Fetal posterior The term is derived from the Latin term 'pirum' meaning a 'pear' and '-form', meaning having the form of a pear. The superior thyroid artery has several branches which include Internal carotid artery The superior thyroid artery has several branches which include The skull base and vault collectively form the neurocranium. The quadrigeminal cistern (also known as superior cistern or cistern of the great cerebral vein) is one of the CSF-filled subarachnoid cisterns.. The MCA arises from the internal carotid artery as the larger of the two main terminal branches (the other being the anterior cerebral artery), coursing laterally into the lateral sulcus where it branches to perfuse the cerebral cortex. The anterior intercostal branches of internal thoracic artery supply the upper five or six intercostal spaces. The parotid gland is wrapped around the mandibular ramus and extends to a position anterior and inferior to the ear. Such heaven! The maxillary artery is one of two terminal branches of the external carotid artery, along with the superficial temporal artery. Middle cerebral artery It then descends along the body of the internal carotid artery aiming towards the bifurcation of the common carotid artery. Epidemiology. Radiopaedia.org The cranial nerves (TA: nervi craniales) are the twelve paired sets of nerves that arise from the cerebrum or brainstem and leave the central nervous system through cranial foramina rather than through the spine. Furthermore, they are valveless, allowing for bidirectional blood flow from and into intracranial Radiopaedia.org Radiopaedia.org Fetal posterior The posterior cerebral artery curls around the cerebral peduncle and passes above the tentorium to supply the posteromedial surface of the temporal lobe and the occipital lobe. The maxillary artery originates deep to the neck of the mandible. Subclavian artery In radiology, the 'head and neck' refers to all the anatomical structures in this region excluding the central nervous system, that is, the brain and spinal cord and their associated vascular structures and encasing membranes i.e. The term is derived from the Latin term 'pirum' meaning a 'pear' and '-form', meaning having the form of a pear.

Parotid Open Access The Scalp Posterior cerebral artery medial occipital artery. venous The Sylvian fissure can be divided into superficial and deep Related pathology. The wide range of prevalence is attributable to variability in the definition used for Radiopaedia.org The superior thyroid artery is the first branch of the external carotid artery. The pulmonary trunk, also known as main pulmonary artery (mPA), (TA: truncus pulmonalis) is the solitary arterial output from the right ventricle, transporting deoxygenated blood to the lungs for oxygenation.. Lung fissures are a double-fold of visceral pleura that either completely or incompletely invaginate lung parenchyma to form the lung lobes.. Each lung has an oblique fissure separating the upper lobes from the lower lobes and the right lung has a horizontal fissure that separates the right upper lobe from the middle lobe.. parieto-occipital artery. Epidemiology. The anterior cerebral artery (ACA) along with the middle cerebral artery (MCA) forms at the termination of the internal carotid artery (ICA).It is the smaller of the two, and arches anteromedially to pass anterior to the genu of the corpus callosum, dividing as it does so into its two major branches; pericallosal and callosomarginal arteries (see below). basilar artery to interpeduncular cistern. Each lung weighs approximately 1.1 kg. Google There are numerous accessory Gross anatomy. Such heaven! Other functions are air humidification and aiding in voice resonance. The parotid gland is wrapped around the mandibular ramus and extends to a position anterior and inferior to the ear. Suprasellar There are numerous accessory The maxillary artery originates deep to the neck of the mandible. Zenker diverticulum, also known as a pharyngeal pouch, is a posterior outpouching of the hypopharynx, just proximal to the upper esophageal sphincter through a weakness in the muscle layer called the Killian dehiscence. numerous small branches. As the petrous part of the internal carotid artery leaves the carotid canal, it curves vertically and superiorly above foramen lacerum to enter the cavernous sinus.Here the artery is also referred to as the cavernous part.. There are three branches of the external carotid artery involved: Superficial temporal supplies the frontal and temporal regions Posterior auricular supplies the area superiorly and posteriorly to the auricle. posterior inferior temporal artery. Masticator Maxillary artery carotid cistern (paired): lateral to the suprasellar cistern, surrounds the supraclinoid internal carotid artery; perimesencephalic cisterns. Trigeminal nerve pes hippocampus landmarks. Pulmonary Open Access interpeduncular cistern (unpaired): between the cerebral crura; crural cisterns (paired): between the cerebral crus and uncus of the temporal lobe; ambient cisterns (paired): posterolateral to the midbrain It is located between the colliculi, the splenium of the corpus callosum and the superior surface of the cerebellum and extends from the third ventricle to the great cerebral vein.. The trigeminal ganglion is analogous to the It arises from the external carotid artery at the level of the hyoid bone. The skull base and vault collectively form the neurocranium. The mediastinum is a space in the thorax that contains a group of organs, vessels, nerves, lymphatics and their surrounding connective tissue. Gross anatomy Location. morphology: hippocampal digitations a.k.a. Vertebral artery The middle cerebral artery (MCA) is one of the three major paired arteries that supply blood to the brain. anterior lobe of the pituitary to basilar artery. Subclavian artery The cranial nerves are numbered one to twelve, always using Roman numerals, i.e.I to XII. Summary. Gross anatomy. Structure. It descends from the anterior surface of the external carotid artery along the lateral border of the thyrohyoid muscle towards the apex of the thyroid gland.. It is responsible for supplying a large portion of the anterior and middle parts of the brain. Concha bullosa Other functions are air humidification and aiding in voice resonance. (mnemonic) The base of the skull (or skull base) forms the floor of the cranial cavity and separates the brain from the structures of the neck and face. It descends from the anterior surface of the external carotid artery along the lateral border of the thyrohyoid muscle towards the apex of the thyroid gland.. Trigeminal nerve It is located between the colliculi, the splenium of the corpus callosum and the superior surface of the cerebellum and extends from the third ventricle to the great cerebral vein.. The suprasellar cistern is located above the sella turcica, under the hypothalamus and between the uncus of the temporal lobes. Supply. The artery then passes forwards to enter the cavernous sinus, and makes a 180 degrees turn back on itself and emerges lateral to the optic chiasm. the posterior amygdala is located above the anterior aspect of the hippocampal head 4. hippocampal head. carotid cistern (paired): lateral to the suprasellar cistern, surrounds the supraclinoid internal carotid artery; perimesencephalic cisterns. Summary. As the petrous part of the internal carotid artery leaves the carotid canal, it curves vertically and superiorly above foramen lacerum to enter the cavernous sinus.Here the artery is also referred to as the cavernous part.. Vertebral artery It is responsible for supplying a large portion of the anterior and middle parts of the brain. A fetal (origin of the) posterior cerebral artery is a common variant in the posterior cerebral circulation, estimated to occur in 20-30% of individuals 2.. The suprasellar cistern is located above the sella turcica, under the hypothalamus and between the uncus of the temporal lobes. Structure. Concha bullosa Dural venous sinuses are venous channels located intracranially between the two layers of the dura mater (endosteal layer and meningeal layer) and can be conceptualised as trapped epidural veins. calcarine artery. inferior alveolar artery and vein; pterygoid venous plexus; The masticator space contains fibroadipose tissue of potential spaces between the muscles and bones that can be described by the following subcompartments 9: submasseteric space; pterygomandibular space; temporal space. Cavernous sinus The parotid gland is wrapped around the mandibular ramus and extends to a position anterior and inferior to the ear. carotid artery The scalp receives a rich arterial supply via the external carotid artery and the ophthalmic artery (a branch of the internal carotid). The maxillary artery originates deep to the neck of the mandible. skull Each lung weighs approximately 1.1 kg. radicular/spinal branches. Beneath the mucous membrane of the anterior wall runs the internal laryngeal nerve, a branch of the superior laryngeal nerve. Within the sinus, the internal carotid artery travels anteriorly, in a horizontal manner until it reaches the anterior limit of the sinus. Concha bullosa is a normal variant and is one of the most common variations of sinonasal anatomy, it is identified in ~35% (range 14-53%) of patients 1..
