These are found in the skin and detect either heat or cold
What are thermoreceptors

This part of the ear includes the pinna, the fleshy structure we commonly refer to as our ear, and the auditory canal. Together these collect and funnel sound into the middle ear
What is the outer ear
100
Light enters the eye through a small opening at the center of the eye, what is this small opening called?
What is the pupil
100
this membrane lines the inner surface of the eyelids and folds back over the white of the eye
What is the conjunctiva
100
sensory neurons that line the upper naval cavity, sending impulses along axons directly to the olfactory bulb
What is olfactory receptor
200
These are stimulated by mechanical energy, such as touch, pressure, stretching, motion, and sound, to bend or stretch, resulting in tension on the plasma membrane, causing it to become permeable to sodium or potassium
What are mechanoreceptors
200
This tissue separates the outer and middle ear
What is the eardrum
200
The sclera surrounds a pigmented layer, which also forms the iris, what is this called
What is choroid
200
the three most common vision problems
What is farsightedness, nearsightedness and astigmatism
200
what are the five taste perceptions?
What is sweet, sour, salty,bitter and umami
300
The skin has the highest density of these, which may respond to excess heat or pressure or to chemicals released from damage or inflamed tissues.
What is pain receptors
300
These are the three smallest bones in the human body, when sound pressure strikes the eardrum, it passes vibration to these which then amplify the vibrations
What are the malleus (hammer), incus (anvil), and stapes (stirrup)
300
The eye is divided into two fluid filled chambers what are they?
What is the vitreous humor and the aqueous humor
300
a photoreceptor stimulated by bright light and can distinguish color
What is cones
300
what is in your taste buds that detect molecules in solution
What is chemoreceptors
400
These include the sensory receptors in our nose and tastebuds, which are attuned to chemicals in the external environment, as well as some that detect chemicals in the bodys internal environment
What is a chemoreceptor
400
The middle ear opens into this passage which connects with the pharynx, allowing air pressure to remain at equilibrium with the outside of the ear
What is the Eustachian tube?
400
The large chamber behind the lens is filled with this jellylike substance
What is the vitreous humor
400
a photoreceptor that is extremely sensitive to light, enables us to see in dim light, and contains a visual pigment called rhodopsin
What is rods
400
this flavor enhancing chemical is mostly found th cheese, meat and other protein rich foods
What is monosodium glutamate
500
These detect energy as electricity, magnetism, or various wavelengths of light, include photoreceptors, which detect electromagnetic energy in visible or ultraviolet part of electromagnetic spectrum
What is an electromagnetic receptor
500
This is our actually hearing organ, found in the middle canal of the cochlea, which consists of an array of hair cells embedded in a basilar membrane. These hairs are the sensory receptors of the ear.
What is the organ of Corti?
500
the much smaller chamber in front of the lens contains this
What is the aqueous humor
500
this consists of up to several thousand light-detectors
What is ommatidia
500
this is an odorous substance that diffuses and disolves into the mucus, it can be bound to specific receptors proteins
