Development of the arterial pattern in the upper limb of staged human embryos: normal development and anatomic variations
J Anat. 2001 Oct;199(Pt 4):407-17.
Rodríguez-Niedenführ M1, Burton GJ, Deu J, Sañudo JR.
A total of 112 human embryos (224 upper limbs) between stages 12 and 23 of development were examined. It was observed that formation of the arterial system in the upper limb takes place as a dual process. An initial capillary plexus appears from the dorsal aorta during stage 12 and develops at the same rate as the limb. At stage 13, the capillary plexus begins a maturation process involving the enlargement and differentiation of selected parts. This remodelling process starts in the aorta and continues in a proximal to distal sequence. By stage 15 the differentiation has reached the subclavian and axillary arteries, by stage 17 it has reached the brachial artery as far as the elbow, by stage 18 it has reached the forearm arteries except for the distal part of the radial, and finally by stage 21 the whole arterial pattern is present in its definitive morphology. This differentiation process parallels the development of the skeletal system chronologically. A number of arterial variations were observed, and classified as follows: superficial brachial (7.7%), accessory brachial (0.6%). brachioradial (14%), superficial brachioulnar (4.7%), superficial brachioulnoradial (0.7%), palmar pattern of the median (18.7%) and superficial brachiomedian (0.7%) arteries. They were observed in embryos belonging to stages 17-23 and were not related to a specific stage of development. Statistical comparison with the rates of variations reported in adults did not show significant differences. It is suggested that the variations arise through the persistence, enlargement and differentiation of parts of the initial network which would normally remain as capillaries or even regress.
A total of 112 serially sectioned human embryos (224 upper limbs) belonging to the Bellaterra Collection (Prof. J. M. Domenech. Unidad de Anatomy a y Embriologı!a Humana, Universidad Auto!noma de Barcelona, Spain) and the Boyd Collection (Department of Anatomy, University of Cambridge, UK) were studied.
Variations of the arterial pattern in the upper limb revisited: a morphological and statistical study, with a review of the literature
J Anat. 2001 Nov;199(Pt 5):547-66.
Rodríguez-Niedenführ M1, Vázquez T, Nearn L, Ferreira B, Parkin I, Sañudo JR.
A total of 192 embalmed cadavers were examined in order to present a detailed study of arterial variations in the upper limb and a meta-analysis of them. The variable terminology previously used was unified into a homogenous and complete classification, with 12 categories covering all the previously reported variant patterns of the arm and forearm.
Association of tracheoesophageal anomalies with visceral and parietal malformations in a human embryo (Carnegie stage 21)
Teratology. 1989 Jan;39(1):11-7.
Nebot-Cegarra J1, Domenech-Mateu JM.
A human embryo (Carnegie stage 21) with tracheoesophageal malformations (esophageal atresia and tracheoesophageal fistula) and anomalies at the caudal end of the embryo (anorectal atresia, rectovesical fistula, vertebral and notochordal defects, and agenesis of the metanephros) was studied. Other anomalies observed were: absence of right umbilical artery, fusion of spinal ganglia, and absence of cloacal outlet of mesonephric ducts. The possible pathogenesis of these associated malformations is discussed. PMID 2718136
Development and arterial supply of the supraventricular crest during the human embryonic and fetal periods
Acta Anat (Basel). 1988;132(2):143-9.
Several works have concerned themselves with the anatomy of the supraventricular crest, for example, analyzing its role in the physiology of the right ventricle; nevertheless, its structure and arterial supply have been less studied. We have studied the morphogenesis of the architecture and the arterial supply of the supraventricular crest, in 25 embryos and human fetuses of 13-71 mm crown-rump length. The muscular organization of the crest (proper muscular bundles and parietal bundles of the right ventricle) and the development of the supraventricular crest's artery as well as its trajectory and its distribution during the fetal period were examined.

Development and arrangement of the tympanic plexus and the nerve of the pterygoid canal during the human embryonic and fetal periods
Acta Morphol Neerl Scand. 1980 Aug;18(3):253-72.
Domenech Mateu JM, Pueyo Mur FJ.
The constitutional pattern of the n. canalis pterygoidei and the tympanic plexus was studied in a human embryo (SAM 30 mm) and human fetuses (39-71 mm) which were stained according to the Bielschowsky technique. Reconstructions according to the Born technique were made of the fetuses ED and FRA-3. The following was observed during the fetal and embryonic period in the development of the n. canalis pterygoidei: (1) the n. petrosus superficialis major is always a branch of the n. facialis; (2) the n. petrosus profundus major is during the fetal period always a branch of the n. tympanicus and is of considerable diameter; (3) the contribution of the sympathetic branch of the plexus caroticus; (4) an anastomotic branch with the tympanic plexus; (5) the n. sphenoidalis is observed passing from the otic ganglion to the n. canalis pterygoidei during the end stages of the embryonic period (SAM 30 mm). The fibers of this nerve arise from the microganglion which is a detachment from the medial portion of the otic ganglion. Also the following was observed: the anastomosis of the tympanic plexus with the auricular branch of the vagus nerve (Figs. 3(AV) and 4(Av)) and ganglionic accumulations found in relation with these nerves (Figs. 2, 3, 5, 6, 8, 9, 11, 14, 17 and 18).

J Anat. 1979 Mar;128(Pt 2):365-75. Innervation of the sinu-atrial node and neighbouring regions in two human embryos. Orts Llorca F, Domenech Mateu JM, Puerta Fonolla J. Abstract In human embryos of 20 to 23 mm (36 to 40 days) it is possible to identify on the right side a nerve that we may call the sinusal, which originates by several roots from the nervus vagus dexter (Figs. 1A, B, D), descending through the right ventrolateral face of the primary trachea and right bronchus (Fig. 2, arrows). Beaded in appearance, it gives a fine anastomotic branch which, passing in front of the arteria pulmonalis dextra, passes to the left side (Figs. 2B, C, D; AN). At this level it gives the large branch for the nodus sinoatrialis which, penetrating through the wall of the superior vena cava, provides a rich innervation for the nodus sinoatrialis which is already in an advanced stage of differentiation (Fig. 3, 2; Cy, D, AN). Afterwards it gives fine branches which, following the atrial fold, are distributed throughout the posterior face of the atrium dextrum (Fig. 3). It increases in diameter and, passing through the angle formed by the right pulmonary veins with the atrium dextrum, reaches the intrapericardial portion of the inferior vena cava in the vicinity of its outlet from the atrium (Fig. 3, arrows). The whole innervation is parasympathetic at the stages studied. PMID 438095
