The end organs of Ruffini are receptors of :
1 Heat
2 Cold
3 Pressure
4 Touch
Explanation:
A The end organ of Ruffini are external receptor of heat present in skin. The sensation of heat is perceived by Ruffini is corpuscles located in deep layer of dermis. They are as thermoreceptors that are sensitive to heat which respond for a long time.

Organ of Jacobson helps in
1 Touch
2 Vision
3 Smell
4 Hear
Explanation:
C Jacobson's organ is an olfactory chemoreceptor organ. It helps the animal to smell sex pheromones or help to hunt its prey. Its present as a vestigial organ in human beings. Jacobson's organ is also called as the vomeronasal organ. It is a patch of sensory cells within the main nasal chamber that detects heavy moisture-borne odour particles.

Which one remain unaffected, if vagus nerve is injured in human?
1 Gastrointestinal movements
2 Tongue movements
3 Cardiac movements
4 Pancreatic activities
Explanation:
B Vagus - Distribution Function \(\downarrow\) Larynx, Lungs, heart, Stomach, intestine Visceral sensation and movements - Vagus nerve does not affect tongue movement. The vagus nerve is responsible for the regulation of internal organ functions such as digestion, heart rate and respiratory rate as well as vasomotor activity.

Which one of the following is correctly matched pair of the given secretion and its primary role in human physiology?
1 Seburtise - Sexual attraction
2 Sweat - Thermoregulation
3 Saliva - Tasting food
4 Tears - Excretion of salts
Explanation:
B Sweating occurs when the body temperature increases. As sweat evaporates from the skin surface energy is lost from the body as latent heat of vaporization and in this away sweat reduces body temperature sweat glands are coiled tubular glands situated in the dermis and connected to a sweat duct which open as pore on the surface of the skin. These secrete sweat 0.1 to \(0.4 \%\) contains sodium chloride, sodium acetate and urea.
