Muscular System

Intercostal musles are present between the ribs.

well there are many muscles in the human body not just 2.

plz read your science book.

Smiling is a facial expression, so the skeletal muscles of the face would be used. In particular the zygomaticus. or the ****** it makes me smile

Bones and muscles work together to form levers, which increase the machanical advantage of most movments. When a muscle that connects two bones gets shorter, the bones are pulled closer to each other. For example, tendons attach the biceps muscle to a bone in your shoulder and to a bone in your forearm. When the bicep shortens your forearm bends toward your shoulder.

Voluntary muscles are muscles that are controlled by the person's will. The difference between the voluntary muscles and involuntary muscles are you don't have to think about involuntary muscles such as your heart. An example of voluntary muscles are your arms, legs, mouth, and fingers.

skeletal muscle

Myolysis is the medical term meaning breakdown or degeneration of muscle tissue. When you lots of cardio sessions. It occurs when the muscle don't have fuel , and the fat storage it's could be used , but the proteins are easyer to breakdown...

The deltoid muscle is one muscle with three sections. Each one is located in your left and right shoulder. All three of them together perform an action called abduction to the shoulder (glenohumeral joint.)
in the upper arm
It is located at the shoulder.

A concentric movement would be flexing the elbow and curling a dumbbell towards the shoulder, an eccentric contraction would be the opposite movement ie bringing the dumbbell back down towards the thigh.

Muscle fibers converge into tendinous material that attaches a portion or body of the muscle to specific bony landmarks on the skeleton. The place that muscle fibers become tendon can be called, for lack of a better term, a musculotendinous junction.

Tendons attach muscles to bones (just as ligaments attach bone to bone) at landmarks on the skeleton. Most of these landmarks have names of their own, based on things like shape, location and/or size. Depending upon the depth to which one wants to focus on these attention points, they can be further divided into origin and insertion points, meaning that a muscle originates and ends at specific, mappable points on the skeleton and those points are, for the most part, the same for each person.

Your heart

I believe that's called a cramp, and its very unpleasant. See that is why you need to stretch; when you stretch its not just your muscles, but the veins and nerves within the muscles being stretched, and because I think 70% of your body weight, its somewhere along those lines, is skeletal muscle tissue (assuming you're not obese), it is important to keep the muscles healthy. The muscles need constant blood flow, and veins need to be kept pliable. If you don't strength train your muscles atrophy and stiffen, and your heart has to work harder to get blood to various parts, and if you don't stretch, the veins become less and less flexible and its harder for the heart to get blood to the muscles in the first place. Additionally, believe it or not the nerves too are fluid dependent; human bioelectricity is rooted in a chemical reaction which, I believe involves water and sodium. Anti depressants are sodium based, to allow the electrical transmission between nerves to work better. Human nerve cells, if I'm not mistaken, are basically long sacks of saltwater, which constantly channel electricity; because like veins they are fluid based, if nerves loose flexibility, and more crucially, if less and less blood goes to them, they function less and less effectively and once you loose nerve function all other things begin falling apart. You have no idea, how much of your body is sheer nerve function; part of the reason many mentally ill people that never receive treatment are deformed, is because what happens in your brain, sooner or later, happens in your body.

If you are a very sad person for example, the neural deterioration in the brain, inevitably transfers to central and peripheral nerve deterioration Sigmund Freud, the world's most famous Psychologist, was concerned with mental health because he correctly observed that the reason many of his patients kept coming back, was because they were mentally ill. He gave them medicine, prescribed rest and all that he did his job as a doctor alright? However, his patients, were not getting better; it was not until he started listening to their problems, analyzing the mind in an abstract manner, and giving them advice on how to solve them that their health problems FINALLY stopped. There is a "mind body" connection, and believe it or not the most important fitness activity is stretching.

There are many muscles in the eye that control it. The four major muscles are the superior and inferior rectus (control up and down movement) and the lateral and medial rectus (control outer and inner movement). There are also two minor muscles, namely the inferior oblique (controls motion up and out or "extorsion") and superior oblique (controls motion down and in or "intorsion").

In additional to muscle which control movement, the lens of the eye is attached to a muscle called the ciliary body which controls anatomic movements and shape/focusing power of the lens. As we get older, this process of focusing, or accommodation gets weaker and most adults over 40 require reading glasses (magnifiers).

Finally, the iris or colored part of the eye is a muscle which can contract and expand and control the amount of light which enters the eye in various illuminated environments.

Smooth muscles produce a slow movement of the stomach mixing the contents. This muscle is not voluntary as you do not have to think about it as you do with your legs and arm muscles.

each of these organs is made of tissues composed of different kind of specialized cells

There are four muscles used for horizontal adduction of the shoulder. These muscles are the pectorals major, middle deltoid, latissimus dorsi, and coracobrachilis.

The parasympathetic nervous system is the portion of the nervous system that is in charge for controlling internal organs and also the glands that acts involuntarily. The parasympathetic nervous system has also the ability to give orders to a body like times of danger, to digest, to release waste and urine from our body and also lacrimation.

cardiac muscle and smooth muscle of arteries and of course the skeletal muscles surrounding the veins (in lower limb for example).

the muscle spindle detects it, and causes reflexes that automatically make slight alterations to muscle tentions, so that you stand up right.

the belly of the muscle is where the motor point is located cat for days gift doe apple fart poop head deck and the movement occurs. usually located in the middle of the muscle/ bulkiest part of the muscle poop tart
