The transverse sinuses pass horizontally from the most posterior point of the occiput. It starts at the midline of the occiput and connects to the upper trapezius. The occiput wide at base and narrowing dorsally (to give it a triangular shape). In an occiput posterior position, labor becomes prolonged and more operative interventions are deemed necessary. The hind foot measures in length, while the ears are long from the occiput. In the vertex presentation the head is flexed and the occiput leads the way. Its skull is heavy with a basal length above and an occiput above . There is a defined furrow between the eyes (from the stop to the occiput). This headache often pulsates towards the occiput (the back of the head). The difference is that this time, the deformity mostly shows at the occiput. The identification of the location of the fetal occiput is important in delivery. About two-thirds of fetuses present with their left occiput (back of the head) at birth. A dark eyestripe extends backwards from the eye towards the occiput. The suboccipital muscles are a group of muscles defined by their location to the occiput. The superficial dermal elements are preserved, and the occiput is visible.
