Upper Wing Muscles
What structures do these correspond to in humans?
The upper and lower wing correspond to the upper arm, elbow and lower arm in a human.
What happens when you tug on these muscles?
When you tug on the muscles one relaxes (the tricep which is coloured green in the image to the left) and one contracts and hardens, (the bicep, coloured orange) If you pulled back the other way the opposite muscles would flex and extend.
What muscles to they correspond to in humans?
The muscles correspond to the biceps and triceps in the human upper arm.
In the image above the tricep is the extensor and the bicep is the flexor. This is opposite when the arm is in the opposite direction.

Lower Wing Muscles
What happens when you tug on these muscles?
The lower wing is made of the ulnaris and radialis longus. When you tug from the wing-tip upwards the ulnaris contracts and the radialis longus extends. When you pull downwards the muscles swap and the ulnaris extends and radialis longus contracts.

What is the name of the tissue that connects muscle to bone?
The tissue is called a tendon.
Describe what it looks like.
A shiny white strip that connects the bone to the muscle. It is visible in this photo.
What is the tissue that connects the bones in the elbow joint called?
The tissue is called a ligament.
What kind of joint is this?
The elbow joint is called a hinge joint.
The tissue is called a tendon.

What kind of joint connects the wings at the shoulder?
A ball and socket joint. You can see the ball in this photo.
Describe the cartilage that lines the joint.
Cartilage is a hard and slippery substance that coats the bone: kind of like a shell except a bit softer. It reduces friction between the bones in a joint.
What bones are found in the chicken wing?
The humerus, radius and ulna are found in the chicken wing.

What is osteoporosis?
Osteoporosis is a condition where the bones in your body become fragile and brittle. It occurs from loss of minerals like calcium and vitamin D, which lowers the density of the bone. If you suffer from osteoporosis it can mean you are more likely to break bones, even from a minor bump or fall. After the third time I broke my arm my doctor first thought I had osteoporosis, but luckily I don't. Osteoporosis occurs most commonly in the hip, wrist, spine, rib and arm.
What is arthritis?
Arthritis is a disease that causes inflammation and pain to the joints. It is when the cartilage that surrounds the ends of bones in joints is worn, resulting the bones rubbing against each other causing pain and damage. This results in joint weakness, instability and in some cases deformities. Arthritis commonly occurs with age, although 2.4 million of people with arthritis are between 25 and 45.
What happens when you break a bone and how does it heal?
There are many types of broken bones. When you break a bone the bone can snap (normal), crack (green stick) , pierce the skin (compound) break in multiple spots (comminuted), or even be caused by stress or trauma. When the bone is broken it is taken to a doctor, where it is rearranged back into place and left in a plaster or fiberglass cast for 4-6 weeks (sometimes longer in severe cases) so it will repair and grow back into normal. If the bone is broken extremely badly or if it is a compound fracture surgery may be required, where pins or screws may be inserted to hold the bone in place whilst it heals.
What happens when you injure a muscle and how does it heal?
A muscle or tendon will tear when injured, this is called a strain, or a pulled muscle. Muscles might tear, become inflamed, and sometimes swell and bruise. To treat an injured muscle, stop what you are doing if you have injured it from physical activity, apply ice to the affected area, strap and elevate it. This process is sometimes referred to as RICE: Rest, Ice, Compression and Elevation. Painkillers and anti-inflammatory medicines can also be taken if the injury is causing a lot of pain and swelling. If it is a 3rd degree strain, (where the muscle has completely torn in two,) the patient should immediately see a doctor. 1-6 weeks after the injury, physio and stretches is recommended to return the muscle to its full strength and flexibility.
