The ophthalmic nerve is the first branch of the trigeminal nerve, which is also known as the fifth cranial nerve. The ophthalmic nerve supplies sensory innervation to the structures of the eye, ...

The vestibular nerve (the eighth cranial nerve) is essential for regulating balance. Sensory structures in your inner ears detect head and body movement. The vestibular nerve carries that information ...

The parasympathetic pathway within the third cranial nerve induces pupil constriction, whereas the sympathetic pathway causes pupil dilation.1 Comparing pupil sizes in dim and bright lighting can help ...

In this update we will categorize pain syndromes into migraines, facial pain with or without Horner's syndrome, and headaches associated with other cranial nerve involvement. Intraocular findings ...

As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to ...

Frequent, severe headaches that worsen over time are one of the most common signs of a brain tumour. These headaches are ...

Dec. 6, 2024 — People who climb too fast or too high risk acute altitude sickness, which can lead to life-threatening hypoxic brain injury. By using in vivo electrochemistry, researchers ...

Another key difference is the complexity of paediatric examination. How exactly does one do a cranial nerve examination on a 4-day-old infant? What does it mean when you palpate a 2-year-old child’s ...

In further cellular studies, the researchers discovered two mechanisms that explain the NRP1's role in pain. First, when binding to nerve growth factor, NRP1 increases the local concentration of ...

These useful findings analyze the impact of the conditional deletion of Meis2 using the Wnt1 driver on whisker development and their interaction with trigeminal nerves. The evidence supporting the ...

In some cases, the reason for this may be a signaling pathway that controls auditory sensory cell function and is downregulated with ... How the Ear Can Inform the Brain of Whether Hearing Is Impa ...
