Sulcus Anatomy

The cerebral cortex or the outer layer of the cerebrum consists of gyri that are typically surrounded by one or more sulci. Gyri and sulci give the brain its wrinkled appearance.

The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe.

Sulcus anatomy. A brain ridge is known as a gyrus plural. In a monograph bonin and bailey list the following as the primary sulci. The rouvieres sulcus is a fissure on the liver between the right lobe and caudate process and is clearly seen during a lc during the posterior dissection in a majority of patients 4 figure 6.

Sulci is a furrow or fissure. Lateral fissure or sylvian fissure la. The olfactory sulcus is located on the inferior orbital surface of the frontal lobe and runs in an anteroposterior direction.

One of the grooves or furrows on the surface of the brain bounding the several convolutions or gyri. An example is the superior pulmonary sulcus. The superior pulmonary sulcus or just the superior sulcus refers to an apical pleuro pulmonary groove formed by the subclavian artery as it curves in front of the pleura runs upward and lateral immediately below the apex.

Any long narrow groove furrow or slight depression. It corresponds to the level of the porta hepatis where the right pedicle enters the liver. The gyrus rectus lies medial to the olfactory sulcus whilst the orbital gyri lie lateral to it.

A groove furrow or trench. Its identification may help avoid bile duct injury during laparoscopic cholecystectomy and enables elective vascular control during segment oriented approach to right liver resection. Rouvieres sulcus is a frequent anatomical landmark present in 82 of the livers either as open or fused type.

A groove or depression in the oral cavity or on the surface of a tooth. The lateral sulcus also called sylvian fissure or lateral fissure is one of the most prominent features of the human brain. It may be a groove in the surface of a limb or an organ notably in the surface of the brain but also in the lungs certain muscles including the heart as well as in bones and elsewhere.

In biological morphology and anatomy a sulcus pl. The plural is sulci. It is a typical location for pancoast tumours also known as superior sulcus tumours that arise from pulmonary tissue.

Gyri and an indentation or depression is a sulcus plural. In anatomy there are many sulci.
