A peduncle is an elongated stalk of tissue. Sessility is the state of not having a peduncle; a sessile mass or structure lacks a stalk.[1]
In medicine, a mass such as a cyst or polyp is said to be pedunculated if it is supported by a peduncle.[2]
There are in total three types of peduncles in the cerebellum of the human brain, known as superior cerebellar peduncle, middle cerebellar peduncle, and inferior cerebellar peduncle.[3]
Pedunculated eyes are also the defining attribute of the stylophthalmine trait found in certain fish larvae. The caudal peduncle is a slightly narrowed part of a fish where the caudal fin meets the spine.[4]
