Medical Entrance Test (Set-I) Zoology
#1. Pacemaker of heart is :
SA node is heart of heart / natural pacemaker with maximum impulse generation perminute.
AV node is pacemaker / nodal rhythm.
Bundle of his is non rhythmic.
Purkinje fibers is also non rhythmic with fastest conduction (4m/s)
#2. ATPase enzyme needed for muscle contraction is located in :
#3. Find out wrongly matched pair:
Non-keratinized stratified squamous epithelium-@NaHaS (Nail, Hair, Skin). Ciliated epithelium-Oviduct, Fallopian tube, Cavity of CNS (Ependymal cavity), Respiratory Tract (upto terminal bronchioles). Squamous epithelium-@ABCDE (Alveoli, Bowman’s capsule, Coelomic epithelium, Descending loop of Henle’s, Endothelium).
#4. Excessive stimulation of vagus nerve in human leads to:
Vagus nerve is a part of parasympathetic nervous system.
#5. Voluntary muscle co-ordination is under control of
Motor area of frontal lobe control voluntary movement of muscle.
@OE PaST TEN
Occipital lobe-Eye
Parietal lobe-skin, Taste
Temporal lobe-Nose and Ear
#6. Each Hemoglobin molecule contain…….atoms of oxygen?
1Hb = 4O2. 4 molecules of O2 =8 atoms of O2
#7. Bowman`s membrane is present in :
Bowman`s gland: Present in nose (mucous production)
Bowman`s capsule: Present in nephron
#8. In mammals, significant of vagus nerve in human leads to :
Renin is secreated by juxtaglomerular cell of nephron Rennin is secreated by peptic cell / chief cell / Zymogen cell of stomach in inactive form(prorenin).
#9. The pH of blood in arteries and veins:
Solution : Due to oxygenated blood in artery, it is slightly basic in nature as compared to normal pH deoxygenated blood in veins, so it is slightly acidic in nature as compared to normal pH.
#10. Erythropoiesis starts in :
Erythropoiesis (formation of EBC) starts in Yolk sac>Liver>Spleen>Red bone marrow
