What is the skeleton?

The person skeleton is quite merely a collection of around 206 various shaped bones that align with each various other to create a protective structure for the body that muscles can affix to and provide movement from.

An instance of the skeleton in the anatomical position deserve to be watched in the adjacent image.

 

What go the skeleton do?

The skeleton provides four significant functions, i beg your pardon are;

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

2. Protection: the protects our internal 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 provides a structure for muscle to attach. Then when the muscles contract they pull on the skeleton of the skeleton, i beg your pardon act like levers to produce movement. 

4. Supply & Storage: The skeleton that consist of the skeleton room a source of both red blood cells (which move oxygen) and white blood cell (which hit infection), i m sorry are developed within the bone marrow.

 

Why is the skeleton important?

When considering the four significant functions that the skeleton that is basic to check out why the is so important. There is no it us would simply be a pile of "jelly" lie on the floor, can not to move and also with no blood or immunity. So preserving a healthy and balanced functioning skeleton is component and parcel of being able to do all our daily tasks and get involved in all physical tasks effectively.

 

The bones system and also fitness

Understanding the skeleton system and its functions is an extremely important because that you as a an individual trainer. This is due to the fact that it can assist you finish everyday facets of your job such together assessing someone’s movement, identify dangerous movements and correcting exercise technique. 

For example when working as a personal trainer it’s the posture (position of the bones) the the skeleton that shows whether someone’s technique is exactly or if their movement patterns require refining. 

This have the right to be checked out in the listed below images of good and bad technique of a squat.

What is bone?

Bone is the rigid body organ that renders up the skeleton and also it has actually its very own nerves and also blood ship in bespeak to help sustain it.

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, solid and thickest in ~ the skeleton weakest point, typically the center of the shaft.

2. Cancellous bone; this has actually a honeycombed appearance and also is solid and hard without the weight of compact bone. The is uncovered mainly in the ends of bones.

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

Bones and the skeleton

As aforementioned the bones in ~ our body come in various shapes and align with each various other in stimulate to produce the skeleton. 

The significant bones the the person skeleton are displayed on the adhering to image v their common names and anatomical surname (in brackets). 

Knowing anatomical names absolutely helps when working with various other health experts (doctors, physiotherapists) however most clients evaluate you using typical names and terms that they understand. You obtain no ‘kudos’ for confusing your personal training client so certain you always talk v them in a language castle understand.

Axial skeleton: 

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

The main purpose of the axial skeleton is to provide protection because that the main nervous device (brain and spinal cord) and critical organs, such as the heart and lungs.

It is likewise the structure that provides the support and also attachment for your arms and also legs. This permits us to do daily movements such together walking, running, jumping and carrying.

 

Appendicular skeleton: 

The appendicular skeleton consists of the complying with six parts and also can be seen as the shaded area in the nearby diagram.

The main purpose of the appendicular skeleton is to allow movement to occur through the joints of our arms and legs. Without the appendicular skeleton we would be unable to relocate around and also do the activities we do on a daily basis.

 

Vertabral column

The vertebral column (spine) is a crucial part of the axial skeleton. The is important to have a good understanding the the spine together it is a typical area that civilization injure and have postural concerns with. 

For this reason, together a trainer understanding the spine and its natural curves will help you cue client when exercising in stimulate to save them safe, and also communicate v other professionals such as physiotherapists.

Key points of the vertebral column

The vertebral column is comprised of numerous individual vertebrae which are grouped together right into five different sections. These sections are detailed below and also can additionally be viewed on the surrounding diagram.

When analysing the spine or talk to one more professional, such together a physiotherapist, it help to reference each vertebra as a number. Therefore vertebrae are numbered in descending stimulate in their equivalent sections i.e. The top (superior) cervical vertebra is well-known as C1 and also the bottom (inferior) cervical vertebra is recognized as C7.
