Development of vagal innervation to the muscle of the avian gizzard

Journal of the Autonomic Nervous System, 1993
The development of the vagal innervation to the gizzard has been investigated in chick embryos and young chicks. The membrane potential, first measurable on the 15th day of incubation, was -54 +/- 0.5 mV and increased with development to -67 +/- 0.4 mV. The latter value was attained 5 days after hatching and persisted thereafter.

Gizzard myoglobin contents and feeding habits in avian species

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2000
In an attempt to consider physiological function of myoglobin (Mb), we determined Mb contents of gizzard smooth muscles with special reference to feeding habits in 85 avian species of 19 orders. The Mb content in 44 species of herbivorous birds was 7.52+/-3.81 mg/g wet muscle, which was significantly higher than the value of 2.34+/-1.74 mg/g in 41 ...

Studies on the avian gizzard: Morphology and innervation of the smooth muscle

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1969
Light and electron-microscope studies of the smooth muscle of the gizzard and its innervation in the chick and the pigeon have been made. The muscle is organised into extensive interlocking bundles, with frequent anastomoses between adjacent bundles. Nexuses are common between apposing smooth muscle cell membranes.

Gizzard Erosion in Broiler Chicks by Group I Avian Adenovirus

Avian Diseases, 2001
Incidences of mortality without any clinical signs occurred in growing chicks in a broiler flock. Five 17-day-old dead broilers with gizzard erosions were investigated pathologically. Macroscopically, the gizzards were found to be dilated with bloody fluids. The koilin layer of the gizzards showed multifocal black patches (erosions).

Ectonucleotidases of Avian Gizzard Smooth Muscle and Liver Plasma Membranes: A Comparative Study

Archives of Biochemistry and Biophysics, 1999
Extracellular nucleotides, e.g., ATP, ADP, and UTP, are important signaling molecules which elicit various physiological responses in different tissues. Their degradation is catalyzed by ectonucleotidases which are located on cell surfaces. Most tissues have a mixed population of ectonucleotidases.

Is glycogen a major energy source in avian gizzard smooth muscle contraction?

Experientia, 1990
In comparison to other avian smooth and striated muscles, chicken gizzard contains very low levels of glycogen. This myoglobin-rich muscle seems to derive the energy for its powerful contraction from other sources.

Unique geometry of actin-membrane anchorage sites in avian gizzard smooth muscle cells

Journal of Cell Science, 1989
ABSTRACT Adherens junctions in isolated avian gizzard smooth muscle cells appear as short longitudinal streaks or chevrons that are arranged in periodic, mainly transverse bands along the cell surface. This barrel-like geometry, revealed by antibodies to either vinculin or talin, was seen also in teased gizzard strips by confocal laser ...

Studies on the avian gizzard: Histochemical analysis of the extrinsic and intrinsic innervation

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1969
The innervations of the gizzards of the chick and pigeon have been examined using histochemical methods for the localisation of catecholamines and cholinesterases. The perivascular sympathetic nerve trunks of both species contain cholinergic and noradrenergic fibres.

Wide Variation of Myoglobin Contents in Gizzard Smooth Muscles of Various Avian Species

1988
We determined myoglobin contents of gizzards (muscular stomach) and breast muscles in 34 avian species by a modification of Reynafarje's spectrophotometric procedure. The birds were apparently differentiated into two groups in respect of the gizzard, one with a high myoglobin content (7.74 +/- 1.81 mg/g muscle) and the other with a low (1.54 +/- 0.41 ...
