Muscular system

Modern orthodontics take into account of balance between dentofacial complex as a whole and the position of hyoid bone in different Angle’s class malocclusion has intrigued and attracted many researchers. The hyoid bone is unique in that it has no bony articulation with any other bone but is instead suspended in the soft tissue via ligaments and muscles (Romanes et al 1983). Different muscles such as infra and suprahyoid muscles and genioglossus muscle influence the position of the hyoid bone…

Of course, just as it’s largely variable among people as to just how much of each, it’s also largely variable among individual muscles. Simply put, different people have different muscular composition, and that should go without saying. What’s worth focusing on, however, is the role each of our muscles plays in basic human function. Though research is limited on the topic, it’s safe to assume a generally greater allotment of endurance-geared…

while the elbow crease is clearly marked. Mycerinus hands are tightly clenched against his body, while his bottom stance shows power. His left foot is clearly in front of his right, similar to the queen. The visible sections of the legs are clearly muscular: the shins and the knees are unrealistically protruding from the body, which emphasizes athleticism and muscularity in the legs. The abdomen follows a similar pattern: Mycerinus’ torso is extremely rigid and strapping. The pectoris muscle is…

Of the three types of muscle cells, skeletal muscle cells are the most recognizable as muscles because skeletal muscles are the type used in voluntary movement. Skeletal muscles cells are some of the most distinct differentiated cells in the human body, this distinction is likely because of the clear and specific purpose in the body of being the source of contractions that allow voluntary movement. I chose skeletal muscle cells because it’s fascinating to me how movement of the body is such a…

The Basso, Beattie, and Bresnahan (BBB) locomotor scale The Basso, Beattie, and Bresnahan (BBB) scale (numbering 0–21) is a point scale used in the analyzation of the activity of the limb joints of animals. Its locomotion rate is based on various aspects of the hind limb function like the weight support and toe clearance, just to mention a few [37]. All results were obtained at time points of 2 weeks to 8 weeks post-operation along with the blinded examination that was executed by two scorers.…

How big are your spiritual muscles? Every body builder knows there are just three primary exercises to gain size and strength. Squat, dead lift and bench press. Do these three consistently and you'll gain size and strength. Building a relationship with God is much the same. There are really just three major components to building a relationship with God: Prayer, Bible study and Church. #1- Prayer... Prayer is communication with God. Every relationship is built on communication. When…

Importance of Testosterone The body of men comprises of stronger muscle mass and bones. This is because the level of Testosterone is properly sustained which is responsible for the absorption of many nutrients into muscles. For those who don’t know about it, Testosterone is an androgenic hormone produced in male’s body which is also a key precursor of masculine traits. The hormone defines male’s characteristic and also serve various functions inside the body. Testosterone optimal secretion…

Muscles and connective tissues shorten over time and that results in less flexibility. If your muscles have gone some time without being used, they tend to become weaker and quite stiff. The risk of injury is greatly increased when you start to use those muscles suddenly. If you are doing regular stretching exercises to lengthen and strengthen your muscles, injury can be easily avoided. A pulling sensation is normal while you're doing stretching exercises. It can be mildly uncomfortable but if…

During this experiment I will be looking at how pressure and force cause tension and compression on your toes (Pointe Shoe Physics, Concussion) . When you go on pointe you compress your toes into this shoe which you only stand on your toes. This causes all your weight to be all your toes. (Danielle Spector, The Pressure Pointe) My purpose is to determine how much pressure is put on toes while on pointe in different positions. Weight is the amount of force you put on something or someone. When…

To begin, the role of the ACH receptor is vital to biology. An incoming action potential to an alpha motor neuron causes acetylcholine or ACH, at the end plate. The ACH binds to ACH receptors on the sarcolemma causing a depolarization through sodium influx. In your body, calcium performs a number of basic functions. The body uses around 99 percent of its calcium to keep bones and teeth strong, as a result, supports skeletal structure and function. The rest of the calcium in your body plays…
