Root Explanation

Retinula is derived from the Latin root "retina" (meaning net or network) and the diminutive suffix "-ula" (meaning small). The term refers to a small net-like structure, particularly in the context of biology, where it describes a small part of the retina or a similar structure in invertebrates.

Memory Tip

Think of a 'small net' ('retina' means net and '-ula' means small) to remember that 'retinula' refers to a small net-like structure.
