Spinal Nerves have 2 divisions - Ventral and Dorsal.
What type of sensory neurons are containted in each division? |
|
Definition
Ventral - MOTOR
Dorsal - SENSORY |
|

The kind of stimulation used to evoke the the reflex.
"Knee Jerk Reaction" |

There are 7 Steps in the Stretch Reflex Arc Pathway.
Name it: |
|
Definition
This is a conduction Route.
1. Stimulus
2. Sensory Receptor
3. Sensory Neuron (Afferent)
4. Integration center/Interneurons
5. Motor Neuron (Efferent)
6. Effector
7. Response |

Term
|
Definition
| Tapping a tendon creates a sudden tug or SRETCH of a muscle belly. |
|
|
Term
|
Definition
| Muscle Spindle - a proprioceptor. a sensory receptor wrapped around muscle fibers in the muscle belly. |
|
|
Term
| 3. Sensory Neuron - AFFERENT |
|
Definition
| Afferent conducts sensory information TOWARD the CNS. (The spinal cord is the simplest of the CNS.) |
|
|
Term
| 4. Integration Center / Interneurons |
|
Definition
The sensory neuron synapses directly with motor neurons.
They are Monosynaptic - 1 reflex = 1 synapse |
|
|
Term
| 5. Motor Neuron - EFFERENT |
|
Definition
| Conducts impulse AWAY from the CNS to an effector. |
|

Definition
Occurs simultaneously - the motor pathway excites the agonist and inhibits the antagonist.
When a STRETCHED muscle contracts during the stretch reflex, the antagonist muscles relax.
This prevents contraction conflict between opposing muscles. This is vital in producing fluid and coordinated muscle movement. |

|
Definition
| Responses of smooth muscle, cardial muscle & glands |
