  • In botany, a peduncle (botany) is a stalk supporting an inflorescence.
  • In anatomy, a cerebral peduncle is a band of neurons, resembling a stalk, which connect varied parts of the brain.
  • In insect brains, the peduncle connects the lobes of the mushroom bodies to its calyx.
  • In zoology, a peduncle (zoology) is a stem, through which a mass of tissue is attached to a body.
  • In fish anatomy, the caudal peduncle is the narrow part of the body to which the tail attaches.
  • In arthropod morphology, a peduncle (arthropods) is the base segments of an antenna.
In botany, a peduncle is a stalk supporting an inflorescence, or after fecundation a fruit.

The peduncle has the structure of a stem. It is usually green, and without leaves. It can however sometimes support small leaves, or be colored.

The mushroom bodies or corpora pedunculata are a pair of structures in the brain of insects and other arthropods. They are usually described as neuropils, i.e. as dense networks of neurons and glia.

Biological tissue is a collection of interconnected cells that perform a similar function within an organism.

The study of tissue is known as histology, or, in connection with disease, histopathology.

Antennae (singular antenna) are paired appendages connected to the front-most segments of arthropods. In crustaceans, they are biramous and present on the first two segments of the head, with the smaller pair known as antennules.
