In the plasma membrane, glycolipids are usually situated in:

 # In the plasma membrane, glycolipids are usually situated in:

a. Cannot be predicted, it varies according to the cell types. 

b. Inner leaflet of plasma the membrane. 

c. Outer leaflet of the plasma membrane. 

d. Evenly distributed in both outer and inner leaves of plasma membrane. 

The correct answer is C. Outer leaflet of the plasma membrane.

Glycolipids are found on the outer leaflet of cellular membranes where it play not only a structural role to maintain membrane stability but also facilitates cell to cell communication acting as receptors, anchors for protein and regulators of signal transduction. Cell surface carbohydrates play major roles in cell substrate recognition in oncogenesis, cell adhesion in metastasis.

Nerve of pterygoid canal is also known as:

 # Nerve of pterygoid canal is also known as:

A. Vidian nerve

B. Radial nerve

C. Musician’s nerve

D. None of the above

The correct answer is a. Vidian nerve.

The vidian nerve (also known as the nerve of the pterygoid canal) is formed by the union of the deep and greater petrosal nerves, the latter being a branch of the facial nerve at the level of the geniculate ganglion.

The nerve of the pterygoid canal (Vidian nerve) is formed by the junction of the greater petrosal nerve and deep petrosal nerve, which passes from the foramen lacerum to the pterygopalatine fossa through the pterygoid canal.
