This Exam contains:

-Guarantee passing score -41 Questions and Answers -format set of multiple-choice -Expert- Explanation

Question 1: What is sensation

Answer:

a feeling that occurs when the brain becomes aware of sensory impulses

Question 2: mechanoreceptors respond to

Answer:

mechanical forces

Question 3: what is proprioception and what kind of receptor does it use

Answer:

information send to spianl cord and CNS about body position and length, and tension of muschles. (3D space) -mechanoceptors Question 4: what sense is associated with body surface such as touch, pressure, temperature, and pain

Answer:

exteroceptive

Question 5: another name for visceral senses

Answer:

interoreceptors

Question 6: chemoreceptors respond to

Answer:

changes in chemical concentrations

Question 7: pain inhibiting substances

Answer:

-enkephalins -serotonin -endorphins

Question 8: stretch receptors

Answer:

muscle spindles, and golgi tendon organs

Question 9: chronic pain fibers

Answer:

-C fibers -thin, unmyelinated -conduct impulses more slowly associated with dull, aching pain -difficult to pinpoint Question 10: what sense is associated with changes in the viscera such as blood pressure stretching blood vessels and ingestion of a meal

Answer:

visceroceptive

Question 11: Describe and locate where general senses are

Answer:

Widely distributed throughout the body, in the skin, various organs, and joints

Question 12: 5 facts of visceral pain

Answer:

-pain receptors are the only receptors in viscera whose stimulation produces sensations -pain receptors respond differently to stimulation -pain receptors are not well localized -pain receptors may feel as if coming from some other part of the body

Question 13: Pacinian

Answer:

-Common in deeper subcutaneous tissues, tendons and ligaments -detect heavy pressure and vibrations

Question 14: regulation of pain impulses

Answer:

-thalamus -cerebral cortex -pain inhibiting substances

Question 15: warm recpetor ranges

Answer:

sensitive to temperatures above 25 but below 45

Question 16: What is Sensory adaptation

Answer:

-ability to ignore unimportant stimuli -sensory impulses become less frequent and may cease -stronger stimulus is required to trigger impulses.

Question 17: temperature senses are only receptive between what temperatures

Answer:

10-45 degrees

Question 18: Cerebral cortex -regarding pain

Answer:

-judges intensity of pain -locates source of pain -produces emotional and motor responses to pain

Question 19: What do sensory receptors do

Answer:

Stimulate neurons to send impulses along sensory fibers to the brain.

Question 20: 3 types of touch and pressure senses

Answer:

free nerve endings, meissner's, & pacinian

Question 21: name the two sense categories

Answer:

General Senses and Special Senses

Question 22: Receptor Types

Answer:

Chemoreceptors, nocioceptors, thermoreceptors, mechanoreceptors, photoreceptors

Question 23: Main kinds of proprioceptors

Answer:

pacinian, muscle spindles, and golgi tendon organs

Question 24: Meissner's

Answer:

-abundant in hairless portions of skin and lips -detect fine touch; distinguish between two points on the skin

Question 25: cold recepter ranges

Answer:

sensitive to temperatures between 10-25 degrees

Question 26: free nerve endings

Answer:

-common in epithelial tissues -simplest receptors -sense of itching
