Image of the human brain showing sulci, gyri, and fundi shown in a Coronal section. Specific terms are used to represent the gross anatomy of the brain: A gyrus is an outward folding of the brain, for example the precentral gyrus. A sulcus is an inward fold, or valley in the brain's surface - for example the central sulcus. Additional terms ...
Association fibers are axons (nerve fibers) that connect cortical areas within the same cerebral hemisphere. [1]In human neuroanatomy, axons within the brain, can be categorized on the basis of their course and connections as association fibers, projection fibers, and commissural fibers. [1]
The uncus is an anterior extremity of the parahippocampal gyrus.It is separated from the apex of the temporal lobe by a sulcus called the rhinal sulcus. [1] Although superficially continuous with the hippocampal gyrus, the uncus forms morphologically a part of the rhinencephalon.
It is the superior part of the neurocranium and covers the cranial cavity containing the brain. It forms the main component of the skull roof . The calvaria is made up of the superior portions of the frontal bone , occipital bone , and parietal bones . [ 1 ]
Projection fibers consist of efferent and afferent fibers uniting the cortex with the lower parts of the brain and with the spinal cord.In human neuroanatomy, bundles of axons (nerve fibers) called nerve tracts, within the brain, can be categorized by their function into association tracts, projection tracts, and commissural tracts.
There are several methods that can be implemented to achieve primary closure of a wound, including suture, staples, skin adhesive, and surgical strips. Suture is the most frequently used for closure. [27] There are many types of suture, but broadly they can be categorized as absorbable vs non-absorbable and synthetic vs natural.
In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements. [ 1 ] Sutures are found in the skeletons or exoskeletons of a wide range of animals, in both invertebrates and vertebrates .
Functional magnetic resonance imaging (fMRI) was employed to determine areas of activation in the cerebellar cortex in humans during a series of motor tasks. The activation areas for movements of lips, tongue, hands, and feet were determined and found to be sharply confined to lobules and sublobules and their sagittal zones in the rostral and caudal spinocerebellar cortex.
