coronary sulcus The central sulcus lies approx. midway along the lateral surface of the cerebral hemisphere, between the frontal and occipital poles of the brain. The gyrus anterior to the central sulcus -- the precentral gyrus -- is the primary motor cortex, and the gyrus posterior to the central sulcus -- the postcentral gyrus -- is the primary sensory cortex. Occasionally, the central sulcus is interrupted and is not a continuous groove from top to bottom.

sulcus Large sulci that divide the brain into lobes as well as the two hemispheres are more often called fissures. Plural: sulci. See fissure. calcarine sulcus See calcarine fissure. ciliary sulcus A groove situated between the posterior root of the iris and the ciliary body. It may be used, sometimes, as a site of fixation of an intraocular lens implant. See intraocular lens.

Coronary sulcus It is located between the left atrium and ventricle. Coronary sulcus Function. It contains the trunks of the blood vessels that are known as the “nutrient vessels of the heart”. It comprises of veins and arteries that supply blood to the cardiac muscles and also carries it from them. It gives passage to the Coronary sinus, Coronary veins and Coronary arteries.

Posterior Horn of the Medial Meniscus Longitudinal Tear of the Posterior Horn Medial Meniscus. The posterior horn of the medial meniscus is that portion of the medial meniscus in the back part of the knee. It varies from the main weightbearing portion of the meniscus up to where it attaches on the tibia at its lateral aspect, called the root attachment.

- The postcentral gyrus which is also called the primary sensory area or the sensory strip is immediately posterior to the central sulcus. This area receives sensory feedback from joints and tendons in the body and is organized in the same manner as the motor strip.reas involved in the processing of auditory information and semantics as well as the appreciation of smell are found in the Temporal Lobe. Area 41 is Heschl's gyrus, the primary auditory area. Area 42 immediately inferior to area 41 and is also involved in the detection and recognition of speech.

Central Sulcus Named after Luigi Rolando, the central sulcus (of Rolando) or Rolandic fissure is a part of the brain that extends from the cerebral longitudinal fissure up to near the lateral sulcus (of Sylvius) or Sylvian fissure perpendicularly.t separates the frontal lobe and parietal lobe. It divides the sensory and motor areas of the brain [ 4 ]. The identification of central sulcus is extremely important in neurosurgery. It serves as a guide in determining the cortical areas of the brain.

Lateral sulcus The lateral sulcus (also called Sylvian fissure or lateral fissure) is one of the most prominent structures of the human brain.natomy [edit]. The lateral sulcus divides both the frontal lobe and parietal lobe above from the temporal lobe below. It's in both hemispheres of the brain but is longer in the left hemisphere in most people. The lateral sulcus is one of the earliest-developing sulci of the human brain.

Geotagging With Android Smartphones Geotagging With Android Smartphones. Geotagging is the act of including geographical information about where a photo was taken in with the digital photo file. Geotagging is extremely helpful to anyone who takes a large number of pictures and needs a way to record exactly where each photo was taken. By default, the camera application on your Android smartphone has the ability to add GPS coordinates to the image file, but there are a few settings you have to change for this feature to work correctly. 1  1. Go to your Android device's home screen, then press the Menu button.

What is the function and location of the thalamus? The thalamus is typically (depending on the animal) ventral and medial in relation to the cortex, and anterior to the midbrain. It lies just ventral from the third ventricle. Its function is to relay information from the sensory organs (except the olfactory system), the hindbrain, midbrain, and the spinal cord to the cortex, hippocampus and basal ganglia. For example, the lateral geniculate nucleus recieves innervation from the retina and relays it to the visual cortex.

Interior Skull In the median area the floor is formed by the body of the sphenoid. In front, the optic groove (sulcus chiasmatis) leads on each side into the optic foramen. The sulcus does not lodge the optic chiasma, which lies above and behind it.

- The choroid fissure is formed by invagination of the ependyma of the medial wall of the lateral ventricle and ingrowth of vascular tissue that will form the choroid plexus. In the temporal lobe, the fissure is alongside the hippocampus and fimbria, which form its inferior wall.
