Chapter 28 Face And Neck Injuries Flashcards
A fracture of the orbit, or the bones that support the floor of the orbit
Blowout fracture
Separation of the retina from attachments at the back of the eye
Retinal detachment
Naturally occurring uneven pupil size
Anisocoria
The ear canal leads to the tympanic membrane
External auditory canal
The delicate membrane that lines, the eyelids and covers the exposed surface of the eye
Conjunctiva
Layers of the bone within the nasal cavity
Turbinates
The transparent tissue layer in front of the pupil and iris of the eye
Cornea
The eyeball
Globe
The muscles on either side of the neck that allow movement of the head
Sternocleidomastoid muscles
A tube that connects the middle ear to the oropharynx
Eustachian tube
A characteristic crackling sensation fell on palpation of the skin caused by the presence of air in soft tissues
Subcutaneous emphysema
The eardrum, a thin, semi transparent membrane in the middle ear that transmit sound vibrations to the internal error, by means of auditory ossicles
Tympanic membrane
The presence of air the veins which can lead to cardiac arrest if it enters the heart
Air embolism
The small rounded fleshy bulge that lies immediately anterior to the ear canal
Tragus
The glands that produce fluids to keep that eye moist. Also called tear glands.
Lacrimal glands
The transparent part of the eye, through which images are focused on the retina
Lens
The external visible part of the ear
Pinna
The tough fibrous white portion of the eye that protects the more delicate inner structures
Sclera
The prominent bony mass at the base of the skull about 1 inch, 2.5 cm posterior to the external opening of the ear
Mastoid process
The circular opening in the middle of the iris that admits light into the back of the eye
Pupil
A cranial nerve that transmits visual information to the brain
Optic nerve
Inflammation of the conjunctiva
Conjunctivitis
The joint formed where the mandible in cranium meet just in front of the ear
Temporomandibular joint
A light sensitive area of the eye wear. Images are projected a layer of cells at the back of the eye that changes the light image into electric impulses, which are carried by the optic nerve to the brain.
Retina
The muscle, and surrounding tissue behind the cornea that dilate and constrict the pupil regulating the amount of light that enters the eye pigment in this tissue give that eye its color
Iris
