1
Q

In-order to feel temperature we rely on what receptor(specifically)

A

TrypV1

2
Q

Describe the Trypv1 mechanism (how the body senses pain/ temperature)

A

Temperature causes confirmational change in structure of Tryp1—>signal to brain

Poke breaks cells releasing molecules that bind to TrypV1 activates cell—>signal to brain

3
Q

what are the 3 types of nerve fibers

A

A-beta (fast)
A-delta(medium)
C(slow)

{Acronym: Alphabetical A-B, A-D, C} [Fast, Medium Slow}

4
Q

what factor causes one type of nerve fiber to vary in speed from another

A

Level of Myelination

Myelin=faster

5
Q

What is the gate control theory

A

non-painful input closes the”gates” to painful input

prevents pain sensation from reaching the central nervous system

6
Q

How do we smell?

A

100 of different olfactory epithelial each sensitive to one particular molecule. They
all send projections to one glomerulus respective to their specialization. Then they
synapse onto a mitral/tufted cell which signals to the brain

7
Q

labeled line theory of olfaction

A

describes a scenario where each receptor would

respond to specific stimuli and is directly linked to the brain

8
Q

vibrational theory of olfaction

A

Says that different vibrational frequencies of molecules give odor profile

9
Q

Steric theory or shape theory of olfaction

A

states that molecules shape fits receptors like lock and key

10
Q

inability to percieve odar

A

Anosmia (Acronym:

aNOSEmia = Smell)

11
Q

what are the 5 main tastes ?

A

bitter, salty, sweet, sour, and umami (ability to taste glutamate

12
Q

what is another word for the outer ear?

A

Pinna

13
Q

Theory of hearing which state that our preception of sound depends on where each component of frequency produces vibrations along the basal membrane

A

Place theory

14
Q

what is your somatosenory Homunculus?

A

It is a “topographical” sensory map of your body located in the “sensory strip” of your brain

15
Q

what region of the brain is the Humunculus located?

A

inside the sensory cortex. located in the cortex/perietal lobe

16
Q

what is the sens that is responsible for balance and posture?

A

Proprioception

17
Q

what is the name of the little receptors located in our muscles that contribute to our proprioception sence

A

Spindle

18
Q

what are the differences and similarities between Kinaesthesia and Proprioception

A

both tell us where are body is in space

Kinaesthesia- sense of movement

Proprioception- sense of balance and position
