317a And 317b Mummies
Mummies 317a and 317b were the infant daughters of the Eighteenth Dynasty pharaoh Tutankhamun; their mother is presumed to be his only known wife, Ankhesenamun, who has been tentatively identified as the mummy KV21A. They were buried in their father's tomb, which was discovered by Howard Carter in 1922. Both babies are unnamed, as the coffin inscriptions call them only "the Osiris" (the deceased), so they are known instead by the numbers assigned by Carter during his excavation. They have been examined several times since their discovery, and 317b has been diagnosed with conditions such as Sprengel's deformity and spina bifida, although more recent CT analysis has refuted this. The mummy referred to as 317a is of a girl who was born prematurely at 5–6 months' gestation, and mummy 317b is that of a girl born at or near full term. No cause of death could be determined for either child. Discovery The mummies were buried in Tutankhamun's tomb, in the north-eastern corner o ...

Cairo University
Cairo University ( ar, جامعة القاهرة, Jāmi‘a al-Qāhira), also known as the Egyptian University from 1908 to 1940, and King Fuad I University and Fu'ād al-Awwal University from 1940 to 1952, is Egypt's premier public university. Its main campus is in Giza, immediately across the Nile from Cairo. It was founded on 21 December 1908;"Brief history and development of Cairo University." Cairo University Faculty of Engineering. http://www.eng.cu.edu.eg/CUFE/History/CairoUniversityShortNote/tabid/81/language/en-US/Default.aspx however, after being housed in various parts of Cairo, its faculties, beginning with the Faculty of Arts, were established on its current main campus in Giza in October 1929. It is the second oldest institution of higher education in Egypt after Al Azhar University, notwithstanding the pre-existing higher professional schools that later became constituent colleges of the university. It was founded and funded as the Egyptian University by a comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inguinal Ligament
The inguinal ligament (), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: *Psoas major, iliacus, pectineus * Femoral nerve, artery, and vein * Lateral cutaneous nerve of thigh *Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint of ...

Fontanelle
A fontanelle (or fontanel) (colloquially, soft spot) is an anatomical feature of the infant human skull comprising soft membranous gaps ( sutures) between the cranial bones that make up the calvaria of a fetus or an infant. Fontanelles allow for stretching and deformation of the neurocranium both during birth and later as the brain expands faster than the surrounding bone can grow. Premature complete ossification of the sutures is called craniosynostosis. After infancy, the anterior fontanelle is known as the bregma. Structure An infant's skull consists of five main bones: two frontal bones, two parietal bones, and one occipital bone. These are joined by fibrous sutures, which allow movement that facilitates childbirth and brain growth. * Posterior fontanelle is triangle-shaped. It lies at the junction between the sagittal suture and lambdoid suture. At birth, the skull features a small posterior fontanelle with an open area covered by a tough membrane, where the two ...

KV54
Tomb KV54 is located in the Valley of the Kings, in Egypt. It was originally excavated by Edward R. Ayrton on behalf of the American lawyer Theodore M. Davis, who funded the work. History Not so much a tomb but a small pit located near the tomb of Seti I, it contained about a dozen large sealed storage jars. Within the jars were contained assorted equipment and objects that had been carefully packed. It contained pottery, dishes, bags of natron, animal bones, floral collars and linen containing text dated to the final years of the then (1907) little-known pharaoh Tutankhamun. In 1909, Davis donated the finds he was allowed to take out of Egypt (the contents of six of the storage jars), which were of little intrinsic value, to the Metropolitan Museum of Art in New York City, where they currently reside and are on display. Davis declared to the press that he had found the tomb of Tutankhamun, and he published his findings in a book called The ''Tombs of Harmhabi and Touatankhamanou ...

Humerus
The humerus (; ) is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes ( trochlea & capitulum), and 3 fossae ( radial fossa, coronoid fossa, and olecranon fossa). As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its surgical neck due to its tendency to fracture, thus often becoming the focus of surgeons. Etymology The word "humerus" is derived from la, humerus, umerus meaning upper arm, shoulder, and is linguistically related to Gothic ''ams'' shoulder and Greek ''ōmos''.

Umbilical Cord
In placental mammals, the umbilical cord (also called the navel string, birth cord or ''funiculus umbilicalis'') is a conduit between the developing embryo or fetus and the placenta. During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and (in humans) normally contains two arteries (the umbilical arteries) and one vein (the umbilical vein), buried within Wharton's jelly. The umbilical vein supplies the fetus with oxygenated, nutrient-rich blood from the placenta. Conversely, the fetal heart pumps low-oxygen, nutrient-depleted blood through the umbilical arteries back to the placenta. Structure and development The umbilical cord develops from and contains remnants of the yolk sac and allantois. It forms by the fifth week of development, replacing the yolk sac as the source of nutrients for the embryo. The cord is not directly connected to the mother's circulatory system, but instead joins the placenta, which transfers materi ...

Lanugo
Lanugo is very thin, soft, usually unpigmented, downy hair that is sometimes found on the body of a fetus or newborn. It is the first hair to be produced by the fetal hair follicles, and it usually appears around sixteen weeks of gestation and is abundant by week twenty. It is normally shed before birth, around seven or eight months of gestation, but is sometimes present at birth. It disappears on its own within a few weeks. It is replaced by hair covering the same surfaces, which is called vellus hair. This hair is thinner and more difficult to see. The more visible hair that persists into adulthood is called terminal hair. It forms in specific areas and is hormone-dependent. The term is from the Latin '' lana'', meaning "wool." Humans Fetal development During human development, the lanugo grows on fetuses as a normal part of gestation, but it is usually shed and replaced by vellus hair at about thirty-three to thirty-six weeks of gestational age. As the lanugo is shed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. The time interval of a gestation is called the '' gestation period''. In obstetrics, '' gestational age'' refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. Mammals In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). Humans In humans, pregnancy can be defined clinically or biochemically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonadotropin (hCG) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortise And Tenon
A mortise and tenon (occasionally mortice and tenon) joint connects two pieces of wood or other material. Woodworkers around the world have used it for thousands of years to join pieces of wood, mainly when the adjoining pieces connect at right angles. Mortise and tenon joints are strong and stable joints that can be used in many projects. They furnish a strong outcome and connect by either gluing or locking into place. The mortise and tenon joint also gives an attractive look. One drawback to this joint is the difficulty in making it because of the precise measuring and tight cutting required. In its most basic form, a mortise and tenon joint is both simple and strong. There are many variations of this type of joint, and the basic mortise and tenon has two components: #the mortise hole, and #the tenon tongue. The tenon, formed on the end of a member generally referred to as a rail, fits into a square or rectangular hole cut into the other, corresponding member. The tenon is ...

Djed
The ''djed,'' also ''djt'' ( egy, ḏd 𓊽, Coptic ''jōt'' "pillar", anglicized /dʒɛd/) is one of the more ancient and commonly found symbols in ancient Egyptian religion. It is a pillar-like symbol in Egyptian hieroglyphs representing stability. It is associated with the creator god Ptah and Osiris, the Egyptian god of the afterlife, the underworld, and the dead. It is commonly understood to represent his spine. Myth In the Osiris myth, Osiris was killed by Set by being tricked into a coffin made to fit Osiris exactly. Set then had the coffin with the now deceased Osiris flung into the Nile. The coffin was carried by the Nile to the ocean and on to the city of Byblos in Lebanon. It ran aground and a sacred tree took root and rapidly grew around the coffin, enclosing the coffin within its trunk. The king of the land, intrigued by the tree's quick growth, ordered the tree cut down and installed as a pillar in his palace, unaware that the tree contained Osiris's body. Meanwh ...
