The nerve system that is the nose are the ophthalmic (V1) and the maxillary (V2) divisions of the trigeminal nerve.

The noses ophthalmic division has 3 main branches which are the nasociliary, frontal and the lacrimal.

The nose works as an organ for smelling by taking the molecules in from the air and then those molecules stimulate the olfactory sensory neurons that are high inside the nose.

Inside the nose there are a few million of the olfactory sensory neuron cells.

When we smell an odor or smell something we actually breathe in tiny molecules which is what we smell.

The nose is so important as the nose helps you smell, taste and also breathe.

Your nose also allows the air around you to enter your body and helps filter any debris from the air and warms the air and moistens it before it enters your body.

You inherit your nose from your mom and dad although if you're a boy then you are more likely to inherit your nose from your mom and if you're a girl then you're more likely to inherit your nose from your dad.

Noses do change with age and can change shape and size as you get older.

Noses do get slightly bigger with age and the nose can also change shape with age.

The human nose is almost fully grown by the time you reach your teens although the nose can still change shape and grow some as we age and get older.

The human ears also are 90 percent grown by the age of 6 years old but they can also grow some and change shape the older you get.

The part of the human body that does not grow from birth to death is the innermost ear ossicle and the eyeballs.

As you grow or develop the ossicle does not grow in size nor does the eyeballs.

Your legs are stronger than your arms as your legs hold up the weight of your body so they need to be much stronger than your arms.

The legs are also able to push as much as 4 times more weight than your arms can.

Legs also have a much better advantage than arms when it comes to endurance.

The strongest bone in your body is your femur which is one of the most well described bones in the human skeleton in the fields ranging from forensic medicine and clinical anatomy.

The femur is the bone of the thigh or upper hind limb, articulating at the hip and the knee.

The part of human body that does not burn in fire is the bones.

The bones will burn however but it takes a temperature of 1,292 degrees F or above and even then the bones don't turn completely to ash.

The body part that stops growing first are the hands and feet.

After the hands and arms the arms and legs then also stop growing.

As you progress through puberty your growth plates mature and then at the end of puberty the growth plates fuse and stop growing.

A good way to know if you will still grow and have growth potential is through an X Ray of your wrist.

The X Ray of your wrist is called a pediatric bone age  and it shows if your growth places are still open or not.

If your growth plates are still open then you will likely still grow but if your growth plates are closed then you stop growing.

Your body knows to stop growing when the bones fuse together.

The high concentration of estrogen in human blood is what causes the growth plates of our bones to fuse.

This fusion effectively closes the growth centers of long bones and renders them unable to respond to the hormones that initiate growth.

Humans take so long to grow as the brain which is hungry for energy diverts energy from our bodies which slows down growth and leads to a long childhood and adolescence.

Humans are considered late bloomers and late growers when compared with the other primates.

Growth hormones are made in the pituitary gland, which is the most important factor for growth and growing fast.

Things that makes us grow fast are proper nutrition, plenty of sleep, exercise, water and growth hormones.

The 4 things that humans need to grow are food, water, air and exercise.

As humans we also need growth in every capacity: spiritually, intellectually, physically, and emotionally.

Development in all four areas is key to a healthy life.

The age that your body grows the most is between the ages of 12 to 15 years of age.

Growth spurts for boys is around 2 years later than the growth spurt of girls and by age 16 most boys have stopped growing although the boys muscles will continue to develop.

The fastest body part to grow is the skin.

As your body grows your skin also grows and stretches to fit your growing body.

The fattiest organ in the body is the human brain which is made of fat and not only does the fat make the brain the fattiest organ the fatty acids are also very crucial for your brains performance.

The organ that humans do not need is the Appendix.

Humans can easily live without an Appendix and a lot of people have the Appendix removed before it bursts and live just fine without it.

Other organs and body parts that you can live without are wisdom teeth, teeth, Coccyx, External Ear, Male Nipples, Arrector Pili, Plica Semilunaris.

The only body part that cannot repair itself is the teeth.

While new teeth can grow once baby teeth fall out the adult teeth cannot regrow or repair themselves once damaged and need dental work to repair and treat.

The only body part that grows back is the skin which can regenerate although the liver is also an organ and body part that can also grow back.

Other parts of the body that can grow back are fat, brain tissue, fingernails, toenails,

Regeneration means the regrowth of a damaged or missing organ part from the remaining tissue.

As adults, humans can regenerate some organs, such as the liver.

If part of the liver is lost by disease or injury, the liver grows back to its original size, though not its original shape.

Although some people who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant.

Researchers from Michigan State University believe blood clotting factor fibrinogen may be responsible.

While some brain tissue can sometimes regenerate the brain actually can't regenerate itself well because when the brain is damaged its cells find it harder to make new ones.

This is because the brain has very few of the special cells, or stem cells.

Humans can't regenerate body parts other than skin and tissue or nails because mammals have more complex biological structures; limb regeneration would require sophisticated controls to ensure that limbs and organs don't grow out of control.

Humans, for example, are already equipped with safety mechanisms to ensure that individual cells don't grow uncontrollably.
