Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin pediculus, meaning "little foot". [2] The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. [3] A pedicel may be associated with a bract or bracts. [4]

The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum, which often comprises many units known as flagellomeres. [10] The pedicel (the second segment) contains the Johnston's organ which is a collection of sensory cells. [11]
The petiole is occasionally called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; [1] [2] while in arachnology, 'pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders.
In deliberate or suicidal hanging, asphyxia is much more likely to be the cause of death due to associated prevertebral swelling. A common sign is a constricted pupil ( Horner's syndrome ) on the ipsilateral side due to loss of sympathetic innervation to the eye, caused by damage to the sympathetic trunk in the neck.

According to Guinness the pedicel of the H. whipplei inflorescence can grow up to ten inches (25 cm) a day towards an eventual height of 11ft 11in (3.65 meters) [6] The plant takes several (usually 5+) years to reach maturity and flower, doing so in April–May, [5] at which point it usually dies.
