Li and colleagues [ 68 ] elegantly demonstrated in an angular rat fracture model that innervation of CGRP-positive nerves is higher at the concave compared with the convex site of the fracture. Chen MY, Goldenberg IF, Milstein S, Buetikofer J, Almquist A, Lesser J, et al. Neurohormonal interactions and adaptations in congestive heart failure. The sympathetic nerve route. Axon of neuron after ganglion synapse, extends to target cell. Liu D, Jiang LS, Dai LY.
Sympathetic nervous system
Postganglionic efferent fibers from the ganglia travel to the heart and vasculature where they synapse at their target sites. Manipulation of this signaling pathway by gene therapy may be useful in treating cardiac arrhythmias. Dorland's Illustrated Medical Dictionary 32nd ed. If the patient is felt to be a poor candidate for transplantation, cardiac sympathetic denervation is recommended. These preganglionic fibers run with the third nerve into the orbit and pass to the ciliary ganglion where they terminate by forming synapses with sympathetic motor neurons whose axons, postganglionic fibers, proceed as the short ciliary nerves to the eyeball. This implied that GABA was being released from endogenous stores and was providing a protective action in the absence of bath application.

Afferent aortic nerve fibers with their pathways in cardiac sympathetic nerves. - PubMed - NCBI
Nevertheless, nerve fibers have been documented in the enthesis fibrocartilage of rabbit knee joint menisci Gao et al. The left ventricle, particularly the inferoposterior wall, is a principal location for these sensory receptors. These cervical ganglia go down the primitive carotid and in front of the large muscles of the neck. Sympathicotonia is a stimulated  condition of the sympathetic nervous system, marked by vascular spasm ,  elevated blood pressure ,  and goose bumps. In all cases, the axon enters the paravertebral ganglion at the level of its originating spinal nerve.
Afferent aortic nerve fibers with their pathways in cardiac sympathetic nerves.
Description: The thoracolumbar sympathetics are characterized by the presence of numerous ganglia which may be divided into two groups, central and collateral. The epineurium is a continuation of the dura mater that extends to the ends of the peripheral nerves. Phases 1 and 3 most likely reflect mechanical factors eg, intrathoracic pressure changes , whereas phases 2 and 4 are a consequence of sympathetic, vagal, and baroreflex interactions. These receptors exist throughout the vasculature of the body but are inhibited and counterbalanced by beta-2 adrenergic receptors stimulated by epinephrine release from the adrenal glands in the skeletal muscles, the heart, the lungs, and the brain during a sympathoadrenal response. The number of venules is, as a rule, slightly greater than the number of arterioles.
