The plural form of epiphysis is epiphyses. (Anatomy) Also called: epiphysis cerebri the technical name for pineal gland. (Anatomy) the end of a long bone, initially separated from the shaft (diaphysis) by a section of cartilage that eventually ossifies so that the two portions fuse together. READ: Does a PJ bass sound like a Jazz bass? What does epiphysis mean in anatomy? The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone.
CONARIUM OR EPIPHYSIS CEREBRI FULL
What is meant by epiphysis?Įpiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. Externally it has a thin layer of compact bone, while internally the bone is cancellous. The distal tibia, fibula, ulna, and radius are the most common sites affected.ĮPIPHYSIS (end) (a), EPIPHYSIAL LINE (a) – purple The epiphysis is the end of a long bone. Because the epiphysis is responsible for longitudinal bone growth, injury disrupting vascular supply to the epiphysis or metaphysis affects bone growth. The epiphysis is a common site of injury in the growing skeleton. Examples of traction epiphyses are tubercles of the humerus (greater tubercle and lesser tubercle), and trochanters of the femur (greater and lesser). the head of the femur, part of the hip joint complex). Pressure epiphysis: The region of the long bone that forms the joint is a pressure epiphysis (e.g. READ: Why you should stop playing clash of clans? The distal epiphysis is also is covered in articular cartilage, enabling bones to move at the joints without grinding on each other. The distal epiphysis is the rounded part of the bone found at the end of the diaphysis that is pointing away from the center of the body. These types of fused bones are called atavistic, e.g., the coracoid process of the scapula, which has been fused in humans, but is separate in four-legged animals.
What is atavistic epiphysis?Ītavistic epiphysis: A bone that is independent phylogenetically but is now fused with another bone. The distal epiphysis is located at the end of the long bone that is farther away from the center of the body. The proximal epiphysis is the end of the long bone closest to the center of the body. Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate). The epiphysis is the rounded end of a long bone, at its joint with adjacent bone(s). The arterial supply obtained through several groups of pineal arteries stemming mainly from the posteromedial choroidal artery 3).READ: Is Giganotosaurus the king of the dinosaurs? What is epiphysis and metaphysis?
The other arteries included the medial pineal artery from the posterior circulation and the rostral pineal artery mainly from the anterior circulation. The main artery of the PG was the lateral pineal artery, and it originated from the posterior circulation.
Studies regarding the arterial vascularization of the PG have been carried out on humans by Duvernoy The pineal gland (PG) is arterialized by branches deriving from the anterior cerebral artery and posterior cerebral artery. This emphasizes the necessity of showing these feeding arteries and the relationship between them in this clinically and surgically important area The lack of knowledge in this field contributes to the likelihood of complications occurring during surgery in this area. The arterial vascularization of the pineal gland (PG) remains a debatable subject.
