Muscular System

In the human body there are aprroximatly 656-850 muscles. The figure is not exact because some authorities don't agree about which muscles slip off larger ones and which are separate muscles. Also, there can be a big difference in the variability from one person to another.

Also, in the human body there are 350 bones when you are first born but by the time your an adult some of your bones would have fused together to make only 206 bones.

it is called the diaphram.

Origin and Insertion

One of the points of attachment is the ORIGIN (typically the non-moving point of attachment). The other point of attachment is the INSERTION (typically the moving point of attachment).

For example - when the brachialis muscle (located on the upper arm) contracts - it shortens the distance between the origin (on the humerus - the upper arm bone and the insertion (on the radius - the forearm bone). The humerus does not move, but the radius does move - it moves closer to the humerus.

Yes they do, they're called antagonistic pairs. However, I have also heard that there is a paradox that happens when you try to stand up from a sitting position which should be impossible because your hamstings and quadriceps are both contracting at the same time rather than one contracting and the other relaxing as antagonistic pairs should work.

The nervous system which also interprets information from sensory units

biceps is voluntary because it only cotracts when it receive signal from the brain. Otherwise it can act reflex when some events stimulate it

the muscular system is connected to the skeletal and nervous system

Your muscle cells use the energy released in cellular respiration to synthesize new compounds to maintain its tissues; to transport material in and out of its cell; and to perform its mechanical function of expanding and contracting.

At a Blood Alcohol Concentration (BAC) of .05, your muscle function, memory and judgment decrease. Then at .1 BAC you lose control of emotions and feel physically sick.

The biceps attach to the radius bone (near your elbow) on a small bump called the radial tuberosity, and the the humerus(near your shoulder). Hope that helps!

The heart itself is a muscle that never gets tired. This is, in part, due to the inclusion of the cardiac muscle and the constant blood flow to the heart itself. Skeletal muscles tire after prolonged use and cardiac muscles maintain stamina for constant use.

If you don't workout here is your average - Bicep Curl - 8 - 10kg Bench Press 30 - 40kg This getting 10 reps of 20 out (10 in bench press) at 3 sets.. Although i suggest triangles oppose to bench press, works your stabilising muscles, ask your gym owner.

because it would be too much for your congitive brain to control. imagine every second for your body to work you have to think.. ok heart contract ... now rest...contract... and at the same time think lungs pull in air.... release... and consciously tell your body digest this food...

this is only a small margin of things you would have to think about if all your muscles were voluntary and you would have to do it every second you wish to live.

yes it is.....

The large dome-shaped muscle (not an organ) that separates the thoracic (chest) cavity from the abdominal cavity and aids in breathing is the diaphragm. Actually fibromuscular, the diaphragm is the main muscle that we use to inflate our lungs. It forms a partition between the two cavities, and creates a 'seal'. It allows the lungs to expand so we can take in and expel air. It is part of both the muscular and respiratory systems.

The antagonists would be those muscles that cause knee flexion. Hamstrings (biceps femoris, semimembranosus, semitendonosis) are the primary knee flexors, and would thus be antagonists to knee extension.

The biceps flexes the arm it does not extend it (straightens). The triceps brachii extends the arm. They do work together. If one is damaged and doesn't work as it should, the movement will be "jerky" and not smooth.

the heel, in particular the calcaneus. the joint utilised being the tibiotalar joint.

Action of the muscle

Shape of the muscle

Location of the muscle's origin and or insertion

Number of origins

Location of muscle relative to a bone or body region

Direction in which the muscle fibers run relative to some imaginary line

Relative size of the muscle

since bacteria have no organells surrounded by a membrane, making them prolaryotc cells. as the RNA of bacteria became better understood, scienrists realized that were two vastly of bacteria.these groups were so different that threr are are now kingdoms of bacteria.

LeukemiaThe cause of most human leukemia is unknown. It is a kind of cancer in which abnormal white blood cells multiply in an uncontrolled manner. they interfere with the production of normal white blood cells. Leukemia affects the production of red blood cells.

During the arm elevation phase from the 6 to 3 o'clock position, the supraspinatus muscle fired at its highest rate, centralizing the humeral head within the glenoid. From the 3 to 12 o'clock position phase, the posterior deltoid and teres minor muscles worked at their highest capacity to maintain arm elevation and externally rotate the humerus.
