Optic Nerve// by Shivani Rae// The optic nerves are solely sensory. #Repost @soton_brain_hub They convey visual information from each retina out of the eye and into the skull through the optic canals. The left and right optic nerves meet to form the optic chiasm, where fibres from the nasal half of each retina cross over. The optic tract continues to the lateral geniculate nucleus in the thalamus, from where optic radiations fan out to the primary visual cortex in the occipital lobe. The visual pathway is a useful diagram to be able to draw as it allows you to figure out where a lesion is when presented with a visual field deficit. Just shade in the parts of the visual field that are lost and track along the pathway to find the lesion! Using this method you can see for yourself how bitemporal hemianopia (bilateral loss of the temporal visual field) is most likely caused by damage at the optic chiasm. Enlargement of which nearby structure may be responsible for compression of the optic chiasm? #opticnerve #visualpathway #vision #nlm2 #nlm2soton #12days #12nerves #neuro #neuroanatomy #anatomy #clinicalanatomy #medstudent #medschool #medicina #neuroscience #clinical #neurosurgeryblog #neurocirurgiabr

The posterior triangle of the neck. Tip number 1. Look for the emergence of the brachial plexus between the scalene mass and the anterior scalene muscle. Tip2. The phrenic nerve runs along the surface of the anterior scalene muscle in the neck. #Repost @soton_brain_hub (@get_repost) ・・・ #nlm2soton #medstudent #neck #anatomy #medicalschool #medschool #medlife #premed #premedlife #medicina #neurocirurgiabr #neurosurgeryblog

#Repost @soton_brain_hub (@get_repost) ・・・ First day of Christmas//Olfactory Nerve// Here’s a quick one as promised so you can get back to your Christmas celebrations! The olfactory nerve has just a special sensory function: the sense of smell. Olfactory receptor cells in the olfactory mucosa pass through holes in the cribriform plate and synapse in the olfactory bulb. The olfactory bulbs continue as the olfactory tracts to the primary olfactory cortex and associated areas. Remember, the olfactory nerve (along with the optic nerve) differs from the other cranial nerves in that it doesn’t arise from the brainstem. We’ll be covering the optic nerve tomorrow so check back for more! #christmas #cranialnerves #12days #olfactorynerve #CNI #medstudent #anatomy #nlm2 #nlm2soton #neuroanatomy #anatomy #medicine #medicalschool #clinical #neuro #premed #medicina #medicalstudent #medicalschool #medicalschoollife #medlife #premedstudent #neurology #futuredoctor #medschoolproblems #medstudentproblems #medical #neuroscience
