What is the skeleton?

The human skeleton is quite merely a repertoire of around 206 different shaped bones the align with each other to develop a protective structure for the body the muscles can connect to and administer movement from.

What go the skeleton do?

The skeleton offers four major functions, i m sorry are;

1. Support : It offers a framework to support the organs and tissues the the body.

2. Protection: that protects our inner organs. The skull protects the brain; the thorax (sternum, ribs and also spine) protects the heart, lungs and also other viscera (organs in ~ the thorax).

3. Movement: It gives a structure for muscles to attach. Then as soon as the muscle contract they traction on the bones of the skeleton, i beg your pardon act choose levers to create movement. 

4. It is provided & Storage: The skeletal that make up the skeleton room a source of both red blood cells (which transfer oxygen) and also white blood cell (which struggle infection), i m sorry are created within the bone marrow.

 

Why is the skeleton important?

When considering the four significant functions that the skeleton the is easy to view why that is so important. Without it us would merely be a heap of "jelly" lie on the floor, can not to move and with no blood or immunity. So keeping a healthy functioning skeleton is component and thoreau of being able to carry out all our daily tasks and participate in every physical activities effectively.

 

The skeleton system and fitness

Understanding the skeleton system and its functions is an extremely important because that you as a an individual trainer. This is because it can help you finish everyday elements of your task such as assessing someone’s movement, identify dangerous movements and correcting practice technique. 

For example when functioning as a personal trainer that the posture (position that the bones) that the skeleton that indicates whether someone’s method is correct or if their activity patterns need refining.

What is bone?

*
Bone is the rigid organ that renders up the skeleton and it has its very own nerves and also blood vessels in order to aid sustain it. Bones additionally have a clever construction that enables them to stay lightweight however strong. This is due to the fact that they are developed out the multiple class of three different varieties of tissue, these are;

1. Compact bone; this is heavy, dense, strong and thickest at the skeleton weakest point, usually the center of the shaft.

2. Cancellous bone; this has actually a honeycombed appearance and is strong and tough without the weight of compact bone. The is discovered mainly in the ends of bones.

3. Periosteum; this is the membrane of connective tissue that currently the outer surface of every bones. It houses the nerves and also blood vessels the innervate and also nourish the underlying bone and acts together an attachment because that tendons and ligaments.

Bones and the skeleton

As abovementioned the bones in ~ our bodies come in miscellaneous shapes and also align v each other in bespeak to develop the skeleton. 

The major bones of the person skeleton are shown on the complying with image through their typical names and anatomical name (in brackets). 

Knowing anatomical names definitely helps when working with various other health professionals (doctors, physiotherapists) yet most clients appreciate you using common names and also terms the they understand. You obtain no ‘kudos’ for confusing your personal training clients so ensure you always talk v them in a language they understand.

Although we often look at the skeleton as a totality structure, it can likewise be separated into 2 groups, the axial and also appendicular skeleton.

 

Axial skeleton: 

The axial skeleton consists of the following three parts and can be viewed as the non-shaded area in the adhering to diagram.

The key purpose the the axial skeleton is to carry out protection because that the main nervous device (brain and spinal cord) and vital organs, such as the heart and also lungs.

It is additionally the framework that gives the support and also attachment for your arms and also legs. This enables us come do day-to-day movements such together walking, running, jumping and also carrying.

 

Appendicular skeleton: 

The appendicular skeleton is composed of the following six parts and can be viewed as the shaded area in the nearby diagram.

The main purpose the the appendicular skeleton is to permit movement to take place through the joints of our arms and legs. There is no the appendicular skeleton we would be unable to move around and do the activities we carry out on a everyday basis.

 

Vertabral column

The vertebral column (spine) is a crucial part that the axial skeleton. That is necessary to have a an excellent understanding the the spine as it is a usual area that people injure and also have postural issues with. 

For this reason, as a trainer knowledge the spine and its natural curves will help you cue client when exercising in stimulate to keep them safe, as well as communicate v other experts such as physiotherapists.

Key point out of the vertebral column

The vertebral column is consisted of of several individual vertebrae which space grouped together into five different sections. This sections are noted below and also can likewise be viewed on the adjacent diagram.

cervical - seven vertebraethoracic - twelve vertebraelumbar - 5 vertebraesacrum - five vertebraecoccyx - 4 vertebrae

 

When analysing the spine or talking to one more professional, such as a physiotherapist, it help to reference each vertebra as a number. Therefore vertebrae room numbered in descending bespeak in their matching sections i.e. The top (superior) cervical vertebra is known as C1 and also the bottom (inferior) cervical vertebra is known as C7.
