Classification of Connective Tissues

Classification of Connective Tissues

The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense....

Functional Classification of Joints

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Classification of Bones

Classification of Bones

The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Background:

Intervertebral disc degeneration is a common condition.
Accurate classification is crucial for diagnosis and treatment.

Purpose of the Study:

To develop and validate a novel classification system for lumbar intervertebral disc degeneration.
To utilize apparent diffusion coefficient (ADC) values for quantitative assessment.

Main Methods:

Retrospective observational study of 100 patients.
Analysis of apparent diffusion coefficient (ADC) values from lumbar intervertebral discs.
Correlation of ADC values with established degeneration grading (Pfirrmann et al.) and hernia presence.

Main Results:

Mean ADC significantly correlates with lumbosacral disc degeneration severity.
Disc homogeneity differs between degeneration grades.
Mean ADC varies significantly with hernia presence in specific degeneration grades (grade 4: higher with hernia, grade 3: higher without hernia).

Conclusions:

A new, validated classification of lumbosacral disc degeneration based on mean ADC is presented.
This quantitative classification is recommended for radiologists, neurologists, and neurosurgeons.
