"Cephalexin" Natural Recordings by Native Speakers
Cephalexin is a type of antibiotic, specifically a first-generation cephalosporin. It is used to treat infections caused by susceptible bacteria, such as bronchitis, pneumonia, and skin infections. It works by interfering with the ability of bacteria to form cell walls, ultimately killing the bacteria.
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.
Cephalaspidomorphi is a taxonomic group that refers to a set of ancient fish-like vertebrates that lived during the Paleozoic Era, around 450-360 million years ago. These fish are characterized by having a headshield (cephalaspid) that covers the skull and often has a distinctive capsule-like shape. They were likely related to the origins of the modern group of fish, but have since become extinct.
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.
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.
Cephalgia is a medical term that refers to a headache or a severe pain in the head. It can be caused by a variety of factors, including tension, migraines, sinus pressure, and even stress. The word "cephal-" comes from the Greek word "kephale", meaning "head", and "-algia" comes from the Greek word "algos", meaning "pain". So, cephalgia literally means "pain in the head".
A cephalhaematoma is a type of bleb or bump on the scalp that occurs when blood collects under the falx cerebri, a diploid membrane in the brain, usually as a result of trauma or injury, such as a blow to the head. It is typically seen in newborns, particularly those who have undergone forceps delivery or been subjected to other physical pressure while being born. The bump can range in size from a small soft spot to a large bulge, and it usually resolves on its own within a few weeks or months.
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.
Cephalic refers to something related to the head or brain. It can also describe a shape or form that is rounded or bulbous, often in reference to the shape of the human head. In medical contexts, cephalic may refer to the cranial region or the skull.
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.
Cephalitis is an inflammation of the brain or its covering, the meninges. It can be caused by various factors such as infection, trauma, or autoimmune disorders, and can lead to symptoms like fever, headache, and seizures.
