the brachial artery
your elbow
your biceps contract and your triceps relax
The elbow is a hinge joint. When you think about it, you can only bend your elbow back and forth. Think about your wrist, that's a gliding joint. It moves in a completely different way than your elbow.
When you bend your elbow, the biceps muscle contracts. At the same time the antagonist muscle, that is the triceps muscle relaxes in synchronized manner. Vise verse action take place, when you straighten the arm at the elbow. Triceps contracts and biceps relaxes.
They help to not allow the tendons to stretch backwards. With the bones there, you can only bend the elbow one way.
LISTENENING TO THE HEART GIVES THE APICAL PULSE. FEELING ON THE INSIDE OF THE ARM AT THE BEND OF THE ELBOW IS THE BRACHIAL PULSE.
hinged.......
An elbow is a joint that helps you bend your arm.
It is a little feather that sticks out, located at the bend of the elbow, but is in line with the wing. You can see it when the budgie has his/her wings in.
It is the radius of bend of the elbow with reference to a point,the point is determined by the intersection of two lines from the elbows socket end (which makes the shape of one quater of a circle). The bend ie; 1.5d,3d,5d,10d is determined from that point of intersection as a multiple of elbows diameter.
No, everyone has an elbow so that their arm can bend.
