Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA This video provides an overview of sinus, nose, and throat examinations. The demonstration begins with a brief overview of the anatomy of the region. The upper third of the nose is bony, and the bottom two-thirds are cartilaginous. Air entering the nares passes through the nasal vestibules and into the narrow passageway between the nasal septum...

Cre-LoxP Mediated Induction of Cerebral Cavernous Malformations in a Mouse Model

2025
In this video, a genetically modified mouse pup carrying the Ccm2 gene flanked by loxP sites and Cre recombinase fused to an estrogen receptor is used to induce cerebral cavernous malformations (CCMs). The administration of 4-hydroxytamoxifen activates Cre in endothelial cells, leading to the deletion of Ccm2 and the formation of CCMs in the brain.

FAQs
Venous blood enters the cavernous sinus from ophthalmic and cerebral veins and leaves through connections with the superior and inferior petrosal sinuses. This arrangement links drainage from the orbit and brain with larger venous pathways at the skull base. Studying these connections helps explain how blood from multiple regions is routed through a compact dural-lined channel.
The internal carotid artery passes through the cavernous sinus alongside structures involved in cranial nerve function. Their close anatomical relationship means that a lesion affecting this region can involve both vascular and neural elements. This makes the cavernous sinus a useful example of how blood vessels, venous channels, and nerves are organized together within a confined part of the skull.
Several cranial nerves pass through or along the walls of the cavernous sinus and contribute to eye movement or facial sensation. Because these functions depend on intact nerve pathways, disease or injury in the sinus region can produce deficits in those systems. The anatomy therefore connects a localized venous structure with recognizable neurological outcomes.
Infections, thrombosis, tumors, and trauma involving the cavernous sinus or nearby regions can interfere with its normal anatomical relationships. The resulting effects may include impaired eye movement, altered facial sensation, or vision problems. These outcomes reflect disruption of the venous channel itself, neighboring neural structures, or the internal carotid artery within this compact region.
A focused study should trace the incoming ophthalmic and cerebral veins, the outgoing superior and inferior petrosal sinuses, and the structures that traverse or border the channel. Mapping these relationships clarifies how orbital, cerebral, and facial regions connect with skull-base venous drainage. It also provides a framework for relating structural changes to neurological or visual findings.
The cavernous sinus provides a compact model for studying venous drainage and neurovascular organization. Its paired arrangement, multiple venous connections, and close association with the internal carotid artery and cranial nerves allow learners to examine how different systems occupy shared anatomical space. This makes it relevant to both general biology and medical studies of skull-base structure.
Symptoms involving eye movement or facial sensation can be interpreted by considering the cranial nerves located within or alongside the cavernous sinus. If infection, thrombosis, tumor, or trauma affects this region, those neural pathways may be compromised. Relating the affected function to the sinus’s anatomy helps connect a clinical finding with a specific neurovascular location.
Because the cavernous sinuses occur as a pair at the skull base, their organization can be considered within the broader bilateral arrangement of cranial anatomy. Each side is associated with venous drainage from nearby regions and with important vascular and neural structures. This paired pattern helps researchers and students analyze local relationships without treating the sinus as an isolated channel.
