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]
Pedicel (antenna), the second segment of the antenna in the class Insecta, where the Johnston's organ is found Pedicel or petiole (insect) , the stem formed by a restricted abdominal segment which connects the thorax with the gaster (the remaining abdominal segments) in the suborder Apocrita
Johnston's organ is a collection of sensory cells found in the pedicel (the second segment) of the antennae in the class Insecta. [2] Johnston's organ detects motion in the flagellum (third and typically final antennal segment). It consists of scolopidia arrayed in a bowl shape, each of which contains a mechanosensory chordotonal neuron.
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]
[2] The arrangement of the floral parts on the axis, the presence or absence of one or more floral parts, the size, the pigmentation and the relative arrangement of the floral parts are responsible for the existence of a great variety of flower types. Such diversity is particularly important in phylogenetic and taxonomic studies of angiosperms.
Receptacle – the end of the pedicel that joins to the flower were the different parts of the flower are joined; also called the torus. In Asteraceae, the top of the pedicel upon which the flowers are joined. Seed – Sepal – Antipetalous – when the stamens number the same as, and are arranged opposite, the corolla segments; e.g. Primula.
Pedicel or petiolus: The narrow connection between the cephalothorax and abdomen [22] Pedipalp (plural pedipalps or pedipalpi; also called just palp): The second appendage of the cephalothorax in front of the first leg; bears the palpal bulb in male spiders; [ 10 ] see segments , see also Pedipalp
