Final answer:
The anatomical term for club-like structures that surround the lens nucleus like a crown are called ciliary processes. They produce aqueous humor in the eye.
Step-by-step explanation:
The club-like structures that lie in the deep cortex and surround the lens nucleus like a crown are called ciliary processes. They are part of the vascular tunic, which is the middle layer of the eye. The ciliary processes are responsible for producing aqueous humor, a watery fluid that fills the anterior chamber of the eye and helps maintain the shape of the eye.
