Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung; Hoffmann's reflex — also known as the finger flexor reflex; middle finger and thumb response. Test can indicate both neurological damage and nerve regeneration; often combined with the Babinski reflex test. Jaw jerk reflex
This is observed in reflexes such as the startle reflex, which provides an automatic response to an unexpected stimulus, and the feline righting reflex, which reorients a cat's body when falling to ensure safe landing. The simplest type of reflex, a short-latency reflex, has a single synapse, or junction, in the signaling pathway. [7]
Usually the onset of the startle response is a startle reflex reaction. The startle reflex is a brainstem reflectory reaction (reflex) that serves to protect vulnerable parts, such as the back of the neck (whole-body startle) and the eyes (eyeblink) and facilitates escape from sudden stimuli. It is found across many different species ...
The patellar reflex (knee jerk) is an example of the stretch reflex and it is used to determine the sensitivity of the stretch reflex. Reflexes can be tested as part of a neurological examination, often if there is an injury to the central nervous system. To test the reflex, the muscle should be in a neutral position.
However, there is some evidence to suggest that the gain or magnitude of these reflexes can be adjusted by context and experience. [29] Polysynaptic reflexes or long-loop reflexes are reflex arcs which involve more than a single synaptic connection in the spinal cord. These loops may include cortical regions of the brain as well, and are thus ...
Reflexes can be very simple, as in the monosynaptic reflex, which only contains one synapse, or more complicated, as in the polysynaptic reflex, which involves more than one synapse. The knee jerk reflex is a common example of a monosynaptic reflex when one is looking at the quadriceps motor response of kicking your leg out.
An example of this is when a person steps on a nail: The leg that is stepping on the nail pulls away, while the other leg takes the weight of the whole body. [4] The crossed extensor reflex is contralateral, meaning the reflex occurs on the opposite side of the body from the stimulus.
Reflex circuits vary in complexity—the simplest spinal reflexes are mediated by a two-element chain, of which in the human body there is only one, also called a monosynaptic reflex (there is only one synapse between the two neurones taking part in the arc: sensory and motor). The singular example of a monosynaptic reflex is the patellar reflex.
