Antennae
Antennae (Medicine)
Antennae (pronounced: an-ten-ee) is a term used in the medical field, particularly in the study of Genetics and Cell Biology.
Etymology
The term "antennae" is derived from the Latin word antenna, which originally referred to the mast or pole on a ship. In the context of biology and medicine, it is used metaphorically to describe structures that protrude from a cell and function in signal reception, similar to the way an antenna on a ship or a radio receives signals.
Definition
In medicine, "antennae" refers to the hair-like structures found on the surface of some cells, such as Cilia and Flagella. These structures are involved in various cellular functions, including movement, sensory perception, and signal transduction.
Related Terms
- Cilia: Microscopic, hair-like structures present on the surface of all mammalian cells. They are primarily responsible for locomotion and play a significant role in human sensory processes such as hearing and smell.
- Flagella: A whip-like structure that allows a cell to move. They are found in all three domains of life: bacteria, archaea, and eukaryotes.
- Signal Transduction: The process by which a chemical or physical signal is transmitted through a cell as a series of molecular events, most commonly protein phosphorylation catalyzed by protein kinases, which ultimately results in a cellular response.
- Cell Biology: A branch of biology that studies the different structures and functions of the cell and focuses mainly on the idea of the cell as the basic unit of life.
- Genetics: The study of genes, genetic variation, and heredity in living organisms.
