Sample UMF Iași Dentistry Admission Practice Questions

Try these sample questions to review concepts for the UMF Iași Dentistry Admission exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 61+ question experience with AI tutoring.

1What is the primary organic component of the extracellular matrix of human bone and dentin?

A.Type I collagen

B.Type II collagen

C.Keratin

D.Elastin

Explanation: Type I collagen is the main collagen of bone and dentin. It contributes tensile strength, while deposited mineral chiefly contributes hardness and resistance to compression.

2Which of the following salivary enzymes initiates the chemical digestion of dietary carbohydrates in the human oral cavity?

A.Alpha-amylase (ptyalin)

B.Lingual lipase

C.Pepsin

D.Maltase

Explanation: Salivary alpha-amylase starts starch digestion by hydrolysing internal alpha-1,4 bonds. It produces smaller carbohydrates rather than completing digestion to absorbable glucose in the mouth.

3Which hormone produced by the thyroid gland decreases plasma calcium levels by inhibiting osteoclastic bone resorption?

A.Calcitonin

B.Parathyroid hormone

C.Thyroxine (T4)

D.Triiodothyronine (T3)

Explanation: Thyroid C cells release calcitonin in response to increased blood calcium. Its inhibition of osteoclast activity reduces calcium release from bone; PTH has the opposing overall effect on blood calcium.

4During muscle contraction in skeletal muscle fibers, calcium ions bind directly to which regulatory protein complex?

A.Troponin C

B.Tropomyosin

C.Myosin light chain

D.Actin

Explanation: Calcium binds to troponin C in skeletal muscle. This changes the regulatory complex's shape and moves tropomyosin away from actin's myosin-binding sites, permitting cross-bridge formation.

5Which ABO blood group normally has neither A nor B antigens on its erythrocytes but has both anti-A and anti-B antibodies in plasma?

A.Group O

B.Group A

C.Group B

D.Group AB

Explanation: Group O erythrocytes lack both A and B antigens. The plasma normally contains antibodies against both, so red-cell antigens and plasma antibodies must be distinguished when interpreting an ABO group.

6What is the functional unit of the human kidney responsible for blood filtration, tubular reabsorption, and urine concentration?

A.Nephron

B.Renal pyramid

C.Major calyx

D.Glomerular capsule

Explanation: A nephron comprises a renal corpuscle and renal tubule. Filtration begins in the corpuscle, while tubular reabsorption and secretion modify the filtrate to help form urine.

7During normal quiet inspiration in a healthy adult, which event initiates the expansion of the thoracic cavity?

A.Contraction and flattening of the diaphragm

B.Contraction of the interosseous internal intercostals

C.Relaxation of external intercostals

D.Contraction of abdominal rectus muscles

Explanation: Diaphragm contraction increases thoracic volume and expands the lungs. Alveolar pressure briefly falls below atmospheric pressure, so air enters down the pressure gradient.

8Which portion of the human brainstem contains the vital cardiovascular, vasopressor, and respiratory rhythmicity reflex centers?

A.Medulla oblongata

B.Midbrain (mesencephalon)

C.Pons

D.Diencephalon

Explanation: The medulla contains centres involved in cardiovascular regulation and the basic respiratory rhythm. It also participates in protective reflexes such as coughing and swallowing, rather than conscious voluntary motor planning.

9Which photoreceptor cells of the human retina are specialized for photopic vision, high spatial visual acuity, and color discrimination?

A.Cones

B.Rods

C.Amacrine cells

D.Bipolar cells

Explanation: Cones support colour vision and high visual acuity in bright light. Their three pigment classes have overlapping wavelength sensitivities, and their dense foveal concentration supports detailed central vision.

10Which layer of the adrenal gland produces mineralocorticoids, principally aldosterone, in response to hyperkalemia and angiotensin II?

A.Zona glomerulosa

B.Zona fasciculata

C.Zona reticularis

D.Adrenal medulla

Explanation: The zona glomerulosa is the outer adrenal cortical layer and produces aldosterone. Aldosterone increases renal sodium reabsorption and potassium secretion, contributing to electrolyte and fluid regulation.
