Central sulcus From Wikipedia, the free encyclopedia. The central sulcus is a sulcus, or fold, in the cerebral cortex in the brains of vertebrates. Also called the central fissure, it was originally called the fissure of Rolando or the Rolandic fissure, after Luigi Rolando.It is sometimes confused with the medial longitudinal fissure.The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex.rom Wikipedia, the free encyclopedia.

Sulcus (neuroanatomy) Illustration depicting general brain structures including sulci. In neuroanatomy, a sulcus (Latin : furrow, pl. sulci) is a depression or groove in the cerebral cortex. It surrounds a gyrus (pl. gyri), creating the characteristic folded appearance of the brain in humans and other mammals.tructure [edit]. Sulci are one of three parts of the cerebral cortex, the others being the gyri and the fissures. The three different parts create a larger surface area for the human brain and other mammalian brains. When looking at the human brain, two-thirds of the surface is hidden in the grooves.

Nasal concha Each pair is composed of one turbinate in either side of the nasal cavity, divided by the septum. The superior turbinates are smaller structures, connected to the middle turbinates by nerve-endings, and serve to protect the olfactory bulb. The openings to the posterior ethmoidal sinuses exist under the superior meatus.

Anatomy Notes Technically, each crevice is called a sulcus (pl. sulci) and each ridge between the crevices is called a gyrus (pl. gyri). Sulci and gyri are simply a way of increasing the surface area of the cerebral cortex (and therefore the number of neurons) without greatly expanding the size of the skull.nstead of being smooth and nearly featureless like a kidney or spleen, the cerebral cortex (the thin layer of gray matter forming the outer surface of the brain) is chock-full of wrinkles and folds.

Fissure 1 Calcarin's fissure: extends from the occipital of the cerebrum to the occipital fissure. 2  Callosomarginal fissure: found in the mesial surface of the cerebrum. 3  Central sulcus or Rolando's fissure: separates the brain's frontal and parietal lobes. Medial longitudinal fissure or Longitudinal fissure: which divides the cerebrum into the two hemispheres. 2  Fissure of Bichat: found below the corpus callosum in the cerebellum of the brain. 3  Broca's fissure: found in the third left frontal fold of the brain.

definitions - Frontal lobereport a problem On the lateral surface of the human brain, the central sulcus separates the frontal lobe from the parietal lobe. The lateral sulcus separates the frontal lobe from the temporal lobe. The frontal lobe bottom can be divided into a lateral, polar, orbital (above the orbit; also called basal or ventral), and medial part.

- sulcus. A depression or a groove found on the surface of an organ or tissue, as on the surface of the brain separating adjacent convolutions. Large sulci that divide the brain into lobes as well as the two hemispheres are more often called fissures. Plural: sulci.See fissure.ulcus (sulˑ·k s) , n any of the narrow grooves in an organ or tissue, such as those that separate the convolutions of the cerebral hemisphere; used interchangeably with. fissure, although a sulcus is not as deep as a fissure.

Cerebrospinal fluid It constitutes the content of the ventricles, cisterns, and sulci of the brain, as well as the central canal of the spinal cord. There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphatic duct where the perilymph is continuous with the cerebrospinal fluid.

Meninges Normally, the dura mater is attached to the skull, in the spinal cord, the dura mater is separated from the bone (vertebrae) by a space called the epidural space, which contain fat and blood vessels. The arachnoid is attached to the dura mater, while the pia mater is attached to the central nervous system tissue. When the dura mater and the arachnoid separate through injury or illness, the space between them is the subdural space.

Sulcus (neuroanatomy) Limiting sulcus separates at its floor into two areas which are different functionally and structurally e.g. central sulcus between the motor and sensory areas. 1  Axial sulcus develops in the long axis of a rapidly growing homogeneous area e.g. postcalcarine sulcus in the long axis of the striate area.

Lobes of the brain It is separated from the parietal lobe by a space between tissues called the central sulcus , and from the temporal lobe by a deep fold called the lateral sulcus also called the Sylvian fissure. The precentral gyrus , forming the posterior border of the frontal lobe, contains the primary motor cortex , which controls voluntary movements of specific body parts.

Gross Anatomy of the Brain Each hemisphere has three poles. The frontal pole is the most anterior extent of the frontal lobe. The occipital pole is the most posterior extent of the occipital lobe. The temporal pole is the most anterior extent of the temporal lobe. The left and right cerebral hemispheres are separated by the longitudinal cerebral fissure. There are four key sulci (singular = sulcus: groove) in the cerebral hemispheres that divide the cerebral cortex into five (5) lobes. The central sulcus (sulcus of Rolando) is located just behind the most anterior vertical gyrus (plural gyri: convolution) on the lateral surface of each hemisphere.

- Many ridges called convolutions, or gyri, or gyrus, separated by grooves, mark the cerebrum 's surface. *Sulcus (sulci)- shallow grooves on the brain. Generally, a shallow to somewhat deep groove is called a sulcus, or sulci, and a very deep groove is called a fissure. Posted by Saketh Raghavan (student) on 15/3/13.

Structure of the Respiratory System Structure of the Respiratory System. The nose consists of the visible external nose and the internal nasal cavity. The nasal septum divides the nasal cavity into right and left sides. Air enters two openings, the external nares (nostrils; singular, naris), and passes into the vestibule and through passages called meatuses.
