Does increased muscle density mean more myofibrils per muscle fiber?
Yes, it means that you will gain more myofibrils per muscle fiber. A muscle fiber is a muscle cell, and everybody has about the same number. When you train your muscles, they will develop more myofibrils inside the muscle cells. So you cannot change the number of muscle fibers, or cells, but you can change the number of fibers, or myofibrils, inside them. The end result is more muscle density, not more muscle cells.
What would happen if the smooth muscles in a persons body could not contract?
There are a few types of muscles. The most "important" (term used very loosely here) are the smooth muscles, they control all bodily functions that are automatic (heartbeat, digestion, ext.) if you were missing any smooth muscle, you could not survive longer than 3 weeks (for digestion) 3 minutes (heartbeat). The second type, which I am guessing you mean in the question, is skeletal muscles. If you did not have those muscles, life would be possible, but you would be like a sea sponge, food HAS to come to you, reproduction would not be possible in the manner that we are used to (it would need to be either asexual, or like plants).
What kind of cell division do brain cells go through?
Dividing cells. In the embryo, most of the cells are dividing to produce more cells, this is how the embryo grows. In the adult, most cells are past their replicative lifespan (post-mitotic) and don't divide (nerve cells, muscle cells, etc.). The cells that are still undergoing cell division in the adult are stem cells or their progeny, often called transit amplifying cells (both found in many locations) involved in tissue repair, replacement or regeneration.
What does the soft endoplasmic reticulum do?
Smooth Endoplasmic reticulum creates steroids and stores ions. The ion storage is important to keep the correct level of nutrients within the cell. Ion storage is like our fat cells holding on to sugars for when you need them.
In what way would having many mitochondria be beneficial to muscle cells?
The mitochondria is used for energy in the human body. Having more mitochondria would be beneficial since it would mean that the body would have more energy when needed.
What type of muscle that is involuntary and not straightened?
1. You probably mean not "striated" and the answer is smooth muscle. 2. Appendix
What muscle is controlled by two nerves?
All of them....or do you mean the autonomic nervous system?
What does the medical abbreviation VSMC mean?
Vascular Smooth Muscle Cell
What muscle tissue is found along the hallow portion of the organ?
I think you mean 'smooth' muscle (as opposed to skeletal or cardiac muscle) .
Which type of muscle tissue makes possible movement of internal organs?
Internal organs usually do not move. Unless you mean the contraction of the heart, which is composed of cardiomyocytes. If you have experienced some strange movement of other organs you should contact your doctor.
What does heart muscle mean?
Your heart is a muscle. It is also called the myocardium. The muscle cells in the heart muscle are called myocardiocytes.
What bladder sphincter is composed of skeletal muscle?
Bladder sphincter belongs to smooth muslce, smooth muscle is an involuntary tissue which mean. we cannot control it. we cannot control our gallbladder it moves automatically.
Which life process are muscle cells specialist for?
Muscles are specialized tissues evolved for movement. Smooth muscle is involved in involuntary movement found in the contraction of blood vessels, the digestive tract and the iris, and also the formation of goose bumps. Skeletal muscle is a type of striated muscle involved in voluntary movement and is the muscle we are most familiar with that allows us to move our bodies. Cardiac muscle is also a type of striated muscle, although some people use it to mean skeletal muscle only, and is involved in the contraction of the heart which is the pumping motion that moves the blood throughout the body.
What is a muscle works or moves on its own?
if by on it's own you mean subconsciously, then the heart and the diaphragm
What does auto rhythmic mean?
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
What does auto-rhythmic mean?
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
