GENERAL KNOWLEDGE

Detailed explanation-1: -Touch is the first of our senses to develop, providing us with the sensory scaffold on which we come to perceive our own bodies and our sense of self. Touch also provides us with direct access to the external world of physical objects, via haptic exploration.

Detailed explanation-2: -Sight comes first, because the eye is such a specialized organ. Then come hearing, touch, smell, and taste, progressively less specialized senses.

Detailed explanation-3: -Sensations begin as signals generated by touch receptors in your skin. They travel along sensory nerves made up of bundled fibers that connect to neurons in the spinal cord. Then signals move to the thalamus, which relays information to the rest of the brain.

Detailed explanation-4: -Your baby’s sense of smell is one of the first senses to develop in the womb. The olfactory (smell) receptors begin to develop as early as 8 weeks gestation and become fully functional at about 24 weeks. 1 This means that your baby is born with a completely developed sense of smell!
