The transverse occipital sulcus is a sulcus in the occipital lobe.. The transverse occipital sulcus is continuous with the posterior end of the occipital ramus of the intraparietal sulcus, and runs across the upper part of the lobe, a short distance behind the parietooccipital fissure.
The anterior portion is often incomplete, but in some individuals it may encounter the superior temporal sulcus whilst the posterior portion originates from the middle of the curved lunate sulcus, or from a curved portion of the transverse occipital sulcus if absent. [1]
The under surface of the jugular process is rough, and gives attachment to the Rectus capitis lateralis muscle and the lateral atlanto-occipital ligament; from this surface an eminence, the paramastoid process, sometimes projects downward, and may be of sufficient length to reach, and articulate with, the transverse process of the atlas.

The lateral part of the parieto-occipital sulcus (Fig. 726) is situated about 5 cm in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length. The medial part of the parieto-occipital sulcus (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure ...
From this protuberance the upper division of the cruciform eminence runs to the superior angle of the bone, and on one side of it (generally the right) is a deep groove, the sagittal sulcus, which lodges the hinder part of the superior sagittal sinus. To the margins of this sulcus the falx cerebri is attached.
The cruciform eminence (or cruciate eminence) divides the deeply concave internal surface of the occipital bone into four fossae: . The upper two fossae are called the cerebral fossae, are triangular and lodge the occipital lobes of the cerebrum.
The groove for transverse sinus is a groove which runs along the internal surface of the occipital bone, running laterally between the superior and inferior fossae of the cruciform eminence. The transverse sinuses travel along this groove.
