However, spinothalamic sensory signs are contralateral (on the right) because the spinothalamic tract crosses. Left (ipsilateral) tongue, right-sided (contralateral) weakness means the exiting left hypoglossal nerve has been affected (within the left medulla). B is in the pyramid where the corticospinal tract runs to control muscles (prior to the decussation). This is known as medial medullary syndrome or Dejerine syndrome The PICA supplies the dorsal lateral medullary plate and portions of the posterior medial cerebellum (uvula, nodulus and probably portions of the paraflocculus). Occlusion of its distal cerebellar branches can produce a syndrome very difficult to distinguish from a peripheral labyrinthine disorder, with vertigo, dysequilibrium and spontaneous.

Occlusion produces the medial medullary syndrome, characterized by contralateral hemiparesis of the lower extremities and trunk due to corticospinal tract involvement. Medial lemniscus involvement leads to diminished proprioception on the contralateral side, and ipsilateral paralysis of the tongue ensues from damage to the hypoglossal nucleus Medial inferior pontine syndrome has been described as equivalent to Foville's syndrome. Although medial pontine syndrome has many similarities to medial medullary syndrome, because it is located higher up the brainstem in the pons, it affects a different set of cranial nuclei 5-hydroxytryptamine from L-tryptophan. plays a rold in mood aggression and the induction of non-rapid eye movement (REM) locus caeruleus. synthesize NE and send projections to most brain areas involved in the contorl of cortical activation (arousal ) decreases levels of NE are evident in REM, paradoxic sleep.

  1. A vast network of nerve tracts in the central nervous system (CNS) which spans the cerebral cortex, brainstem, cerebellum, and spinal cord control the initiation and modulation of movements. The nerves in the CNS which carry the impulses for movement are known as upper motor neurons (UMN). The primary tract which carries signals for voluntary movement is known as the pyramidal tract
  2. Lateral pontine syndrome. Vomiting, vertigo, nystagmus (damage to vestibular nuclei), paralysis of face, decreased lacrimation, salivation, decreased taste from anterior 2/3 of tongue, decreased corneal reflex, decreased pain and temp sensation from face, ipsilateral hearing loss, ipsilateral Horner's syndrome (Damage to nuclei of CN VII, CV V, CN VIII, and sympathetic fibers)

  4. Marfan syndrome is NOT a collagen disorder. Elastin and fibrillin work together. Fibrillin is a glycoprotein that forms a sheath around elastin. In other words, it forms a scaffold in which elastin can be deposited. Once again, Marfan syndrome is not a collagen disorder. The USMLE really wants you to be able to contrast elastin from collagen

Brown-Séquard syndrome, first described by the physiologist Charles-Édouard Brown-Séquard, is a condition associated with hemisection or damage to one half of the spinal cord. The hemisection damages neural tracts in the spinal cord that carry information to and from the brain It is associated with polycystic kidney disease, medullary sponge kidney and medullary cystic disease. So looking at the kidneys can sometimes help you make this diagnosis. In images below Notice the intrahepatic duct dilatation and the normal caliber of the choledochal duct (extrahepatic bile duct) In a study of 100 patients with putaminal hemorrhage, Weisberg et al. 437 established the following clinicoanatomic correlations:. 1. Medial hemorrhages extended medially from the putamen and involved the genu and posterior limb of the internal capsule. This finding correlated with a contralateral hemisensory syndrome, but there were no abnormalities of ocular motility, visual fields, or level. Passes backwards in the brainstem, decussates in the anterior medullary velum and emerges to pass round the cerebral peduncle between it and the temporal lobe, passing over the tentorium to enter the cavernous sinus with II and VI, and enters the orbit to supply the superior oblique muscle. Signs. Diplopia due to weakness of downward and inward. d. Structures in the brainstem that contain UMNs include the red nucleus, the pontine and medullary reticular formation, and the lateral and medial vestibular nuclei. 3. The corticospinal, rubrospinal, and medullary (lateral) reticulospinal tracts arise from lateral or flexor-biased UMNs (Figures 3-4 and 3-5). a Renal tubular acidosis (RTA) occurs when the kidneys do not remove acids from the blood into the urine as they should. The acid level in the blood then becomes too high, a condition called acidosis. Some acid in the blood is normal, but too much acid can disturb many bodily functions. There are three main types of RTA
