These flashcards cover key concepts related to bone tissue and the functions of different types of bone marrow.

Spongy bone

The type of bone tissue that contains red bone marrow.

Red bone marrow

Produces white blood cells (WBCs), red blood cells (RBCs), and platelets.

Yellow bone marrow

Stores triglycerides and consists primarily of adipose cells.

Diaphysis

Osteoclasts

Cells responsible for the re-absorption of bone.

Endosteum

Lines the medullary cavity and surrounds the bone surface.

Growth in long bones of children

Occurs at the ends of the epiphyses.

Osteocytes

Regulate the calcium metabolism of adult bones.

Nutrients for bone matrix

Calcium and phosphorus.

Collagen

The protein that is part of the bone matrix.

Osteogenic cells

Develop into osteoblasts.

Red bone marrow is found in flat bones.

Osteoblasts

Produce new bone matrix for growth or repair.
