“…In the carotid sinus wall, this type of axon swelling has been reported previously by Knoche and Schmitt [1964], Rees [1967 a. b] and Chiba [1972]. According to the classification of Burnstock and Iway ama [1971].…”

“…In the present paper, these terms are used as synonyms. The terminal or intercalated ex pansions possess a mesaxon and are embedded in the cytoplasm of a ramified structural specialised Schwann cell, referred to by Knoche amI Schmitt [1964] as ter minal cell. The pressoreceptors are either submerged into the surface of these cells or surrounded only by a thin cytoplasmic seam formed by cell processes.…”

In the rabbit, baroreceptive intercalated and terminal receptor segments of the sinus nerve extend in the border region of adventitia and media of the carotid sinus wall. These receptors measuring 600–6,500 nm harbour a great number of mitochondria. They are either round, ovoid or elongated. Round receptors are present over the whole area of the carotid sinus. Large receptors appear to be missing in the upper region, where only very elongated receptors are present, which are arranged in circular array in relation to the vascular axis. The baroreceptors are enveloped by special organelle-rich terminal cells of Schwann cell origin. The receptors have a special orientation in regard to the muscle-elastic system and to collagen. Receptors contain osmiophilic and laminated bodies, signs of degeneration and vesicles of different sizes. Many tubuli as well as glycogen granules are apparent. Some of these axoplasmatic changes appear to be related to metabolic processes (turnover) occurring in young and old animals.

“…By electron microscopy it was evident that the reaction products were The presumptive baroreceptors in the carotid sinuses of various animals have been studied by light (1,2,14,18) and electron microscopy (3,4,10,11,12,15). In general, such baroreceptors are located in the regions between the adventitia and the media in the internal carotid artery wall, and consist of axon terminals with intermittent enlargements along their courses and Schwann cells investing such axon terminals.…”
