o (d) Yellow colour in the sclerae, which may indicate jaundice.
- Which functions belong to the liver?
• (a) The liver metabolizes carbohydrates, lipids, and proteins.
o (b) The liver completes the digestion of nutrients.
o (c) The liver acidifies and hydrolyses protein to a mixture.
o (d) The liver secretes enzymes and hormones into the blood stream.
- Which of the following enzymes is not a liver enzyme?
o (a) Alanine transaminase or ALAT.
o (b) Aspartate transaminase or ASAT.
o (c) Creatine kinase or CK.
o (d) Alkaline phosphatase or ALP.
C
When kidneys are damaged, creatine is freed
- Which statement(s) is/are true?
I Pain and propriocepsis belong to the sensory input of the brain.
II Different parts of the body are projected on the sensory cortex.
Both statements are true. propioscepsis = position coordination of body
- Which of the following statements are true with regards to cranial nerves
A. There are 13 cranial nerves
B. Facial nerve supplies the sensation on the face
C. Trochlear nerve is responsible for hearing
D. Optic nerve damage leads to short sightedness
None are true
A. there are 12 cranial nerves
B. Facial nerve is a cranial nerve that controls facial expression
C. Trochlear is a cranial nerve responsible for eye movement
D. shortsightedness is caused by lens distortion or lensmuscle malfunction
- A CT-scan of the brain shows a dark grey hyperdense mass. Which neurological problem is most plausible?
o (a) Brain tumour.
• (b) Brain infarction.
o (c) Transient Ischaemic Attack (TIA).
o (d) Acute bleeding.
- A CT-scan of the brain shows a white hyperdense mass. Which neurological problem is the most plausible?
o (a) Brain infarction.
o (b) Transient Ischaemic Attack (TIA).
• (c) Acute bleeding.
o (d) Brain tumour.
- Which type of cells form part of the nervous system?
o (a) Glial cells and Schwann cells.
o (b) Neurons.
o (c) Connective tissue cells and blood vessel cells
o (d) All of the above answers are true.
D
Glial cells protect nerve cells, insulates them, provide nutrients, destroy pathogens, and removes dead nuerons.
Schwann cells are a type of glial cells
- What is the Frank-Starling mechanism (also known as Starling’s law)?
o (a) The greater the volume of blood ejected by the heart during systolic contraction, the lower the diastolic blood pressure.
o (b) The greater the end-diastolic volume, the greater the volume of blood ejected by the heart into the aorta
o (c) The lower the systolic blood pressure, the greater the volume of blood ejected by the heart into the pulmonary trunk.
o (d) The higher the systolic blood pressure, the greater the volume of blood ejected by the heart to the brain.
B
blood pressure does not per se correlate to blood volume
systolic = upper blood pressure
diabolic = lower blood pressure
- Which statement(s) is/are true?
I. The intrinsic regulation of the heart involves neural and hormonal control.
II. The Frank-Starling mechanism is involved in the extrinsic regulation of the heart.
None of the statements are true.
Frank-Starling is intrinsic, works from the inside
Hormones regulate heart as an external factor
- What is the right order of an electrical stimulus through the heart?
o (a) Sinus node - His bundle - atrio ventricular node - Purkinje system.
o (b) Sinus node - atrio ventricular node - His bundle - Purkinje system.
o (c) Purkinje system - atrio ventricular node - sinus node - His bundle.
o (d) Purkinje system - sinus node - atrio ventricular node - His bundle.
B
- Which statement about the circulatory system is true? In the systemic circulation the heart pumps
o (a) oxygenated blood from the heart to the body while the pulmonary circulation pumps oxygen-depleted blood from the heart to the lungs.
o (b) oxygenated blood from the heart to the lungs while the pulmonary circulation pumps oxygen-depleted blood from the heart to the body.
o (c) oxygen-depleted blood from the heart to the body while the pulmonary circulation pumps oxygenated blood from the heart to the lungs.
o (d) oxygen-depleted blood from the heart to the lungs while the pulmonary circulation pumps oxygenated blood from the heart to the body.
A
- Which valves are involved in the pulmonary circulation?
o (a) Only the pulmonary semilunar valves.
o (b) The pulmonary semilunar valves and the tricuspid valve.
o (c) The pulmonary semilunar valves and the bicuspid valve.
o (d) The pulmonary semilunar valves and the aortic semilunar valves.
B
tricuspid valve = right atrioventricular valve
bicuspid valve = left one (mitral valve)
- Which statement(s) is/are true about the cardiac cycle?
I. Blood moves through the circulatory system from areas of lower to higher pressure.
II. The systolic blood pressure indicates when the heart contracts to pump deoxygenated blood to the lungs and oxygenated blood to the body.
Only statement II is true.
systolic bloodpressure is generated by the left chambers, pumping blood into the aorta and lungs.
- What is the medical term for a heart rate larger than 100 beats per minute?
Tachycardia
