What's the difference between saccule and sacculus?
Saccule
Definition:
(n.) A little sac; specifically, the sacculus of the ear.
Example Sentences:
(1) In the cis-trans axis of the Golgi apparatus the following compartments were observed: (a) On the cis face there was a continuous osmiophilic tubular network referred to as the cis element; (b) a cis compartment composed of 3 or 4 NADPase-positive saccules perforated with pores in register forming wells that contained small vesicles; (c) a trans compartment composed of 1 or 2 TPPAse-positive elements underlying the NADPase ones, followed by 1 or 2 CMPase-positive elements that showed a flattened saccular part continuous with a network of anastomotic tubules.

(12) The opposition line does not divide each macula simply down its midline; instead, the line divides the regions with thich bundles into nearly equal opposing areas, except for a remarkably abrupt large loop in the line in the anterior part of the saccule.
(13) Labeling with a polyclonal antibody to amylase was found in the Golgi saccules, immature and mature secretory granules, but not in the trans Golgi network.
(14) These last elements consisted of prosecretory granules attached to flattened, empty-looking saccules showing buds at their surface; detached, more-or-less fenestrated, flattened saccules; and shrivelled residual trans-tubular networks.
(15) Previous studies have demonstrated the existence of acoustic responses from the saccule in guinea pigs for stimulus intensities above 75 dB SPL.
(16) The results indicate that SER-derived vesicles, containing fat droplets, migrate from the apical cytoplasm of the absorptive cell and fuse with saccules or vacuoles of the Golgi complex.
(17) Histological examination of the temporal bones showed separation of otoconia from the otolithic membrane of the saccule and bleeding in the saccule in both conditions.
(18) Sacculations of the SR extend over the A-I junctions of the myofibrils, where they make specialized contacts (diads) with the TTS.
(19) In cultured immature MK from normal progenitors, both peptide components of GPIIb-IIIa appeared in the Golgi saccules and vesicles, and in the small precursors of alpha-granules, labeling both their membranes and their matrix.
(20) After 15 min, CF particles were seen in many small vesicles near the Golgi apparatus, but not in the Golgi saccules.
Sacculus
Definition:
(n.) A little sac; esp., a part of the membranous labyrinth of the ear.
Example Sentences:
(1) Pitlike surface structures seen in negatively stained whole cells and thin sections were correlated with periodically spaced perforations of the rigid sacculus.
(2) The auditory function of the sacculus in amphibians is confirmed and special attention is paid to functional heterogeneity of the receptor epithelium in the saccular maculae.
(3) evoked by sound stimuli were recorded intracellularly from large afferent eight nerve fibres in the sacculus of the goldfish (S1 fibres).
(4) These animals also had discrete collections of macrophages in colon or sacculus, mucosal and submucosal edema, and chronic inflammation of the colon.
(5) The sacculus most likely functioned as a basal framework on which O-8 and lipopolysaccharide assembled to form a flat sheet which is large enough to interact with individual distal ends of long tail fibers of a single phage particle.
(6) The shape of Escherichia coli is fixed by the form of the sacculus.
(7) The first step of otolith formation is an aggregation of organic clusters observed in the sacculus of the 15.5-day fetus.
(8) The occurrence of cytokeratins, vimentin, and desmin in the dome epithelia and adjacent non-dome epithelia in four locations of gut-associated lymphoid tissues (GALT) of adult and newborn rabbits (Peyer's patches, sacculus rotundus, caecal lymphoid patches and appendix) was studied with monoclonal antibodies, using the indirect immunoperoxidase technique.
(9) The murein sacculus of the organism is discussed in comparison with PG of other gram negative bacteria and marine or halophilic microorganisms.
(10) Chemical modification of the exposed amino or carboxyl groups was performed on whole cells, isolated S layers self-assembled in vitro, and cell wall fragments (S layer attached to the peptidoglycan-containing sacculus).
(11) This suggests that the sacculus normally influences mean vertical eye position and the perception of the subjective horizontal direction, both of which are gravity dependent.
