Disc-like structure

The Gould Belt is a structure consisting of clusters of massive stars. The Sun is situated not far from the center of that disc-like structure. The Gould Belt radius is about 300 pc. It is inclined at 18° with respect to the galactic plane. 

Platelet. Disc-like structure, 2-4 mm in diameter, found in the blood of all mammals and chiefly known for its role in blood coagulation. 

The postsynaptic nerve ending, which is usually the tip of an axonal dendrite, has its own set of proteins, which varies to some extent with the nature of the neurotransmitter. In excitatory cells the plasma membrane of the postsynaptic neuron is thickened to — 30—40 ran to form the "postsynaptic density," a disc-like structure of clustered receptors of two types, which extends 30 ran into the cytosol.593 594 Only single receptor channels are indicated in Fig. 30-20, but many receptors are present in the clusters594 595 as are other specialized proteins. One of these, designated... 

The peculiarities of the aggregation behaviour of surfactant molecules in non-aqueous media. It is admitted that the aggregates exhibit disc-like structures with small aggregation numbos (<20) [39,40]. Such aggregates would not swell with monomer solutions, but on the other hand, would be able to capture initiator radicals, thus decreasing the overall radical efficiency. 

Kinetoplast a structure at the base of the single flagellum of a trypanosome. The K. has a high affinity for basic dyes, and was first observed early in the 20th century by light microscopy. Electron microscopy shows that the K. is a disc-like structure in the matrix of the cell s single mitochondrion. The K. has attracted biochemical interest because it contains an unusual form of highly catenated DNA, known as kinetoplast DNA (kDNA). See Catenane.
