Flashcards in Sixtho Longs Deck (18):
0

Chemical substance most responsible for causing pain

Bradykinin

1

Neurotransmitters mediating analgesia

Serotonin, enkephalins

2

Endogenous opioids

Morphine and morphine-like substances

3

Explain gate control theory of pain

Due to lateral inhibitiin

4

Explain referred pain

Related to convergence theory

5

Factor that most dramatically increases metabolic rate and body heat

Strenuous exercise

6

Produces body heat in response to cold stress

Shiverigg

7

Primary motor center for shivering

Posterior hypothalamus

8

Hormones that influence heat production

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

9

Sympathetic activity that increaes heat production

Vasoconstriction
Piloerection
Non shivering thermogenesis

10

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

Protein

11

Most effective way of losing heat

Radiation

12

Mechanism of wind chill

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

13

Function of anterior hypothalamus in temp regulation

Cools down the body
Damage to this area causes hyperthermia

14

Function of posteriir hypothalamus in temp regulation

Heats up the body
Damage leads to hypothermia

15

Describe attenuatiin reflex

Decreased sensitivity to own voice and background noise
Reduction in conduction if low frequency siunds

16

Descrive tympanix reflex

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

17

Difference of medial and lateral olfactory tract

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