Term
|
Definition
| when a stimulus on one side of the body creates a response on both sides of the body (pupil response) |

Definition
mono: does not involve integration
poly: involves integration |
|
|
Term
|
Definition

Term
|
Definition
| sensory receptor that recieves stimulus from within the body, i.e. the gut and internal organs |
|
|
Term
|
Definition
| external sensory receptors located on skin, eyes, oral cavity, ears, etc. |
|
|
Term
|
Definition
| sensory nerve endings that provide information regarding body positioning |
|
|
Term
|
Definition
| the change in response to stimulus recieved by sensory receptors over time (decreased sensitivity) |
|
|
Term
|
Definition
| the time it takes for a muscle to react to a stimulus |
|
|
Term
|
Definition
| made up of a motor neuron and the muscle fibers it innervates |

|
Term
|
Definition
| the graduated, increasingly vigorous contractions that result from a series of identical stimuli (staircase effect) |
|
|
Term
|
Definition

|
|
Term
| Wave or Temporal Summation |
|
Definition
| Potential summation occuring from repeated stimulation from a single presynaptic neuron |

Term
|
Definition
| Summation of stimuli from multiple presynaptic neurons on one postsynaptic neuron |

|
Definition
| Reduction in the nerves ability to produce sustained stimuli, O2 depletion, ATP depletion, etc. |
|
|
Term
| isotonic/metric contractions |
|

Term
| automaticity/autorhythmicity |
|
Definition
| ability to perform repetitive tasks "automatically" without conscious effort, or in the case of the heart, the ability to beat rhythmically without external stimulation |
|
|
Term
|
Definition
| taking place or functioning in ordered rhythmic fashion because of the inherent properties of cardiac muscle rather than specific neural stimuli |
