The word "fibrocartilago intervertebralis" refers to the fibrocartilage found between the vertebrae in the spine. The spelling of this term may appear complex, but by using International Phonetic Alphabet transcription, the pronunciation becomes clearer. The correct pronunciation of this term is /faɪbroʊ karˌtɪleɪɡo ɪntərˌvɜːtɪˈbreɪlɪs/. The IPA system uses symbols to represent sounds in words, making it easier to understand their phonetic representations. Though not commonly used in everyday speech, understanding complex medical terms is crucial for healthcare professionals.
Fibrocartilago intervertebralis, commonly known as the intervertebral disc, is a type of cartilaginous structure found between the individual vertebrae in the spinal column. It serves as a cushioning and shock-absorbing material, playing a crucial role in enabling flexibility and preventing excessive friction between vertebrae during movements of the spine.
The fibrocartilago intervertebralis consists of two main components: the annulus fibrosus and the nucleus pulposus. The annulus fibrosus is the outer layer of the disc and is composed of fibrocartilage fibers arranged in concentric rings. It provides stability to the spine, preventing the nucleus pulposus from bulging out. The nucleus pulposus, on the other hand, is a gel-like substance located at the center of the disc. It is comprised mainly of water and specialized cells called chondrocytes, which contribute to its viscoelasticity and shock-absorbing properties.
The fibrocartilago intervertebralis functions to absorb and distribute forces applied to the spine during activities such as bending, twisting, and weight-bearing. It helps maintain the integrity and spacing of the vertebral column, ensuring proper alignment and weight distribution in the spine. Additionally, the disc allows for a certain degree of movement between adjacent vertebrae and acts as a flexible joint, facilitating smooth transmission of forces along the spine.
Due to its continuous exposure to stress and aging, the fibrocartilago intervertebralis is prone to degenerative changes, such as wear and tear, herniation, and bulging. These conditions can lead to pain, reduced mobility, and other neurological symptoms.
Intervertebral fibrocartilage or disc; a disc of fibrocartilage with a gelatinous center (nucleus pulposus), attached to each of two opposing vertebral bodies.

The word "fibrocartilago intervertebralis" is a Latin term used in anatomy to refer to the intervertebral fibrocartilage. Here is the breakdown of its etymology:
1. Fibro-: This prefix comes from the Latin word "fibra", meaning "fiber" or "thread". In anatomical terms, "fibro-" indicates the presence of fibrous tissue.
2. Cartilago: Derived from the Latin word "cartilago", meaning "cartilage". It refers to the tough, flexible connective tissue found in various parts of the body, including joints and the skeleton.
3. Intervertebralis: This term combines two Latin words - "inter", meaning "between", and "vertebra", referring to the bones of the spinal column or backbone. Therefore, "intervertebralis" means "between the vertebrae".
