Variations of the vertebrobasilar arterial complex are important with regard to their potential clinical impact. We present an unusual case of the vertebral artery, in which the left vertebral artery in its ascent in the neck through the transverse foramina passed posteriorly between the transverse processes of C3 and C4 and supplied the posterior muscles of the neck without continuing intracranially. Albeit speculatively, we hypothesise that the variation of the vertebral artery reported here was caused by degeneration of the proximal portion of the left postcostal longitudinal anastomosis (i.e. C1 and C2 intersegmental arteries) in the context of a persistent third cervical intersegmental artery. Our case is unique in that the left vertebral artery terminated extracranially. Knowledge of the variations of the vertebrobasilar arterial complex is important for surgeons operating at the skull base, craniocervical junction, and cervical region, and for clinicians interpreting the imaging of this region.

Variations of the intracranial venous sinuses are important to the surgeon during intraoperative procedures and to the clinician during imaging interpretation. We report a male cadaver found to have a rare venous sinus variation. In all likelihood, this sinus corresponded to the rarely reported accessory venous sinus of Hyrtl. The sinus was approximately 5 mm in width and traveled from the sphenoparietal sinus anteriorly to the veins, draining into the foramen spinosum (i.e. the middle meningeal veins) posteriorly. No other variations or obvious pathology were identified intracranially or extracranially. Knowledge of such a venous variation may be of use to the clinician.

An accessory middle cerebral artery is one variation of the intracranial vasculature that may be a source of misinterpretation by clinicians dealing with cerebrovascular diseases. We report a case of an elderly female found to have bilateral accessory middle cerebral arteries, who presented with the rupture of an aneurysm of the anterior part of the circle of Willis. Accessory middle cerebral arteries are rare anatomical findings and the bilateral occurrence is exceedingly rare. We believe this to be the first report of bilateral accessory middle cerebral arteries associated with an aneurysm of the anterior cerebral-anterior communicating arteries. The anatomical and clinical relevance of this variation is described.

Background: The aim of the study was to precisely describe and classify the infraorbital canal/groove (IOC/G) complex in dry human skulls and to evaluate the presence of asymmetry in the IOC/G complex. Materials and methods: Seventy orbits of 35 human skulls were investigated. The following distances were measured: the distance between the posterior and anterior margin of the infraorbital groove (S-C); the posterior margin of the infraorbital canal and the infraorbital foramen (C-IOF); and the total length of the infraorbital canal-groove complex (S-C-IOF). The symmetry of the contralateral measurements was analysed. Results: Three types of the IOC/G complex were distinguished: types I, II, III, whose respective incidences were 11.4%, 68.6%, 20.0%. The mean length of the infraorbital groove plus canal complex on the right and left with standard deviation were 27.78 ± 3.69 mm and 28.06 ± 3.37 mm, respectively. Conclusions: The results presented in this study may be particularly helpful for surgery in patients with blow-out fractures and different endoscopic and reconstructive procedures in the region of the inferior orbital wall. The type III IOC/G complex, according to our classification, seems the most likely to be exposed to trauma during surgical manipulations. (Folia Morphol 2013; 72, 4: 311–317)

The aim of this study was to investigate seed morphology and intra- and inter-population variation of seeds of Trollius europaeus L. and Trollius altissimus Crantz., two controversial species regarding their taxonomical position. We analyzed seed-coat microsculpture and some biometrical traits (length and width, width/length ratio, volume and projected perimeter). Seed sculpture did not differ between species, but seeds of T. altissimus were usually larger than seeds of T. europaeus. Although species differed significantly in seed morphology, it was possible to show the populations of both species that were similar regarding the analyzed seed traits. We noted a significant inter-population differentiation of seeds in both species with respect to seed-coat microornamentation and biometrical traits. We conclude that T. europaeus and T. altissimus are probably not two distinct species, but T. europaeus should be divided into two lower taxa in the rank of variety or subspecies.

The obturator foramen is a large opening in the hip bone situated below and anterior to the acetabulum. The obturator foramen is enclosed by the obturator membrane, apart from the part above near the obturator groove, where the obturator vessels and nerve pass through. The present study reports multiple openings in the obturator foramen detected incidentally in a left hip bone specimen and discusses its clinical implications. To the best of our knowledge, the occurrence of multiple openings associated with the obturator foramen is rare and has not been reported in any standard textbook of anatomy or in any research study. Anatomical knowledge of the presence of such anomalies may be clinically important for radiologists interpreting skiagrams and surgeons performing operative procedures in the hip region.

The biceps brachii muscle is present in the anterior aspect of the arm. Its morphological variations have great clinical significance for surgeons, orthopaedic surgeons, anaesthetists, neurologists and anatomists. This study aimed to describe the incidence and morphology of the extra-heads of the biceps brachii muscle. Hundred upper limbs of 50 adult human cadavers (30 men and 20 women) were used in this study after the approval of the medical ethical committee. These cadavers were obtained from the Anatomy Department, Faculty of Medicine, King Abdul-Aziz University. The incidence of anatomical variations of biceps muscle was equal in both male and female cadavers (10%) with predominance of the left side (7%). The 3-headed biceps brachii muscle was noticed in 7% (4% male and 3% female), while the 4-headed biceps was seen in 2 (2%) left limbs, 1 male and 1 female. The third head of the biceps muscle arose from the anteromedial aspect of humerus, between the coracobrachialis insertion and the brachialis origin, in 6% and from middle of the medial border of humerus in 3%. While the fourth head originated from the articular capsule of shoulder joint in 1 (1%) limb and from the coracoid process of scapula in the other limb. The biceps common tendon of insertion received the supernumerary heads in 7% of the limbs. However, the extra-head fused with the long head in 2 (2%) limbs and united with the short head in 1 (1%) limb. The mean of the third head length was 118.8 ± 10.9 in all limbs, where it was 121.8 ± 12.3 in male and 113.5 ± 8.1 in female cadavers. The third head length/arm length ratio was 38.4 ± 2.6 in all, 38.3 ± 3.4 in male and 38.8 ± 1.8 in female cadavers. The length of the extra-head was extremely significant with those of the corresponding limb in all, male and female cadavers (p < 0.0001). Knowledge of the morphological variations of biceps muscle provides better pre-operative evaluation, safe surgical intervention within the arm and better postoperative outcomes.

Variations of the inferior alveolar artery are seemingly quite rare, especially with regard to its origin from the maxillary artery. We present an unusual case of an inferior alveolar artery that originated from the external carotid artery. To the best of our knowledge, our case is one of only two reports of the inferior alveolar artery arising from the external carotid artery. The clinician who deals with the mandibular region should be aware of such a variation in the arterial architecture.

The sternalis muscle variation is a well-known anatomical situation. It is present in 8.7% of women and 6.4% of men, although the incidence varies according to sex, race and ethnicity. During a left modified radical mastectomy operation on a 46-year-old female patient a sternalis muscle was detected on the pectoralis major muscle in the superficial fascia. It was in craniocaudal position and was parallel to the body of the sternum. The cylindrical muscle was approximately 8 cm in length and 2 cm in diameter. Such variations are considered to have their origin in embryological development. Awareness of muscular variations and their identification is important both for procedure through the proper dissection planes during breast surgery and in radiological examination and follow-up.

During routine dissections carried out in the course of our medical gross anatomy work, an unusual structure was found unilaterally on the left side of an adult male cadaver. Upon investigation, this was determined to be a hugely dilated transverse facial artery. Also noted was the complete absence of the ipsilateral facial artery. To our knowledge, this is the first report of complete agenesis and not simply diminution of the facial artery with compensatory enlargement of the transverse facial artery.
