Motor Nerve Terminal Morphology with Unloading and Reloading of Muscle in Procambarus Clarkii
Skeletal muscle shows dynamic changes in mass that correlate with activity and weight bearing loads. The electrical excitation of the muscle of Procambarus clarkii (Girard, 1952) used in this study is graded which requires refined nerve-muscle matching in synaptic efficacy. We used the anterior levator (a.l.) muscle in crayfish as a model to address matching of the extent of nerve terminal and ...
متن کاملNo change in myonuclear number during muscle unloading and reloading.
Muscle fibers are the cells in the body with the largest volume, and they have multiple nuclei serving different domains of cytoplasm. A large body of previous literature has suggested that atrophy induced by hindlimb suspension leads to a loss of "excessive" myonuclei by apoptosis. We demonstrate here that atrophy induced by hindlimb suspension does not lead to loss of myonuclei despite a stro...
متن کاملSpermiogenesis in the Crayfish (procambarus Clarkii)
The sperm of the crayfish, Procambarus clarkii, is relatively simple among decapod sperm and was described in the first paper of this series (28). The present paper details the development of this sperm as followed with the light and electron microscopes. The process is divided into six stages for purposes of description. The main points of interest discussed are the absence of mitochondria or ...
متن کاملOnion powder as feed additive in Procambarus clarkii culture
120 days trial was performed to evaluate the effect of dietary onion powder on the growth performance of red swamp crayfish Procambarus clarkii. Crayfish with initial body weight of 1.37±0.13 g were randomly stocked to experimental tanks. Four different onion powder levels in ratios of 10, 20, 30, and 40 g/kg were added to the formulated experimental basal feed and a control group was fed with ...
متن کاملUnloading of juvenile muscle results in a reduced muscle size 9 wk after reloading.
The role of satellite cells and DNA unit size in determining muscle size was examined by inhibiting postnatal skeletal muscle development by using hindlimb suspension. Satellite cell mitotic activity and DNA unit size were determined in the soleus muscles from hindlimb-suspended and age-matched weight-bearing rats before the initiation of hindlimb suspension, at the conclusion of a 28-day hindl...
