[1] A disc protrusion is a medical condition that can occur in some vertebrates, including humans, in which the outermost layers of the anulus fibrosus of the intervertebral discs of the spine are intact but bulge when one or more of the discs are under pressure. Many disk abnormalities seen on MRI that are loosely referred to as "herniation" are
Foot processes vs. lamellipodia and filopodia [ edit ] The difference between foot processes, and lamellipodia , which are broad sheet-like protrusions, and filopodia , which are long slender pointed extensions, is that lamellipodia and filopodia are especially significant for cell movement and migration , and they are "macro" membrane protrusions.
An intervertebral disc (British English), also spelled intervertebral disk (American English), lies between adjacent vertebrae in the vertebral column.Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.
Disc herniation can occur in any disc in the spine, but the two most common forms are lumbar disc herniation and cervical disc herniation. The former is the most common, causing low back pain (lumbago) and often leg pain as well, in which case it is commonly referred to as sciatica .
There is a disc between each of the vertebrae in the spine. A healthy, well-hydrated disc will contain a great deal of water in its center, known as the nucleus pulposus, which provides cushioning and flexibility for the spine. Much of the mechanical stress that is caused by everyday movements is transferred to the discs within the spine and ...
Extrusion of liposomes occurs at a uniform size, based on the pore size in the polycarbonate membrane. [10] This happens when the big vesicles are passed through the cell membrane with a nanopore size specified in size several times [ 10 ] due to the extrusion of polycarbonate membranes having uniform and vertical nanopore distribution on the ...
The death-inducing signaling complex (DISC) is a multi-protein complex formed by members of the death receptor family of apoptosis-inducing cellular receptors. [1] A typical example is FasR, which forms the DISC upon trimerization as a result of its ligand binding. The DISC is composed of the death receptor, FADD, and caspase 8. It transduces a ...
There is a variety of strong support for the ability of the Ndc80 complex to directly associate with microtubules and form the core conserved component of the kinetochore-microtubule interface. [66] However, formation of robust kinetochore-microtubule interactions may also require the function of additional proteins.
