Which type of muscle has very little mitochondria?
Mitochondria is the organelle that provides energy in the form of A.T.P. (adenosine-tri-phosphate) so the muscle cell that has the fewest mitochondria must be the muscle cells that do not require much energy like the muscles of the head etc.Type your answer here...
How much should you run everyday?
How much you run everyday depends on your goals and your body. If you are training for a marathon, you may run a few miles a day for awhile, but if you have sore joints it might be healthier to not run at all.
One of four long digits at the end of an arm AND a small steel device used in joining wood piece?
I think it is referring to nails, but the wording is a bit off.
What kind of jab are you talking about? I think perhaps you need to be clearer.
Why might your shoulder pop or be out of place?
It could be gas buildup between the joints, which is natural, but if it really hurts i would get it checked out.
Why are some muscles called voluntary and involunary?
The somatic nerves control the voluntary cells which are under conscious control. If you want to walk, and do so, this is a voluntary motion. The autonomic nerves control the involuntary motions of your body. These nerves keep check of your body by maintaining temperature, composition of blood, heart beat, digestion, and excretion. These are actions that you do not think about. Even stress when your blood pressure, pulse rate, and blood sugar become elevated, is controlled by the autonomic nerves. The somatic and autonomic systems work together. Skin exposed to cold air becomes "blue," this is autonomic. At the same time impulses are sent to the brain for sensations of cold, this is somatic.
How is smooth muscle significantly different from striated muscle?
Smooth muscle shortens and stretches to a greater extent than does striated muscle.
What is classified as a skeletal muscle relaxant and an antianxiety medication?
Benzodiazepines, especially valium.
What happens if cardiac muscles do not contract?
You would get a heart attack otherwise known as a cardiac arrest.
Do you have to stay overnight for rotator cuff surgery?
Yes, you would be under a general anesthesia.
They are in your upper arm
No. It's in your lower arm.
Who has the worlds largest bicep?
Gregg Valentino is credited as having the world's largest biceps. He started bodybuilding at the age of 13 and his body responded extremely rapidly. By the time he was in his late teens he had already developed an outstanding physique at only 160lbs with 18 inch arms. Gregg claims after 23 years of training naturally he decided to experiment with steroids. During this time his arms grew from an impressive a natural 21" to an enhanced 28".
What grows first puberty muscles or bones?
Bone grow first, as it develops your height, then your muscle.

Starting with the release of acetylcholine what are the steps in muscle contraction?
Acetylcholine released by the motor neuron at the neuromuscular junction changes the permeability of the cell membrane at the motor end plate. The permeability change allows the influx of positive charge, which triggers an action potential. The action potential spreads across the entire surface of the muscle fiber and into the interior via T tubules. The cytoplasmic concentration of calcium ions (released from the sarcoplasmic reticulum) increases, triggering the start of a contraction. The contraction ends when AChE removes the ACh from the synaptic cleft and motor end plat
What are the muscles used in cricket?
Muscles associated with bowling (cricket).
Contrary to popular belief (and what has previously been mentioned on this site), bowling a cricket ball involves only a few primary muscles - but numerous of supporting and auxiliary muscles.
The main muscles required to generate the majority of force when bowling a cricket ball (with a relatively standard action) are:
-The Pectorals (A.K.A: Pecs/Chest): These muscles provide the primary frontal pull of your arm as it rotates over your shoulder. (Stand facing a wall and swing your arm over your head slowly, as if you were bowling, and press against the wall without bending your arm - you will feel your pecs flex).
-The Latissimus Dorsi (A.K.A: Lats): Provided the forward and downward pull of your arm.
-The Deltoids: Provide the upwards lift of your arm and the anterior head provides some forward pull as well.
-The Trapezius (A.K.A: Traps): Provide upward and inward lift/pull of arm.
-The Abdominals and Obliques (A.K.A: Abs): Provide the downward pull of your body that is essential for the thrust created by bending your torso (doubling over) as the ball is released.
***
However, whilst bowling a multitude of auxiliary muscles contribute to your actions. Although these muscles are far too numerous to be named entirely, some of the more major auxiliary muscles include: The biceps, wrist flexors, Teres major/minor (very important - could be considered primary) and the other numerous muscles classed as "rotator cuff".

Now, many of you are probably thinking: "Why hasn't he mentioned any "leg" muscles?" This is simply because you do not "bowl" with your legs. Yes you have to run in on your legs and yes they contribute majorly to bowling, but bowling is - in its purest form - an upper torso/shoulder action. Thus, "Leg" muscles are considered as 'supporting' muscles.
These supporting muscles include:
-Quadriceps, Gluteus Maximus, Hamstring, Calf (Gastrocnemius and Soleus): These muscles are included in one, as these are the main muscle groups that attribute to running/jumping speed and power.
-Errector Spinae: Supports your back (extends), thus provides ability effectively use your core muscles during bowling and the ability to bend-back before bowling.
-Core Muscles (asides from those aforementioned): Provide stability to entire body throughout action.
***
-Training these muscles:
In order to bowl effectively, it is essential that all of these muscles are strong and fit. To achieve this is ALL muscles through the use of a gym is impractical - thus, the best way to improve the condition of these muscles is to simply bowl.
However, it is vital that some muscles are strengthened through use of weight training to significantly improve power and ultimately bowling speed. Therefore, I would recommend using weights to increase the strength of the "main" muscles I listed in the first section (I would also recommend strengthening some of the "supporting" muscles to a lesser degree in order to resist injury and further enhance your "main" muscles.
By using the internet you can easily discover numerous exercises designed to strengthen the muscles listed I have recommended. If you conduct regular exercise, engaging these muscles over a period of 6-8+ weeks - obvious improvements will be felt and many of the "auxiliary" muscles will be strengthened as well.
***
-NOTE:
You may be wondering why I have not focused heavily on arm muscles, notably, the biceps and triceps. This is because when bowling you are not allow to bend your arm! The biceps bend your arm and the triceps straighten your arm. Thus, the biceps are used minimally and only really after the ball has been bowled and a small bend occurs in the arm to provide whip (auxiliary). The triceps keep the arm straight throughout the action, so they could be listed as "supporting" but they contribute so minimally that I excluded them.

Thankyou for reading this in depth analysis into the muscles associated with bowling (cricket). This guide is aimed to help fast bowlers recognise what muscles they are using and ways they can strengthen them - although this guide may also help bowlers of other disciplines as well.
Enjoy your cricket, and remember - Modern technology makes perfect!

What muscles do you use when you are running?
All the muscles of your leg work when you run.
Quadriceps and Hamstrings (Thighs) and Calf muscles work the most. Apart from this your glutes (butt) muscles work a fair bit too.
Also while running we tend to move our arms and shoulders and hence your deltoids (shoulder) muscles work too.
What is the structure that alters the shape of the lens for accommodation?
It automatically adjusts its thickness to focus the light.
Exercise demands energy.Our muscle cells produces instant energy by breaking down ATPs,otherwise known as energy coins inside a living system.Which can be utilized at the time of need.Energy in turn could only be incorporated to ATPs by burning or biologically oxidating the primary food stuffs,which requires oxygen.The mitochondria in a living cell can generate a good lot of ATPs aerobically(presence of oxygen) by breaking down sugars vide TCA cycle & electron transport chain.But when oxygen is scarce as during exercise,the system adapts a different strategy to produce energy. It goes through an anaerobic(absence of oxygen) path called glycolysis.The energy produced (ATPs generated) in later is comparatively less then the former.And to add to the sequence,another side effect of accumulation of lactic acid occurs.Accumulation of which accounts for muscle fatigue,which we all experiences after a hectic sports schedule is over.We take long gasping breathes to wash lactic acid out & oxygen in to come back to normalcy again.
