The portal triad in the liver consists of which three structures?

Which nerve provides sensory innervation to the lateral surface of the thigh?
Answer: Lateral femoral cutaneous nerve
The lateral femoral cutaneous nerve (L2-L3) provides sensory innervation to the anterolateral thigh; its compression causes meralgia paresthetica.
The zona glomerulosa of the adrenal cortex primarily secretes which hormone?
Answer: Aldosterone
The outermost zona glomerulosa secretes aldosterone, which regulates sodium retention and potassium excretion.
Which structure passes through the foramen magnum?
Answer: Medulla oblongata
The medulla oblongata passes through the foramen magnum as the brainstem continues into the spinal cord.
The saphenous nerve is a branch of which nerve?
Answer: Femoral nerve
The saphenous nerve is the longest branch of the femoral nerve, providing sensory innervation to the medial leg and foot.
Which structure separates the posterior cranial fossa from the middle cranial fossa?
Answer: Tentorium cerebelli
