Both actually. For the most part, a region in your brainstem called the medulla oblongata regulates the rhythm of your breathing automatically and therefore involuntarily. You are, however, able to temporarily override that system by taking a larger breath than normal or forcibly exhaling your expiratory reserve or even holding your breath for a limited amount of time. The automatic system will always win out in the end forcing you to take a breath no matter how hard you try not to.

Which muscle type can voluntarily contract and relax?
Skeletal muscles .
Which of these are tissues that can relax and contract?
Smooth muscle tissues can relax and contract. Additionally, cardiac muscle tissues also have the ability to relax and contract. Skeletal muscle tissues are another type that can relax and contract voluntarily.
Why do we get muscle cramps and what are the possible causes behind them?
Muscle cramps occur when muscles contract involuntarily and do not relax. Possible causes include dehydration, electrolyte imbalances, muscle fatigue, poor circulation, and certain medical conditions.
What causes a cramp to occur in the body?
A cramp occurs in the body when muscles contract involuntarily and do not relax properly. This can be caused by dehydration, muscle fatigue, lack of stretching, or mineral imbalances.
What is the physiology behind muscle cramps?
Muscle cramps occur when muscles contract involuntarily and do not relax. This can happen due to various reasons such as dehydration, muscle fatigue, or electrolyte imbalances. When a muscle cramps, the normal communication between the nerves and muscles is disrupted, causing the muscle to contract and stay contracted. This can lead to pain and discomfort until the muscle relaxes.
What is the organ system composed of tissue that can relax and contract?
The organ system composed of tissue that can contract and relax is muscle tissue.
What is happening at the cellular level during a muscle cramp?
During a muscle cramp, the muscle fibers contract involuntarily and do not relax. This is often caused by an imbalance of electrolytes like calcium and potassium, which are essential for muscle function. The excessive firing of nerve signals can also contribute to muscle cramps.
What are the following are tissues that can relax or contract?
The primary tissues that can relax or contract are muscle tissues, which include skeletal, cardiac, and smooth muscle. Skeletal muscle enables voluntary movements, while cardiac muscle contracts involuntarily to pump blood. Smooth muscle is found in organs and blood vessels, facilitating involuntary movements such as digestion and blood flow regulation. These tissues work together to enable various bodily functions through contraction and relaxation.
What muscle is slow to contract and relax?
cardiac
Which cells have long fibers that can contract and relax?
Muscle cells can contract and relax and lave fibers as long as 1.5 feet.
What is the function of muscular tissue?
Well, skeletal muscle (the kind you can contract voluntarily) is used to move your bones and help you move, keep your posture, etc. Smooth muscle on the other hand has numerous functions such as the relaxation and constriction of blood vessels or in peristalsis in the gastrointestinal tract.muscular tissue helps in movements of different body parts by working antagonistically . they are attached to bones and when they contract and relax, bones move.
What is The organ system composed of tissue that contract and relax?
The organ system composed of tissue that can contract and relax is muscle tissue.
