Of course, the champion epiphysis-bearer among diplodocoids is the weird little rebbachisauridNigersaurus. Here’s aNigersaurusmid-cervical, from Sereno et al. (2007: fig. 3). Note that the projecting portions of the epipophysis is roughly as long as the articular surface of the postzyg...
Wedel (2012) Fig. 2. The longest cells in the bodies of sauropods were sensory neurons that connected receptors in the skin of the extremities with interneurons in the brainstem, a pattern of neural architecture that is present in all extant vertebrates. The nerve cell bodies would have been ...
This can help maintain key functions in the wake of injury and is somewhat unique for the central nervous system, where not all structures are capable of rebuilding themselves. These structures originate in the medulla oblongata, a part of the brainstem. They twine up into the cerebellum, ...
Common to all vertebrates, the mesencephalon, also known as themidbrain, is the middle division of thebrain. Composed of two main regions — the tectum, or “roof” in Latin, and the tegmentum, or “covering” — it plays important roles in the sensory and motor control systems. The mid...
etiology of syringomyelia” [26], the traction of the spinal cord and brain is proposed as the main mechanism involved in the etiopathogenesis of ISM, ACSI, IS and other diseases also considered idiopathic, such as Platybasia, Basilar Impression, Retroflexed Odontoid and Brainstem Kinking [27, ...
Beyond the study of the episode itself, other different neurophysiologic assessments (Figure 1) disclosed increased excitability of motor areas [21,29], decreased activity of frontal areas after sleep deprivation [35], alteration of excitatory brainstem networks [38], a higher ability to perform com...
The middle cerebellar peduncle is one of the three stem like structures that connects the brain's cerebellum to the pons...
the brainstem–which receives sensory fibers from the vagus nerve–was active in the process. I assume that there is some esoteric bit of embryology that explains how vagus fibers end up in the vagina, probably something to do with themesonephric ducts. But I don’t know what that is off...
This one shows the whole cord, brainstem, thalamus, and cerebral cortex in coronal section, in cartoon form. It’s for drawing in ascending sensory and descending motor pathways, as shown in this office hours sketch. DC-ML is dorsal column/medial lemniscus, which carries discriminative touch ...
These structures originate in the medulla oblongata, a part of the brainstem. They twine up into the cerebellum, creating a deeply branched structure that connects with individual cells known as Purkinje cells. Each climbing fiber is capable of splitting to come into contact with multiple cells. ...
