Short vs long reflexes
SpletFigure 15.8 Short and Long Reflexes Sensory input can stimulate either a short or a long reflex. A sensory neuron can project to the CNS or to an autonomic ganglion. The short reflex involves the direct stimulation of a postganglionic fiber by the sensory neuron, whereas the long reflex involves integration in the spinal cord or brain. SpletA short list of signal molecules known to modulate presynaptic vagal afferent activity ... which is an important cross road for the information signaled from the gut to CNS required to control gut functions via long vagovagal reflexes (Figure 4). Information conveyed to brainstem by afferent nerves terminate in the NTS, which is adjacent to ...

Splet26. sep. 2024 · Two distinct behaviors have been identified for these rapid motor responses, often called long-latency reflexes. The first is to maintain limb stability by opposing … SpletProbably the best-known reflex is the pupillary light reflex. If a light is flashed near one eye, the pupils of both eyes contract. Light is the stimulus, impulses reach the brain via the optic nerve, and the response is conveyed to the pupillary musculature by autonomic nerves that supply the eye. Reflexes are there to protect our body parts.
Splet06. dec. 2024 · Reflexes allow reaction to a stimulus more quickly than would be possible if conscious thought were involved. A reflex can be described as a stimulus-response cycle. Most reflexes involve the brainstem or the spinal cord and do not require interaction from higher brain centers. The muscle stretch reflexes are the simplest reflexes. Splet30. nov. 2010 · I believe a short reflex is when one is partially aroused, as during a bumpy car ride or Kate Winslet's nude scene in Titanic. A long reflex is when the member …

Splet01. jul. 1987 · Oropharyngeal-stimulated responses are reliably initiated by the taste and smell of food. These gastrointestinal reflexes, often referred to as anticipatory or cephalic phase responses, are mediated by the autonomic nervous system and are believed to be independent of the postabsorptive effects of ingested nutrients. tina smith for minnesotaThe short reflex involves the direct stimulation of a postganglionic fiber by the sensory neuron, whereas the long reflex involves integration in the spinal cord or brain. The difference between short and long reflexes is in the involvement of the CNS.
