A reflex arc involves the following components:
An effector is at the end of a reflex arc as it is the muscle or gland that 'does' the reflex. What the effector does is the outcome of the reflex arc.
PNS delivers motor response from CNS to effectors...
Yes animals have reflex arc
A reflex arc does not pass through the brain. The somatic reflex arc and autonomic reflex arc are two types.
Reflex arc is the path of reflex action. Reflex Action is action it self
Hormones have nothing to do in reflex arc.
delivery of sensory information.....
Muscles and glands are the possible effectors of a reflex arc
The reflex arc is the nerve pathway that the signal follows. For example, the knee jerk reflex arc has a stimulus going to an interneuron in the spine and a motor neuron completes the arc by causing the knee to jerk. A reflex is just the action itself.
