are protective structures. 3. Conjunctiva is from the eye, 4. Lacrimal apparatus produces and drains includes the lacrimal gland, which produces tears and mucus, lacrimal puncta, lacrimal canaliculi, lacrimal sac, and the nasolacrimal duct. 5. Extrinsic Eye Muscles are six muscles that originate from the orbit wall and insert into the outer layer of the eyeball, which allows for precision movements. List these six muscles:

A child was involved in an automobile collision. She was not wearing a safety restraint, and her chin struck the dashboard hard. When the physician looked into her auditory canal, he could see into herthroat. What do you infer from this about the nature of her injury?
1.) The middle ear chamber is an air-filled “hole in the head”, which is adapted to allow free movement of the tympanum as it vibrates. Unless the pressure in the chamber is equal to atmospheric pressure outside, the tympanum will be stretched outward or inward, impeding its vibration and causing discomfort or pain. When moving up in the elevator of a tall building, the surrounding atmospheric pressure is: a) increasing causing air to enter the middle ear chamber through the Eustachian tube. B.) increasing causing air to enter the middle ear chamber through the auditory canal C.)decreasing causing air to leave the middle chamber through the Eustachian tube D.) decreasing causing air to leave the middle ear chamber through the auditory canal

Sound waves enter the external auditory canal and cause vibrations in structures and fluids of the ear. Identify in order the structures and fluids that vibrate in the pathway from the external auditory canal to the spiral organ ofCorti.
Order the following structures rostral to caudal: pons, mammillary bodies, optic chiasm, and hypothalamus.
Young children usually have a fair degree of hyperopia. As they grow, their eyeballs lengthen and the hyperopia usually clears up. Given what you know about accommodation, explain why young children, though hyperopic, don’t need glasses.
Describe how accommodation changes the state of the eye in order to focus on objects at different distances. Make sure to describe the resting state of the eye, the role of the relevant muscles, and the state of the eye when focusing on nearby objects and faraway objects.
All of the following except the nerve begin or end in the orbit.a. opticb. oculomotorc. trochleard. abducense. accessory
The inner ear is responsible for both hearing and balance. One of the diseases affecting the inner ear is Meniere's disease. Affected individuals often experience vertigo, among other symptoms. Vertigo is a sensation that the surrounding is spinning or swaying in the absence of any body movement. Which of the following rows correctly identifies the affected structure and process in individuals experiencing vertigo? Select one: a. Structure Process Semicircular canals Rotational equilibrium b. Structure Process Semicircular canals Gravitational equilibrium c. Structure Process Organ of Corti Gravitational equilibrium d. Structure Process Organ of Corti Rotational equilibrium
