Technically, most people only have one external occipital protuberance, because it is right in the middle of back part of the head. But people can have slight asymmetry of their skulls -- which may related to how the skull was molded after birth, and so this is not that unusual.

Newsweek Newsletter sign-up > Of the group, 41.. The occipital bone articulates with the temporal bones, parietal bones, and sphenoid bone. Each of the temporal bones is composed of two portions: a large, flat plate, the squamous portion; and a thickened, wedge-shaped area, the petrous portion The foramen magnum (Latin: large hole) is a large oval foramen longest front to back; it is wider behind than in front where it is encroached upon by the occipital condyles. The clivus, a smooth bony section, travels upwards on the front surface of the foramen, and the median internal occipital crest travels behind it

The external surface is convex and presents midway between the summit of the bone and the foramen magnum a prominence, the external occipital protuberance.Extending lateralward from this on either side are two curved lines, one a little. The medulla oblongata is an extension of the spinal cord and reaches up into the brain. The human skull is actually formed by the fusion of 22 different bones to create a protective covering for the brain.Of those bones, however, the occipital bone is one of eight that creates what is known as the neurocranium or braincase, the back area of the skull that houses the brain The person who posted below is correct. This is where the temporal bone meets the zygomatic process/arch, 2 bones of the skull found in 100% of the population. On some, it is just more prominent.

Occipital reduction is done through a horizontal scalp incision usually located directly over the most projecting area or lower down at the nuchal ridges at the bottom of the hairline. Occipital Knob Reduction. The occipital knob is a central projection of bony overgrowth on the lower end of the occipital bone Osteochondroma is an overgrowth of cartilage and bone that happens at the end of the bone near the growth plate. Most often, it affects the long bones in the leg, the pelvis, or the shoulder blade. Osteochondroma is the most common noncancerous bone growth. It most often occurs between ages 10 and 30. It affects males and females equally
Transverse grooves, one on either side, extend from the internal occipital protuberance to the lateral angles of the bone; those grooves accommodate the transverse sinuses, and their prominent margins give attachment to the tentorium cerebelli cial asymmetry [7,25]. If one side of the back of the head is se-verely flattened, the occipital bone is pushed towards the oppo-site side on the back of the head, causing the opposite occipital bone to protrude prominently. Greater force of gravity is ap-plied to regions with a larger surface area. As the frontal bone OBJECTIVES: Occipital petalia is an anatomic description where one of the occipital lobes protrudes towards the contralateral side.

FIG. 129- Occipital bone. Outer surface They also recall their baby preferred to sleep in one position with the head turned to one side. Some babies may prefer to sleep with the back of the head on the mattress, not turning it to either side.

The Strangest Muscle in the Body. The sternocleidomastoid muscle, or SCM is to me, one of the most fascinating muscles in the body. Most people are totally unaware of its existence, as it sits innocently in the front of the neck. The reason for the lack of awareness is because it rarely hurts: I have only had two patients who actually felt pain. The median atlantoaxial joint contains two synovial cavities, one on each side of the dens of axis. The posterior synovial cavity, between the dens and the transverse ligament, is the larger of the two. Each synovial cavity is enclosed by a thin joint capsule lined by synovial membrane

The occipital bone is the single bone that forms the posterior skull and posterior base of the cranial cavity (; see also ). On its outside surface, at the posterior midline, is a small protrusion called the external occipital protuberance , which serves as an attachment site for a ligament of the posterior neck L.K. Blackburn The occipital lobe is the part of the brain that helps turn what the eyes see into meaningful information. The left occipital lobe is the left side of the region in the brain responsible for visual perception. It is located at the back bottom portion of the skull, behind the temporal lobe and below the parietal lobe

Locate the features boldfaced and described below in Parts iv-vi, and indicate which arrow on the images on p. 131 points to each feature.Part iv. On the posterior side of the distal end of the humerus, there is a feature called the olecranon fossa A, The jugular foramen is located between the temporal and occipital bones.One can-not see directly through the foramen from above, as shown, because it is directed forward under the temporal bone. The sigmoid groove descends along the mastoid and crosses the occipitomastoid suture where it turns forward on the upper surface of the jugular process of the occipital bone and enters the foramen. So the Occipital bone is two boney protrusions that stick out slightly at the base of the neck and the skull. It's a popular pressure point for massage therapists to work---a lot of people hold tension there and it feels really good when you press on the ligaments and muscles connecting the neck to the skull around there Occipital spurs, also called as occipital knob, occipital bun, chignon or inion hook, is an exaggerated external occipital protuberance (EOP). It is frequently discussed in anthropological literature as a Neanderthal trait but hardly reported and considered as a normal variant in medical literature. It is a frequent finding among males and hence a prominent occipital spur is often used in.
The sternocleidomastoid muscle (also known as sternomastoid) is found in the neck.It has two heads that meld to form one insertion. Sternocleidomastoid muscle, along with the trapezius muscle, is invested by the superficial layer of the deep cervical fascia, which splits around it.Sternocleidomastoid muscle divides the neck into anatomical anterior and posterior triangles Often the sinus is deviated to the side, again over the occipital region. which assist, sometimes quite a lot. Most of us are familiar with occipital emissary veins, which are located in the occipital bone, posterior to the jugular foramina. The transverse sinus is more often asymmetric than not — usually the right one is bigger, some. Behind the carotid canal is the jugular foramen, a large aperture, formed in front by the petrous portion of the temporal, and behind by the occipital; it is generally larger on the right than on the left side, and may be subdivided into three compartments. The anterior compartment transmits the inferior petrosal sinus; the intermediate, the. Major Cranial Features Review 1. Foramen magnum: Large hole at base of the skull that joins with the vertebral column. (Latin for hole + great) 2. External auditory meatus: Ear canals in the left and right temporal bones. (L & R) 3.

Occipital neuralgia is caused by trauma to or infection of the occipital nerves, oftentimes, because of a head injury or pinched nerve. The pain feels like a migraine, with burning and throbbing pain behind the eyes accompanied by shooting pain that starts at the base of the skull and radiates upward to the top of the head 1) Flatness on one side of the back of the head (plagiocephaly) is one of the most common skull shape deformities. 2) Plagiocephaly correction by a custom skull implant must take into consideration the potential stretch of the scalp tissues. 3) Static scalp expansion is usually sufficient for many larger custom skull implant placements
