Where is the sternocleidomastoid muscle located in the human body?
405383
The sternocleidomastoid muscle is located in the side of the neck, deep to the platysma and from mastoid process of the skull to the sternum.\n\nOne uper tendious head arises from superior nuchal line and second uper muscular head arises from mastoid process.\nOne end inserted in uper border of sternum and other end inserted in medial one third of the clavicle.

I'll try to answer this question without writing a thesis or dissertation.  Skeletal muscles have an origin, insertion, and tend to cross an axis point.  For example, the two muscle that make up the bicep originates from a point underneath the front deltoid.  They insert below the elbow and move the lower part of the arm inward to your body.  This is done through the brain sending a signal to the muscle to move.  These signals are neurons, which travel along the nerve pathways.  So the brain thinks bring the hand to the shoulder and the bicep moves your lower arm inward.  This is pretty much consistent with the other skeletal muscles in the body.  The brain sends signals that tell the muscle to contract or extend.  Well that is about as simple as I can put it.  I'm sure someone else can probably elaborate and give a better explanation.

Well, the cervical may be problematic... There are anterior and posterior.  In the anterior triangle of the neck, bounded by the sternal heard of the sternocleidomastoid laterally, midline medially, and clavicle inferiorly, you have the trachea, thyroid, larynx, common carotid artery, external carotid artery, internal jugular vein, anterior jugular vein, and hypoglossal nerve (cranial nerve XII) as major structures.  There are also lymph nodes and several smaller muscles.  \nThe posterior triangle is bounded by the posterior side of the sternocleidomastoid, the anterior side of the trapezius, and inferiorly by the clavicle.  It contains many nerve roots, the medial end of the brachial plexus, the third part of the subclavian artery, the suprascapular artery, the occipital artery, the external jugular vein, and occasionally the subclavian vein.\nThe femoral triangle is bounded by the inguinal ligament superiorly, the sartorius laterally, and the medial border of the adductor longus medially.  It contains the terminus of the femoral nerve, the branches of the femoral nerve, and the femoral artery and vein, along with a string of lymph nodes.

In human anatomy, the thymus is an organ located in the upper anterior portion of the chest cavity. The thymus plays an important role in the development of the immune system in early life, and its cells form a part of the body's normal immune system. It is most active before puberty, after which it shrinks in size and activity in most individuals and is replaced with fat.\n\nThe thymus is also present in many other animals. When animal thymus tissue is sold in a butcher shop or at a meat counter, thymus is known as sweetbread.\n\n\nFunction:\nThe function of the thymus in the immune system was determined by Jacques Miller. In the two thymic lobes, lymphocytes precursors mature into T cells (where T stands for “thymus”)[1]. The key function of the thymus is the selection of the T cell repertoire that the immune system uses to combat infections. This involves selection of T cells that are functional (positive selection), and elimination of T cells that are autoreactive (negative selection). Positively-selected cells will be taken care of by specialized Nurse Cells. In order to be positively-selected, pre-T cells will have to interact with several cell surface molecules, MHC/HLA, to ensure reactivity and specificity. Cells that pass both levels of selection are released into the bloodstream to perform vital immune functions. Negative selection is not 100% complete. Some autoreactive T cells escape thymic censorship, and are released into the circulation. Additional mechanisms of tolerance active in the peripheral exist to silence these cells such as anergy, deletion, cross-tolerance and regulatory T cells. If these mechanisms also fail, autoimmunity may arise.\n\nFurther info: \n\nhttp://en.wikipedia.org/wiki/Thymus

Objectives: to identify the heart as the largest muscle in the body, to describe the heart's role in pumping blood to the lungs and to all parts of the body \n\n \nProcedures:  \nStudent Information: Ask students to identify the strongest muscle of the body. Allow students to give their ideas and then explain that the correct answer is the heart. Show students diagram of the heart and share the background information with them.  \nThe heart works day and night to pump blood through the circulatory system. \nThe heart consists of two pumps. \nThe pump on the right side of the heart sends blood to the lungs where the blood obtains oxygen. \nThe blood which has obtained oxygen then travels back to the heart where it is pumped to all parts of the body. \n\nI hope this helps...

Sternum is the bone exactly in the middle of the rib cage where the ribs from either side meet.It requires to be opened with a bone saw during an open heart surgery.\nSupra sternal notch is the correct answer.Because supra means above or superior and it is above the sternum bone, so supra sternal notch. It is logical therefore, to expect infra sternal notch. Where would it be? See if you can feel it? Just below the sternum.

Muscles involved in a "zygomatic" (i.e., genuine) smile:\n\nZygomaticus major and minor. These muscles pull up the corners of the mouth. They're bilateral (one set on either side of the face). Total number of muscles: 4.\n\nOrbicularis oculi. One of these muscles encircles each eye and causes crinkling. Total: 2.\n\nLevator labii superioris. Pulls up corner of lip and nose. Bilateral. Total: 2.\n\nLevator anguli oris. Also helps elevate angle of mouth. Bilateral. Total: 2.\n\nRisorius. Pulls corner of mouth to the side. Bilateral. Total: 2. Grand total for smiling: 12.\n\nPrincipal muscles involved in a frown:\n\nOrbicularis oculi (again). Total: 2.\n\nPlatysma. Pulls down lips and wrinkles skin of lower face. Bilateral (though joined at midline). Total: 2.\n\nCorrugator supercilii (bilateral) and procerus (unilateral). Furrow brow. Total: 3.\n\nOrbicularis oris. Encircles mouth; purses lips. Unilateral. Total: 1.\n\nMentalis. Depresses lower lip. Unilateral. Total: 1.\n\nDepressor anguli oris. Pulls corner of mouth down. Bilateral. Total: 2. Grand total for frowning: 11.\n\nDespite the fact that smiling uses more muscles, Song believes it takes less effort than frowning--people tend to smile more frequently, so the relevant muscles are in better shape. You may feel this conclusion assumes a rosier view of the human condition than the facts warrant, but I defer to the doctor. Incidentally, a superficial, homecoming-queen smile requires little more than the two risorius muscles. So if your goal in expressing emotion is really to minimize effort, go for insincere.

The strongest human muscle\nDepending on what definition of "strongest" is used, many different muscles in the human body can be characterized as being the "strongest."\n\nIn ordinary parlance, muscular "strength" usually refers to the ability to exert a force on an external object—for example, lifting a weight. By this definition, the masseter or jaw muscle is the strongest. \n\nThe 1992 Guinness Book of Records records the achievement of a bite strength of 975 lbf (4337 N) for two seconds. What distinguishes the masseter is not anything special about the muscle itself, but its advantage in working against a much shorter lever arm than other muscles.\n\nIf "strength" refers to the force exerted by the muscle itself, e.g., on the place where it inserts into a bone, then the strongest muscles are those with the largest cross-sectional area at their belly. This is because the tension exerted by an individual skeletal (striated) muscle fiber does not vary much, either from muscle to muscle, or with length. Each fiber can exert a force on the order of 0.3 micronewtons. By this definition, the strongest muscle of the body is usually said to be the Quadriceps femoris or the Gluteus maximus.\n\nAgain taking strength to mean only "force" (in the physicist's sense, and as contrasted with "energy" or "power"), then a shorter muscle will be stronger "pound for pound" (i.e., by weight) than a longer muscle. The uterus may be the strongest muscle by weight in the human body. At the time when an infant is delivered, the human uterus weighs about 40 oz (1.1 kg). During childbirth, the uterus exerts 25 to 100 lbf (100 to 400 N) of downward force with each contraction.\n\nThe external muscles of the eye are conspicuously large and strong in relation to the small size and weight of the eyeball. It is frequently said that they are "the strongest muscles for the job they have to do" and are sometimes claimed to be "100 times stronger than they need to be." Eye movements, however, probably do "need" to be exceptionally fast.\n\nThe unexplained statement that "the tongue is the strongest muscle in the body" appears frequently in lists of surprising facts, but it is difficult to find any definition of "strength" that would make this statement true. Note that the tongue consists of sixteen muscles, not one. The tongue may possibly be the strongest muscle at birth.\n\nThe heart has a claim to being the muscle that performs the largest quantity of physical work in the course of a lifetime. Estimates of the power output of the human heart range from 1 to 5 watts. This is much less than the maximum power output of other muscles; for example, the quadriceps can produce over 100 watts, but only for a few minutes. The heart does its work continuously over an entire lifetime without pause, and thus can "outwork" other muscles. An output of one watt continuously for seventy years yields a total work output of 2 to 3 ×109 joules.\n\nThere is no such thing as dense muscles, although some claim there are.

When a muscle goes into contracture, it is attached to a bone.. that bone will move according to the amount of tension applied to it.. When the vertebrae are involved, you also have to include nerve impingement. Which sets up an inflammatory process of the nerve and the surrounding tissues. If you press at the base of the skull you may find it creates or increases the pain factor. \n\nThis is a routine condition presenting to a doctor of Chiropractic..Would recommend you consider seeing one and soon.
