two types of scientific investigations are observation and modeling.
