Tyrannoneustes lythrodectikos was a giant marine crocodile that lived in the Middle Jurassic seas around 165 million years ago. The name means "blood-biting tyrant swimmer" in ancient Greek.

The cranial sinuses are eight cavities within the skull that supply vocal resonance. When they become inflamed, often accompanied by facial pain, fever, and nasal congestion, the condition is called ...

Other causes, such as direct cranial trauma, neurosurgical procedures in the area of a venous sinus, and bacterial meningitis, are also apparent before cerebral venous thrombosis.

A team of scientists have reported that the sinuses of the prehistoric ancestors of crocodiles prevented them from evolving into deep divers.

A cranial CT scan of the head is a diagnostic tool used to create detailed pictures of the skull, brain, paranasal sinuses, and eye sockets.

Thrombosis of the sinuses leads to increased venous pressure, impaired absorption of cerebrospinal fluid, and consequently, increased intracranial pressure.

The functions of the cranial nerves are sensory, motor, or both. Sensory cranial nerves help a person see, smell, and hear. Motor cranial nerves help control muscle movements in the head and neck.

However, metabolic imaging did not demonstrate any evidence of intracranial extent beyond the dural disease noted on earlier MRI sinus evaluation (Figures 6a and 6b).

The imaging assessment of structures and compartments that are critical to the skull base team are highlighted: orbit, cavernous sinus, anterior cranial fossa dura/intracranial tumor, lateral ...

Challenges of Brain Transfer: 1. Impossibility to extract the brain proper from the dura mater, given the intimate relationship between the brain’s venous and cerebrospinal fluid (CSF) outflow and the ...

They found that brain-case sinuses reduced across thalattosuchian evolution as they became more aquatic, in a similar way to those of whales and dolphins, possibly for diving and feeding.
