What is a ring shaped object called?
annulus
What is a circle with a little circle in it called?
An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
How do you find the area of a ring?
If R and r are the outer and inner radii of the annulus (ring) then the area is pi*(R2 - r2), which is simply the area of the big disc minus that of the little disc.
What 2 dimensional shape has the most lines of symmetry?
A circle or annulus. Each of its infinite number of diameters is an axis of symmetry. Plus there is the line through its centre and perpendicular to the plane of the circle.
Does mean mean average?
No, but sometimes "average" means "mean" - when it doesn't mean median, geometric mean, or something else entirely.
What is a basal annulus?
A basal annulus is a mushroom with an annulus located near the bottom of the stem.
When was Monetaria annulus created?
Monetaria annulus was created in 1758.
What is the space between two concentric circles called?
Annulus
What is the function of the annulus?
what is the function of the annulus, nucleus, neurovascular capsule, and cartilaginous endplate
Is the cross section of hollow cylider is called annulus?
Yes. An annulus is a circular disc with a concentric circular disc cut out of it.
What is annulus?
We all have cartilaginous discs that separate the spinal bones, or vertebraes, from each other. These discs allow for movement within the spine. Each disc has a fibrous outside, called the annulus fibrosus, and a liquid center, called the nucleus pulposus. Think of a disc as a jelly donut. The jelly is the nucleus and the donut is the annulus. If the fibers of the inner annulus tear, the jelly nucleus, which is tightly held in the center, follows the path of least resistance and pushes towards the wall of the annulus. When this happens, the wall of the annulus is warped and appears to bulge or protrude. This is known as a protruding annulus or ,in other words, a bulging disc. If the annulus continues to weaken and tear, the nucleus has potential to eject from the disc. The annulus will no longer be bulging, as the wall has opened and the jelly nucleus has squeezed out or herniated. This now constitutes a herniated disc.
What is the annulus on a mushroom for?
The annulus on a mushroom, also known as the ring, is a structure that helps protect the developing gills and spores. It is formed by a partial veil that covers the young gills as the mushroom grows. The annulus eventually breaks away from the stem as the mushroom matures.
What is a ring shaped object called?
annulus
What is left foraminal annular tear?
A left foraminal annular tear is when the annulus fibrosus rips or tears. The annulus fibrosus is the tough exterior of the intervertebral disc.
What does it mean if I have slight bulging of the annulus at L5-S1 I have a lot of pain there.?
It means you have a slight herniation/slight bulging of the disc at the L5-S1 level of your spine.
What is the strong fibrous tissue outer periphery of the intervertebral disk called?
The strong fibrous tissue outer periphery of the intervertebral disk is called the annulus fibrosus.
What does multifocal bulging of the annulus fibrosis mean?
The annulus is a part of the spinal structure, specifically the outer fibers. When the annulus is damages, normally through aging (degenerative) or trauma, it allows the cervical disc, a gel-like material to expand. The more damage to the annulus, the more significant the bulge. In the worst cases, the disc "herniates" and may cause pressure on the nerve roots which run through the spine. In the neck (cervical spine), effected nerves run to the upper extremities. Therefore, if a bulging disc impinges on a nerve root in the cervical spine, it usually results in radiating pain, numbness and/or weakness in the arms. Surgery is sometimes necessary to remove the disc or otherwise relieve the pressure on the nerve root.
