Learning Outcome: To be able to identify the bones of the body, the function of the skeleton and to know what different types of bones are.
206 Bones in a human body.
200 Joints in a human body.
The skeleton is the body connective tissue that makes up general framework of the body.
Support: Give support for organs and tissue so they don’t collapse.
Protection: Provides protections for vital organs such as the heart and lungs.
Supply of red blood cells:Supplies red and white blood cells which are produced in marrow (Long Bones - Humerus, Femur).
Movement: Where bones meet, joints are formed, and in combination with muscles, it creates movement.
Storage: Minerals are stored in bones (Calcium).
The Axial skeleton consists of the centre of the body - the skull, the vertebrae and the ribcage.
The Appendicular skeleton consists of the outer body - arms, legs, shoulder girdle and pelvic girdle.
Types of bones
Long bone - Humerus, Femur
Flat bone - Bones of the skull
Irregular - Vertebrae
Short bone - Carpals, Tarsals

Learning Outcome: Understand what quality performance means. Be able to describe a quality performance and be able to break a performance down to sequences.
‘Quality’ - is the standard of something as measured against other things of a similar kind, the degree of excellence of something.
Notes for discuss:
Grip - Space out fingers, make sure thumb is inline with your arm
Release - Index finger touches the discuss last, snap at the hips and left arm, 2 swings after release
Stance - Side on,legs spread wide, transfer weight from back leg to front when swinging arm and pivot foot also whilst transferring the weight, left foot side on at the top of the circle.
Notes for shot put:
Start Position and Grip - Hold in finger tips, wide elbow, shot against neck under jaw line, facing back of the circle.
Balance - Arm up, lean forward, hop on right leg and extend left leg backwards.
Release - Side on, rotating core, follow through.
Release - Side on, rotating core, follow through.
Notes for Javelin:
Grip - High over right shoulder with an ‘American Grip’, point at target.
Stance - Hips straight to the throwing line.
Run Up - Accelerate smoothly towards the throwing line, keep hips straight to the line, the left leg crosses over the right as you pull the Javelin through in your final strides.
Release - Arm straight with hand at shoulder height, keep javelin straight inline with shoulder, plant left leg and push off right, bring arm up and forward, keeping elbow high, release when the javelin is as high as possible, follow through.

Learning Outcome: Be able to recall the types of joints, the types of movements and understand and describe the agonist and antagonist.
Pivot - Neck
Hinge - Elbow
Saddle - Carpometacarpal
Plane - Metacarpals
Condyloid - Carpals
Ball in Socket - Hip
Agonist - means the muscles contracting. Also known as the prime mover.
Antagonist - means the muscles relaxing.
Muscles must contract and relax in pairs to enable movement to occur. This pairing is known as the agonist and antagonist.
Antagonistic Muscle Group List
Bicep - Tricep
Back - Chest
Abs - Lower back
Shoulder - Chest/Back
Quadriceps - Hamstring
Tibialis Anterior - Gastrocnemius
Anterior Deltoid - Posterior Deltoid
Latissimus Dorsi - Deltoid
Pectoralis Major - Trapezius
Iliopsoas - Gluteus Maximus
Adductor Group - Gluteus Maximus

Learning Outcome: Demonstrate with confidence my understanding of joint types, joint movements, agonist and antagonist muscles.
Human Skeleton System
Skeleton protects internal organs, provides framework that allows us to stand upright and move. Stores minerals that our body need and produces blood cells.
Compact Bones - Dense, smooth and strong
Cancellous Bones - Spongy, lightweight
They both contain living cells which help make repairs if injured or broken.
Long bone has shaft called diaphysis (compact) and two bones called Periosteum.
Muscles and tendons attach themselves to the Periosteum.
Bone marrow stores fat, produces blood cell and is inside the medullary cavity inside the shaft.

Learning Outcome: Recall what i have been taught and be able to explain in detail how a body moves and why it moves the way it does.
When a movement occurs such as throwing a ball, just before the end of the movement, the antagonist will begin to contract. This Is one factor that prevents the joint from hyperextension.
The joint in the movement i'm discussing is the knee, also known as the hinge joint. The movement that is occurring in the knee joint is flexion to extension. The agonist is the hamstring and the antagonist is the Quadricep. This movement occurs when the knee is bending and in flexion because the muscles work in pairs. The hamstring contracts and pulls the joint so your knee bends. The next movement is extension, when going to release the ball. The agonist is the Quadricep and the hamstring is the antagonist.

Learning Outcome: Understand what the different types of muscles are and the difference between voluntary and involuntary muscles. Be able to explain movement in detail.
Muscle Definition - Muscles are long bundles of contractile tissue that formed bass of all movements and give contour to the body.
- Cardiac muscle cell - Around heart
- Skeletal muscle cell = enable us to carry movements - around bone
- Smooth muscle cell - around organ
Cardiac muscles, found in the heart, makeup walls of heard and are capable of quick and rapid movement and do not tire easy.
Involuntary
Skeleton muscles join bones together and are held in place by tendons.
Voluntary
Smooth muscles,found in the stomach and intestines, perform slow, long term contractions.
Involuntary
