[The outer epidermal wall of the "sensitive hairs" of dionaea muscipula]
1Botanisches Institut der Universität Bonn, Bonn, Deutschland.
Abstract:
The outer epidermal wall of the podium of the trigger hair of Dionaea muscipula reveals an unusual ultrastructure under the electron microscope. The cuticular layer is penetrated by numerous radially arranged fibrils of about 2 nm in diameter inserting in a fibrillar network beneath the cutinized part of the wall. Both the fibrils and the fibrillar network are heavily stained after treatment with lead citrate. Possibly these specific wall structures make the podium elastic and enable it to undergo repeated bendings.

Accessory Structures of the Skin: Hair and Hair Follicles
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Sensory Functions of the Skin
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
