Involve muscle groups and related joints, bones, tendons, ligaments and fascia and are referred to as inter-joint reflex movements.Įxamples: Foot grasp reflex and Babinski reflex. Involve a single muscle and related joints, bones, tendons, ligaments and Fascia and are referred to as reflex actions.Įxamples: Knee jerk reflex and withdrawal reflex. Summarized below are the basic parameters used to define each of the structural reflex variations along with a table outlining the various ways in which less complex reflexes can function – independently and or as subordinate components of related, more complex innate reflexes, acquired reflexes, or learned reflexive responses. This structural characterization can be applied to all motor movement reflexes whether they are lifelong, primary, innate or acquired. Somatic reflex categories include motor reflex actions, movements, patterns, and schemes.

Motor movement reflexes can be categorized according to the number and combination of muscles, joints, and limbs involved in executing a particular motor response. As each reflexive somatic response emerges it qualitatively and quantitatively expands our ability to interact more efficiently and effectively with the world around us, expanding our repertoire to include simple to complex motor movements. The somatic system works with the central nervous system to moderate and coordinate innate and acquired reflexes as well as learned reflexive responses.
