The avian lumbosacral vertebral column and spinal cord show a number of specializations which have recently been interpreted as a sense organ of equilibrium. This sense organ is thought to support balanced walking on the ground. Although most of the peculiar structures have been described previously, there was a need to reevaluate the specializations with regard to the possible function as a sense organ. Specializations were studied in detail in the adult pigeon. The development of the system… Expand

Specializations in the lumbosacral vertebral canal and spinal cord of birds: evidence of a function as a sense organ which is involved in the control of walking
  • R. Necker
  • Biology, Medicine
  • Journal of Comparative Physiology A
  • 2006
TLDR
Birds have two nearly independent kinds of locomotion and it is suggested that two different sense organs play an important role in their respective control: the vestibular organ during flight and the lumbosacral system during walking. Expand
The balance hypothesis for the avian lumbosacral organ and an exploration of its morphological variation
TLDR
It is found that birds that perch tend to have more prominent transverse canals, suggesting that the LSO is useful for balance-intensive behaviors, and some key questions need to be asked to advance the understanding of this fascinating and mysterious part of the bird spinal cord. Expand
The Balance Hypothesis for the Avian Lumbosacral Organ and an Exploration of Its Morphological Variation
TLDR
It is found that birds that perch tend to have more prominent transverse canals, suggesting that the LSO is useful for balance-intensive behaviors, and the crucial outstanding questions about LSO structure and function are identified. Expand
3D Anatomy of the Quail Lumbosacral Spinal Canal—Implications for Putative Mechanosensory Function
TLDR
3D anatomy of the lumbosacral region of the common quail is quantified, focusing on establishing the geometric and biomechanical properties relevant to potential mechanosensing functions, and the structure of the LSO is reminiscent of a mass-spring-based accelerometer. Expand
Structural Insights of the Glycogen Body in Domestic Chicken
TLDR
The results revealed that the glycogen body is a very delicate, small, ovoid circumventricular, transparent and gelatinous consistency structure embedded in the dorsal part of the lumbosacral region of spinal cord. Expand
Synsacra of the Eocene Antarctic penguins : new data on spinal maturation and an insight into their role in the control of walking
The synsacrum is an important element of the axial skeleton in birds, both volant and flightless. Little is known about the maturation of this complex bone in penguins. In this work, the supposedly… Expand
Development and evaluation of a technique for spinal anaesthesia in broiler chickens
ABSTRACT Aims To develop a technique for the injection of local anaesthetic into the spinal canal of broiler chickens by first determining the ideal location for needle placement based on anatomy and… Expand
Chick spinal accessory lobes contain functional neurons expressing voltagegated sodium channels generating action potentials.
TLDR
Results clearly indicate that functional neurons expressing fast inactivating and TTXsensitive VGSC which generate action potentials exist in the AL of the chick and further support the proposal that the chick ALs function as the sensory organ of equilibrium. Expand
Natural loss of function of ephrin-B3 shapes spinal flight circuitry in birds
TLDR
A role for loss of ephrin-B3 function in shaping the avian brachial spinal cord circuitry and facilitating synchronous wing flapping is supported. Expand

TLDR
In the present investigation additional morphological specializations are described for the pigeon, which consist of segmentally organized semicircular canal-like structures which together with specializations in the meninges of the spinal Cord form a large liquor space above accessory lobes attached to the spinal cord. Expand
Ultrastructural characterization of the accessory lobes of Lachi in the lumbosacral spinal cord of the pigeon with special reference to intrinsic mechanoreceptors
TLDR
A complete analysis of the structural basis of segmentally organized accessory lobes in the lumbosacral spinal cord of birds was performed by means of electron microscopy, finding that Glycogen cells and lacunae may contribute to transmission of hydrostatic pressure changes during movements of the body. Expand
Specializations within the lumbosacral spinal cord of the pigeon
TLDR
The fine structure of the accessory lobes of Lachi in pigeons and their interaction with ligaments for features which might support such a mechanoreceptive function are examined. Expand
Behavioral evidence of the role of lumbosacral anatomical specializations in pigeons in maintaining balance during terrestrial locomotion
TLDR
Results support the assumption that the lumbosacral specializations are involved in the control of locomotion on the ground, and the effect of opening the fluid space was studied in pigeons. Expand
Development of the Glycogen Body of the Chick Spinal Cord. II. Effects of Unilateral and Bilateral Leg-Bud Extirpation
THE normal morphogenesis, vasculogenesis, and anatomical relationships of the "glycogen body" of the chick spinal cord have recently been described in detail by Watterson (1949). This unusual… Expand
Development of an Identified Spinal Commissural Interneuron Population in an Amniote: Neurons of the Avian Hofmann Nuclei
TLDR
HN neurons are determined to be commissural interneurons before attaining their definitive locations and their longitudinal axons attain mature extent in the ventral funiculus of the contralateral side and begin to sprout collaterals. Expand
On the sinus lumbosacralis, spina bifida occulta, and status dysraphicus in birds
The sinus rhomboidalis sacralis or sinus lumbosacralis as it is named by Ariens Kappers (1920) is an interesting anatomical part of the lumbosacral region of the avian spinal medulla. It is found in… Expand

TLDR
Extracellular electrophysiological recordings were done during vibratory stimuli applied to the whole body of anesthetized pigeons and strongly supports a mechanosensitive function of the lobe neurons. Expand
Embryonic growth and trophotaenial development in goodeid fishes (Teleostei: Atheriniformes)
TLDR
Embryonic growth and trophotaenial development are examined in two species of goodeid fish, Ameca splendens and Goodea atripinnis, and differ in the degree of axial elongation during the fifth and final phase. Expand

TLDR
A striking modification of Mallory's connective tissue stain is devised by replacing fuchsin with a stable and exclusively nudear stain (Kernechtrot) which is a very brilliant carmine. Expand
