Definition: The middle layer of cells in an embryo that develops into various tissues and organs, including muscles, bones, and the circulatory system.

Example: During embryonic development, the mesoderm forms important structures such as the heart and muscles.

Definition: Relating to the middle layer of cells in an embryo that develops into muscles, bones, and other tissues.

Example: The mesodermal layer is crucial for the development of the circulatory system.

Definition: A type of cell in early embryonic development that is larger than a micromere but smaller than a macromere, often found in the middle layer of the mesoderm in vertebrate embryos.

Example: During the development of the embryo, the mesomere plays a crucial role in forming the excretory tissues.

Definition: Relating to a body type that is muscular and well-built, often characterized by a strong physique.

Example: He has a mesomorphic body type, which makes it easier for him to gain muscle.

Definition: A type of subatomic particle made of a quark and an antiquark, which participates in strong interactions and has a mass between leptons and baryons.

Example: The physicists studied the properties of mesons to understand the strong force better.

Definition: The second of the three organs that help remove waste in the body of a developing vertebrate, which works as a kidney in fish and amphibians but is replaced by another organ in more advanced animals.

Example: In fish and amphibians, the mesonephros serves as the main kidney during their development.

Definition: The upper boundary of the atmosphere where the temperature is at its lowest point.

Example: The mesopause is located between the mesosphere and the thermosphere.

Definition: The layer of tissue in a leaf where photosynthesis occurs, found between the outer layers of the leaf.

Example: The mesophyll is crucial for the plant's ability to convert sunlight into energy.

Definition: Referring to something that is of medium size, typically between small-scale and large-scale, often used in contexts like meteorology to describe phenomena that cover a range of distances.

Example: The mesoscale weather patterns can significantly affect local climates.

Definition: A size that is between small and large, often used to describe weather patterns or phenomena that are not too big or too small.

Example: The meteorologist studied the mesoscale weather systems to predict local storms.

Definition: The layer of the Earth's atmosphere that is located above the stratosphere and below the thermosphere, where temperatures drop as altitude increases.

Example: The mesosphere is where meteors burn up upon entering the Earth's atmosphere.
