sulci

Examples of sulci in the following topics:

• Overview of the Cerebrum

  • In larger mammals, the cerebral cortex is folded into many gyri and sulci, which allows it to expand in surface area without taking up much greater volume.
  • Notice the folded structure of the cortex: the "valleys" of the cortex are known as sulci.

• Medulla Oblongata

  • The region between the anterior median and anterolateral sulci is occupied by an elevation on either side known as the pyramid of medulla oblongata.
  • The posterior part of the medulla between the posterior median and posterolateral sulci contains tracts that enter it from the posterior funiculus of the spinal cord.

• Body Cavity Membranes

  • It is the meningeal envelope which firmly adheres to the surface of the brain and spinal cord, following the brain's minor contours (gyri and sulci).

• Meninges

  • It is the meningeal envelope that firmly adheres to the surface of the brain and spinal cord, following the brain's minor contours (gyri and sulci).

• Cerebral Lobes

  • At the front edge of the occipital there are several lateral occipital gyri separated by lateral occipital sulci.

• Cerebrospinal Fluid and Its Circulation

  • It constitutes the content of all intracerebral ventricles, cisterns, and sulci (singular sulcus), as well as the central canal of the spinal cord.
