| What is the sequence of a simple spinal reflex arc? |
|
Definition
| 1.) Receptor 2.) Sensory neuron 3.) Integration center 4.) Motor neuron 5.) Effector |
|
|
Term
|
Definition
| these are also called the viceroceptors, respond to stimuli withing the body (intero=inside). They monitor a variety of stimuli, including chemical changes, tissue stretch, and temperature. Sometimes their activity causes us to feel pain, discomfort, hunger, or thrist. We are usually unaware of their workings. |
|
|
Term
|
Definition
| these are sensitive to stimuli arising our the body. So most exteroceptors are near or at the body surface. This includes touch, pressure, pain, and temperature receptors in the skin and most receptors of the special senses. |
|
|
Term
|
Definition
| These are like interoceptors, they respond to internal stimuli; however, their location is much more restricted. These occur in the skeletal muscles, tendon, joints, and ligaments and in connective tissue coverings of bones and muscles. This receptors advise our brain of our body movements. |

|
Term
| What are the 5 essential components for a reflex arc? |
|
Definition
1.) Receptors- Site of the stimulus aciton
2.) Sensory neuron- Transmits afferent impulses to the CNS.
3.) Integration center- In simple reflex arcs, the intergration center may be a single synapse between a sensory neuron and motor neuron.
4.) Motor neuron-Conducts efferent impulses from the integration center to an effector organ.
5.) Effector- Muscle fiber or gland cell that respondsto the efferent impulses(by contracting or secreting.) |

|
Term
|
Definition
| Respond to potentially damaging stimuli that result in pain. For example, searing heat, extreme cold, exessive pressure, and inflammatory chemicals are all interpreted as painful. These signals stimulate subtypes of thermoreceptors, mechanreceptors, and chemoreceptors. |
