"Lamellophone" Natural Recordings by Native Speakers
A lamellophone is a type of musical instrument that produces sound when various objects called "lamellae" are struck, typically with fingers or a mallet. The lamellae are usually arranged vertically on a flat surface, and when struck, they produce a percussive sound, often with a bright, metallic quality. Examples of lamellophones include the kalimba, mbira, and thumb piano. The instrument is popular in many African and Asian cultures, and is often used in traditional and folk music.
Lamellipodia is a type of cellular structure that is found on the surface of certain animal cells, including fibroblasts, epithelial cells, and neutrophils. It is a sheet-like extension of the cell membrane that is involved in cell migration, adhesion, and signaling. Lamellipodia are formed when actin filaments and microtubules interact with the cell membrane, creating a dynamic and flexible structure that can change shape and move in response to external cues. They play a critical role in various cellular processes, including wound healing, tissue repair, and immune responses.
Lamentable refers to something that is unfortunate, regrettable, or distressing. It can also describe something that is depressing, sad, or miserable. The word often has a sense of disappointment or disgust, and is often used to describe something that is undesirable or unpleasant. For example, "The news about the devastating hurricane was lamentable and heartbreaking."
