Bone Marrow and Hematopoiesis (Page 1 Notes)

Vocabulary flashcards covering bone marrow, hematopoiesis, and marrow distribution in children versus adults.

Bone marrow

Myeloid tissue (reticular connective tissue) within bone; site of hematopoiesis.

Hematopoiesis

Blood cell formation.

Red bone marrow

In children, red marrow is present in all bones and actively forms blood cells.

Yellow bone marrow

Mostly adipose tissue; replaces red marrow with age.

Epiphysis

Ends of a long bone (e.g., humerus, femur).

Long bone

A bone with a shaft and two ends; contains epiphyses at its ends (e.g., humerus, femur).

Flat bones (adult marrow distribution)

In adults, red marrow is found in flat bones of the skull, ribs, sternum, vertebrae, and pelvis.

Adipose tissue

Fat tissue; makes up yellow bone marrow.

Reticular connective tissue

The supportive stroma of bone marrow; network of reticular fibers.
