Oogenesis in Xenopus laevis (Daudin). I. Stages of oocyte development in laboratory maintained animals
Tập 136 Số 2 - Trang 153-179 - 1972
AbstractOogenesis in the anuran Xenopus laevis can be divided into six stages
based on the anatomy of the developing oocyte. Stage I consists of small (50 to
100 μ) colorless oocytes whose cytoplasm is transparent. Their large nuclei and
mitochondrial masses are clearly visible in the intact oocyte. Stage II oocytes
range up to 450 μ in diameter, and appear white and opaque. Stage I and II are
bot...
Stages of oocyte development in the zebrafish, Brachydanio rerio
Tập 218 Số 2 - Trang 203-224 - 1993
AbstractOocyte development has been divided into five stages in the zebrafish
Brachydanio rerio, based on morphological criteria and on physiological and
biochemical events. In stage I (primary growth stage), oocytes reside in nests
with other oocytes (Stage IA) and then within a definitive follicle (Stage IB),
where they greatly increase in size. In stage II (cortical alveolus stage),
oocytes are...
The histogenesis of cartilage and bone in the long bones of the embryonic fowl
Tập 40 Số 3 - Trang 417-459 - 1925
AbstractThe development and cytology of cartilage and bone in the limbs from the
fifty‐second hour of incubation to the first day after hatching are
described.The chief points of interest arising from this study are: (1)
Chondroblasts when liberated during cartilage resorption die and disintegrate.
(2) All the long bones possess structures which, though not undergoing
independent ossification, are...
Skeletal indicators of locomotor adaptations in living and extinct rodents
Tập 269 Số 11 - Trang 1387-1411 - 2008
AbstractLiving rodents show great diversity in their locomotor habits, including
semiaquatic, arboreal, fossorial, ricochetal, and gliding species from multiple
families. To assess the association between limb morphology and locomotor
habits, the appendicular skeletons of 65 rodent genera from 16 families were
measured. Ecomorphological analyses of various locomotor types revealed
consistent diffe...
Electromyography and mechanics of mastication in the albino rat
Tập 146 Số 1 - Trang 1-33 - 1975
AbstractThe masticatory apparatus in the albino rat was studied by means of
electromyography and subsequent estimation of muscular forces.The activity
patterns of the trigeminal and suprahyoid musculature and the mandibular
movements were recorded simultaneously during feeding. The relative forces of
the individual muscles in the different stages of chewing cycles and biting were
estimated on the ...
Physiology of feeding in miniature pigs
Tập 141 Số 4 - Trang 427-460 - 1973
AbstractThe anatomy and physiology of feeding in miniature swine were studied,
using gross dissection, electromyography, cinematography, and
cineradiography.Small particles are preferred for ingestion, and large items are
usually broken down outside of the oral cavity. The particles are initially
picked up with the lower lip and then retrieved by the tongue; the tongue very
rarely leaves the oral ...
Differential scaling of the long bones in the terrestrial carnivora and other mammals
Tập 204 Số 2 - Trang 157-169 - 1990
AbstractWe measured the lengths and diameters of four long bones from 118
terrestrial carnivoran species using museum specimens. Though intrafamilial
regressions scaled linearly, nearly all intraordinal regressions scaled
non‐linearly. The observed non‐linear scaling of bone dimensions within this
order results from a systematic decrease in intrafamilial allometric slope with
increasing body size....
The normal developmental stages of the zebrafish, brachydanio rerio (hamilton‐buchanan)

Vertebral column and associated elements in dipnoans and comparison with other fishes: Development and homology
Tập 250 Số 2 - Trang 101-172 - 2001
AbstractA vertebral column consisting of a persistent notochord and ossified
arcocentra is the primitive condition for Gnathostomata; it still persists in
primitive actinopterygians and sarcopterygians. Advanced actinopterygians and
sarcopterygians develop numerous types of centra that include, among others, the
presence of holocentrum, chordacentrum, and autocentrum. The chordacentrum, a
minerali...
