The sigmoid notch (also known as the trochlear notch) is a large depression in the ulna bone that articulates with the humerus. It is a defining feature of the ulna.

An unpaired parasphenoid is a dagger-shaped or inverted T-shaped bone on the ventral side that forms the floor of the cranium. It is a long and flat membraned bone.

The pelvic girdle consists of two similar halves, which are known as ossa innominata. Each os innominatum is formed by three bones. The dorsal bone is known as ilium, antero-ventral bone is named as pubis and the ventral bone is called ischium.

Astragalus is not found in humans. 

Ligaments are the connective tissue which connect two bones to each other.

The stapes is the third bone of the three ossicles in the middle ear. The stapes is a stirrup-shaped bone, and the smallest in the human body. It rests on the oval window, to which it is connected by an annular ligament. 

Pigeon pose is primarily a deep hip opener, targeting the glutes and external rotators of the hip, not the shoulders.

An average adult human skeleton consists of 206 bones. Infants are born with more bones, many of which fuse together during growth.

The most common surgical repair for a torn ACL in dogs is the TPLO (Tibial Plateau Leveling Osteotomy). This procedure involves cutting the tibia and rotating the bone to change the angle of the joint, which stabilizes the knee without needing the ligament itself.

The 'funny bone' is not a bone at all, but the ulnar nerve, which runs along the humerus bone and is sensitive to impact.

The Anterolateral Ligament (ALL) was formally described and identified as a distinct structure in the human knee by surgeons in 2013.
