Muscular System

tropomyosin in resting muscles. When calcium binds to troponin, it causes tropomyosin to move, exposing the binding sites on actin. This allows myosin heads to bind to actin, leading to muscle contraction.

No, skeletal muscle cells do not have glycosomes. Glycosomes are specialized organelles found in certain types of cells, particularly in protists and some parasites, where they are involved in glycolysis. Skeletal muscle cells primarily rely on mitochondria for energy production.

The prognosis for spinal muscular atrophy (SMA) varies depending on the type of SMA and the individual's specific situation. In general, SMA can lead to progressive muscle weakness and loss of motor function, potentially impacting quality of life and life expectancy. Advances in treatment, such as gene therapy, have improved outcomes for some individuals with SMA. Early diagnosis and appropriate management are crucial in optimizing outcomes for those affected by SMA.

Causes weakness and wasting of voluntary muscle in arms and legs of infants. Occurs in brain and spinal cord of body. This is caused by missing gene known as survival motor neuron gene (smn1). This gene is responsible for the production of a protein essential to motor neurons. When you are an infant you body destroys many of the neurons because as an infant you have too many. In SMA you body will not stop destroying the neurons, you body eventually becomes weak and you can not move on you own. There is no known cure.

The muscles that bring a body part toward the body are called adductor muscles. They are responsible for moving a part of the body closer to the midline.

lymphatic system is the one that is responsible of the re absorption of fluids (interstitial fluid) accumulating in the intravascular back to the circulatory system. it carries WBC (White Blood Cells) and build the bone's lymphnode. The lymph transports antigen-presenting cells (APCs), such as dendritic cells, to the lymph nodes where an immune response is stimulated. it absorbs and transports fatty acids and fats as chyle from the digestive system.

Genes help us make proteins, which are essential for carrying out various functions in the body. Proteins play key roles in growth, development, and maintaining the structure and function of cells. Genes also help determine our physical traits and can influence our susceptibility to certain diseases.

The primary muscles used for blowing are the diaphragm, intercostal muscles (between the ribs), and the muscles of the abdominal wall. These muscles work together to control the pressure and airflow needed to produce a forceful breath out.

Lactic acid is produced in cells when oxygen levels are low, as an alternative pathway to generate energy in the absence of oxygen. This process is known as anaerobic respiration or fermentation. Lactic acid fermentation helps to regenerate NAD+ to keep glycolysis running in the absence of oxygen.

Skeletal muscle is most often controlled by conscious thought.

From what I read recently is that people with blood type A shouldn't eat meat and allot of white bread or starches like rice. Type is is a thicker type of blood hence more time fir plaque build up. I know its depressing! I'm 29 years old and physically fit, and have always thought i ate pretty healthy but I was wrong. Doc says i got crazy high cholesterol, now I'm dieting.

The cerebellum regulates both. Posture is maintained by anti-gravity posture muscles, controlled by the cerebellum without conscious perception. Co-ordination of motor outputs is also controlled by the cerebellum.

umm if you mean it, the cells would probably all die in the marathon anyway because cells die in one sec, lol.

But more cells would come into your muscle, or if they didn't your arm or muscle area would go black very slowly, it would feel numb and ache a bit, and then it would fall of.

There are approximately 650 skeletal muscles in the human body but an exact number is difficult to define. The difficulty lies in the fact that different sources group the muscles differently and some muscles are not always present. There is no way to list them all or to even decide what is meant by 'major'.

Yes, there can be differences in muscle tone between dominant and non-dominant forearms. The dominant forearm is usually more developed and may have greater muscle tone due to being used more frequently for daily activities. Strengthening exercises and activities that target the non-dominant forearm can help balance out muscle tone between the two arms.

Specialization in muscle and nerve cells typically reduces their ability to reproduce compared to other types of cells in the body due to their mature and highly specialized functions. Muscle cells have limited ability to divide as they are primarily designed for contraction, while nerve cells have limited capacity for regeneration due to their intricate structures and long extensions.

Preferences for butt firmness can vary among individuals. Some people may prefer a firmer butt for reasons like aesthetics, while others may prefer a more cushiony butt for reasons like comfort. Ultimately, it comes down to personal preference and what individuals find attractive.

The stomach contains enzymes that break down protein.

Expiration is simply the amount of time that it should remain in use after opening. By the time an expiration date has been met, it is considered that the standard will be contaminated or greatly devalued.

The muscle that is primarily targeted and developed when doing sit-ups and tightening the abdominal wall is the rectus abdominis. This muscle is commonly referred to as the "abs" and is responsible for flexing the lumbar spine.

Multiple sclerosis means "many scars" on the myelin sheath of the central nervous system, and muscular dystrophy refers to muscle weakness and atrophy. Multiple sclerosis affects nerve while muscular dystrophy affects muscle. Some of the symptoms are similar, such as extreme fatigue and difficulty with movement, but MS is an autoimmune disorder that can flare and affect a different area of the CNS each time while MD is a genetic disorder that is progressive and often follows a specific pattern (areas) of muscle wasting.

With MS, disability occurs when the flares are more constant and cause permanent nerve damage to an area of the body, sometimes resulting in being blind, incontinent, wheelchair bound, or even bed ridden. With muscular dystrophy, the disability comes from the lack of stamina due to muscles wasting. Having less and less healthy muscle fibers makes the person exhausted doing simple tasks and eventually can lead to inability to lift, carry, walk, or stand. Falls can happen with both disorders, as healthy nerve and muscle are needed to balance one's body. Falling can result in a secondary disability and recovery is slow and incomplete sometimes. Both of these diseases and their sufferers need our support.

Muscular dystrophy is a group of genetic disorders that lead to progressive weakness and loss of muscle mass. This can result in difficulty with movement, breathing, and other physical functions. The severity of symptoms and progression of the disease can vary depending on the specific type of muscular dystrophy.

MD is a genetic disorders in which strength and muscle bulk slowly weakens. It is caused by incorrect or missing genetic information. Without this information you can not build or maintain healthy muscles. You slowly lose the ability to walk or even sit up right. This disease can occur at any age in a persons life and there is no known cure.

There is not any medicine prescribed for lactic acid build up. You can take motrin/ibuprofin/advil or whatever you prefer and the pain should die down. If you are a runner make sure to do a cool down run after a big workout.

to cool down; JOG about a mile and the lactic acid will settle and you will not get sore.
