Lesson 9: Axial Skeleton Insights

Overview

The axial skeleton forms the central axis of the body. It provides structural support, protects vital organs, and serves as the attachment point for many muscles. A strong understanding of this system is essential for personal trainers to design safe and effective exercise programs.


---

Main Components

1. Skull – Protects the brain, supports facial structure, and provides attachment for chewing and neck muscles.


2. Vertebral Column (Spine) – Composed of 33 vertebrae (7 cervical, 12 thoracic, 5 lumbar, 5 sacral fused, 4 coccygeal fused). It supports body weight and protects the spinal cord.


3. Thoracic Cage (Ribs & Sternum) – Protects the heart and lungs, assists in breathing, and supports upper body strength.




---

Key Functions

Protection: Shields the brain, spinal cord, heart, and lungs.

Support & Posture: Maintains upright position and balances body weight.

Movement: Provides leverage for muscles during bending, twisting, and breathing.

Attachment Points: For muscles of the head, neck, back, and thorax.



---

Training Insights

Maintaining spinal health is vital for athletes and clients.

Core training supports the axial skeleton by stabilizing the spine.

Poor posture can lead to spinal misalignments and injuries.

Breathing exercises improve thoracic mobility and rib cage function.

Proper lifting techniques prevent stress on vertebral discs.



---

Practical Tips for Trainers

1. Teach neutral spine alignment during exercises.


2. Strengthen core and back muscles to support the spine.


3. Avoid excessive spinal loading in beginners.


4. Use mobility drills for thoracic extension and rotation.


5. Educate clients on posture in daily activity

00:00Hello everyone, welcome to our YouTube channel. This is Jeff Singh.
00:07In today's video, we will learn lesson number 9, which is Skeleton Anatomy.
00:13Skeleton Anatomy is 15 years ago. Skeleton is what is our head of our head,
00:20which we speak in Hindi. Skeleton is a system that is our whole body,
00:27is our whole structure of content, what is our chain itself?
00:34This is a whole framework which are complete with bone,
00:36and is complete with heart and heart of heart.
00:40We have total 12 systems as well as a nervous system, digestive system, immune system.
00:47That's the right, the skeleton is a whole system.
00:50This is a whole framework and supports.
00:56so that we can stand up and stand up right position
01:00and think about that, if you don't have one body
01:04one body doesn't really look at it, what's your body
01:08if you don't have one body or one body
01:12we can do it like this, if we don't have a body
01:16we can still stand up, how much we don't stand up
01:20so we thank God, it's too good human body
01:24If you are by the skeleton anatomy and personal training course, there are three main reasons which you should know.
01:33First of all, if we are a trainer or a trainer, or a general public, then we should have some of our own structure.
01:43And if you know something, there is a different motivation, a different attitude,
01:49to know more about that, to know more about it, to know more about it, to know more about it, to know more about it.
01:53The other thing is that our bones are helping our movements, our actions,
01:59when we perform exercise,
02:02when we perform our bones, which is a stress and strain,
02:07how our bones can react, how we react to the stress,
02:12we can understand the bone anatomy and skeleton anatomy.
02:18The other thing is that if we perform exercise or sports or injury,
02:23then we should understand the skeleton anatomy.
02:28Coming back to our topic,
02:29when we are born, our total number of bones is about 270.
02:34And just as we are growing, we are mature, we are adult,
02:39the total number of bones decreases by 206.
02:43Now we are thinking about 270-206,
02:48which is how we grow our bones.
02:50We are mature,
02:52we are mature,
02:53we are mature,
02:54we are mature,
02:55we are mature,
02:56we are mature,
02:57we are mature.
02:58from 270 degrees, from 206 degrees to 206 degrees.
03:03Our skeleton is divided by two parts.
03:06The first is Axial Skeleton and the second is Appendicular Skeleton.
03:10In this video, in Part 1, in Lesson No. 9,
03:14in this whole video, Axial Skeleton.
03:17And the next video is Part 2,
03:20in this lesson,
03:21in Appendicular Skeleton.
03:24Now let's talk about Axial Skeleton.
03:27Axial Skeleton is our Head,
03:29which we call the Skull,
03:30and the Neck,
03:31and the next thing is the Trunk.
03:33The Trunk means the upper part.
03:35The Trunk means that we have two things.
03:37The first is the Rib Cage,
03:38and the second is the Vertebral Column.
03:40The Appendicular Skeleton,
03:42which we study with our hands,
03:43which we study with our hands,
03:44which we study with our hands.
03:46So in this video,
03:47in this video,
03:48we talk about Axial Skeleton.
03:50The Axial Skeleton is a mature Axial Skeleton.
03:54There are 80 bones.
03:56The seet bone total.
03:58Our Axial Skeleton is a upright posture,
04:01we lay around the height,
04:02and we meet up,
04:03and we may be able to sit down.
04:04Our Axial Skeleton is a great.
04:06This is the Axial Skeleton.
04:07The principal is the upper extremities.
04:09The weight is the hip joint.
04:11The first part is our skull.
04:14is our skull, which is the total of 22 bones, which is the total of 14 facial bones,
04:22which is the total of 8 cranial bones, which is the total of 8 cranial bones.
04:36The total of our skull is the total of 22 bones, which is the total of 14 facial bones and 8 cranial bones.
04:45If we go to the axial skeleton, then we will get ribcage.
04:49In the ribcage, there are 24 ribs and 1 sternum.
04:52So, here are the total of 25 bones.
04:55This is the total of 24 ribs.
04:58This is the total of 12 ribs.
05:01So, 12 into 2, 24 ribs.
05:04In ribs 12 pairs, there are 7 pairs, which are directly sternum from the sternum.
05:09In pairs, we call true ribs.
05:11There are 3 pairs pairs on the same, which are filled with sternum from the sternum from the sternum,
05:17like the eight pairs.
05:19We call false ribs.
05:20In pairs, we call two pairs that are directly attached.
05:23In pairs, we call floating ribs.
05:25Just as the same, there are 7 pairs of ribs that are directly attached.
05:31There are three pairs of fused and then sternum attached to the sternum
05:35and there are two pairs of pairs here
05:37which are not attached to the sternum
05:39or floating position.
05:40This way, floating ribs can be said.
05:41So, here rib cage has total 25 bones
05:44where there are 24 ribs and one sternum.
05:47So, our total is 25 bones.
05:49If we turn this skeleton,
05:51we will get our vertebral column.
05:54In the vertebral column, total 33 bones
05:57which we call the back bone or the spine.
06:01In this image, this is our vertebral column.
06:05Here you will see,
06:06there are small disc in the form.
06:08Like the chain, the cycle is the same.
06:11Our body is the back bone.
06:13There are small disc.
06:14This is a small unit.
06:16This is a vertebral column.
06:18Here are total 5 bones.
06:22I will explain.
06:23Here you see C1-C7 vertebral.
06:26This is cervical.
06:27Here you see TH1-T12 to see.
06:32This is thoracic.
06:34Here you see L1-L5 to see.
06:37This is lumbar.
06:38Here you see green color.
06:40This is sacral.
06:42Here you see 5 bones.
06:44Here you see.
06:46This is sacrum.
06:49This is sacrum.
06:50Here you see sacral.
06:52Here you see red bone.
06:55We call the bone.
06:56Here we call thefilm half.
06:57There 4 bones.
06:58We call it the coccyx.
06:59He also
07:21so if we have all the vertebrae total here we have 33 here we have 7 cervical 12 thoracic
07:305 number 5 sacrum and 4 coccyx so total our 33 bones here we have total number of bones
07:4033 and if we have all the bones total total total total total total total total total total total
07:47the bone system for one intences those are total total total the total total total total total total total total total total total total total total total total totalาร obt end
08:06So, in the Axial Skeleton, we have 80 bones.
08:09We have a part 2 of this lesson to see appendicular skeleton
08:14where there are many bones.
08:15So, we have a video that you don't want to miss.
