Bodily senses

Question 1

There are at least six distinct bodily or somatic senses:

Answer 1

touch
temperature
pain
position/motion
balance, and
interoception (perception of bodily sensations).

Question 2

The top layers of skin have receptor cells that are sensitive to different tactile qualities—some to shape, some to grooves, some to vibrations and movements.

Answer 2

MECHANORECEPTORS

Question 3

The top layers of skin have receptor cells that are sensitive to different tactile qualities—some to shape, some to grooves, some to vibrations and movements.
for the eyes, this is the

Answer 3

Photoreceptors

Question 4

The top layers of skin have receptor cells that are sensitive to different tactile qualities—some to shape, some to grooves, some to vibrations and movements.
for the ears this is the

Answer 4

hair cells

Question 5

Tactile sensations from our skin travel via —————— and up to the brain

Answer 5

sensory neurons to the spinal cord

Question 6

The first major structure involved in processing bodily sensations is the

Answer 6

thalamus

Question 7

The first major structure involved in processing bodily sensations is the thalamus, which relays the impulses to the ———– in the parietal lobe.

Answer 7

somatosensory cortex

Question 8

A complex emotional and sensory experience associated with actual or potential tissue damage.

Answer 8

Pain

Question 9

When people who have lost a limb feel pain in the missing arm or leg. Such cases dramatically show how pain is not just a direct result of tissue damage, but an experience in the brain as well.

Answer 9

Phantom Limb Pain

Question 10

Pain from skin and/or tissue damage or injury is called —————–

Answer 10

nociceptive pain.

Question 11

send signals to the spinal cord and then to the brain, signaling that damage has occurred.

Answer 11

Nociceptors

Question 12

A somewhat surprising finding is that some of the same brain regions and neurochemicals activated when we experience physical pain are also activated during emotional pain—especially when we are rejected by others or see others receive shocks

Even more fascinating, the same brain regions ———————— are activated whether we experience pain directly or observe someone else get hurt

Answer 12

(Anterior cingulate cortex and insula)

Question 13

our bodies natural painkillers
When we are hurt, our bodies respond by releasing these substances

Answer 13

endorphins

Question 14

are very important survival-related senses, for they govern our choices about what we take into our bodies.

Answer 14

Smell and taste

Question 15

true or false

Smell and taste receptors are replaced every few weeks.

Answer 15

true

Question 16

The sensory receptors for smell that reside high up inside the nose.
contains cilia, hairlike projections

Answer 16

Olfactory sensory neurons

Question 17

convert the chemical information in odor molecules into neural impulses

Answer 17

Cillia

Question 18

contains cilia,

hairlike projections

Answer 18

Olfactory Sensory Neurons

Question 19

sends information either directly to the smell-processing areas in the cortex or indirectly to the cortex by way of the thalamus

Answer 19

Olfactory Bulb

Question 20

sends smell information to the thalamus, hypothalamus and frontal cortex.

Answer 20

Amygdala

Question 21

plays a key role in emotional responses and connects to memory areas such as the hippocampus. These connections may explain why smells can instantly evoke an emotional memory.

Answer 21

Amygdala

Question 22

5 sensory cortices

Answer 22

Olfactory - smell
Gustatory - taste
Visual - vision
Auditory - hearing
Somatosensory - touch

Question 23

textured structures
contain about 10,000 taste buds

Answer 23

Papillae

Question 24

Sensory receptors for taste that reside in the taste buds

Answer 24

taste receptor cells

Question 25

ocated in the insula region of the frontal lobe right where the temporal and parietal lobes intersect

Answer 25

Gustatory cortex
