I think you mean the humerus. Its the bone in your upper arm. :)
Humerus
The bone at the top of the arm is called the humerus. It is the long bone that runs from the shoulder to the elbow.
The triangle-shaped bone in your upper back is called the scapula, which is also known as the shoulder blade. It is an important bone that connects the humerus (upper arm bone) to the clavicle (collarbone) and helps in the movement of the shoulder joint.
The humerus and clavicle attach to the scapula.
It's called the scapula
The biceps attach to the radius bone (near your elbow) on a small bump called the radial tuberosity, and the the humerus(near your shoulder). Hope that helps!
The humerous is a single large bone that extends from the elbow to the shoulder. It is sometimes called the 'funny bone' , because when struck in a certain way you can have a 'funny' nerve tingling sensation. Humour/ funny.
If you are referring to the bone that makes the shoulder, it is called the scapula
There are two bones in your arm, but if it's the longer one in your forearm then it's called the ulna.
The upper arm bone between elbow and shoulder.
The bone is called the scapula and the part of the scapula that articulates with the humerus is known as the glenoid fossa.
The synovial joint between the scapula and the humerus is a ball-and-socket joint. This joint allows for a wide range of motion, including rotation and circumduction of the arm. It is known as the glenohumeral joint.
