Explanation:

• Question 151:
• The macula is a yellow - spot in the retina lateral to the optic nerve. The iris is the colored part of the eye that controls the pupil size. The lens is a transparent structure that helps focus light. The optic disc is where the optic nerve exits the eye and has no photoreceptor cells (blind spot).
• Question 152:
• “Quadri -” and “tetra -” both mean four. “Plegia” means paralysis. So, Quadri/plegia (paralysis of four limbs) is the same as tetra/plegia. Cephal/algia means headache. Mono/plegia means paralysis of one limb. Psycho/genic relates to psychological origin.
• Question 153:
• “Occiputo -” refers to the back of the head. The palm of the hand has its own root words (e.g., palmo -). The sole of the foot has roots like plantar - or podo - (related to the foot in a broader sense). The back of the neck has different anatomical root terms.

Answer:

• Question 151: macula
• Question 152: tetra/plegia
• Question 153: back of the head
