#1. Erythropoiesis starts in :

c) Kidney

d) Red bone marrow

a) Liver

b) Spleen

Erythropoiesis (formation of EBC) starts in Yolk sac>Liver>Spleen>Red bone marrow

#2. Excessive stimulation of vagus nerve in human leads to:

c) Excessive digestion

d) Irregular contraction of diaphragm

b) Peptic ulcer

a) Hoarse Voice

Vagus nerve is a part of parasympathetic nervous system.

#3. The pH of blood in arteries and veins:

d) Variable in both

c) Same in both arteries and veins

a) Higher in veins and lower in arteries

b) Higher in arteries and lower in 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.

#4. Find out wrongly matched pair:

d) Columnar epithelium-Peritoneum of body cavity

b) Ciliated epithelium-Bronchioles

a) Squamous epithelium-Skin of frog

c) Glandular epithelium-Salivary gland

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).

#5. Pacemaker of heart is :

b) SA node

d) Tricuspis Valve

c) SV node

a) AV node

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)

#6. Bowman`s membrane is present in :

Nephron

Nose

Ear

Cornea

Bowman`s gland: Present in nose (mucous production)

Bowman`s capsule: Present in nephron

#7. Each Hemoglobin molecule contain.......atoms of oxygen?

c) 6

d) 8

a) 2

b) 4

1Hb = 4O2. 4 molecules of O2 =8 atoms of O2

#8. ATPase enzyme needed for muscle contraction is located in :

a) Actin

d) Tropomyosin

b) Myosin

c) Troponin

#9. Voluntary muscle co-ordination is under control of

Medulla oblongata

Cerebellum

Hypothalamus

Cerebral hemisphere

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

#10. In mammals, significant of vagus nerve in human leads to :

a) Renin

c) Pancreatic amylase

b) Rennin

d) Invertase

Renin is secreated by juxtaglomerular cell of nephron Rennin is secreated by peptic cell / chief cell / Zymogen cell of stomach in inactive form(prorenin).
