, 1.What is a clear, watery fluid found in the anterior and posterior chambers of
i i i i i i i i i i i i i



the eye? i i




A. Vitreous humor i

Answer: D i




Rationale: Aqueous humor is a clear, watery fluid similar in composition
i i i i i i i i i i



blood plasma and is commonly found chambers. The posterior cavity, locat
i i i i i i i i i i i



dorsal to the lens, contains the (A) vitreous humor, a thick, clear, gelat

2. What is correct about the aqueous humor?i i i i i i




A. It balances absorption and pressure in the anterior chamber
i i i i i i i i




B. It is secreted by the epithelium of the ciliary bodies
i i i i i i i i i




C. Its inability to circulate freely can cause elevated intraocular pressure D. All of the
i i i i i i i i i i i i i



above
i




Answer: D i




Rationale: All three choices describe how the aqueous fluid forms and
i i i i i i i i i i



circulates in the eye. The aqueous humor develop into an increased
i i i i i i i i i i i




intraocular pressure which may lead to blindness when the pressure is
i i i i i i i i i i i



transmitted to

3. i i i i i i




A. Neutrophil
B. Lymphocytes
C. Eosinophil
D. Monocytes

, Answer: B i




Rationale: (A) Neutrophils are capable of phagocytosis, or destruction of
i i i i i i i i i



bacteria. (B) Lymphocytes offer media antigen-antibody reactions. (C)
i i i i i i i i




i Eosinophils are phagocytes that protect you from parasites. (D) Monocytei i i i i i i i i

4. When a person is seen walking in heels, the ankle is described as being in
i i i i i i i i i i i i i i



what position?
i i




A. Plantar flexion i




B. Dorsiflexion
C. Eversion
D. Abduction

Answer: A i




Rationale: (A) Plantar flexion is the movement which decreases the ang i i i i i i i i i i



between the sole of the foot and the dancing. (B).Dorsiflexion decreases th
i i i i i i i i i i i i



angle between the dorsum of the foot and the leg (C) Eversion is a turni
i i i i i i i i i i i i i i i




i turning of the foot outward at the ankle. (D) Abduction refers to a motio
i i i i i i i i i i i i i



i that pulls a body part away from th arms when you open them out like a bird
i i i i i i i i i i i i i i i i

C. Standing erect with palms facing forward and thumbs pointing towards the body
i i i i i i i i i i i




D. Standing erect with palms facing down and thumbs pointing away from the body
i i i i i i i i i i i i




Answer: B i




Rationale: A correct anatomical position is exactly as described in answ

6. A frontal section divides the body into:
i i i i i i

, A. Right and left parts
i i i




B. Anterior and posterior parts
i i i




C. Midsagittal and median section i i i




D. Superior and inferior parts i i i




Answer: B i




Rationale: Frontal or coronal plane divide the body into front and back (al i i i i i i i i i i i i



called dorsal and ventral or posteri describes the sagittal or lateral plane
i i i i i i i i i i i i



left to right cut. (C) explains that the plane may be in the centre of the
i i i i i i i i i i i i i i i i




i (midsagittal). (D) refers to transverse planes, also known as the axial i i i i i i i i i i



i horizontal planes, dividing the body into and bottom sections also called t i i i i i i i i i i i



i superior and inferior sections. i i i




7. Which of the following is seen mostly inside the epiphyses of each long bone
i i i i i i i i i i i i i




A. Yellow marrow i




B. Cartilage
C. Spongy bone i




D. Compact bone i




Answer: C i




Rationale: A typical long bone has epiphyses which are at the ends of the i i i i i i i i i i i i i



bone, and consist of internal spongy b
i i i i i i i



(D) compact bone. (A) Yellow marrow, which is mainly made up of fat cells,
i i i i i i i i i i i i i



are found inside a hollow medullary and not the epiphyses. (B) Cartilage is
i i i i i i i i i i i i i




found between bones.

C. It is attached to the upper part of the tibia i i i i i i i i i




D. it is attached to the upper part of the femur i i i i i i i i i




Answer: D i




Rationale: Trochanter is a very large, blunt, upper part of the femur which i i i i i i i i i i i i




i connects to the hip. (A) describes a c arm. (B) also describes connection th
