receptors estereoceptors and proprioceptors

Tactile and mechanoreceptors, especially on the feet, contribute to proprioception, especially conscious proprioception, while hair cells in the vestibular apparatus of the inner ear supply information about head position and movement.

It also indicates where various parts of the body are located in relation to each other. Proprioception indicates whether and how joints, muscles and tendons are moving based on input from muscle spindles, Golgi tendon organs and joint receptors. Proprioception ( proprius – L = one’s own, capere – L = to receive) is the sense of the relative position of parts of the body. Spinocuneocerebellar and cranial spinocerebellar tracts (from the cranial half of body)ĭF = dorsal funiculus, LF = lateral funiculus, VF = ventral funiculus. Subconscious proprioception and cerebellar inputĭorsal and ventral spinocerebellar tract (from the caudal half of body) Spinothalamic tract (skin, viscera and body)ĭiscriminative touch, pressure and conscious proprioceptionįasciculus cuneatus (from the body cranial to T8)įasciculus gracilis and dorsal spinocerebellar tract (from the body caudal to T8)

Table 6.1 Ascending tracts, their functions and locations in the spinal cordįasciculus gracilis and fasciculus cuneatus (skin) Sensory modalities that do not fit this three-stage structure include olfaction, vision and some nociceptive pathways (Table 6.1).

Thalamocortical projection to the somatosensory cortex of the cerebrum. It eventually joins, or runs adjacent to, a pathway called the medial lemniscus through the brainstem to the thalamus ģ. A relay section in the CNS comprising a central pathway that has one, or more, synapses in specific nuclei. A receptor and an axon with a cell body in the ganglion in the PNS Ģ.
