Protuberance may refer to: Mental protuberance; Occipital protuberances, of which may refer to Internal occipital protuberance; External occipital protuberance;
Near the middle of the squamous part of occipital bone is the external occipital protuberance, the highest point of which is referred to as the inion. The inion is the most prominent projection of the protuberance which is located at the posterioinferior (rear lower) part of the human skull. The nuchal ligament and trapezius muscle attach to it.
The symphysis of the external surface of the mandible divides below and encloses a triangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle. The size and shape of the bones making up this structure are responsible for the size and shape of a person's chin.
These terms are derived from tuber (Latin: swelling)., [8] as is also protuberance, which occasionally is synonymous with "tuberosity". A ramus (Latin: branch) refers to an extension of bone, [9] such as the ramus of the mandible in the jaw or superior pubic ramus. Ramus may also be used to refer to nerves, such as the ramus communicans.
The occipital bun is a protuberance of the occipital bone. Its size and shape has been compared to that of a dinner roll. It is a quintessential trait of Neanderthals, though it is a trend in archaic Homo species. The true purpose of the occipital bun has not yet been defined. [3] However, some studies have found possible evolutionary purposes.
The occipital condyles are undersurface protuberances of the occipital bone in vertebrates, which function in articulation with the superior facets of the atlas vertebra.. The condyles are oval or reniform (kidney-shaped) in shape, and their anterior extremities, directed forward and medialward, are closer together than their posterior, and encroach on the basilar portion of the bone; the ...
The confluence of sinuses is found deep to the internal occipital protuberance of the occipital bone of the skull. [1] This puts it inferior to the occipital lobes of the brain, and posterosuperior to the cerebellum. [1] It connects the ends of the superior sagittal sinus, the straight sinus, and the occipital sinus. [1]
The topographic structure which is externally visible and colloquially called the "Adam's apple" is caused by an anatomical structure of the thyroid cartilage called the laryngeal prominence or laryngeal protuberance protruding and forming a "bump" under the skin at the front of the throat.
