The Facial Artery of the Dog
Oka jimas Folia Anat. Jpn., 57(1) : 55-78, May 1980 The Facial Artery of the Dog By MOTOTSUNA IRIFUNE Department of Anatomy, Osaka Dental University, Osaka (Director: Prof. Y. Ohta) (with one textfigure and thirty-one figures in five plates) -Received for Publication, November 10, 1979- Key words: Facial artery, Dog, Plastic injection, Floor of the mouth. Summary. The course, branching and distribution territories of the facial artery of the dog were studied by the acryl plastic injection method. In general, the facial artery was found to arise from the external carotid between the points of origin of the lingual and posterior auricular arteries. It ran anteriorly above the digastric muscle and gave rise to the styloglossal, the submandibular glandular and the ptery- goid branches. The artery continued anterolaterally giving off the digastric, the inferior masseteric and the cutaneous branches. It came to the face after sending off the submental artery, which passed anteromedially, giving off the digastric and mylohyoid branches, on the medial surface of the mandible, and gave rise to the sublingual artery. The gingival, the genioglossal and sublingual plical branches arose from the vessel, while the submental artery gave off the geniohyoid branches. Posterior to the mandibular symphysis, various communications termed the sublingual arterial loop, were formed between the submental and the sublingual of both sides. They could be grouped into ten types. In the face, the facial artery gave rise to the mandibular marginal, the anterior masseteric, the inferior labial and the buccal branches, as well as the branch to the superior, and turned to the superior labial artery. -
Blood Vessels
BLOOD VESSELS Blood vessels are how blood travels through the body. Whole blood is a fluid made up of red blood cells (erythrocytes), white blood cells (leukocytes), platelets (thrombocytes), and plasma. It supplies the body with oxygen. SUPERIOR AORTA (AORTIC ARCH) VEINS & VENA CAVA ARTERIES There are two basic types of blood vessels: veins and arteries. Veins carry blood back to the heart and arteries carry blood from the heart out to the rest of the body. Factoid! The smallest blood vessel is five micrometers wide. To put into perspective how small that is, a strand of hair is 17 micrometers wide! 2 BASIC (ARTERY) BLOOD VESSEL TUNICA EXTERNA TUNICA MEDIA (ELASTIC MEMBRANE) STRUCTURE TUNICA MEDIA (SMOOTH MUSCLE) Blood vessels have walls composed of TUNICA INTIMA three layers. (SUBENDOTHELIAL LAYER) The tunica externa is the outermost layer, primarily composed of stretchy collagen fibers. It also contains nerves. The tunica media is the middle layer. It contains smooth muscle and elastic fiber. TUNICA INTIMA (ELASTIC The tunica intima is the innermost layer. MEMBRANE) It contains endothelial cells, which TUNICA INTIMA manage substances passing in and out (ENDOTHELIUM) of the bloodstream. 3 VEINS Blood carries CO2 and waste into venules (super tiny veins). The venules empty into larger veins and these eventually empty into the heart. The walls of veins are not as thick as those of arteries. Some veins have flaps of tissue called valves in order to prevent backflow. Factoid! Valves are found mainly in veins of the limbs where gravity and blood pressure VALVE combine to make venous return more 4 difficult. -

It directly attaches to the cranial bones (is incorporated into periosteal layer of dura mater), favors common injuries in course of head trauma. This review describes available data on the MMA considering its varability, or treats specific diseases or injuries where the course of MMA may have clinical impact. Key words: Middle meningeal artery (MMA), aneurysm of the middle meningeal artery, epidural he- matoma, anatomical variation of MMA. TOPOGRAPHY OF THE MIDDLE MENINGEAL ARTERY AND ITS BRANCHES Middle meningeal artery (MMA) [1] is most commonly the strongest branch of maxillary artery (from external carotid artery) [2]. It supplies blood to cranial dura mater, and through the numerous perforating branches it nourishes also periosteum of the inner aspect of cranial bones. It enters the middle cranial fossa through the foramen spinosum, and courses between the dura mater and the inner aspect of the vault of the skull. Next it divides into two terminal branches — frontal (anterior) which supplies blood to bones forming anterior cranial fossa and the anterior part of the middle cranial fossa; parietal branch (posterior), which runs more horizontally toward the back and supplies posterior part of the middle cranial fossa and supratentorial part of the posterior cranial fossa. -
Fetal Descending Aorta/Umbilical Artery Flow Velocity Ratio in Normal Pregnancy at 36-40 Weeks of Gestational Age Riyadh W Alessawi1
American Journal of BioMedicine AJBM 2015; 3(10):674 - 685 doi:10.18081/2333-5106/015-10/674-685 Fetal descending aorta/umbilical artery flow velocity ratio in normal pregnancy at 36-40 Weeks of gestational age Riyadh W Alessawi1 Abstract Doppler velocimetry studies of placental and aortic circulation have gained a wide popularity as it can provide important information regarding fetal well-being and could be used to identify fetuses at risk of morbidity and mortality, thus providing an opportunity to improve fetal outcomes. Prospective longitudinal study conducted through the period from September 2011–July 2012, 125 women with normal pregnancy and uncomplicated fetal outcomes were recruited and subjected to Doppler velocimetry at different gestational ages, from 36 to 40 weeks. Of those, 15 women did not fulfill the protocol inclusion criteria and were not included. In the remaining 110 participants a follow up study of Fetal Doppler velocimetry of Ao and UA was performed at 36 – 40 weeks of gestation. Ao/UA RI: 1.48±0.26, 1.33±0.25, 1.37± 0.20, 1.28±0.07 and 1.39±0.45 respectively and the 95% confidence interval of the mean for five weeks 1.13-1.63. Ao/UA PI: 2.83±2.6, 1.94±0.82, 2.08±0.53, 1.81± 0.12 and 3.28±2.24 respectively. Ao/UA S/D: 2.14±0.72, 2.15±1.14, 1.75±0.61, 2.52±0.18 and 2.26±0.95. The data concluded that a nomogram of descending aorto-placental ratio Ao/UA, S/D, PI and RI of Iraqi obstetric population was established. -

Notably the Posterior Cerebral Artery, Do Not Develop Fully Until the Embryo
THE EMBRYOLOGY OF THE ARTERIES OF THE BRAIN Arris and Gale Lecture delivered at the Royal College of Surgeons of England on 27th February 1962 by D. B. Moffat, M.D., F.R.C.S. Senior Lecturer in Anatomy, University College, Cardiff A LITTLE OVER 300 years ago, Edward Arris donated to the Company of Barbers and Surgeons a sum of money " upon condicion that a humane Body be once in every yeare hearafter publiquely dissected and six lectures thereupon read in this Hall if it may be had with conveniency, and the Charges to be borne by this Company ". Some years later, Dr. Gale left an annuity to the Company for a similar purpose and it is interesting to note that the first Gale lecturer was a Dr. Havers, whose name is still associated with the Haversian canals in bone. The study of anatomy has changed in many ways since those days and it must be a long time since an Arris and Gale lecturer actually took his text from the cadaver. However, in deference to the wishes of our benefactors, I should like at least to com- mence this lecture by showing you part of a dissection (Fig. 1) which a colleague, Dr. E. D. Morris, and I prepared some years ago for use in an oral examination. We found that in this subject the left internal carotid artery in the neck gave off a. large branch which passed upwards and back- wards to enter the skull through the hypoglossal canal. In the posterior cranial fossa this artery looped caudally and then passed forwards in the midline to form the basilar artery which was joined by a pair of very small vertebral arteries. -

Surgical Anatomy of the Common Iliac Veins During Para-Aortic and Pelvic Lymphadenectomy for Gynecologic Cancer
Original Article J Gynecol Oncol Vol. 25, No. 1:64-69 http://dx.doi.org/10.3802/jgo.2014.25.1.64 pISSN 2005-0380·eISSN 2005-0399 Surgical anatomy of the common iliac veins during para-aortic and pelvic lymphadenectomy for gynecologic cancer Kazuyoshi Kato, Shinichi Tate, Kyoko Nishikimi, Makio Shozu Department of Gynecology, Chiba University School of Medicine, Chiba, Japan See accompanying editorial by Lee on page 1. Objective: Compression of the left common iliac vein between the right common iliac artery and the vertebrae is known to be associated with the occurrence of left iliofemoral deep vein thrombosis (DVT). In this study, we described the variability in vascular anatomy of the common iliac veins and evaluated the relationship between the degree of iliac vein compression and the presence of DVT using the data from surgeries for gynecologic cancer. Methods: The anatomical variations and the degrees of iliac vein compression were determined in 119 patients who underwent systematic para-aortic and pelvic lymphadenectomy during surgery for primary gynecologic cancer. Their medical records were reviewed with respect to patient-, disease-, and surgery-related data. Results: The degrees of common iliac vein compression were classified into three grades: grade A (n=28, 23.5%), with a calculated percentage of 0%-25% compression; grade B (n=47, 39.5%), with a calculated percentage of 26%-50% compression; and grade C (n=44, 37%), with a calculated percentage of more than 50% compression. Seven patients (5.9%) had common iliac veins with anomalous anatomies; three were divided into small caliber vessels, two with a flattened structure, and two had double inferior vena cavae.
