The receptors in the skin, the so-called cutaneous receptors, tell us about temperature (thermoreceptors), pressure, and surface texture (mechanoreceptors), and pain (nociceptors). The receptors in muscles and joints provide information about muscle length, muscle tension, and joint angles. ## Cutaneous Receptors Sensory information from Meissner corpuscles and rapidly adapting afferents leads to adjustment of grip force when objects are lifted. These afferents respond with a brief burst of action potentials when objects move a small distance during the early stages of lifting. In response to: ![Figure 1: Receptors in the human skin](image_link_here) **Figure 1**: Receptors in the human skin: Mechanoreceptors can be free receptors or encapsulated. Examples for free receptors are the hair receptors at the roots of hairs. Encapsulated receptors are the Pacinian corpuscles and the receptors in the glabrous (hairless) skin: Meissner corpuscles, Ruffini corpuscles, and Merkel's disks. ¹ The following description is based on lecture notes from Laszlo Zaborszky, from Rutgers University. #################### File: somatosensory.pdf Page: 2 Context: # Mammalian Muscle Spindle ![Mammalian muscle spindle showing typical position in a muscle](image_url) *Figure 2: Mammalian muscle spindle showing typical position in a muscle (left), neuronal connections in spinal cord (middle) and expanded schematic (right). The spindle is a stretch receptor with its own motor supply consisting of several intrafusal muscle fibres. The sensory endings of a primary (group Ia) afferent and a secondary (group II) afferent coil around the non-contractile central portions of the intrafusal fibres.* Rapidly adapting afferent activity, muscle force increases reflexively until the gripped object no longer moves. Such a rapid response to a tactile stimulus is a clear indication of the role played by somatosensory neurons in motor activity. The slowly adapting **Merkel’s receptors** are responsible for form and texture perception. As would be expected for receptors mediating form perception, Merkel’s receptors are present at high density in the digits and around the mouth (50/mm² of skin surface), at lower density in other glabrous surfaces, and at very low density in hairy skin. This innervations density shrinks progressively with the passage of time so that by the age of 50, the density in human digits is reduced to 10/mm². Unlike rapidly adapting axons, slowly adapting fibers respond not only to the initial indentation of skin, but also to sustained indentation up to several seconds in duration. Activation of the rapidly adapting **Pacinian corpuscles** gives a feeling of vibration, while the slowly adapting **Ruffini corpuscles** respond to the lateral movement or stretching of skin. ## Nociceptors Nociceptors have free nerve endings. Functionally, skin nociceptors are either high-threshold mechanoreceptors or low-threshold nociceptive neurons. Image Analysis: ### Image Analysis: #### 1.

Used for joint position in fingers. | Poly-modal receptors. Poly-modal receptors respond not only to intense mechanical stimuli, but also to heat and to noxious chemicals. These receptors respond to minute punctures of the epithelium, with a response magnitude that depends on the degree of tissue deformation. They also respond to temperatures in the range of 40–60°C, and change their response rates as a linear function of warming (in contrast with the saturating responses displayed by non-noxious thermoreceptors at high temperatures). Pain signals can be separated into individual components, corresponding to different types of nerve fibers used for transmitting these signals. The rapidly transmitting signal, which often has high spatial resolution, is called first pain or cutaneous pricking pain. It is well localized and easily tolerated. The much slower, highly affective component is called second pain or burning pain; it is poorly localized and poorly tolerated. The third or deep pain, arising from viscera, musculature and joints, is also poorly localized, can be chronic and is often associated with referred pain. ## Muscle Spindles Scattered throughout virtually every striated muscle in the body are long, thin, stretch receptors called muscle spindles. They are quite simple in principle, consisting of a few small muscle fibers with a capsule surrounding the middle third of the fibers. These fibers are called intrafusal fibers, in contrast to the ordinary extrafusal fibers. The ends of the intrafusal fibers are attached to extrafusal fibers, so whenever the muscle is stretched, the intrafusal fibers are also #################### File: somatosensory.pdf Page: 4 Context: # From Wikibooks ![Figure 3: Feedback loops for proprioceptive signals for the perception and control of limb movements. Arrows indicate excitatory connections; filled circles inhibitory connections.](image_link_placeholder) For more examples of how to use HTML and CSS for paper-based publishing, see [css4.pub](http://css4.pub). --- Muscle spindles are stretched. The central region of each intrafusal fiber has few myofilaments and is non-contractile, but it does have one or more sensory endings applied to it. When the muscle is stretched, the central part of the intrafusal fiber is stretched and each sensory ending fires impulses. Muscle spindles also receive a motor innervation. The large motor neurons that supply extrafusal muscle fibers are called **alpha motor neurons**, while the smaller ones supplying the contractile portions of intrafusal fibers are called **gamma neurons**. Gamma motor neurons can regulate the sensitivity of the muscle spindle so that this sensitivity can be maintained at any given muscle length. ## Joint Receptors The joint receptors are low-threshold mechanoreceptors and have been divided into four groups. They signal different characteristics of joint function (position, movements, direction, and speed of movements). The free receptors or type 4 joint receptors are nociceptors. ########## """QUERY: Im Dokument werden die Gelenkrezeptoren in verschiedene Gruppen eingeteilt, basierend auf ihrer Funktion.

Die Informationen im Dokument beschränken sich auf die Aussage, dass Gelenkrezeptoren niederschwellige Mechanorezeptoren sind, die in vier Gruppen eingeteilt werden und unterschiedliche Eigenschaften der Gelenkfunktion signalisieren. Es wird auch erwähnt, dass die freien Rezeptoren oder Typ-4-Gelenkrezeptoren Nociceptoren sind. Um eine detaillierte Beschreibung jeder Gruppe von Gelenkrezeptoren zu geben, wäre es notwendig, auf zusätzliche Informationsquellen zurückzugreifen, die über den bereitgestellten Kontext hinausgehen. Da dies außerhalb des mir zur Verfügung stehenden Kontextes liegt, empfehle ich, Fachliteratur oder spezialisierte Datenbanken zu konsultieren, um detaillierte Informationen über die verschiedenen Gruppen von Gelenkrezeptoren und ihre Rollen zu erhalten. ================================================== **Elapsed Time: 0.00 seconds** ==================================================
