Innervation of the molar gland and blood vessels in the lower lip, gingiva and cheek mucous membrane was investigated in the cat with the aid of whole mount acetylthiocholinesterase (WATChE) histochemistry and retrograde neuronal tracing methods with horseradish peroxidase (HRP) and HRP-conjugated wheat germ agglutinin (WGA-HRP). The molar gland was found to be supplied from the buccal nerve an...

In 2014, a published study based on dissections and skeletal examinations noted that 19:50 Thoroughbred horses had a congenital malformation of the 6th cervical vertebra (C6). In addition, it was found that in those 19 Thoroughbred horses expressing a congenital malformation of C6, 9 displayed a concurrent congenital malformation of the 7th cervical vertebra (C7). In this study, 3 Thoroughbred ...

In both non-immune and immune mice infected with herpes simplex virus the incidence of latent infection of the trigeminal ganglion was related to the severity of ocular virus infection. During primary infection, virus was shown to travel via the ophthalmic part of the ganglion to reach the brainstem, from where centrifugal spread resulted in latent infection of neurones in the trigeminal gangli...

The effect on the ear of stimulating the sympathetic nervous system was studied in rats by recording the compound action potentials (N1N2) in response to 2 kHz tonebursts presented to anesthetized rats before, during, and after electrical stimulation of the superior cervical ganglion, and evaluating the changes in N1 latency which resulted. Stimulation of the superior cervical ganglion was foun...

Hypertension is associated with enhanced cardiac sympathetic transmission, although the exact mechanisms underlying this are still unknown. We hypothesized that defective function of the norepinephrine uptake transporter (NET) may contribute to the sympathetic phenotype of the spontaneously hypertensive rat, and that this may occur before the development of hypertension itself. The dynamic kine...

THE MINIMAL duration of the synaptic delay of ocular motoneurons has been determined (1935a) with sufficient accuracy, but considerable dificulties have been found in measuring its maximal duration. Experimental results (1935d) indicated that the maximal delay is not much longer than the minimal delay, and that the expected small variations could scarcely be measured in the original preparation...

Interactions between nicotinic excitatory postsynaptic potentials (EPSPs) critically determine whether paravertebral sympathetic ganglia behave as simple synaptic relays or as integrative centers that amplify preganglionic activity. Synaptic connectivity in this system is characterized by an n + 1 pattern of convergence, where each ganglion cell receives one very strong primary input and a vari...

THI lacrimal gland is innervated by the lacrimal, the facial, and the cervical sympathetic nerves; the anatomical and functional characteristics of each were briefly summarized in a previous communication (Whitwell, 1958). Overwhelming evidence points to the fact that the lacrimal nerve is not secretory in function, but is purely the afferent path ofa reflex arc. Similarly, the facial nerve is ...
