Muscular System

Some of the muscles that you cannot consciously control include your heart, your stomach, and your lower digestive organs. You are probably aware that you don't control your heartbeat directly with your mind (an organ called the "sinus node" communicates with a part of the brain that you don't "control" to pace the heart), but let me explain to you about the second two examples. You may or may not already know this, but it's not only acids that digest food in the lower digestive system, but a function known as "mechanical digestion" occurs there too. Mechanical digestion (the counterpart of "chemical digestion") is when food is literally mashed up by part of your body, such as your jaw. When food is in your stomach, or large intestines, etc., muscles in that organ expand and contract to mechanically digest your food, and all this happens without your control.

Now some muscles, such as the diaphragm, are semi-autonomous, and sometimes work under your control, and sometimes not. Your diaphragm, for example, is sometimes controlled by the conscious mind to control breathing when playing an instrument, swimming, doing breathing exercises, etc.

According to Anthony's Textbook of Anatomy and Physiology the origin is that point of attachment that does not move when the muscle contracts, and the point of attachment that does move when the muscle contracts is the insertion. Muscles and muscle groups that that directly perform specific movements are prime movers or agonists.

The external and internal oblique muscles rotate and side bend the trunk. These muscles also stabilize the spine.

Involuntary muscles are those which function without the need for conscious thought or effort. The heart beats without having to be thought about for it to beat. As a contrasting example, the act of typing this answer is a form of voluntary muscle movement, actively thinking about moving fingers to specific keys on a keyboard.

It mainly focuses on the lower back and hamstrings, though glutes and traps are pretty heavily involved. It also works on total body strength.

supinator

An isometric contraction builds tension but there is no joint movement.

endomysium

yes you can. your stomach area can improve its tone and definition if you constantly remember to flex throughout the day.

Rotator cuff tears that are full thickness can become too old to repair after about four months. This is due to curling and shrinking of the muscle. If the muscle shrinks too much or curls too much it can not be surgically reattached.

Muscle tissue is deep to epidermal tissue. Epidermal tissue is superficial to muscle tissue.

Actin is the thin filament and contains troposin and tropomyosin. Myosin is the thick filament and contains the myosin heads that will later hydrolyze ATP and essentially "walk" up and down the actin filament thus shortening the sarcomere. Once calcium binds to troposin, tropomyosin will be moved away from the active myosin actin binding site and ATP hydrolysis can begin.

The smooth muscle is striated and this allows for a smooth sliding across each other when muscles contract and extend

smooth muscle isn't striated, that's skeltal muscle.

but im trying to find the answer to the question aswell!

Fascia is a thin layer of tissue between organs. Fascia is called fascia.

there are 600 muscles in the human body and there are,206 bones in the body

Yes it does. The internal and external anal sphincters along with the puborectalis muscle allow the feces to be passed by pulling the anus up over the exiting feces in shortening and contracting actions.

the diaphragm is a muscle (very essential for breathing)

great sciatic nerve

churning is the process of shaking butter,cream,milk and various forms of butter churn have been used for the purpose.

Temporalis, Masseter and the Medial Pterygoid

False, NOT true.

The medial pterygoid muscle, the left medial pterygoid will deviate the jaw to the right and vice versa.
