Medullary reticular formation controlling breathing
Midbrain pneumotactic center
Reticulospinal tract innervating the diaphragm

Rate this question:
Amacrine cells are specific inner ear cells, responsible for the K+ transport to the hair cells
Amacrine cells are found in the outer nuclear layer of the retina and synapse with the rod photoreceptors
Amacrine cells are bipolar interneurons situated in the pretectal nuclei to influence the pupillary reflex
Amacrine cells are olfactory interneurons, which receive primary input from the olfactory nerves and mitral cells
Amacrine cells are found in the inner nuclear layer of the retina, are interneurons and synapse mainly with the ganglion cells
Rate this question:
Meningioma in the optic canal leading to compression of the optic nerve
Pituitary adenoma, causing compression of the optic chiasma and leading to hormonal deficiencies.
Carotid aneurysm leading to compression of the optic chiasma and constant headaches.
Multiple sclerosis, causing degeneration of the optic radiation leading to bitemporal hemianopia.
Multiple sclerosis based on her gender and young age, and the demyelination symptoms in both optic nerves.
Rate this question:
The tumor is compressing the vagal nerve in the mediastinum, causing loss of parasympathetic innervation of the eyelid
The tumor is compressing the sympathetic trunk on the neck, leading to the loss of sympathetic innervations of the tarsal muscle, thus leading to ptosis
There is metastasis in the mesencephalon, leading to trochlear nerve palsy, thereby causing ptosis
The tumor is compressing cranial nerve X on the neck, and this leads to sympathetic overstimulation of the eye muscles
The tumor is compressing the sympathetic trunk in the mediastinum, and therefore, the innervation of the orbital muscle is lost, and this leads to ptosis
