What are the special features of a skeletal muscle cell?
Muscle cells have several different features that they all share. First off, they all have DNA. Secondly, they are all myofilaments.
The fastest a muscle fiber can contract is 0.01 seconds or less. However, this is not necessarily the speed that the actual muscle contracts at. For example, the human eyelid can only blink in 0.15 seconds.

What is calcium buildup in shoulder muscles?
Calcific tendonitis refers to a build-up of calcium in the rotator cuff (calcific deposit). When calcium builds up in the tendon, it can cause a build up of pressure in the tendon, as well causing a chemical irritation. This leads to pain. The pain can be extremely intense. It is one of the worst pains in the shoulder (the other being Frozen Shoulder ). In addition to the chemical irritation and presssure, the calcific (calcium) deposit reduces the space between the rotator cuff and the acromion, as well as affecting the normal function of the rotator cuff. This can lead to subacromial impingement between the acromion and the calcium deposit in the rotator cuff when lifting the arm overhead.
What is the difference between a tooth and a bone?
Enamel is developed during infancy and adolescence only. Once the tooth has erupted into the mouth, no more enamel is created. Enamel has no innervation and no blood supply. In short, it is not living tissue, and cannot be healed if broken by trauma or disease (tooth decay).
In contrast, bone tissue has blood supply and innervation. It continues to replace it's worn out cells throughout life, and it is capable of healing if damaged through injury or disease.
Compare slow oxidative to fast glycolytic muscles fibers?
Slow twitch: These muscle fibers are also known as Type 1. Slow twitch muscle fibers are generally fatigue resistant and have a high capacity for aerobic energy supply, but they have limited potential for rapid force development. They are red because all of the blood that goes through them due to their high level capillarizention. They are not easily injured and they can handle extreme amount of work and do not fatigue easily. Slow twitch muscle fibers rely on oxygen as their main energy source. These muscle fibers contract slowly and can be used for longer periods of time before they fatigue. Therefore, slow twitch fibers are great at helping athletes run marathons and bicycle for hours.
Fast glycolytic: Fast glycolytic or Type 2b are also fast twitch white muscle fibers but these muscle fibers have a very low tolarance to fatigue and need a high period of recovry after use. However, they are extremely powerful and explosive fibers and are the ones involved in activities like power lifting, the pitch of a baseball, javelin throwing, shot putting, the beginning of a sprint, etc.
What is the the a pair of two muscles that work together?
You can begin a muscle strengthening regimen by having push days and pull days. Push days include any muscle group that causes you to push weight away from you body..leg press...triceps...chest...quadriceps....pull days are when weight is brought towards your body...biceps...hamstrings...back....these will keep the proper 48 hours between muscle groups and allow for muscle development to occur smoothly
How do you heal a butt strain?
If on the skin of your buttocks, put Neosporin and a band aid on it. It should heal within 5-7 days if a small cut. If you mean inside the anal canal, you may need a cream prescription medication to help the tear or cut heal.
Which of the following muscles has no direct role in flexing the forearm at the elbow?

What is the removal of fibrous membrane tissue separating muscle?

What muscles do you work when you do lunges?

The muscles of the arm are what to the skin of the arm?
The muscles of the arm are natural tighteners to the skin of the arm
In terms of the nervous system, muscles and glands are given the generic term effector organs. Impulses are picked up from receptors, which then travel to the brain, which sends orders along the motor neurons to these effector organs. In the case of reflex actions, however, the brain is not involved, and the process is done much faster as a result.
