Question
Answer
these receptors react to various chemicals, including odors and tastes, as well as the concentration of various chemicals in the body   Chemoreceptors  
🗑
these receptors respond to factors such as pressure, stretch, or vibration, that change the position of the receptor.   Mechanoreceptors  
🗑
these receptors are activated by change in the temperature   Thermoreceptors  
🗑
these are pain receptors that respond to tissue damage from trauma as well as form heat, chemicals, pressure, or lack of oxygen   Nociceptors  
🗑
found in only the eyes, these receptors respond to light   Photoreceptors  
🗑
abundant in the skin and mucous membranes, these fibers produce a sharp, localized, stabbing-type pain at the time of injury   Fast pain fibers  
🗑
these fibers are congregated on deep body organs and structures and produce a dull, aching pain.   Slow pain fibers  
🗑
the since of taste is called   Gustation  
🗑
taste buds are located in the protrusions on the tongue called   Papillae  
🗑
these are large papillae found at the rear of the tongue   Vallate Papillae  
🗑
these form ridges at the sides of the tongue   Foliate Papillae  
🗑
these are thread-like papillae that contain no taste buds   Filiform Papillae  
🗑
these are especially concentrated at the tip of the tongue   Funfiform Papillae  
🗑
a pair of structures that are residing just underneath the brain's frontal lobe   Olfactory Bulbs  
🗑
the since of smell is called   Olfaction  
🗑
the visible part of the ear is called   Auricle (pinna)  
🗑
this part of the ear leads through the temporal bone to the eardrum   Auditory Canal  
🗑
the opening of the auditory canal to the outside of the body is called   External Acoustic Meatus  
🗑
the three small bones in the ear are called   Auditory Ossicles  
🗑
the bone in the ear that is shaped like a hammer is called   Malleus  
🗑
the bone in the ear that is shaped like an anvil is called   Incus  
🗑
the bone in the ear that is shaped like a stirrup is called   Stapes  
🗑
the eardrum is called the   Tympanic membrane  
🗑
this is a passageway from the middle ear to the nasopharynx   Auditory/ Eustachian tube  
🗑
these structures are curial for the maintenance of equilibrium and balance   Semicircular canals  
🗑
this structure, which marks the entrance to the labyrinths, contains organs necessary for the sense of balance   Vestibule  
🗑
this snail like structure contains the structures for hearing   Cochlea  
🗑
the triangular duct that is filled with endolymph is called   Cochlea duct  
🗑
the fluid that cushions the space between the two labyrinths is called   Perilymph  
🗑
a fluid that occupies the inside of the membranous labyrinth is called   Endolymph  
🗑
this lines the inside of the bony labyrinth   Membranous labyrinth  
🗑
thousand of hair like cells project from the epithelial layer and are topped with a gelatin like membrane called   Tectorial membrane  
🗑
at the end of each canal is a bulb like area called an   Ampulla  
🗑
the hair part of the face, that helps shield eye from glare.. (hint girls color this in with make up ... sometimes alil to much)   Eyebrows  
🗑
these are form primarily the orbicularis oculi muscle covered in skin, it protects the eye from foreign bodies and block light when closed   Eyelids  
🗑
the opening between the lids is called   Palpebral fissure  
🗑
the hairs on the eyelids that help keep debris out of eye are called   Eyelashes  
🗑
the transparent membrane that lines the inner surface of the eyelid and covers the anterior surface of the eyeball is called   Conjunctiva  
🗑
these glands lie along the thickened area at the edge of the eye   Tarsal plate  
🗑
this small gland secretes tears that flow onto the surface of the conjunctiva   Lacrimal gland  
🗑
this passageway carries tears into the nasal cavity   Nasolacrimal duct  
🗑
this is a tiny pore through which tears drain into the lacrimal canal and the nasolacrimal duct   Lacrimal Punctum  
🗑
the study of the eye and the treatment of its diseases is called   Ophthalmology  
🗑
form from dense connective tissue this is the outermost layer of the eye   Sclera  
🗑
the thin layer of the light sensitive cells in the eye is called   Retina  
🗑
exiting from the posterior portion of the eyeball is the ________, which also transmits signals to the brain   Optic nerve  
🗑
this is a ring of colored muscle in the eye   The Iris  
🗑
the thickened extension of the choroid that forms a collar around the lens is called the   Ciliary body  
🗑
the highly vascular tissue that supplies oxygen and nutrient to the retina and sclera is called the   Choroid  
🗑
the center point of the retina is a patch of cells called the   Macula Lutea  
🗑
inside the macula lutea is a depression called the   Fovea centralis  
🗑
medial to the macula lutea is the   Optic disc  
🗑
the space between the lens and the cornea is the   Anterior cavity  
🗑
the cleat watery fluid that fills the anterior cavity is called   Aqueous humor  
🗑
the transparent disc of tissue just behind the pupil, between the anterior and posterior cavities is called   the lens  
🗑
the larger cavity that lies posterior to the lens is called the   Posterior cavity  
🗑
the posterior cavity is filled with a jelly like substance called   Vitreous humor  
🗑
bending light rays is called   Refraction  
🗑
this lines up the visual axis of each eye toward the object so that the light rays fall on the corresponding spots on each retina   Convergence  
🗑
the sharpness of visual perception is called   Visual acuity  
🗑
this muscle encircles the pupil   Pupillary constrictor  
🗑
when you eyes let in light to see your pupil become more open this is called   Pupillary dilator
