The vomer bone is one of the unpaired facial bones of the skull. It is located in the midsagittal line, and touches the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones. The vomeronasal organ, also called Jacobson's organ, is a chemoreceptor organ named for its closeness to the vomer and nasal bones, and is particularly developed in animals such as cats (who adopt a characteristic pose called the Flehmen reaction or flehming when making use of it), and is thought to have ...

The coccyx (Latin: os coccygis), commonly referred to as the tailbone, is the final segment of the human vertebral column, of three to five (usually four) fused vertebrae (the coccygeal vertebrae), below the sacrum. It is attached to the sacrum in a fibrocartilaginous joint, which permits limited movement between them. Coccyx - Function. The coccyx is regarded as vestigial in humans, meaning it no longer serves major functions it did in ancestor species of humans. (Those included suppor ...

The zygomatic bone (also known as the zygoma; Os Zygomaticum; Malar Bone) is a paired bone of the human skull. It articulates with the maxilla, the temporal bone, the sphenoid bone and the frontal bone. It forms part of the orbit and is commonly referred to as the cheekbone. It is situated at the upper and lateral part of the face: it forms the prominence of the cheek, part of the lateral wall and floor of the orbit, and parts of the temporal and infratemporal fossae [Fig. 1]. It presents a malar and a temporal surface; ...

The ulna (Elbow Bone) [Figs. 1, 2] is a long bone, prismatic in form, placed at the medial side of the forearm, parallel with the radius. Ulna - Articulations. The ulna articulates with: the humerus, at the elbow as a hinge joint. the radius, near the elbow as a pivot joint, this allows the radius to cross over the ulna in pronation. the distal radius, where it fits into the ulna notch.

Coelurosauria is a group of theropod dinosaurs that includes the subgroups Tyrannosauridae, Ornithomimidae, and Maniraptora. Coelurosaur characteristics include an extended sacrum, a distally stiffened tail and a bowed ulna. The tibia is also characteristically longer than the femur in coelurosaurs. Recent fossil evidence shows that some coelurosaurs were feathered, and it is conceivable (and indeed the most parsimonious hypothesis) that feathers may have been a feature of the entire group. Most coelurosaurs are bipedal ...

Vertebrae (singular: vertebra) are the individual bones that make up the vertebral column (aka spine) — a flexuous and flexible column. There are thirty-three (33) vertebrae in humans, including the five that are fused to form the sacrum (the others are separated by intervertebral discs) and the four coccygeal bones which form the tailbone. The upper three regions comprise the remaining 24, and are grouped under the names cervical (7 vertebrae), thoracic (12 vertebrae) and lumbar (5 v ...

There are three cuneiform bones in the human foot: the medial cuneiform, the intermediate cuneiform and the lateral cuneiform. They are located between the navicular bone and the first, second and third metatarsal bones and are medial to the cuboid bone. The first cuneiform (a.k.a. os cuneiform primum / medial cuneiform) is the largest of the cuneiforms. It is situated at the medial side of the foot, anterior to the navicular and posterior to the base of the first metatarsal. It articulates with four bones: the navi ...

The cuboid bone is one of seven Tarsal bones. Distally, the Cuboid articulates with the fourth and fifth metatarsals, forming the fourth and fifth tarsometatarsal joints. Proximally, it articulates with the calcaneus, forming the calcaneocuboid joint. The medial surface of the bone articulates with both the lateral cuneiform bone and the navicular bone. The inferior surface has a groove on its distal th ...

The Was is the Egyptian hieroglyphic character that stands for a word meaning power. In their 2004 book "The Quick and the Dead", Andrew H. Gordon and Calvin W. Schwabe speculated that the Ankh, Djed and Was symbols have a biological basis derived from ancient cattle culture, thus: the Ankh - symbol of life - thoracic vertebrae of a bull (seen in cross section) the Djed - symbol of stability - base or sacrum of a bull's spine the Was - symbol of power and dominion - a s ...

The capitate bone (os capitatum; os magnum) is a bone in the human hand. The capitate bone is the largest of the carpal bones, and occupies the center of the wrist. It presents, above, a rounded portion or head, which is received into the concavity formed by the navicular and lunate; a constricted portion or neck; and below this, the body. The superior surface is round, smooth, and articulates with the lunate bone. The inferior surface is divided by two ridges into three facets, for articulation with the second, third, and fourth metacarpal bones, that for the third being the largest.< ...

Andreas Vesalius (December 31, 1514 - October 15, 1564) was a Flemish anatomist and author of one of the most influential books on human anatomy, De Humanis Corporis Fabrica (On the Workings of the Human Body). Vesalius has been often been referred to as the founder of modern human anatomy. His name is also referred to as Andreas Vesal or Andreas van Wesel, depending on the source.

In tetrapods, the carpus is the cluster of bones in the hand between the radius and ulna and the metacarpus. The bones of the carpus do not belong to individual fingers, whereas those of the metacarpus do. The joint between the radius and ulna and the carpus is called the wrist. The corresponding part of the foot is the tarsus. The skeleton of the hand [Figs. 1, 2] is subdivided into three segments: the carpus or wrist bones; the metacarpus or bones of the palm; and the phalanges or bones of the d ...

The ankh (pronounced 'ahnk', symbol ☥) was the Egyptian hieroglyphic character that stood for the word ʿnḫ, which means life). Egyptian gods may carry it by the loop, or bear one in each hand crossed over their breast. Latinists interpreted the symbol as a crux ansata, "cross with a handle". Ankh - Origins. What it was intended to represent remains a mystery to Egyptologists, and no single hypothesis has yet been widely accepted. Some have speculated that it was a stylized womb. Si ...

Kundalini is derived from a Sanskrit word meaning either "coiled up" or "coiling like a snake". There are a number of other translations of the term usually emphasizing a more serpent nature to the word— e.g. 'serpent power'. The caduceus symbol of coiling snakes is thought to be an ancient symbolic representation of Kundalini physiology. The concept of Kundalini comes from Yogic philosophy of ancient India and refers to the mothering intelligence behind yogic awakening and spiritual maturation (Sovatsky, 1998). It mig ...

Bedsores, also called pressure sores or pressure ulcers, are ulcers (sores) caused by prolonged pressure or rubbing on vulnerable areas of the body, such as bony or cartilaginous areas that are prone to moisture and friction. Decubitus ulcers are pressure ulcers that occur when the patient lies on his or her back for long periods (Wilhelmi and Neumeister, 2005). Examples of areas vulnerable to pressure ulcers include the hips, ankles, heels, elbows, ears, and pressure points on the lower back (near the tail bone, ...

Sternum or breastbone is a long, flat bone located in the center of the thorax (chest). It connects to the rib bones via cartilage, forming the rib cage with them, and thus helps to protect the lungs and heart from physical trauma. The sternum is usually cut open (a sternotomy) to gain access to the thoracic contents when performing cardiothoracic surgery. Sternum - Overview. The sternum (Figs. 1 to 3) is an elongated, flattened bone, forming the middle portion of the anterior wall of the thor ...

The calcaneus is the large bone making up the heel of the human foot or the point of an animal's hock. Calcaneus - Human. It articulates with two other tarsal bones, the talus above and the cuboid toward the midfoot. In addition to receiving the weight of the body with each step, the calcaneus is the anchor for the plantar fascia, which supports the arch of the foot. The posterior-most portion of the calcaneus is the calcaneal tuberosity, a large, non-articulating process that is the i ...

The fibula or calf bone is a bone placed on the lateral side of the tibia, with which it is connected above and below. It is the smaller of the two bones, and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the level of the knee-joint, and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia, and forms ...
