Question 0

Neurotransmitters mediating analgesia

Answer 0

Serotonin, enkephalins

Question 1

Chemical substance most responsible for causing pain

Answer 1

Bradykinin

Question 2

Endogenous opioids

Answer 2

Morphine and morphine-like substances

Question 3

Explain gate control theory of pain

Answer 3

Due to lateral inhibitiin

Question 4

Explain referred pain

Answer 4

Related to convergence theory

Question 5

Factor that most dramatically increases metabolic rate and body heat

Answer 5

Strenuous exercise

Question 6

Produces body heat in response to cold stress

Answer 6

Shiverigg

Question 7

Primary motor center for shivering

Answer 7

Posterior hypothalamus

Question 8

Hormones that influence heat production

Answer 8

Thyroxine increaes metabolic rate
Growth hirmone increase cellular metabolism and skeletal muscle mass
Testosterone increases metabolic rate
Epi and norepi increases sympathetic stimulation of cells

Question 9

Sympathetic activity that increaes heat production

Answer 9

Vasoconstriction
Piloerection
Non shivering thermogenesis

Question 10

Digestion of (protein/fat/carb) produces the most heat production

Answer 10

Protein

Question 11

Most effective way of losing heat

Answer 11

Radiation

Question 12

Mechanism of wind chill

Answer 12

Wind disrupts the epiclimate and increaes the rate by which the body loses heat by convection

Question 13

Function of anterior hypothalamus in temp regulation

Answer 13

Cools down the body

Damage to this area causes hyperthermia

Question 14

Function of posteriir hypothalamus in temp regulation

Answer 14

Heats up the body

Damage leads to hypothermia

Question 15

Describe attenuatiin reflex

Answer 15

Decreased sensitivity to own voice and background noise

Reduction in conduction if low frequency siunds

Question 16

Descrive tympanix reflex

Answer 16

Increases the stiffness of the eardrum by the contraction of the stapedius and tensor tympani to reduce intensity of low frequency sound transmission

Protects from damaging loud vibrations

Question 17

Difference of medial and lateral olfactory tract

Answer 17

Medial olfactory tract mediates primitive responses to olfactory stimuli
Lateral tract relates with memories from the hippocampus
