A mechanoreceptor, also called mechanoceptor, is a sensory receptor that responds to mechanical pressure or distortion. Mechanoreceptors are innervated by sensory neurons that convert mechanical pressure into electrical signals that, in animals, are sent to the central nervous system.
A thoracic vertebra. (Superior labeled at top; inferior labeled at bottom.) The articular process or zygapophysis (Greek: ζυγόν, romanized: zugón, lit. ' yoke ' + apophysis) of a vertebra is a projection of the vertebra that serves the purpose of fitting with an adjacent vertebra. The actual region of contact is called the articular facet.
In anatomy, Luschka's joints (also called uncovertebral joints, neurocentral joints) [1] are formed between uncinate process or "uncus" below and uncovertebral articulation above. [2] They are located in the cervical region of the vertebral column from C3 to C7. [3] Two lips project upward from the superior surface of the vertebral body below ...
In 1889, Alfred Goldscheider suggested a classification of kinaesthesia into three types: muscle, tendon, and articular sensitivity. [69] In 1906, the term proprio-ception (and also intero-ception and extero-ception) is attested in a publication by Charles Scott Sherrington involving receptors. [70] He explains the terminology as follows: [71]
The facet joint is the joint between the inferior articular process (labeled at bottom) and the superior articular process (labeled at top) of the subsequent vertebra. The facet joints (also zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae.
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
In order for mechanical signals to be sensed, there need to be mechanoreceptors on the surface of chondrocytes. Candidates for chondrocyte mechanoreceptors include stretch-activated ion channels (SAC), [27] the hyaluronan receptor CD44, annexin V (a collagen type II receptor), [28] and integrin receptors (of which there exist several types on ...
articulatio atlantoaxialis mediana, articulatio atlantoaxialis lateralis. MeSH. D001268. FMA. 25524. Anatomical terminology. [edit on Wikidata] The atlanto-axial joint is a joint in the upper part of the neck between the atlas bone and the axis bone, which are the first and second cervical vertebrae. It is a pivot joint.
