What's the difference between indigitation and invagination?
Indigitation
Definition:
(n.) The act of pointing out as with the finger; indication.
Example Sentences:
Invagination
Definition:
(n.) The condition of an invaginated organ or part.
(n.) One of the methods by which the various germinal layers of the ovum are differentiated.
Example Sentences:
(1) The invaginations were classified into four easily recognized types: regular, chunky, filigree, and ridge (present only in axon hillock regions).
(2) Two normal variants that could be confused with abnormalities were noted: (a) the featureless appearance of the duodenal bulb may be mistaken for extravasation, and (b) contrastmaterial filling of the proximal jejunal loop at an end-to-end anastomosis with retained invaginated pancreas may be mistaken for intussusception.
(3) A general hypothesis is presented for the positive regulation of the initiation of cell wall and cell membrane invagination in this organism.
(4) These cells show many pinocytic invaginations and subsarcolemmic vesicles.
(5) Electron microscopically, the tumor cell nuclei were oval or polygonal and sometimes slightly invaginated, with a few prominent nucleoli.
(6) Morphology of the mature spermatozoon is modified from that of the classic primitive or ect-aquasperm type by having 1) the acrosome embedded in the nucleus (the only known example within the Mollusca), 2) a deep basal invagination in the nucleus containing proximal and distal centrioles and an enveloping matrix (derived from the rootlet), 3) laterally displaced periaxonemal mitochondria, and 4) a tail extending from the basal invagination of the nucleus.
(7) By 7 days, vascular buds were present at the edge of the graft and invaginating into the islet tissue.
(8) Invaginating mesodermal cells of the lateral and ventral parts also form pseudopodia, and are in contact with the blastocoelic wall.
(9) The changes observed were alterations of the nucleus (fingerlike or fingerformed nuclei, nuclear invaginations, and intranuclear vesicular membrane bodies), changes of the mitochondries (number, polymorphy, and osmiophil bodies), as well as changes of lysosomes (myelin-shaped residual bodies).
(10) Thus intracellular free calcium may be regulated by a combination of energy-requiring extrusion and passive influx through receptor-operated calcium channels located in the invaginated vesicular membranes, with short diffusion distances to the actin-myosin filaments in the cytoplasm.
(11) In this investigation we present results suggesting that the phage nucleocapsid penetrates the host cytoplasmic membrane via a membrane invagination and an intracellular vesicle.
(12) In this active area which invaginates the neuronal cytoplasm, osmiophilic granules but smaller can be seen, similar to those in the neighbouring neuron.
(13) In order to determine the frequency and specificity of intranuclear cytoplasmic inclusions (invaginations), described by some as an important criterion for the cytologic diagnosis of thyroid carcinoma, 258 consecutive thyroid aspirates were reviewed.
(14) At the stage when each placode first becomes visible conspicuous differences have been seen in the surface morphology between those cells which will invaginate and form the placode and those which will remain on the surface of the head, forming the epidermis.
(15) The most common group of neurons within the gustatory zone contains both large (X1) and small (X3) members that possess deeply invaginated nuclear profiles.
(16) The majority of the choline acetyltransferase-immunoreactive neurons had fusiform, oval, or polygonal somata with somatic diameters greater than 20 microns and contained deeply invaginated nuclei surrounded by copious cytoplasm.
(17) In the last 8 years 15 cases of Meckel's diverticulum were observed, 6 of them with complications: three times inflammation (with two perforations), each once invagination, incarceration and occult bleeding from carcinoids.
(18) The development of invaginations and microvesicles in P. malariae-infected erythrocytes corresponded to the morphological alterations induced by P. vivax.
(19) The follicle-associated epithelium had invaginations and small vacuoles in the apical cytoplasm, whereas the interfollicular surface epithelium had numerous microvilli on its apical surface and large mucin granules in the apical cytoplasm.
(20) The normal red cells were biconcave disks in which chlorpromazine induced inward (negative) curvature: deep cupping (stomatocytosis) and multiple invaginations.
