    1.Neural crest cells give rise to
    a)cells of renal medulla
    b)cells of adrenal cortex
    c)Preganglionic parasympathetic cell bodies
    d)postganglionic sympathetic cell bodies
    e)preganglionic sympathetic cell bodies


    2.Best charac of STEROID hormones
    1.stored in secretory granules
    2.binds to intracellular receptors
    3.synthesized in precursor form
    4.act by generatin second messenger
    5.usually transport unbound in plasma.

    1. Which of the following explains why the digestive action of salivary amylase continues for some time after swallowing?
    a. Gastric HCI increases the digestive action of amylase
    b. Gastric mucin lubricates the bolus and assists amylase activity
    c. The amylase inside the bolus is protected from the inactivating action of gastric HCI.
    d. Water absorption by the stomach concentrates amylase and make its action more effective


    2.Where is Sanger method of cloning used?


    3. The GREATER the horizontal overlap (overjet) of the anterior teeth, then the
    a. shorter the cusps of the posterior teeth
    b. greater the intercondylar distance
    c. lesser the intercondylar distance



    4.Which statement about blood vessels of the brain is false:
    a. the anterior cerebral artery is located in the longitudinal fissure
    b. the middle cerebral artery is located in the lateral fissure
    c. the superior cerebellar artery is a branch of the vertebral artery
    d. the two vertebral arteries join to form the basilar artery
    e. the anterior communicating artery connects the two anterior cerebral arteries


    5..in essential hypertension , which of the following represents the classic autopsy finding in the kidney?
    a.pyelonephritis
    b.glemerulonephritis
    c.begin nephrosclerosis
    d.renal artery stenosis
    e.renal infarction



    6.A blow that shatters the coracoid process wil have a direct effect on which of the following pairs of the muscles?
    a.serratus anterior and pectoralis major
    b.subscapular and pectoralis major
    c.biceps brachi and pectoralis major
    d.subscapularis and subclavius
    e.deltoid and subclavius



    8.The clearance of several substances was measured at a constant glomerular filtration rate and constant urine flow rate, but at increasing plasma concentrations of the substance. Under these conditions, clearance will increase at high plasma concentrations for which of the following substances?
    A. Creatinine
    B. Mannitol
    C. Penicillin
    D. Phosphate
    E. Urea

    9.Each of the following is charac of creatinine EXCEPT one. Which one is the exception?

    a) Freely filtered
    b) Slightly secreted
    c) Slightly reabsorbed
    d) produced endogenously at a constant rate



    10.which of the following statements BEST describe GTP-binding proteins(G-Proteins)?
    a.are important components of steroid harmone signal transduction
    b.catalize the reaction which produces diacylglycerol
    c.are tightly bound to adenylate cyclase
    d.usually inactive protein kinase C
    e.are membrane proteins

    1.Neural crest cells give rise to
    a)cells of renal medulla- ans:chromaffin cells of the adrenal medulla
    b)cells of adrenal cortex
    c)Preganglionic parasympathetic cell bodies
    d)postganglionic sympathetic cell bodies
    e)preganglionic sympathetic cell bodies


    2.Best charac of STEROID hormones
    1.stored in secretory granules
    2.binds to intracellular receptors- ans: steroid hormones are lipophillic so they cannot be stored or preformed and pass through cell membranes of target cells.
    3.synthesized in precursor form
    4.act by generatin second messenger
    5.usually transport unbound in plasma.

    ....
    1.neural crest cells give rise to cells of the autonomic ganglia and only the post ganglionic nr fibres(whether symp/Parasym) would hav their cell bodies in the autonomic ganglia...
    *Remember the choice given is "renal medulla" , not adrenal medulla , my friend....
