Transcript of Principles of Anatomy and physiology in sport.

BTEC National Level 3 Principles of Anatomy and Physiology in Sport By the end of this lesson you will be able to know the structure and function of the skeletal system.
You will also complete the following tasks:
Research label the skeleton using the appropriate terms.
Complete the joint movement worksheet.
Label the X ray pictures and name the bones.
Would we be able to live without a skeleton?

The skeleton gives us shape and structure and permits us to operate on a daily basis.
The skeleton also allows us to move around and protects crucial organs .
Bones produce blood cells within bone marrow and store minerals which are released on a daily basis. The Human Skeleton Do you think this statement is true or false?
So what happens to the bones after birth? Explain your answer. FACTS:Adults & Babies A fully grown adult has 206 bones. However, you are born with over 270 bones. Facts: The female pelvis is usually shallower and wider.
Why do you think this is? Differences between males and females Female skeletons are more delicate than males . Male cranium or (skull) are more robust. Male chin are more prominent than female. Male and female differences. Bones are made up of various different elements.
Initially skeletons take shape as cartilage; this later calcify and develops following birth.
The main element that make up bone is called osseous tissue.
Osseous tissue is mineralised calcium phosphate. Other tissue such as marrow, cartilage and blood vessels are contained within the structure. What are bones made up of ? As we age so do our bones. Even though cells are constantly replaced and no cell is more than 20 years old , they are not replaced with brand new cells. The cells contain error in their DNA. The error in the DNA cause bones to weaken as we age. This increases the risk of conditions such as osteoporosis, weakened bones, and reduced movement ability.
So what do you think can we do to prevent this? As we age... Porus Bone What do you notice about the bone ? When we are born, many of your bones are still soft and are not fused, this process occurs later in childhood. The non-fusal at birth is to allow the skull to flex and permit growth.
The skull is made up of seven separate plates and over the first two years these plates fuse together and ossify.
The plates suture together early on but the anterior fontanel takes the longest to heal.
Other bones in the sacrium do not fuse until late teens or early twenties, but the cranium becomes fully fused around age two. Skull Development How Joints work.. To explore the structure and function of the skeletal system.
P1: Describe the structure and function of the skeletal system.
P2: Describe the classification of joints. Aim Objective Using the Xray pictures and post it notes label the bones shown in the Xray.
Label the skeleton.
Name the different joints.
Explain or demonstrate how they move.
Extension label the picture skeleton. Complete the worksheet on the structure and function of the skeletal system. Activity What is the name of the longest bone in the body? Long Bones Bone Anatomy Ossification is the term used to describe the creation of bone from cartilage.
A joint is the term used to describe where two or more bones meet.
The function of the skeleton are shape, movement, blood production, and mineral storage.
Bones grow at their growth plates.
The different type of joints include fixed, slightly moveable and moveable/synovial. Summary Flexion: Movement of 180-30 degrees.

Extension: Movement of 30 -180 degrees.

Pronation: Facing up and down movement.

Supination: The facing down to up movement.

Dorsiflexion: Movement upwards towards shin.

Plantar flexion: Moving the foot in a downward action. Joint movement Adduction: Movement towards the midline of the body. Abduction: Movement away from the midline of the body. Circumduction: Movment of the limb in a circular action. Rotation: The limb moves in a circular movement towards the midline of the body. Inversion: Soles of the feet are facing each other. Look at the two pictures and write down the similarity between the bones in the hand and foot. The similarity between hands and feet.
