What is the correct order of the reflex arc pathway?
Thus the correct sequence is a sensory receptor, sensory neuron, interneuron, motor neuron and last effector.
What must occur first in a reflex arc?
The reflex arc is a special type of neural circuit that begins with a sensory neuron at a receptor (e.g., a pain receptor in the fingertip) and ends with a motor neuron at an effector (e.g., a skeletal muscle).
Which is the correct order for transmission of a nerve impulse from a receptor to an effector?
The impulse is relayed from the sensory neurone-> synapse-> relay neuron in the grey matter of the spinal cord. Impulse will continue across synapse ->: motor neuron-> effector.
Which is the correct order of events in a reflex arc quizlet?
Place the following events of a reflex arc in the correct order: 1) motor neuron activation, 2) sensory neuron activation, 3) sensory receptor activation, 4) Information processing, 5) effector response.
What is the correct order for the movement of impulses?
Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse.
What is the correct order for the transmission of an impulse in a motor neuron?
Dendrites —->cell body—->axon—->nerve endings.
Which of the following parts of a reflex arc starts the reflex?
Explanation: Reflex arc starts with a stimulus. The stimulus must be sufficiently strong to initiate impulse in sensory neuron. Sensory neuron carries the impulse to intermediary neuron.
Which of the following are components of the reflex arc?
Terms in this set (5)
- Receptor. site of stimulus action, where you percieve the stimulus.
- Sensory Neuron. carries afferent infor into the CNS.
- Integration. syanpses within the CNS in the spinal cord.
- Motor Neuron. carries afferent info away from the CNS to effector organ.
- Effector. muscles or glands that respond to the signal.
