| 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 |
| the curvature of the lens changes to allow the eye to focus on a near object is called | Accommodation |
| these active in dim light | Rods |
| these are activated in bright light | Cones |
