Questions: 16 · 10 minutes
1. The sclera must withstand pulling forces arriving from several directions as eye muscles move the eyeball. Which tissue is best suited to this role?
Dense irregular connective tissue
Hyaline cartilage
Smooth muscle tissue
Adipose connective tissue
2. A retinal cell detects light and passes a signal toward the brain. Which major tissue category best matches this function?
Connective tissue
Muscle tissue
Nervous tissue
Covering epithelium
3. David Bowie's eyes often appeared to be different colors. What chiefly produced that appearance?
The two irises naturally contained different pigments, called complete heterochromia
One pupil remained enlarged after an eye injury, a condition called anisocoria
He routinely wore one dark cosmetic contact lens
One iris was partly absent from birth, a condition called aniridia
4. Why is a small amount of fluid normally found between the parietal and visceral layers of a serous membrane?
It anchors the organ rigidly to the cavity wall
It supplies oxygen by replacing nearby blood vessels
It creates voluntary contractions of the organ
It reduces friction as the organ moves
5. Which serous membrane lines the abdominopelvic cavity and covers many of its organs?
Conjunctiva
Pleura
Pericardium
Peritoneum
6. A superficial corneal abrasion damages the cornea's outer protective layer. Which tissue has been affected?
Nonkeratinized stratified squamous epithelium
Simple squamous mesothelium
Transitional epithelium
Pseudostratified ciliated columnar epithelium
7. Elizabeth Taylor's unusually prominent double row of eyelashes is associated with which term?
Distichiasis
Trichiasis
Blepharitis
Madarosis
8. Which description best distinguishes a serous membrane from the membrane covering the exposed surface of the eye?
It opens directly to the exterior and secretes protective mucus
It lines a closed ventral body cavity and covers organs within that cavity
It forms the dry external covering of the body
It lines a movable joint and lacks an epithelial layer
9. Bright light triggers constriction of the pupil without conscious effort. Which tissue in the iris produces that movement?
Skeletal muscle
Cardiac muscle
Smooth muscle
Dense regular connective tissue
10. A learner claims that the membrane over the front of the eye must be a serous membrane because it is moist. Which correction is accurate?
The conjunctiva is serous because it covers part of the eyeball
The cornea forms a visceral serosa while the eyelid forms a parietal serosa
The tear film turns the exposed eye surface into a closed serous cavity
The conjunctiva is a mucous membrane; the eye is not enclosed by a serous membrane
11. Inflammation causes painful friction between the surface of a lung and the inner chest wall. Which two layers are rubbing?
Visceral pericardium and parietal pericardium
Visceral pleura and parietal pleura
Visceral peritoneum and parietal peritoneum
Conjunctival epithelium and corneal epithelium
12. The characteristic appearance of Forest Whitaker's left upper eyelid is commonly described using which term?
Cataract
Strabismus
Ptosis
Conjunctivitis
13. Following a 1954 car accident, what happened to Sammy Davis Jr.'s injured left eye?
A corneal transplant fully restored its sight
A tinted contact lens was used while the eye healed
A detached retina was repaired without loss of the eye
The eye was surgically removed and replaced with a prosthetic eye
14. Under a microscope, a serous membrane's mesothelium appears as one layer of thin, flat cells. How is this epithelium classified?
Simple squamous epithelium
Stratified cuboidal epithelium
Pseudostratified columnar epithelium
Transitional epithelium
15. During heart surgery, a surgeon reaches the serous membrane associated with the heart. What is it called?
Pleura
Peritoneum
Serous pericardium
Synovial membrane
16. A patient feels pain when inflamed membrane layers rub as the lungs expand. Which serous membrane is involved?
Peritoneum
Pleura
Pericardium
Conjunctiva
