How many degrees of freedom to the human body?
That can be a difficult question to answer. Since mechanically all objects can have at most 6 degrees of freedom, the next question would be how many parts of the human body move. Nearly all parts in the human body can move, and if cells were counted in the answer would be astronomical. However some deduction can be used to reduce that number to a more manageable size. For instance if humans could control the individual cells, then the movements capable of being performed would be limitless and therefor not contained by the skeletal frame of the body. (Think about the shape shifters from Star Trek). Now that cells are out of the question, we are left with muscles and bones. Again this number can be reduced by analyzing the movement types. A person can generate movement from a muscle, however it is governed by the joints nearest that muscle. Therefore the muscles themselves don't have the afore mentioned six degrees of freedom, and can be looked at as mere extensions of the degrees of freedom of the nearest joint or joints. So what does this mean exactly? It means that all movements of the human body are coordinated movements of the joints, and all movements can start independently from any one joint. The human body contains 230 movable or slightly movable joints, and if there are six degrees of freedom for each of them it gives a total of 1380 DOF

To answer this question, we have to ask ourselves the question,what is an organ? An organ is a complex structure made up of 2 ormore different tissue types. Examples of organs include the skin,each muscle, each bone, a lymph node, a blood vessel, a nerve, thesense organs, etc. Given that there are o…ver 700 muscles in thebody and that there are on average 206 bones, there would be wellover 1 organ in the body if you include all of the internal organs.

There is no universally agreed definition of what a skeletalmuscle is, so there are differences of opinion as to where onemuscle ends and another begins, hence the variation in numbers.There are also several small skeletal muscles in the human bodythat may or may not be present in certain individual…s due togenetic factors. For example the palmaris longus muscle is notpresent in approximately 14% of the population, and the peroneusquartus is a muscle rarely found in the human body. There is also another kind of muscle called smooth muscle, whichcannot be consciously controlled. It's near impossible to say howmany smooth muscles there are in the body since they can vary insize greatly and are not exactly easy to count. . There are three types of muscles smooth, skeletal, and cardiac. Thecardiac and smooth are involuntary meaning you do not have to thinkabout them to work. Skeletal which as you can guess move yourskeleton are voluntary meaning you have to think about moving thembefore they move. . Humans have between 650 and 850 muscles in their body. The rangeof numbers is due to debate over muscle classification. Someexperts count 650 due to grouping related small muscles with thesame origins. Other experts believe the number is as high as 850because each individual movement the muscles create. 206 ( Full Answer )

There is no set number of valves in your body. The most obvious number might be FOUR because most people are aware of the four valves in the heart which maintain the correct direction of blood flow from atria to ventricles and then from ventricles to arteries. The reason there is no single answe…r to the question is because large veins contain one-way valves that help to return blood to the heart. In addition, the lymph vessels also contain one-way valves that help to move lymph. So there is no correct answer. Maybe some medical anatomist can tell us the exact number but I am not sure that anyone knows how many valves are in the veins and lymph vessels. ( Full Answer )

Not counting individual cells or small blood and lymph vessels, there are about a dozen major organ systems. These contain hundreds of individual structures whose functions are integrated by the nervous system. Some major body systems and their organs : Circulatory system: heart, aortic chamber…, arteries, and veins Digestive System: teeth, tongue, salivary glands, esophagus, stomach, liver, gallbladder, pancreas, intestines, rectum, and anus. Endocrine system: hypothalamus, pituitary gland, pineal gland, thyroid, parathyroids, and adrenal glands External (integumentary) structures: skin, hair and nails External sensory structures : eyes, ears, nose, lips Internal sensory structure : optic nerves, cochlea Immune system: tonsils, adenoids, thymus gland, and spleen. Lymphatic system: lymph nodes and vessels Muscular system: muscles,ligaments,and tendons - typically 320 separate muscle pairs, 640 total Skeletal system : bones and cartilage (206 bones in a human adult) Nervous system: brain, spinal cord, and nerves Reproductive system (sex organs) Female - ovaries, fallopian tubes, uterus, vagina, mammary glands. Male - testes, vas deferens, seminal vesicles, prostate gland, and penis Respiratory system: pharynx, larynx, trachea, lungs and bronchi, and the diaphragm Urinary system: kidneys, ureters, bladder and urethra Vestibular system : inner ear organs, including semicircular canals, utricles, and saccules There are over 7500 named parts of the human body.

There is no definitive answer to this question. The first problem is that the number of bones in a body changes. A fetus has about 300 bones, but by the time of birth, many of them have fused together. The average adult human has 206 bones. Also, what constitutes a "joint" is problematic. The sku…ll is made up of a number of bony plates that knit together along their edges into a permanently fused structure that we think of as a single unit. Do we count each of those plates and where they meet each distinct other plate as a "joint"? Consequently, there is no simple or reliable answer to this question. The number is certainly in the range of the mid-200s to the mid-300s. ( Full Answer )

There are many many millions of single cell neurons. It is estimated that there are up to 100 billion neurons in the human brain. It is likely that there are more neurons in the human body than any other cell type. many neurons are in the brain others are in tracts or organised pathways within the b…rain and spinal cord. Outside this central nervous system there are the larger most common obvious collections of individual cells that all follow the same or similar anatomic route through the body (within a single outer connective tissue pipe or sheath); for example the sciatic nerve and the radial nerve. These are the 'nerves' named and accepted by the medical community. There are three main types of nerves and, according to Wikipedia, 214 named nerves. However a biologist will soon point out there are many unnamed nerves, such as those that run to small sensors in the skin or the periosteum, and many that are repeated many more times than twice (the intercostal nerve for example). There is also a high level of personal differences in the actual neuronal anatomy of the content of named nerves so one persons sciatic nerve will not have exactly the same number neurons as the next. Neurons that commonly exit at one particular level in the spine may also in some persons exit at a higher or lower level in others. So the answer in fact must be that there are many thousands, but quite possibly millions, of bundles of smaller unnamed groups of neurons that are clearly small nerves, but medically there are the predictable larger nerves - 214 of them. It is said that there are enough neurons in the human body that if all the other cells were somehow removed the network of fine smaller nerves and neurons would be numerous enough to enable you to easily recognize the individual concerned and to recognize every tissue layer in his or her body. Finally it should also be pointed out that nerves do not supply cells or parts of the body - neurons do. Nerves are basic anatomical pathways acting as conduits within which are the real active components of information transmission - the neurons. There is perhaps just one nerve to any given muscle but this will contain perhaps a thousand neurons. each neuron branching at its end to supply thousands of muscle cells with their individual signals.

"The human hand has 27 degrees of freedom: 4 in each finger, 3 for extension and flexion and one for abduction and adduction; the thumb is more complicated and has 5 DOF, leaving 6 DOF for the rotation and translation of the wrist." (from ElKoura and Singh 2003 'Handrix: Animating the Human… Hand' Eurographics/SIGGRAPH Symposium on Computer Animation). They cite Grant's Atlas of Anatomy. However, robotics engineers tend to work with reduced DoF models, in particular cutting down on the allowable movements of the fingers and thumb. Edit: . In fact the human hand has 22 degrees of freedom. I don't see how the wrist has 3 translational degrees as suggested in the previous answer. We would have translational degrees if our limbs could extend/contract in a telescopic manner. . All fingers except the thumb has 3 flexion/extension and 1 abduction/adduction. The thumb is missing one joint therefore that makes a total of 4*4 + 3 = 19 excluding the wrist. The wrist has 3 rotational degrees of freedom, hence 22 DoF in total. . ( Full Answer )
all together you should have 10 on 1 hand you should have 5 you get it? 5+5=10 like this: 5,6,7,8,9,10 (or you can count on your fingers to do maths- most people do) NO. we do not have 5 fingers in our one hand or 10 total in both either! we have two thumbs,right? so,human body has total 8 finge…rs in two hands with two thumbs.. Also,as the foot in called toe,counting those 10 digits in makes total 18 fingers,coz it ius called Big toe or large toe/small toe etc... plz chek wikipedia to confirm this.

Femur is the thigh bone you have one in each leg, the answer is therfore two.
it is controversial due to total body cells and the "actual" ratio of cells per capillary bed. so 4 billion up to 800 billion is the right answer
There are 46 chromosomes in each human body. You get half of your chromosomes (23) from each parent. When you combine 23 and 23 , you get 46.
There is no way to answer that question because our bodies are covered with billions as well as the billions inside our digestive tract. There are more germs associated with a person than there are persons on this planet.
