WebJun 26, 2024 · First part: cuticular mechanoreceptors. Alike all arthropods, insects have an external skeleton, the exoskeleton, consisting of chitin and forming the cuticle (lire th article).Its insulating properties imply that the cuticle creates a barrier to the reception of stimuli from the external environment to the internal physiological environment. WebOct 24, 2016 · As in vertebrates, the different types of insect mechanoreceptors are traditionally divided into two functional groups: exteroceptors and proprioceptors. Exteroceptors directly detect mechanical forces generated in the external world, while proprioceptors detect the position or movement of body parts.
WebDec 7, 1998 · This paper reviews the structure and function of insect mechanoreceptors with respect to their cellular, subcellular, and cuticular organization. Four types are described and their function is discussed: 1, the bristles; 2, the trichobothria; 3, the campaniform sensilla; and 4, the scolopidia. Usually, bristles respond to touch, trichobothria ... WebInsects placed on a surface that provides a temperature gradient (warmer at one end and cooler at the other) often congregate in a narrow band at a particular temperature, providing behavioral evidence of sensitive thermoreception. Honeybees ( Apis mellifera) placed on such gradients normally choose a temperature range of 34 ± 2 °C (93 ± 3.6 °F).
WebJan 1, 2009 · Mechanoreception is the sense that allows insects to detect their external and internal mechanical environments, including physical orientation, acceleration, vibration, … WebJul 3, 2024 · These are highly sensitive mechanoreceptors embedded in the insect exoskeleton and measuring cuticular strain (Fig. 2c). Though not quite applying the natural way of stimulation, these authors studied the time-dependent mechanical coupling of the stimulus by indenting the sensillum cap at various frequencies between 3 mHz and 100 Hz.
Insect and arthropod mechanoreceptors include: • Campaniform sensilla: Small domes in the exoskeleton that are distributed all along the insect's body. These cells are thought to detect mechanical load as resistance to muscle contraction, similar to the mammalian Golgi tendon organs. • Hair plates: Sensory neurons that innervate hairs that are found in the folds of insect joints. These hairs are deflected when one body segment mo…
