1. The branches of the optic nerve (N. ophthalmicus) (Fig. 523A).
Tentorial branch (r. tentorII). Thin branch starts from receptors located in the lateral and top walls cavernous sinus. Branch included ocular nerve at its exit from the orbit.
Lacrimal nerve (n. lacrimalis). Form fibers in contact with the receptors lacrimal gland, skin and conjunctiva of the lateral angle of the eye. To connect tearful nerve parasympathetic fibers who left zygomatic nerve. These postganglionic fibers originated from the node to the pterygopalatine innervation of the secretory cells of the lacrimal gland.

International A workweek subsequently, we disoriented all desire of e'er acquiring to Cooktown, checkered out of the Decoration Cove, and boarded a trajectory to Darwin. We bounced into Darwin a brace of hours late done the outer strands of two shaver cyclones that were bumping on the northward seacoast, and acquired another renting car—a silken Toyota saloon that looked as if it could concealment the 932 Read more [...]
Left coronary artery of the heart (a. coronaria cordis sinistra) starts at the left aortic sinus, 2-3 mm above the free edges of the left semilunar valve. The initial part of left coronary artery is located between the pulmonary trunk and the left heart ear, surrounded by fatty tissue. Artery has a length of 5-18 mm, the diameter of 4-5 mm. It is divided into two branches: the anterior interventricular branch (G interventricularis anterior) and environmental (r. circumflexus) (Fig. 390). Anterior branch of the anterior longitudinal fissure reaches cut apex and anastomoses with the posterior Read more [...]
2. The branches of the maxillary nerve (N. maxillaris) (Fig. 524). Middle meningeal branch (r. meningeus medius) starts from the receptors of the dura mater of the middle cranial fossa and maxillary nerve joins a round hole about the sphenoid bone.

Abdominal aorta gives visceral, parietal, and terminal branches.
Visceral branches of the abdominal aorta
1. Celiac trunk (truncus celiacus), with a diameter of 9 mm, a length of 0.5 - 2 cm, moving away from the ventral aorta at the level of XII thoracic vertebra (Fig. 402). Under the base of the celiac trunk is top edge of the body of the pancreas, and on either side of it - the celiac plexus. For the parietal peritoneum celiac trunk divides into three arteries: the left gastric, common hepatic and splenic.

We have already learned how to work with the compass on the map are able to delay the segment and in accordance with the scale to find the length in meters. For example, from the site of our camp we have to go on the road for about a kilometer and turn on the trail that goes to the right. Start motion, and suddenly a few minutes walk to the right goes one, then another, then - crossing paths. It is immediately clear that the card is out of date, and new trails, so what is ours? And it is impossible to do without taking account of distance, because until our path about a kilometer. Typically, Read more [...]
1. Anterior gastric branches (rr. gastrici anteriores) consist of sensitive, sympathetic and parasympathetic fibers. Sensory fibers have receptors in the wall of the stomach and in the small curvature of the front part of the vagus trunk. Parasympathetic and sympathetic fibers come out of the front of the vagus trunk and on the lesser curvature of the stomach form Extrahepatic plexus branches which penetrate the thickness of the wall of the stomach, forming podseroznye, intermuscular and submucosal plexus.
2. Posterior gastric branches (rr. gastrici posteriores) consist of a sensitive, sympathetic Read more [...]
Top jaw (Maxilla) steam is divided into four parts (Fig. 52).52. Top jaw Right.

The body (corpus) in his column contains pneumatic sinus (sinus maxillaris), lined with mucous membrane. Like all other pneumatic sinus skull, it communicates with the nasal cavity (middle nasal passage) through the maxillary cleft (hiatus maxillaris). Read more [...]

External iliac Vienna
Outdoor iliac Vienna (V. iliaca externa), a steam room, located medial to the first external iliac artery, and then behind her. In the external iliac vein flow inferior epigastric Vienna (V. epigastrica inferior) and deep Vienna, surrounding the iliac bone (v. circuflexa ilium profunda). This Vienna collects blood from the abdominal wall and the inner surface of a large basin.
Internal iliac Vienna
Internal iliac Vienna (V. iliaca interna) is formed from the same veins that accompany the parietal and visceral arteries of the pelvis. Feature is that in the pelvis around Read more [...]
Lower extremity divided into superficial and deep.
Superficial veins lie in the subcutaneous tissue and formed from the merger of small veins of the foot and lower leg, which pass into the dorsal and plantar network. The largest are the large and small saphenous veins, who, with their branches easily can form varicose.
1. Small subcutaneous Vienna (V. saphena parva) originates from subcutaneous venous network on the lateral surface of the foot. Located on the lower leg lateral triceps tendon, and then goes to the center line under the skin of the back of the leg, taking small Read more [...]
Cerebral veins (vv. cerebri) are separated on the surface formed in the cerebral cortex, and deep, starting from the central regions of the cerebral hemispheres.

Small veins and the systemic circulation together in the final major collectors - the superior vena cava, the inferior vena cava and cardiac veins circle - coronal sinus arrest. All of the major veins empty into the right atrium of the heart.
Veins of the pulmonary circulation (pulmonary)
Pulmonary veins (vv. pulmonales) originate from the lung venules located in the interlobular connective tissue in the walls of the bronchi, then the tops of segments forming large segmental vein. These vein contain arterial blood. At the gate of each lung, they merge into two large trunk. Read more [...]
Eyelids, top and bottom (palpebrae superior et inferior), limiting its front and rear edges (limbus palpebrales anteriores et posteriores) eye slit (rima palpebrum). The mobility of the upper eyelid more than lower. Lowering of the upper eyelid at the expense of the muscle surrounding the eye socket (pars palpebralis m. Orbicularis oculi). A reduction of the muscle decreases the curvature of the arc of the upper eyelid, which is why it moves down. Eyelid lifts special muscles (m. levator palpebrae superioris). The basis of the century is a dense connective tissue, which is covered with a thin Read more [...]
Breech births can result spontaneously without any complications for the fetus and the mother. However, some of the steps are fraught with great danger to the fetus, and often to the mother (high standing buttocks above the entrance to the pelvis, delayed discharge of amniotic fluid, the possibility of cord prolapse, often occurring rear view, and so on).
As you know, butt easier, but less well than the fetal head, overcome difficulties during the passage through the birth canal. Therefore, even with bouts of intense amount of work performed during the passage of the presenting part, will not Read more [...]

Since birth in the personal presentation at the vast majority of cases end spontaneously, in such cases, the management of labor must always adhere to expectant management. Any delay in the active intervention can only lead to some undesirable complications.
But the issue of an operational manual for the personal previa can occur at any time of the birth, when the head will be at the entrance or in the pelvic cavity. When selecting a particular intervention should be the structure of the pelvis, with the state (alive or dead), and fruit size and other features of the case (the preservation of Read more [...]
