Term
|
Definition
| the response of the effector to stimulation by the motor neuron of the reflex of the reflex arc |
|
|
Term
| desccribe the difference between a somatic and visceral reflex |
|
Definition
reflex are rapid involuntary motor responses
the name of the reflex tells us where they occur and what job
*a somatic reflex is a contraction of the skeletal muscle,
* if the motor response involves the response of smooth muscle cardio muscle or glands it is automatic (visceral) reflex |

Term
| difference between cranial and spinal reflex |
|
Definition
reflexes mediated by cranial nerves are cranial reflexes (brain stem)
spinal reflexes are reflexes mediated by the spinal nerves and spinal cord |
|
|
Term
| describe the difference between ipsilateral and contralateral reflex arc |
|
Definition
reflex arcs involve sensory receptors, sensory nerve fibers, motor neurons and effectors----
ipsilateral occur only on one side of the body... whereas contralateral occur on one side of the body with the exception of motor neurons and effectors occuring on the opposite side |
