what is the aos? the aos consists of 3 nuclei at the mesodiencephalic border that receive direct retinal input from the accessory optic tract (aot) (figure 1). the aot comprises an inferior and a superior fasciculus, with its superior fasciculus divided into a posterior branch, a middle ...
The human brain is made of several parts. The cerebrum is the largest part that comprises of the l.ft and the right hemispheres. The brain coordinates all vital physical and psychological processes such as swallowing, heartbeat, memory, and attention, among others. This question is about ...
The brain is the control center for the body and comprises three major regions: cerebrum, cerebellum, and the brain stem. The cerebrum, being the largest of all the regions, is also the most recognizable part. This region is separated into four smaller sections known as the frontal, parietal...
In turn, the brain stem comprises the medulla, pons, midbrain, hypothalamus and thalamus [source: Health Pages]. Within each of these structures are centers of neuronal cell bodies, called nuclei, which are specialized for particular functions (breathing, heart-rate regulation, sleep): Medulla -...
Nerve cells, also known asneurons, form the building blocks of nerves. Each neuron comprises a cell body, dendrites, and an axon. The cell body, or soma, is the control center of the neuron. It holds the nucleus and other essential components in thecell’smetabolism and maintenance. ...
The superior fasciculus is the topmost fiber bundle of the middle cerebellar peduncle. Originating from the pons' upper transverse fibers, the superior fasciculus is primarily dispensed to the small lobes of thecerebellar hemispheres. These are the two lateral lobes that comprise the cerebellum. ...
Second, it became obvious that neuroglia comprises many types of cells with very distinct physiological properties, and some of these cells are endowed with electrical excitability. In particular, the “fifth type” (besides astrocytes, oligodendrocytes, microglia and ependymal cells) of neuroglia, ...
For neurons, the second level of branches is driven by major brain structures/regions, and the third level comprises various cell subclasses and types within each major brain structure, although there may be cell types crossing or shared between brain structures due to cell migration during ...
neurodegenerative disorders mainly with a prenatal onset. Patients have severe hypoplasia or atrophy of cerebellum and pons, with variable involvement of supratentorial structures, motor and cognitive impairments. Based on distinct clinical features and genetic causes, current classification comprises 11 types...
The brain can be divided into four lines: frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The Cerebrum interior comprises grey matter in the cortex, and deep regions are made up of white matter. Posterior to the cerebrum is the brain stem and cerebellum. ...
