DefinitionIntroductory
What is the characteristic arrangement of microtubules found in cilia as shown in the electron micrograph?
The characteristic arrangement of microtubules found in cilia is the "9 + 2" arrangement.
Cilia have a distinct "9 + 2" arrangement of microtubules, which is visible in electron micrographs. This arrangement consists of nine pairs of microtubules forming a ring around two central single microtubules. This structure is crucial for the function of cilia in movement and sensory roles.
Key points
- Cilia have a "9 + 2" microtubule arrangement.
- This structure is visible in electron micrographs.
- The arrangement consists of nine pairs of microtubules surrounding two central ones.
- This arrangement is essential for ciliary movement and function.
