The correct spelling of the Latin term "centrum medullare" refers to the "medullary center" of a structure. The phonetic transcription of the word is /ˈsɛntrəm məˈdʌlɛːrɛ/. The first syllable "sen" is pronounced with a short "e" sound, followed by "trum" with the "u" sound. "Medullare" is pronounced with a long "a" sound in the first syllable, followed by "dul" and "are." Accurate spelling of Latin terms through phonetic transcription helps prevent confusion in scientific writing and communication.
Centrum medullare is a Latin term used in anatomy and biology to refer to the central portion or core of a structure, particularly in relation to bone anatomy. It specifically pertains to the central part or core of the vertebral bone, also known as the centrum, which is the cylindrical body forming the main bulk of a vertebra.
Located at the front of the vertebra, the centrum medullare is surrounded and protected by the vertebral arch, which consists of several bony processes, such as the pedicles and laminae. The main function of the centrum medullare is to provide support and stability to the vertebral column, acting as a weight-bearing structure.
Within the centrum medullare, there is a central cavity called the vertebral canal, which accommodates and protects the spinal cord. This canal is surrounded by the spongy bone tissue called cancellous or trabecular bone, which is filled with bone marrow. The bone marrow present in the centrum medullare is responsible for producing various types of blood cells, including red blood cells, white blood cells, and platelets.
Overall, the centrum medullare is a crucial component of the vertebral bone, providing structural support, protecting the spinal cord, and facilitating hematopoiesis (the formation of blood cells).

The term "centrum medullare" is derived from Latin roots.
- The word "centrum" comes from the Latin word "centrum", meaning "center" or "middle".
- The word "medullare" is derived from the Latin word "medulla", which refers to the innermost or central part of a structure. It can also mean "marrow" in the context of bones.
So, together, "centrum medullare" refers to the central or middle part of something that resembles or pertains to marrow. In anatomy, it specifically refers to the central part of the spinal cord.
