This bone is called a scapula, or more commonly, a shoulder blade.
This is an amazing question. I'm just going to spout answers to what I think you might be asking, and we'll see if anything sticks.The triceps brachii is a "three-headed" muscle in the back of your arm, used to straighten it.The triangular bone behind your shoulder is the scapula, which connects your upper arm to your collar bone.On the back of the Great Seal of the United States (and subsequently on the back of the dollar bill) is a 13-level unfinished pyramid, with the Eye of Providence where the top would be.If you are on the bottom of a human pyramid, with people kneeling on your back, you form part of the base.
For 30 adults, you should plan on serving about 1/2 pound of tri-tip per person, accounting for bone and fat. This means you would need approximately 15 pounds of tri-tip. If you want to ensure there are leftovers or if your guests have hearty appetites, consider rounding up to 18-20 pounds.
The triangle shaped bone in your upper back is called the shoulder blade. This is learnt in health class.
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.
Scapula
The bone that is located between the upper and lower "leg bone" (the patella) is triangular shaped, not flat (the point of the triangle faces back), and is more square shaped when viewed head on than round. It's function is to help to keep the quadriceps tendon in line, not to protect the joint. If this is the homework question that it appears to be then I would have serious doubts about the person who asked it.
The bones of the mid and upper back are the thoracic vertebrae. The neckbones are the cervical vertebrate and the lower back bones are the lumbar vertebrae.
I'm saying the pelvis.
The scapula is either of two flat, triangular bones, each forming the back part of a shoulder in humans; shoulder blade
The bone that forms a broad triangle is the scapula, commonly known as the shoulder blade. It has a triangular shape with three edges: the superior, medial, and lateral borders, which contribute to the shoulder's structure and movement. The scapula connects the humerus (upper arm bone) to the clavicle (collarbone), playing a crucial role in upper limb mobility.
The upper knee. The patella is a small upside down triangle shape bone. It sits inside the tendon of the thigh muscles at the front of the knee resting in the patellar groove of the femur (thigh bone).
The scapula is the shoulder blade. This is located on the upper part of the back.
Sacrum
The shoulder is the scapula (Located on your upper back) and the humerus is the upper arm bone. You may also be referring to the ball and socket joint where the head of the humerus articulates with the glenoid fossa of the scapula.
