You are describing a symptom of TMD (TemporoMandibular joint Disorder). It sounds like you may be displacing the disc that acts as a cushion between the bones that make up the joint.

What are the antagonists of the shoulder girdle at Upward rotation?
The Trapezius muscles are involved in upward rotation of the scapula. However Trapezius is agonist/antagonist to itself as the upper portion elevates the scapula, the middle portion adducts the scapula and the lower portion depresses the scapula, while all parts are involved in upward rotation of the scapula.
The Serratus Anterior assists in rotating the scapula (glenoid fossa) upward, (which would make it a synergist with the trapezius). The Serratus Anterior is antagonist to the upper and middle portions of Trapezius, so we are back to the agonist /antagonist relationship of the traps.
That's about all I can contribute to this question.
physical strength is the state or property even quality of being strong. It is the power to resist attack. the power to ressist strain or stress. The ability to maintain a moral or intellectual position firmly. Capacity or potential for effective action. Effective or binding force. synonyms: strength, power, might, energy, force.
How can you help prevent muscle injury?
You can prevent muscular injury as a result of exercise by warming-up and cooling-down before and after any moderate to high intensity exercise. How long a warm-up should take varies depending on the activity the individual is preparing for. Stretching as part of a warm-up, while considered by some to have mixed benefits and risks, is generally accepted to be beneficial. However, some stretching, e.g., ballistic stretching, is believed to do more harm than good, and should therefore be avoided.
Here is a list of some of the benefits that may come from warming-up before exercise:
- Warming-up results in the increased production of synovial-fluid, which minimises the friction between joints.
- It causes the capillaries in your body to dilate, which means that a greater volume of blood is able to reach your muscles.
- It promotes the breakdown of glycogen into glucose, which is used for energy in metabolic reactions.
- strong flexibility (apex)
Can over-training cause Muscle atrophy?
From what I've studied, yes it can, but only in extreme cases. Scientifically speaking, when you go to te gym you are ripping your muscles and breaking them down. So overtraining could cause atrophy. You are more likely to feel other symptoms before atrophy. Also If you are working out fairly consistently and doing cardio, you could be losing body fat so your arms aren't losing muscle, they are losing fat stores. However if you are worried about losing muscle mass, eat more protein, carbs and calories. As for atrophy, it can happen So be vigilant and train smart. Hope this helps :)
Does cycling make your calf muscle too big?
Answer
No one but you can say what "too big" means for you.
Me I don't think so. Unless all riding you do is loads of short, all out sprints and high-intensity climbs, bicycling is generally a lot more about endurance than outright sprints. And endurance athletes rarely get very big.
Do a net search for pro cyclists and marathon runners and see if you can find anyone looking bulky in there.
Answer
oh my gosh yes! after a month of cycling i saw that my calves got bigger but if you don't want to have big calves do something else besides cycling like swimming it's a full body workout and you don't get all sweaty.
because it is pumping against more resistance. it has to be stronger to get blood to the entire body. the RIGHT ventricle only has to pump blood to the lungs.
What is the clinical importance of cremestric muscle reflex?
Well you can asses the function of ilioingunial nerve and genitofemoral nerve.
Cremasteric relfex can be demonstarted by lightly touching the skin of the upper medial thigh, resulting in a slight elevation of the testis.
The sensory fibers of the reflex are carried by the L1 fibers of the Ilioinguinal nerve and the motor response is a functional of the genital branch of the genitofemoral nerve that innervates the cremastric muscle.
What is the difference between smooth and skeletal muscle?
Skeletal muscle is striated (when looked at under the microscope, striations or stripes can be seen). It forms the muscles which help to move bones and joints and is voluntary, or under our conscious control. It is stimulated by impulses from the brain or spinal cord.
Smooth muscle (or visceral muscle) is involuntary, meaning that it is not under our conscious control. It is stimulated to contract by nerve impulses, hormones and metabolites. Smooth muscle is found in the walls of hollow organs such as blood vessels, parts of the respiratory tract, in the urinary bladder and the uterus. It helps to regulate the diameter of blood vessels and respiratory tracts, it propels food along the digestive tracts, and it expels contents of the bladder and the uterus. Structurally, it is non-striated.
