Question

fibrous cords of tissue that attach bone to bone: ligaments
the ribs: periosteum
the outer membrane of a bone: choose
bones that are made of spongy tissue: also called trabecular bones: choose
the production of blood cells in the bone marrow: choose

Explanation:

Match fibrous cords connecting bone to bone

The description refers to fibrous connective tissues that link bones together at joints. These structures are known as ligaments.

Match the ribs

The ribs are a set of bones that form the protective cage of the thorax. In the context of bone classification by shape, ribs are classified as flat bones.

Match the outer membrane of a bone

The tough, fibrous membrane that covers the outer surface of all bones (except at the joints of long bones) is called the periosteum.

Match bones made of spongy tissue

Bones that are composed of spongy (trabecular) bone tissue covered by a thin layer of compact bone, and are roughly equal in length and width, are classified as short bones. Examples include the bones of the wrist (carpals) and ankle (tarsals).

Match blood cell production in bone marrow

The biological process of producing all types of blood cells, which occurs primarily within the red bone marrow, is called hematopoiesis (or hemopoiesis).
