Definition: Euplectroscelis is a type of marine invertebrate that has both an exoskeleton and a pleuronectoderm, making it unique among other eudicotinids. This structure allows for rapid movement and movement through water without the need for a swim bladder or a shell.
Definition: Reticuloendotheliosis is a rare, genetic disorder characterized by an abnormal growth pattern in the brain and spinal cord that can lead to severe neurological issues and death if left untreated. It primarily affects individuals with a mutation in the PAX7 gene, which is involved in neuroectodermal development. This condition usually starts before birth or during pregnancy and is often diagnosed at birth due to symptoms like seizures, difficulty breathing, or increased sensitivity to light.
Definition: Ceratoserolis is a type of bone tissue composed primarily of calcium carbonate, which forms a hard, fibrous structure in the mesoderm and neuroectodermal regions of the body. It plays an essential role in supporting skeletal structures during development and maintaining homeostasis through its function as a reservoir for calcium ions.
Definition: Ectadoderus is a large, complex order of extinct mammals that lived during the Late Cretaceous period about 68 million years ago in Europe and North Africa. They were known for their large brain size, which allowed them to adapt to environments with varying temperatures and pressures. The term "ectadoderus" refers to this group of animals because they share a common ancestor with modern mammals but are characterized by their larger brains, or ectoderm, which is more complex than
Definition: Caenogenesis is a biological process that occurs during the formation of new cells in the developing embryo, such as the placenta. It involves the differentiation of mesoderm cells into extraembolic mesodermal (EM) cells, which then differentiate into ectoderm cells to form the final structure of the embryo.
Definition: Ciliated is a term used in medicine to describe cells that are involved in the process of cell-cell communication. These cells, also known as endoderm cells or ectodermal cells, play a crucial role in the development and maintenance of the epithelial lining of the urinary tract by secreting mucus. Cilia, which are tiny hair-like structures, are responsible for this process. The term "ciliated" is often used to describe these cells because they are typically found under the surface
Definition: The term "tropheotheca" refers to a type of organ that is found in certain animals, specifically in the reptiles. These organs are called trohectodes and play an important role in their development and survival. They are characterized by their shape resembling a triangular prism or cylinder. The presence of these organs can be seen in various species of reptiles, including snakes, lizards, and turtles.
Definition: The term "subectodermic" is a term used in medicine and dermatology. It refers to a type of skin cell that develops from the dermis (the outermost layer of the skin) and can be found on various parts of the body, including the scalp, eyebrows, lips, and even the nails. Subectodermic cells are responsible for the production of hair follicles, which are important for hair growth and maintenance in the human body.
Definition: The term "subectodermal" refers to a specific area within the skin, which is often referred to as "the innermost layer of the epidermis." This layer is composed primarily of keratinocytes and contains many hair follicles, sweat glands, and blood vessels. The subectodermal layer is responsible for the function of the skin's barrier against external factors such as dust, pollution, and heat, and it also plays a role in the development of the epidermis
Definition: Spermatogenesis is a biological process in which sperm cells develop intoζηηη²Ύε (sperm)γ It occurs during the male reproductive cycle, typically between 10 and 14 years of age. Spermatogenesis involves several stages including:
1.
Gynostery
: This stage marks the beginning of spermatogenesis. In this stage, germ cells (male gametes) begin to form into sperm.
2.
Ectoderm
: The outermost layer of
