What is the name of the flexible sheet that interconnects the radius and ulna (and the tibia and fibula)?

검증된 단계별 안내

Understand that the problem is asking for the name of a specific anatomical structure that connects two long bones in the forearm (radius and ulna) and also in the lower leg (tibia and fibula).

Recall that the radius and ulna are the two bones of the forearm, and the tibia and fibula are the two bones of the lower leg, both pairs connected by a flexible sheet.

Identify that this flexible sheet is a type of connective tissue that allows for stability and slight movement between these bones.

Recognize that this structure is called an 'interosseous membrane,' which is a fibrous sheet connecting the shafts of the radius and ulna, as well as the tibia and fibula.

Conclude that the correct anatomical term for this flexible sheet is the interosseous membrane.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Interosseous Membrane

The interosseous membrane is a flexible, fibrous sheet of connective tissue that connects the shafts of two long bones, such as the radius and ulna in the forearm or the tibia and fibula in the leg. It helps maintain the proper spacing between the bones and provides a surface for muscle attachment.

Radius and Ulna Anatomy

The radius and ulna are the two long bones of the forearm. The radius is located on the thumb side, while the ulna is on the little finger side. Their relationship and connection via the interosseous membrane allow for forearm rotation and stability.

Tibia and Fibula Anatomy

The tibia and fibula are the two bones of the lower leg. The tibia is the larger, weight-bearing bone, while the fibula is thinner and positioned laterally. The interosseous membrane between them stabilizes the bones and serves as an attachment site for muscles.
