Globular and Fibrous Proteins

Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities. Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

Fibrous Proteins

Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...

Structural Joints: Fibrous Joints
0 Views •
2025
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints. Suture All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Simple and reproducible procedures are described for making three structurally distinct collagen assemblies from a common commercially available Type I collagen monomer. Native type, fibrous long spacing or segmental long spacing collagen can be constructed by varying the conditions to which the 300 nm long and 1.4 nm diameter monomer building block is exposed.
FAQs
The needle must traverse the annulus fibrosus, whose tough fibers encircle the disc, before reaching the nucleus pulposus. This pathway provides access for contrast injection, sampling, or treatment delivery. Because the needle crosses protective disc tissue, clinicians must balance obtaining useful access with limiting additional stress or injury to the disc.
Imaging guidance allows clinicians to monitor the needle’s position as it passes through the annular fibers and enters the disc space. It also supports observation of the disc’s responses during the procedure. This information helps the operator maintain the intended pathway and interpret findings more reliably during diagnostic discography or selected intradiscal interventions.
The procedure can provide information about suspected discogenic pain and structural damage by combining access to the disc with monitored responses. Contrast medium may help characterize the disc, while tissue or fluid sampling can provide additional material for evaluation. These findings can support decisions about whether disc-related pathology warrants further clinical consideration or treatment.
Penetrating the annular fibers can stress or injure disc tissue, so the potential diagnostic or therapeutic value must justify the intervention. Careful patient selection helps focus the procedure on appropriate clinical questions, such as suspected discogenic pain. Sterile technique is also essential because the needle enters the disc space and must be introduced under controlled conditions.
With imaging guidance, the clinician directs a needle through the annulus fibrosus into the nucleus pulposus. Once access is established, the operator may inject contrast medium, collect tissue or fluid, or deliver treatment. Needle position and disc responses are monitored throughout, allowing the procedure to remain aligned with its diagnostic or therapeutic purpose.
Clinicians may consider this approach when direct information from the disc is needed to evaluate suspected discogenic pain, characterize structural damage, or guide an intradiscal intervention. Access permits contrast-based assessment, sampling, or treatment delivery that cannot be obtained without entering the disc space. Its use requires weighing these potential benefits against tissue stress or injury.
