Sulcus Anatomy

A brain ridge is known as a gyrus plural. The olfactory sulcus is located on the inferior orbital surface of the frontal lobe and runs in an anteroposterior direction.

Lobes Of The Brain Queensland Brain Institute University

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.

Sulcus anatomy. An example is the superior pulmonary sulcus. In anatomy there are many sulci. The plural is sulci.

The gyrus rectus lies medial to the olfactory sulcus whilst the orbital gyri lie lateral to it. 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. The lateral sulcus also called sylvian fissure or lateral fissure is one of the most prominent features of the human brain.

In biological morphology and anatomy a sulcus pl. Any long narrow groove furrow or slight depression. One of the grooves or furrows on the surface of the brain bounding the several convolutions or gyri.

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

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. Gyri and an indentation or depression is a sulcus plural. Rouvieres sulcus is a frequent anatomical landmark present in 82 of the livers either as open or fused type.

Lateral fissure or sylvian fissure la. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe. Sulci is a furrow or fissure.

In a monograph bonin and bailey list the following as the primary sulci. A groove or depression in the oral cavity or on the surface of a tooth. It corresponds to the level of the porta hepatis where the right pedicle enters the liver.

It is a typical location for pancoast tumours also known as superior sulcus tumours that arise from pulmonary tissue. Its identification may help avoid bile duct injury during laparoscopic cholecystectomy and enables elective vascular control during segment oriented approach to right liver resection.
