Oogenesis in Xenopus laevis (Daudin). I. Stages of oocyte development in laboratory maintained animalsAbstract Oogenesis 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 d... ... hiện toàn bộ

Stages of oocyte development in the zebrafish, Brachydanio rerioAbstract Oocyte 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... ... hiện toàn bộ

The histogenesis of cartilage and bone in the long bones of the embryonic fowlAbstract The 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, t... ... hiện toàn bộ

Skeletal indicators of locomotor adaptations in living and extinct rodentsAbstract Living 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 locomoto... ... hiện toàn bộ

Electromyography and mechanics of mastication in the albino ratAbstract The 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 o... ... hiện toàn bộ

Physiology of feeding in miniature pigsAbstract The 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 t... ... hiện toàn bộ

Differential scaling of the long bones in the terrestrial carnivora and other mammalsAbstract We 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... ... hiện toàn bộ

Vertebral column and associated elements in dipnoans and comparison with other fishes: Development and homologyAbstract A 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 autocentr... ... hiện toàn bộ
