Retinal purple rhodopsin visual purple - a red photopigment in the retinal rods of vertebrates.

Definition of biology rod. A thin straight piece or bar of material such as metal or wood often having a particular function or use as. Any of the long rod-shaped photosensitive receptors in the retina responsive to faint light compare cone sense 2a. A rod-shaped light-sensitive cell lying in the more peripheral parts of the RETINA in the vertebrate eye.

ROD is listed in the Worlds largest and most authoritative dictionary database of abbreviations and acronyms ROD - What does ROD stand for. Shapes of viruses are predominantly of two kinds. Dictionary of Optometry and Visual Science 7th edition.

Retina - the innermost light-sensitive membrane covering the back wall of the eyeball. Medical Definition of rod 1. Any organism with a notochord is a Chordate.

Any rod-shaped or cylindrical bacterium of the genus Bacillus comprising spore-producing bacteria. Rods are particularly associated with vision under conditions of low illumination and they occur in large numbers in nocturnal animals. A straight slim mass of substance.

One of two types of visual cells cylindrical segments that contain rhodopsin. Each domain contains a collection of organisms with similar properties and evolutionary histories as scientists have organized them. Dissociates into retinene by light.

In biology a domain refers to the largest of all groups in the classification of life. Together with the cones they form the light-sensitive elements of the retina. A receptor capable of reacting when stimulated by light such as the rods and cones of the retina.

Rod - definition of rod by The Free Dictionary Define rod. Visual cell - one of the cells of the retina that is sensitive to light. They are not capable of colour discrimination and their visual acuity is poor compare CONE CELL.

Rod cell - a visual receptor cell that is sensitive to dim light. A rod or stick that has a notch in the top used to draw out natural fibres for spinning into thread and a long narrow body around which the thread is wound when spun one of the thin rods or pins bearing bobbins upon which spun thread is wound in a spinning wheel or machine. Size of Bacteria Bacteria are microscopic organisms that are less than 3 micrometeres μm in size.

One subgroup of microglia rod microglia have been observed in a number of pathological conditions however neither a function nor specific morphology has been defined. Vertebrates in the Phylogenetic Tree. They are not capable of colour discrimination and their visual acuity is poor compare CONE CELL.

A straight slender pole or bar 2. Called also retinal rod. Bacteria can also be other shapes such as filamentous long and thin square star-shaped and stalked.

Noun plural bacilli buh-sil-ahy. Bacteria are measured using a calibrated slide under a compound microscope or using an electron microscope. Diplobacilli are two bacilli arranged next to each other and streptobacilli are chains of bacilli.

Rod synonyms rod pronunciation rod translation English dictionary definition of rod. There are currently 3 agreed groups at this level the Archaea domain Bacteria domain and Eukarya domain. Size of cocci range from 05 to 3 μm and the size of a rod shaped bacteria range from 015 to 2 μm width to 05 to 20 μm length.

It is continuous with the optic nerve. Historically rod microglia have been described intermittently as cells with a sausage-shaped soma and long thin processes which align adjacent to neurons. A rod-shaped light-sensitive cell lying in the more peripheral parts of the RETINA in the vertebrate eye.

See also eye and vision. Rods are particularly associated with vision under conditions of low illumination and they occur in large numbers in nocturnal animals. Rods or filaments so called because of the linear array of the nucleic acid and the protein subunits and spheres which are.

Examples of implantable devices include spinal rods bone plates and bone fixation cords. Like cocci bacilli can be solitary or arranged together. Vertebrate characteristics begin at the notochord a supportive elastic rod found on all Chordates.

A method for determination of mechanical integrity of bone includes embedding a threaded rod into the bone extracting the threaded rod out of the bone and measuring the force required to extract the threaded rod from the bone wherein the force required to extract the threaded rod is indicative of the mechanical integrity of the bone. When this notochord becomes covered with bony material during fetal development the result is a vertebrate. Bacilli are rod-shaped bacteria.
