"Cephalectomy" Natural Recordings by Native Speakers
Cephalectomy is a rare surgical procedure in which the cranium, or skull, is removed. It is typically performed in cases where the patient has a large or abnormal skull that is causing significant medical problems, such as pressure on the brain, difficulty walking or standing, or facial paralysis. The procedure is usually performed under general anesthesia and involves the removal of the entire skull, which is then replaced with a custom-made prosthesis or implant.
Cephalaspid refers to an ancient group of extinct fish-like animals that lived during the Silurian and Devonian periods, around 440-360 million years ago. They were characterized by their unique skull structure, which had a pair of large, flat bones on either side of the head that were covered in denticles, similar to the scales of a shark. The name "cephalaspid" comes from the Greek words "kephale," meaning "head," and "aspis," meaning "shield," likely due to the distinctive shape of their skull.
Cephalaspida is a subclass of marine snails, belonging to the class Gastropoda. It is characterized by having no protective mantle skirt on their body. They are often referred to as "primitive" or "lower" snails, suggesting an evolutionary relationship with more ancient species.
Cephalaspidea is a taxonomic subgroup of sea hares, a type of marine snail that belongs to the order Nudibranchia. The name Cephalaspidea comes from the Greek words "kephale" meaning "head" and "aspis" meaning "aspis" or "shield", likely referring to the snail's distinctive head shape.
Cephalaspis refers to a genus of ancient sea creatures, specifically a type of extinct brachiopod, a group of marine animals that were characterized by their shell and feeding organ.
Cephalate refers to something that has a head or a terminal part. In biology, it is used to describe the head or anterior part of an organism, such as a cephalate sperm cell. In anatomy, it can also refer to the anterior or superior part of a bone or other structure. In general, the term "cephalate" is used to describe the terminal or head-like part of something.
Cephalate refers to something that has a head or a rounded mass at one end, such as a cephalated egg, which has a rounded head or "head" end.
A cephalhematoma is a type of head injury that occurs when blood accumulates between the skull and the scalp. It is typically seen in newborn babies, particularly those who have been delivered vaginally, and is often caused by a forceful delivery or other trauma to the head. A cephalhematoma is characterized by a bulge or swelling on the forehead or scalp, which can be painful for the baby and may require medical treatment.
Cephalin is a type of phospholipid, which is a naturally occurring fatty compound. It is a major component of cephalin letter complexes, which are a kind of lipid bilayer that forms the outer layer of many cells, including red and white blood cells. Cephalin has important roles in cell structure, function, and signaling, and is involved in various physiological processes such as cell-cell interactions, cell signaling, and regulation of cell growth and development.
Cephalisation refers to the process by which some animals, particularly vertebrates, have evolved to develop a larger brain-to-body mass ratio, accompanied by an increase in cognitive abilities, particularly in the development of complex behaviors and socialization. This process is often associated with the evolution of humans and some other primates.
Cephalised refers to the process of turning the head or face towards something, or being directed towards a particular point or direction. It can also refer to the positioning of something, such as a part or object, in a specific location or direction, often in a precise or deliberate manner.
