Receptors
What are thermoreceptors?
This structure is labeled 'a' in the diagram on page 311.
What is pinna?
This structure of the inner ear contains the organ of hearing.
What is the cochlea?
This is part of the fibrous tunic, is the 'white' of the eyeball, and is labeled 'b' in the diagram on page 313.
What is sclera?
This is the colored, circular muscle of the eye, responsible for opening and closing the pupil depending on light conditions.
What is the iris?
These are sensory receptors that respond to excess stimulation or pain.
What are nociceptors?
This structure is labeled 'c' in the diagram on page 311.
What is tympanic membrane?
This is the first structure to vibrate when sound waves hit your ear.
What is the tympanic membrane? (or eardrum)
This is the innermost, photosensitive layer of the eye, labeled 'e' in the diagram on page 313.
What is the retina?
This fluid helps maintain pressure within the anterior and posterior chambers and acts as a circulatory system for the front of the eye, providing nutrients and removing waste products.
What is aqueous humor?
These receptors are found in muscles and tendons and provide continuous feedback to the CNS regarding body position, movement, and tension.
What are proprioceptors?
This is the collective term for the three smallest bones in the human body, labeled 'd' in the diagram on page 311.
What are auditory ossicles?
This is the last structure to vibrate when sound waves hit your ear.
What are hair cells? (or tectorial membrane within the cochlea
This is the middle, vascular tunic of the eye, helping absorb light rays to improve sharpness of vision. (labeled 'f' in the diagram on page 313.)
What is the choroid?
These two structures in the eye are the most important for bending light so that it focuses properly.
What are the cornea and lens?
These cutaneous receptors respond to heat, cold, itch, and pain.
What are free nerve endings?
This is the snail like structure found in the inner ear, labeled 'f' on page 311.
What is the cochlea?
This structure contains the cupula and is involved in dynamic equilibrium?
What are the semicircular canals?
This is the gel-like substance that helps maintain the overall shape of the eye, labeled 'd' in the diagram on page 313.
What is vitreous humor?
**DAILY DOUBLE**
These are the two main types of photosensitive cells found in the retina.
-This is the name of area on the retina where one of these cell types is concentrated-
What are rods and cones?
-Cones are concentrated in the fovea centralis-
These cutaneous receptors respond to light touch or pressure, and were specifically tested during the two-point discrimination lab.
What are Meissner's corpuscles?
This is the name for the three tubes oriented on different axes and found in the inner ear. (Labeled 'e' in the diagram on page 311.)
What are the semicircular canals?
This structure should be investigated if static equilibrium was compromised.
What is the utricular macula?
This structure is a clear, anterior extension of the sclera. It is the structure where light first enters the eye and is labeled 'j' in the diagram on page 313.
What is the cornea?
These three structures are involved in the process of accommodation.
What are the ciliary body, suspensory ligaments, and lens?
