(contralateral / ipsilateral), and 9. parasympathetic /sympathetic)Explanation / Answer
1) The neural pathway that mediates a reflex is called REFLEX ARC
- It consist of afferent and efferent nerve fibers, interneurons , receptor and effector.
2) The reflex is unleared and motor response to stimuli.
3) On the basis of primary location, reflexes are classified into :
a . Cranial relex
b. Spinal reflex
4) If the effector is eliciting response in skeletol muscle, the reflex is classified as Somatic.
5) The site of stimulus detection is called Receptor.
6) The knee jerk reflex is classified as Spinal , somatic, ipsilatateral and monosynaptic reflex.
7) The Achilles reflex can be classified as Spinal , somatic , ipsilatateral and monosynaptic reflex.
8) The pupillary light relex is classified as Cranial, autonomic, ipsilateral and polysynaptic.
- If the light enetrs in same eye it is ipsilateral and if the light enetrs in opposite eye it is contralateral. So it can be said that pupillay light reflex is both ipsilateral and contralateral.
9) Pupillary constriction is mediated by the Parasympathetic divison of the autonomic nervous system.
