Costovertebral joints, the articulations that connect the heads of the ribs with the bodies of the thoracic vertebrae; Costovertebral angle, the acute angle formed on either side of the human back between the twelfth rib and the vertebral column; Costovertebral angle tenderness, a medical sign of renal infection or renal stone
The costovertebral joints are the joints that connect the ribs to the vertebral column. The articulation of the head of rib connects the head of the rib and the bodies of vertebrae . The costotransverse joint connects the rib with the transverse processes of vertebrae.
The lens is located towards the front part of the vertebrate eye, called the anterior segment, which includes the cornea and iris positioned in front of the lens. The lens is held in place by the suspensory ligaments (Zonule of Zinn), [1] attaching the lens at its equator to the rest of the eye [2] [3] through the ciliary body.
The costovertebral angle (Latin: arcus costovertebralis) is the acute angle formed on either side of the human back between the twelfth rib and the vertebral column. [ 1 ] The kidney lies directly below this area, so is the place where, with percussion ( Latin : sucussio renalis ), pain is elicited when the person has kidney inflammation .
Monocular vision is known as seeing and using only one eye in the human species. Depth perception in monocular vision is reduced compared to binocular vision, but still is active primarily due to accommodation of the eye and motion parallax. The word monocular comes from the Greek root, mono for single, and the Latin root, oculus for eye.
With vision in fish and amphibians, the lens is fixed in shape, and focusing is instead achieved by moving the lens forwards or backwards within the eye using a muscle called the retractor lentus. [54] In cartilaginous fish, the suspensory ligaments are replaced by a membrane, including a small muscle at the underside of the lens. This muscle ...
A scleral lens, also known as a scleral contact lens, is a large contact lens that rests on the sclera and creates a tear-filled vault over the cornea.Scleral lenses are designed to treat a variety of eye conditions, many of which do not respond to other forms of treatment.
The absence of this lens left the patient highly hyperopic (farsighted) in that eye. For some patients the removal was only performed on one eye, resulting in the anisometropia / aniseikonia. Today, this is rarely a problem because when the lens is removed in cataract surgery, an intraocular lens, or IOL is left in its place. [citation needed]
