PLASTIC CONTAINER FOR PACKAGING OPTICAL DISCS
Spindle (disk packaging)
In the context of computer supplies, the word spindle or cakebox may refer to a plastic container for packaging optical discs. It typically consists of a round base with a vertical rod (which matches the center holes of the disks) and a cylindrical cover made from polypropylene plastic.
Spindle apparatus         
  • This diagram depicts the organization of a typical mitotic spindle found in animal cells. Chromosomes are attached to [[kinetochore]] [[microtubule]]s via a multiprotein complex called the kinetochore. Polar microtubules interdigitate at the spindle midzone and push the spindle poles apart via [[motor protein]]s. [[Astral microtubules]] anchor the spindle poles to the [[cell membrane]]. Microtubule polymerization is nucleated at the [[microtubule organizing center]].
  • In the centrosome-mediated "search and capture" model (left), microtubules nucleated from centrosomes contact chromosomes by chance and become stabilized at kinetochores to form the spindle. In the chromatin-mediated "self-organization" model (right), microtubules are nucleated around the vicinity of mitotic chromatin and organized into a bipolar array by motor proteins.
  • Cartoon of the dividing epithelium cell surrounded by epithelium tissue. Spindle apparatus rotates inside the cell. The rotation is a result of astral microtubules pulling towards tri-cellular-junctions (TCJ), signaling centers localized at the regions where three cells meet.

In cell biology, the spindle apparatus refers to the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis, a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis, a process that produces gametes with half the number of chromosomes of the parent cell.

Aortic aneurism; Aortic Aneurysm; Coronary hemorrhage; Aortic aneurysms
An aortic aneurysm is an enlargement (dilatation) of the aorta to greater than 1.5 times normal size.

AORTIC VALVE DISEASE THAT HAS PHYSICAL BASIS IN INCOMPLETE OPENING OF THE AORTIC VALVE
Aortic Stenosis; Congenital stenosis of aortic valve; Stenosis of aortic valve; Aorta valve stenosis; Aortic supravalvular stenosis; Aortic calcification; Aortic valve stenosis; Aortic sclerosis
Aortic stenosis (AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. It may occur at the aortic valve as well as above and below this level.

AORTIC VALVE DISEASE THAT IS CHARACTERIZED BY LEAKING OF THE AORTIC VALVE OF THE HEART CAUSES BLOOD TO FLOW IN THE REVERSE DIRECTION DURING VENTRICULAR DIASTOLE, FROM THE AORTA INTO THE LEFT VENTRICLE
Aortic (valve) insufficiency; Quincke's sign; Hill's sign; Insufficiency of aortic valve; Aortic valve regurgitation; Traube's sign; Aortic valve insufficiency; Water-hammer pulse; Aortic incompetence; Aortic insufficiency
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.

The aortic bodies are one of several small clusters of peripheral chemoreceptors located along the aortic arch. They are important in measuring partial pressures of oxygen and carbon dioxide in the blood, and blood pH.

Wharve; Spindle-whorl; Spindle whorls
A spindle whorl is a disc or spherical object fitted onto the spindle to increase and maintain the speed of the spin. Historically, whorls have been made of materials like amber, antler, bone, ceramic, coral, glass, stone, metal (iron, lead, lead alloy), and wood (oak).

Spindle cell lipoma is an asymptomatic, slow-growing subcutaneous tumor that has a predilection for the posterior back, neck, and shoulders of older men.James, William; Berger, Timothy; Elston, Dirk (2005).
Supravalvular aortic stenosis         
HUMAN DISEASE
Supravalvar aortic stenosis
Supravalvular aortic stenosis is a congenital obstructive narrowing of the aorta just above the aortic valve and is the least common type of aortic stenosis. It is often associated with other cardiovascular anomalies and is one of the characteristic findings of Williams syndrome.

Abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than 50% larger than normal. They usually cause no symptoms, except during rupture.

Aortic valve

The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta. It is one of the four valves of the heart and one of the two semilunar valves, the other being the pulmonary valve. The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets. The aortic valve is the last structure in the heart the blood travels through before stopping the flow through the systemic circulation.
