Intracellular recordings have been made from walking-leg motor neurones of the crayfish, Pacifastacus leniusculus, in isolated preparations of the thoracic ganglia. Some motor neurones display slow depolarizations that can drive bursts of spikes and resemble 'plateau' potentials described in other invertebrate and vertebrate neurones. Evidence is presented which suggests that the potentials are...

On the basis of a digital analysis of radiograms it was checked if, and to what extent, the extended loading of one of the sides of the body of racehorses leads to differences in the microstructure of the spongy bone of the bilateral pastern bones of the thoracic limbs. The research material consisted of radiograms of the pastern bones of the right and left thoracic limbs of racehorses. On the ...

Superior mediastinum contains many important vessels and tubes, variation of one may affect the other. Left brachiocephalic vein crosses arch of the aorta and its branches superficially. Arch of the aorta from its convex superior aspect usually provides brachiocephalic, left common carotid and left subclavian artery from the right to left. Left subclavian artery continues as axillary artery and...

Osteoporosis is a significant secondary condition that occurs acutely after spinal cord injury (SCI). This article reports on a patient with motor incomplete SCI and asymmetric lower-limb bone loss as it correlates with lower-limb motor function and gait characteristics. A 32-year-old Caucasian male completed a comprehensive inpatient rehabilitation program, including 3 months of robotic body-w...

A cat was evaluated for an acute-onset of right pelvic limb paresis. Thoracic radiographs revealed normal cardiac size and tortuous pulmonary arteries. Abdominal ultrasound identified a heartworm (HW) extending from the caudal abdominal aorta into the right external iliac artery and right femoral artery. The cat was HW-antigen positive. Echocardiography revealed a HW within the right branch of ...

OBJECTIVES The relationship between thoracic spine dysfunction and painful shoulder pathologies is poorly understood. This study sought to determine the intra-rater reliability of a protocol aimed at assessing the active mobility of the thoracic spine in individuals with chronic rotator cuff pathology. METHODS Ten individuals (6 men and 4 women) with chronic rotator cuff pathology were recrui...
