The mitral (bicuspid) valve controls blood flow between the left atrium and left ventricle.
Question 3: Which muscle is primarily responsible for dorsiflexion of the foot?
- Gastrocnemius
- Tibialis anterior (Correct answer)
- Peroneus longus
- Soleus
Correct answer: Tibialis anterior
The tibialis anterior is the primary dorsiflexor of the foot, lifting the foot upward toward the shin.
Question 4: What type of epithelium lines the urinary bladder?
- Simple squamous
- Pseudostratified columnar
- Transitional (urothelium) (Correct answer)
- Stratified squamous
Correct answer: Transitional (urothelium)
Transitional epithelium (urothelium) lines the urinary bladder and can stretch as the bladder fills with urine.
Question 5: The femoral triangle is bounded superiorly by which structure?
- Inguinal ligament (Correct answer)
- Sartorius muscle
- Adductor longus
- Pectineal line
Correct answer: Inguinal ligament
The inguinal ligament forms the superior (base) boundary of the femoral triangle.
Question 6: Which cranial nerve is responsible for the gag reflex (afferent limb)?
- Cranial nerve V (Trigeminal)
- Cranial nerve IX (Glossopharyngeal) (Correct answer)
- Cranial nerve X (Vagus)
- Cranial nerve XII (Hypoglossal)
Correct answer: Cranial nerve IX (Glossopharyngeal)
Cranial nerve IX (glossopharyngeal) provides the afferent limb of the gag reflex by sensing the posterior pharynx.
Question 7: Which layer of the skin contains the Meissner's corpuscles?
- Stratum corneum
