What else can I help you with?
Increasing the number of active motor units is called?
Muscle recruitment
What in muscle cells increase as a result of exercise?
Muscle cells increase in size (hypertrophy) and in number of mitochondria, which are responsible for producing energy. Additionally, exercise can lead to an increase in the concentration of myoglobin, which helps store and transport oxygen in the muscles.
When a muscle grows in size what name do we give to the muscle growth?
When muscles grow in size we call this hypertrophy.The word hypertrophy actually refers to an increase in the size of an organ due to an increase in the size of the cells, rather than to an increase in the number of cells. Other body tissues can actually undergo hypertrophy, such as the heart or kidneys (this is usually a bad thing). To differentiate, we usually refer to muscle growth as muscle hypertrophy, but the term is so often applied to muscle building that this is usually not necessary in lay discussions.Increases in size due to an increase in the number of cells (cell proliferation, by the way, is called hyperplasia.
Do muscle cells expand?
Muscle cells can increase in size through a process called hypertrophy, which typically occurs with resistance training or increased physical activity. This enlargement results from the synthesis of more proteins, leading to larger muscle fibers. However, muscle cells do not "expand" in the sense of stretching; instead, they grow by increasing their mass and volume. Additionally, muscle cells can also increase in number through a process called hyperplasia, although this is less common in humans.
Why must one expect to see a larger number of mitochondria in muscle cells?
Mitochondira generate a cells fuel, called adenosine triphosphate (ATP), which is used as a source of chemical energy, which you need because muscle cells are so active.
What do you call the increase in the number of motor units activated when the intensity of stimulation increases?
The increase in the number of motor units activated when the intensity of stimulation increases is called recruitment. It allows the body to generate more force by involving additional motor units to contract muscle fibers.
Why do cardiac muscle cells have a large number of mitochondria?
Cardiac cells are very active. A lot of energy is needed
How does HGH contribute to muscle growth?
Human Growth Hormone (HGH) stimulates the growth and repair of muscle tissue by promoting protein synthesis and increasing the number of muscle cells. This leads to an increase in muscle mass and strength.
What is it called when a cell increase in size or number?
Hypertrophy
What is multiple motor unit summation or recruitment in a muscle?
When a greater number of motor units are present in a muscle and are able to be simultaneously stimulated causing an increase in muscle force (Sherwood, and Kell 271-272).
What supplements can increase muscle mass?
Protein supplements such as "Muscle Milk" or protein powder in addition to doing weigh lifting (high weight with a low number of repetitions).
Which cells in your body would have a large number of mitochondria?
Metabolically very active cells. Examples are cardiac and muscle cels
