  1. Dilation of pupil

  2. Inhibition of peristalsis

  3. Elevation of blood pressure

  4. Stimulation of saliva secretion


Correct Option: D

Cutaneous plexus and papillary plexus consist of

  1. A network of arteries providing dermal supply

  2. Network of nerves providing dermal sensation

  3. Specialized cells for cutaneous sensation

  4. Gland cells that release cutaneous secretion


Correct Option: A
Explanation:
Cutaneous plexus is a network of arteries present along the border of hypodermis. These arteries supply blood to the fatty tissue of the hypodermis and deep parts of dermal layer including capillaries of hair follicles, sweat glands and sebaceous glands. Papillary plexus is another network of small arteries which supply blood to the dermal layer.
So, the correct answer is 'A network of arteries providing dermal supply'.
