General Senses/ Special Senses
These sensory receptors sense changes in temperature.
What are thermoreceptors?
The area of the retina where the optic nerve exits the eye.
What is the blind spot or optic disc?
The sensory receptor type for the sense of hearing.
What are mechanoreceptors?
The primary taste sensations.
What are sweet, sour, salty, and bitter, umami
The white part of the eye.
What is the sclera?
The five special senses.
What are Vision, Hearing, Equilibrium, Smell, Taste?
Pulls on the lens to focus your vision
ciliary body (attached by suspensory ligaments)
The funnel-shaped portion of the external ear.
What is the auricle or pinna?
The type of receptor used for smell and taste.
What are chemoreceptors?
The type of sensory receptor that senses light and color.
What are photoreceptors?
The sense organs.
What are the eyes, ears, nose, tastebuds, and skin.
Photoreceptors that detect color and light in brightness.
What are cones?
Sequence of ossicles from eardrum to inner ear.
What is Malleus, Incus, Stapes?
The sensitive parts of taste receptor cells.
The portion of the eye through which light is bent the most.
What is the lens?
Sensations that are sensed by the general sense organs.
What are touch, pressure, pain, temperature, and chemical stimuli?
The dark, vascular layer that supplies nutrients to the retina and reduces light reflection in the eye.
What is the Choroid Coat?
This ossicle that taps on the oval window.
What is stapes?
Fluid that is necessary for dissolving food molecules, enabling them to be detected.
What is saliva?
The clear layer on the outside of your eye that helps to bend light.
What is the cornea?
What is referred pain?
The area of the retina that has the highest concentration of cones.
What is the fovea centralis?
This contains two membranous sacs that provide sensations of gravity and movement of head when stationary
vestibule
Taste buds are hidden from the mechanical stress of chewing because they lie along the sides of these epithelial projections...
papillae
What is the primary function of the lacrimal apparatus?
produce tears for the eye
This tactile receptor is abundant in hairless areas of skin and senses light touch, pressure, and low frequency vibrations.
Tactile (Meissner) Corpuscles
The phenomenon in which the ciliary muscles and suspensory ligaments enable the lens to adjust shape to facilitate focusing.
What is accomodation?
The bony labyrinth surrounds and protects these canals which are a collection of tubes and chambers that follow the contours of the surrounding bony labyrinth and filled with endolymph
Membranous labyrinth
The three nerves on which taste sensory impulses travel.
What are the facial, glossopharyngeal, and vagus nerves?
The structure that enables your ears to maintain equal air pressure on either side of the tympanic membrane.
What is the auditory tube (eustachian tube)?
These large receptors respond to heavy pressure and high-frequency vibrations and are found in deeper dermal/subcutaneous tissue, joint capsules, and the walls of the urethra and urinary bladder
Lamellated (Pacinian) Corpuscles
The photoreceptors that help you to see in dim conditions.
What are rods?
The organs of dynamic equilibrium.
What are the semicircular canals?
What is the path of a smell as it travels through the nose to the brain (hint: turns chemical into electrical)
substance being smelled, picked up by olfactory receptor cells, into olfactory nerve fibers, to the olfactory bulb, through the olfactory tract to the brain
The structure within the cochlea where the hair cells are bent against to pick up sound vibrations.
What is the tectorial membrane?
