Q

Receptive Fields

A

What each repect is able to sense.

Specialization

Cones -see red,blue green anad light, not great at senseing motion

Robs- are really good at seeing mothing but they arent good at seeing colos

Q

Retna

A

the light-sensitive layer of tissue at the back of the eyeball. Images that come through the eye’s lens are focused in retina.

Q

Cones:

A

Provide sharp images in bright light and color vision (3 colors)
Fovea contains densely packed cones, but no rods

16
Q

Rods:

A

More sensitive to light than cones, function in dim light
Provide black and white vision
Provide less precise images (general outlines) than cones,
There are many more rods than cones in the retina

17
Q

Hearing

A

As the fluid moves, 25,000 Hair cells, are set into motion. These Hair cells transform the vibrations into electrical impulses that then travel along the auditory nerve to the brain. The brain then interprets these signals, and this is how we hear.

18
Q

Cochlea

A

a fluid-filled, spiral-shaped cavity found in the inner ear that plays a vital role in the sense of hearing and participates in the process of auditory transduction.

19
Q

Somatic Pain

A

: skin and muscles, respond to damage to tissue
tearing, burning, electrical, chemical

20
Q

Visceral Pain

A

internal organs, respond to massive damage
Only receptors that organs have
Stretching, tissue death, emergency chemicals, loss of blood flow

21
Q

Referred pain:

A

when visceral response is confused with somatic

22
Q

Taste buds

A

Taste buds are mostly found on the tongue
Sweet, salty, sour, bitter, umami
All are distributed on the tongue, some areas densely

23
Q

taste hairs

A

Grabs the material and shoves it into the taste bud.

24
Q

Olfactory cells

A

Smell is Dependent on olfactory cells, which carry receptor proteins
Estimated that there are 400 receptor proteins

25
Q

Olfactory Bulb

A

The receptor area of smells

26
Q

Name the five main senses

A

touch, sight, hearing, smell and taste

27
Q

Compare sensation, perception, and projection

A

WIND EX

WInd blows the SENSATION goes to a signal to ur brain and gets intpersted ( PERCETPTION) and then the Porjection is where you undertand that the wind blew on your arm

28
Q

Explain situations using receptive fields

A

This is the reason you see Motion before you see color beacuse rods spesisle in seeing motion as opposed to colors like cones.

29
Q

Describe how we see

A

When light hits the retina, special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.

30
Q

Compare rods and cones

A

Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity.

31
Q

Describe how we hear

A

As the fluid moves, 25,000 Hair cells, are set into motion. These Hair cells transform the vibrations into electrical impulses that then travel along the auditory nerve to the brain. The brain then interprets these signals, and this is how we hear.

32
Q

Compare somatic and visceral pain receptors

A

Somatic Pain is pain in your muscles, skin, or bone. This pain is focused on a specific area and could be the type of pain you feel with movement, when experiencing a headache, or when you cut your skin. Visceral Pain is pain experienced in your internal organs and it can be harder to centralize or identify

33
Q

Describe the process of taste

A

Taste buds have very sensitive microscopic hairs . Those tiny hairs send messages to the brain about how something tastes, so you know if it’s sweet, sour, bitter, or salty.

34
Q

Describe the process of smell

A

When you smell an odor, you’re actually breathing in tiny molecules. These molecules stimulate specialized nerve cells, called olfactory sensory neurons, high inside the nose. Sends signals to your brain and your brain begins to interpert the smell.

35
Q

Aside from the five main senses, what other senses are there?

A

Thermoception – we know whether our environment is too cold or too hot. Being able to sense the temperature around us helps keep us alive and well.

.

Proprioception includes the sense of movement and position of our limbs and muscles.

36
Q

Why did pirates wear eyepatches?

A

an eye patch was used to condition the eye so the pirate could go down to the storage area beneath the deck and have an eye that can see in the dark!

37
Q

What are the only stimuli that the organs can detect?

A

Stretching, thats why you feel gas, it streches our organs

38
Q

How does referred pain happen?

A

when you have an injury in one area of your body but feel pain somewhere else. This happens because all the nerves in your body are part of a huge, connected network

39
Q

What are the five tastes?

A

sweet, sour, bitter, salty and umami.
