3b. 5. The Sinuses of the Dura Mater (2) A parietal emissary vein passes through the parietal foramen and connects the superior sagittal sinus with the veins of the scalp. (3) A net-work of minute veins (rete canalis hypoglossi) traverses the hypoglossal canal and joins the transverse sinus with the vertebral vein and deep veins of the neck.8) An internal carotid plexus of veins traverses the carotid canal and unites the cavernous sinus with the internal jugular vein. (9) A vein is transmitted through the foramen cecum and connects the superior sagittal sinus with the veins of the nasal cavity.

Introduction to Cranial Nerves Reproduced with permission. The fluid flows through the interventricular foramen (of Monro) into the third ventricle, is augmented by fluid formed by the choroid plexus of this ventricle, and passes through the cerebral aqueduct (of Sylvius) to the fourth ventricle, which also possesses a choroid plexus.

patent abnormal persistence of an open lumen in the ductus arteriosus, between the aorta and the pulmonary artery, after birth. The ductus arteriosus is open during prenatal life, allowing most of the blood of the fetus to bypass the lungs, but normally this channel closes shortly before birth. When the ductus arteriosus remains open, it places special burdens on the left ventricle and causes a diminished blood flow in the aorta.

- Before labor, this mucus plug is expelled allowing the baby to pass through the cervix during labor and birth. How soon after my mucus plug passes will labor begin? Passing a mucus plug is a sign that your cervix is dilating and that your body is preparing for birth. Labor could be hours, days, or even weeks away as the cervix gradually opens.

Convenia Long-Acting Antibiotic Injection Patent Foramen Ovale Closure with the AMPLATZER™ PFO Occluder . Information Guide for Patients and Caregivers . This guide is for patients who have previously suffered a stroke that was from an unknown cause (also called “cryptogenic stroke”) and also have an opening between the two upper chambers of the heart that never fully closed after birth. The medical term for this opening in the heart is a patent foramen ovale (PFO). The information in this patient guide will help you learn more about cryptogenic stroke, PFO, and treatments to reduce the chance of having another stroke. Be sure to ask your

Foramina of the Skull and the Structures that Pass Through Remember, the accessory nerve, cranial nerve XI passes through the jugular foramen and also through the foramen magnum. It’s got two roots. You’ve got the roots up here and the spinal roots, which pass through the foramen magnum.he jugular foramen has loads of structures that pass through it. It’s called the ‘jugular foramen’ for a reason, because the internal jugular passes through it. I’ve just flipped back to the base of the skull view.
