lobes Flashcards
you notice the air smells tasty
Inferomedial temporal lobe
you taste the salty spray in air
Inferior parietal lobe
You see large waves and the movement of your friend falling off his surfboard
Medial occipital lobe
You hear the roar of the waves and your friend’s laugh
Temporal lobe
You are aware that you are sitting up on your towel
Parietal lobe
Sensory information from skin, muscles, bones, and joints
Comes from the receptors of the eyes, ears, nose, tongue, and skin
Five senses
SOMATIC SENSES
Sensory information from viscera (internal organs such as heart, lungs, stomach, and bladder
Comes from internal organs
VISCERAL SENSES
temperature
Thermoreceptors
pain
Nociceptors
Vibration
Discriminatory touch and pressure
Mechanoreceptors
Sense changes in the chemical composition of the blood
Chemoreceptors
Converts light into electrical signals
Photoreceptors
Reminiscent of mint or peppermint
Often described as cool and refreshing
PEPPERMINTY
Associated with flowers
Wide range of floral scents from various types of flowers
FLORAL
Includes odors associated with musk, a substance secreted by certain animals and often used in perfumes
MUSKY
Strongly aromatic, almost medicinal scent
Includes odors reminiscent of camphor, which is a compound found often in medicinal and cleaning products
Eucalyptus, frankincense, hyssop, marjoram, rosemary, sage, camphor, mothballs
CAMPHORACEOUS
Odors that are light, and airy
Associated with substances like ethers or light hydrocarbons
ETHEREAL
Sharp, acrid, and often irritates the senses
Ammonia and certain spices
PUNGENT
Decay and decomposition
Similar to the smell of rotting flesh
PUTRID
Formed by groupings of taste receptor cells with hair-like extensions that protrude into the central pore of the (?)
Each taste bud has 50 to 100 taste receptor epithelial cells which register the different molecules in your food
Taste buds
Each taste bud has ? to ? taste receptor epithelial cells which register the different molecules in your food
50 to 100
Little bumps on top of your tongue that help grip food while your teeth are chewing
Contains our taste buds
PAPILLAE
Outermost layer
Sclera
Cornea
FIBROUS TUNIC
Middle layer
Choroid
Ciliary body
Iris
VASCULAR TUNIC (UVEA)
RETINA
RODS
CONES
NERVOUS TUNIC
Most numerous
Entire surface of the tongue
Pointed
Threadlike structures
Has no taste buds
FILIFORM
Type of photoreceptor cell in the retina
Sensitive to light levels and help give us good vision in low light
RODS
Type of photoreceptor cell in the retina
They give us our color vision
CONES
Most sensitive
Located at the lateral margins of the tongue
Foliate
Located in the center of the macula lutea
Responsible for high-acuity vision
Densely saturated with cone photoreceptors
FOVEA CENTRALIS
Results from decreasing lens elasticity that accompanies aging
PRESBYOPIA
Where ganglion cell axons exit the eye to form the optic nerve
No light sensitive rods or cones to respond to a light stimulus at this point
Causes a break in the visual field called the blind spot
OPTIC DISC
Nearsightedness
Near objects appear clear, but objects farther away look blurry
MYOPIA
