CSD 155 EXAM 1 VERIFIED STUDY GUIDE
Pinna - Answers - Funnels sound to the ear canal and helps localize sound
External auditory meatus - Answers - Known as the ear canal. Increases the intensity of
sound waves by contracting them in a smaller area. Earwax helps keep the ear canal
clean and it smells bad to keep the bugs out
Tympanic membrane - Answers - Known as the eardrum. Cone shaped structure of
tissue that concentrates sound at center. Sound waves hit it, causing it to vibrate.
Middle ear space - Answers - Lined with mucus membrane and filled with air.
Connected to the Eustachian tube
Eustachian tube - Answers - connects the middle ear with the nasopharynx and allows
passage of air. Passageway for air to move in and out of middle ear
Ossicles - Answers - malleus, incus, stapes. Connect the eardrum to the inner ear and
amplify the vibration of the eardrum. They are the smallest bones in the body.
Vestibule - Answers - Sense of balance and maintenance of the body positioning
Semicircular canals - Answers - Help maintain balance and filled with fluid
Cochlea - Answers - Snail shaped that has mechanical impulses from the metal ear are
converted to electrical impulses. High frequency sounds stimulate the base, low
frequency sound simulate the tip, vibration stimulates the hair cells
Acoustic nerve - Answers - Carries electrical impulses from the cochlea to the brain
Primary auditory area in the Temporal lobe
Air conduction - Answers - sound waves travel through the air to the outer ear and are
transmitted through the middle ear to the cochlea
Bone conduction - Answers - Vibration of the bone cause movement in the fluids of the
inner ear. The larger bones of the skull conduct sound because they vibrate in response
to airborne sound waves
respiratory, phonatory, articulatory, nervous , audiotory - Answers - What is the physical
system of communication
Respiratory - Answers - Energy source for speech
, Phonatory - Answers - vibratory source
Articulatory - Answers - shaping the oral cavity for production of speech sounds
Nervous - Answers - Control of speech processes; central and nervous
Teeth - Answers - Tear or bite
Tongue - Answers - Suck and swallow
Lips - Answers - Suck
Velum - Answers - Protect, smell, suck
Larynx - Answers - Protect and support
Anatomy - Answers - Study of structure of organism and the relation of their parts
Physiology - Answers - The science dealing with function of living organisms and their
parts
Histology - Answers - The study of cell structure of tissue
Clinical anatomy - Answers - Anatomy as related to pathological entity, and especially
as related to surgery. Study of treatments of disorders
Comparative anatomy - Answers - Anatomy that studies interspecies comparisons.
Looking at the common or compare something
Embryology - Answers - Known as developmental anatomy. Anatomy with reference to
period from conception to birth
Descriptive anatomy - Answers - Anatomy as related to the systems of body
System - Answers - A group of organs that function together for some purpose. Cells
make up tissues, tissue makes up organs, group of organs operate in this fashion
Coronal plane - Answers - divides body into front and back
Sagittal plane - Answers - Divide body into left and right
Transverse plane - Answers - Divide body into top and bottom
Superior - Answers - Above or top
Inferior - Answers - Below or bottom
