These diverticula make their appearance before the closure of the anterior end of the neural tube; [1] [2] after the closure of the tube around the 4th week of development, they are known as the optic vesicles. Previous studies of optic vesicles suggest that the surrounding extraocular tissues – the surface ectoderm and extraocular mesenchyme ...

The optic vesicles project toward the sides of the head, and the peripheral part of each expands to form a hollow bulb, while the proximal part remains narrow and constitutes the optic stalk. [1] [2] Closure of the choroidal fissure in the optic stalk occurs during the seventh week of development. The former optic stalk is then called the optic ...
The optic vesicles then develop into the optic cup with the inner layer forming the retina and the outer portion forming the retinal pigment epithelium. The middle portion of the optic cup develops into the ciliary body and iris. [7] During the invagination of the optic cup, the ectoderm begins to thicken and form the lens placode, which ...
The McKenzie method is a technique primarily used in physical therapy.It was developed in the late 1950s by New Zealand physiotherapist Robin McKenzie. [1] [2] [3] In 1981 he launched the concept which he called "Mechanical Diagnosis and Therapy (MDT)" – a system encompassing assessment, diagnosis and treatment for the spine and extremities.
Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess exudate and promote healing in acute or chronic wounds and second- and third-degree burns. The therapy involves the controlled application of sub-atmospheric pressure to ...
Billy Bob Thornton is more than happy to play a foul-mouthed Santa (“Bad Santa”) or a high school football coach (“Friday Night Lights”) or a NASA scientist (“Armageddon”), but one ...
Mechanotherapy is a type of medical therapeutics in which treatment is given by manual or mechanical means. Mechanotherapy is a general term for physical therapy modalities that exploit mechanobiology principles for tissue rehabilitation and regeneration using the application of specific mechanical forces.
