Final answer:
After removing the muscles from a dissection of a chicken thigh and hip, the intact tissue surrounding both bones is likely the articular cartilage and potentially ligaments such as the ligament of the head of the femur which join and support the bones in the hip joint.
Step-by-step explanation:
If you are performing a dissection of a chicken thigh and hip in a laboratory and you remove all the muscles and keep the tissue that joins the two bones intact, you are referring to the joint and specifically the structures such as the cartilage and ligaments that surround and support the bones.
The structure that is left intact after removing the muscles is likely the articular cartilage that is responsible for the smooth articulation of the joint surfaces. Moreover, the joint also produces synovial fluid that aids in reducing friction and wear in the joint. If someone is referencing tissue that spans between the bones, they could also be referring to ligaments, such as the ligament of the head of the femur, which connects the two bones but provides minimal support.
