2 types of reflex arc | Autonomic reflex arc and Somatic reflex arc |
Type of reflex arc that affecting cardiac + smooth muscles and glands | Autonomic reflex arc |
Type of reflex arc that affecting skeletal muscles | Somatic reflex arc |
Detects a stimulus | Receptor |
Sends an electrical signal to the CNS | Sensory (afferent) neuron |
Sends an electrical signal from the CNS to the effector | Motor (efferent) neuron |
Simplest reflex arcs | Single synapse |
True/False: Shorter path = longer delay | False. Longer path = longer delay |
Sometimes called the stretch reflex or myotatic reflex because of the stretch action and the muscle response involved. | Deep tendon reflex |

Happens when a nerve is stimulated and the muscle relax and contracts. | Simple Muscle Twitch |
Start of contraction to the maximum strength of contraction | Contraction Period |
NA | NA |
When the muscle starts relaxing from the maximum point of contraction to end of relaxation | Relaxation Period |

This means that the inside of the neuron is 70 mV less than the outside | Resting Membrane Potential (RMP) |
Occurs when the membrane potential of a specific cell location rapidly rises and falls (Depolarization) | Action Potential |
It is the site for the transmission of action potential from nerve to the muscle. | Neuromuscular Junction |
Is the process by which different motor units are activated to produce a given level and type of muscle contraction | Motor Unit Recruitment |
Physiological unit of the Nervous System | Neuron (nerve cell) and its corresponding nerve fibers |
2 classification of nerve fibers based on the character of the results of impulses | Afferent (sensory) and Efferent (motor) nerve fibers |
Form of stimulation based on the procedure: Pinch the free end of the nerve immediately release after a tracing is recorded. | Mechanical stimulation |
Form of stimulation based on the procedure: Touch the free end of the nerve lightly with a warm glass rod and release after a tracing is recorded. | Thermal stimulation |
Form of stimulation based on the procedure: Place few crystals of NaCl on the free end of the nerve and release after a tracing is recorded. | Osmotic type stimulation |
Form of stimulation based on the procedure: Dip the free end of the nerve in a 50 mL beaker filled with 1% HCl solution. | Chemical stimulation |
