Peduncle (anatomy)
In medicine and zoology, a peduncle is an elongated stalk of tissue. A mass such as a cyst or polyp is said to be pedunculated if it is supported by a peduncle, in contrast with a sessile mass which lacks a stalk.
There are three types of peduncles in the cerebellum. They are known as superior cerebellar peduncle, middle cerebellar peduncle, and inferior cerebellar peduncle.
Pedunculated eyes are also the defining attribute of the Stylophthalmine trait found in certain fish larvae.
