Sensory Components of the Phrenic Nerve of the Cat

Summary By degeneration of the somatic motor and sympathetic fibers in the phrenic nerve, it has been shown histologically that this nerve contains myelinated sensory fibers of different sizes and unmyelinated ones. The ratio of unmyelinated to myelinated sensory fibers is relatively high in 2 of the 3 phrenic nerves studied as compared to that reported for a motor branch of the femoral nerve.

Measurement of glomerular filtration rate in the dog.

Conclusion Inulin, exogenous and endogenous creatinine, and ferrocyanide ion are all cleared at the same rate by the dog kidney, and probably exclusively by glomerular filtration

Regulation of Skin Temperatures after Lesions of Spinal Nerve Roots

Summary 1. Deafferentation of a cats forelimb does not lower the skin temperature of the footpad which may remain similar to the contralateral normally innervated one or may be warmer. 2. Deafferentation of a hindlimb may not affect the pad temperature, or it may be lowered or raised. 3. Any differences present in the fore-limbs or in the hindlimbs disappear after bilateral sympathectomy. 4. Section of the L6-L7 and S1-S2 ventral roots of a cat may not significantly affect the pad temperatures.
